Labelexpo 2023 reaffirms its significance!

Labelexpo 2023 reaffirms its significance!

Absence makes the heart grow fonder! There was a general perception that the impact of a fierce pandemic, the Finnish Paper Mills strike, Ukraine war, shortages and rising raw material prices, difficult logistics and increased travel costs have left the market sentiments bruised. There was strong narrative doing the rounds in the labels industry that Labelexpo Europe 2023 at Brussels will lose its sheen and may not deliver the desired results. Contrary to all perceptions the show was a huge success. The numbers may have been slightly lower than the previous years, but the quality of turnout brought cheer to the faces of exhibitors. The proof of that is given by the reported rebook rate for the next edition of this important event by Tarsus, announced at a whopping 96%! Labelexpo Europe 2023 was spread over 9 halls covering 35889 square meters. 36588 visitors flocked to the show, coming from 138 countries. Most stands reported robust enquiries or sales from established and serious printers from around the world. Though the aisles were not as crowded as in previous shows, the stands were busy. That is exactly what exhibitors expect from a globally renowned show. I cite a personal experience, I had to conduct an important meeting with one of our company’s several principals. Despite visiting their stand on all days at various times, the concerned person was busy with clients, finally I had to ask him to come to another meeting point other than his stand, so that we could discuss our project in peace. Such was the deliverance of Labelexpo 2023.

The Indian presence; The Indian labels and packaging industry has been continuously growing at steady pace to reach a position of stability and strength. The Indian visitors to labelexpo have also transformed. Earlier we saw many of those who mixed their visit with tourism, so the interest was diluted, and the enquiries lacked seriousness. This trend is seen as changing, given the increased travel costs and technologies evolving in different packaging segments, the smaller printers prefer to visit the domestic editions of Labelexpo. 

In 2005, my company was the only one from India to exhibit at Labelexpo Europe in Brussels, over years the number of Indian exhibitors has been growing. Indian producers of materials, machines and tooling have improved in quality to match global levels and offer their products in the international marketplace. 

From just the one exhibitor from India displaying labelstock in 2005 they reached 14 exhibitors in 2017, and in 2023 the number of Indian exhibitors grew to 26. This number included several label press manufacturers, manufacturers of coaters and laminators, raw material suppliers, tooling manufacturers, etc. In fact, registering their presence in all segments of label manufacturing. As for the visitors, it is an even more interesting result. In 2019 2% of the total of 37903 visitors were from India.

This works out to over 750 visitors. This figure has swelled! In Labelexpo Europe 2023. Indian visitors were 3.9% of the total of 36588 visitors and this works out to over 1400 visitors, almost double the number. We can imagine the dynamism and steady growth of “make in India” concept. The Indians are now quick learners who visit these shows and become adapters of global technologies to produce and offer to the world.

Diverse technologies displayed: Labelexpo global series was in the initial stages aimed at growth of stickers that had evolved as self-adhesive labels. The earliest web label presses were largely coming from eastern part of the World as 4 or 5-inch-wide flatbed letterpress machines for printing labels in roll form to eventually transform with development of label applicators, it led to automation in packaging lines.

Development and introduction of rotary flexographic label presses brought a paradigm shift as it provided better speed of printing.

Since the web width in the earliest stages was small, the industry eventually started being referred to as narrow web label industry. The rest is history. With evolution and development of prepress printing speeds and quality also improved making the technology widely acceptable. Printing widths increased to 10 inches or 250 mm and had for quite some time settled at 330mm.

Speeds that were just 5 or 6 meters per minute in the beginning with the flatbed presses, have reached up to 200 meters per minute and more. The narrow web label industry flourished and kept growing. With time label technologies have undergone a sea change. What was wet glue labels, transformed into self-adhesive labels but later the label grew towards various tangents. The label users started adopting a wide variety that includes wraparound labels, shrink sleeves, Inmold labels, heat transfer labels and many more. In the initial stages of transformation large multinational FMCG companies became users of wrap-around labels and shrink sleeves, because of the large volume they required, these became the product of the wide web rotogravure printing industry. With market changes happening, the need of smaller manufacturers and demand for short runs by marketing professionals, these diverse segments also became evident in the offerings of narrow web industry. 

The narrow started growing wider still, printing and converting evolved exponentially and became suppliers of not only to wide spectrum of labels but also flexible packaging, Lami-tubes and folding cartons. The flexo presses also transformed to be hybrid ones  employing combination of flexo, offset, gravure, screen and digital, etc.

At Labelexpo Europe 2023, one could witness displayed, a merger and combination of different printing technologies to produce excellence in print of labels and packaging. This was substantially exhibited by industry stalwarts like Gallus, Omet, Nilpeter, Mark Andy, Bobst, Weigang, Lombardy, etc. who displayed their finest web printing and converting equipment. It is interesting that waste reduction and sustainable manufacturing practices to reduce carbon footprint are becoming imperative for all responsible machine builders.

Overview: Material suppliers like Avery Dennison, UPM Raflatac and Fedrigoni displayed their vast ranges of labelstocks with an evident effort towards sustainability. Many did talk of linerless and the initial developments they have made but the actual linerless self-adhesive label for mass usage is still a far cry. 

As mentioned before, from the just one Indian Labelstock producer in 2005, there were five Indian labelstock producers at the show, Jindal SMI, SticOn papers, MLJ, Shree Lamipack and Varshil. Looking at the number of visitors on stands it was clear that the focus of label fraternity is shifting from commodities to creativity, innovation and sustainability. While all labelstock companies had a steady flow of visitors, the Fedrigoni stand that offered specialty textured and decorative materials was extremely busy. 

A similar situation was observed at the Cartes stand whose displayed equipment offered amazing embellishments with various combinations of digital jet screen varnishing and printing, screen printing, laser die-cutting etc. The electronic integration in labels is another field that attracted the attention of forward-thinking printing companies. RFID insertion options for labels and packaging were displayed by many, some of whom include  Avery Dennison, Beontag, Muhlbauer, Delta Modtech, etc. Another aspect witnessed is the growing number of finishing equipment manufacturers, which clearly indicates the need for printing companies to produce more with less. The concept of printing at full machine speeds on their expensive presses and finishing offline makes available more time on their main printing presses. The futuristic digital printing equipment continues to evolve indicating it to become a dominant label printing technology in future, given the wider widths and faster speeds.

The hall number 8 with exhibitors led by HP, offered a vast variety of digital printing equipment. The increased display of finishing or digital finishing machines is also indicative of the increasing importance of digital printing, which in recent times has become a necessity for prosperous label printers. Running short runs needs offline finishing. else the digital presses with inline finishing will not only be expensive but will not be able to deliver production to their full capacity due to short runs and quick changeovers.

One thing that has become evident at Labelexpo Europe 2023 is that the narrow web label industry continues to go wider and evolve, increasing its footprints in other segments of packaging and it would not be out of place to mention that soon it  will be referred to as “Web label and package converting industry.”

The end of show was a nostalgic moment, people bidding farewell to Labelexpo in Brussel where so many wonderful memories, stories of success and friendships had been scripted. The label fraternity now looks forward to making another beginning with Labelexpo Europe 2025 in Barcelona, Spain.

My Walk through!

Written by Harveer Sahni, Chairman Weldon Celloplast Limited New Delhi India September 2023

Pamex 2023 justifies theme; “Convergence of print.”

Pamex 2023 justifies theme; “Convergence of print.”

Ever since 1450 when goldsmith Johannes Gutenberg invented the movable-type printing press, which started the Printing Revolution, printing technology has been evolving. The technology has come a long way from the first use of flat wooden blocks being inked and stamped on to paper to production of metal typesetting mechanizing the process. The history is very interesting and long. Printing process or technology has evolved in many forms of contact printing from flat bed to offset printing in sheet and roll to other forms of printing like rotogravure and  screen to finally reach the present-day non-contact digital printing without the need of blocks or plates and with just click of button from computer to print.

With time, labels and packaging evolved and there was a dire need to decorate the packages and labels to catch the attention of discerning customers. Embellishing processes have also been developed to become an inherent part of printing and converting process. These include varnishing, hot-foiling, cold-foiling, embossing, debossing, lamination, die-cutting etc. With the development of different printing technologies it became apparent that each technology has its own advantage. For high quality images to reproduce skin tones and vignettes, offset is preferred. For the desired pantone shades, flexo is preferred.

To achieve higher deposition of ink, screen printing delivers the desired results and to get the good metallic effects in printing with metallic inks, gravure printing is used. To produce personalization in print, have variable printing, to achieve track and trace information and security information, digital provides the option. The advent of organized retail and e-commerce becoming a part of our daily life, has brought about the need to bring the best of each technology together and achieve excellence in printing and packaging. The organisers of Pamex 2023 exhibition, All India Federation of Master Printers (AIFMP), in association with Print-Packaging.com saw immense value in adopting the theme “Convergence in Print” and delivering the importance of this theme to printers and other visitors to this prime show.

The theme was conveyed to the printers in the nation at different geographical venues in India  by the promoters. Roadshows with presentations by sponsors offering equipment with convergence in print and panel discussions were a part of these presentations. Technical presentations on technologies such as printed electronics were also a part of the roadshows. Diverse information and knowledge was delivered to attendees at locations like Bangalore, Pune, Guwahati, Indore and Haridwar.

The focused efforts by the team of AIFMP headed by President Ravi Joshi, Tushar Dhote and organizer Anil Arora of Print-Packaging.com produced a successful event. The final show Pamex 2023 held at Bombay Exhibition Centre Goregaon Mumbai on 27th-30th March 2023 was an immense success. 33,812 visitors and over 450 exhibitors thronged the venue and came from many countries around the world.

On the penultimate evening Pamex 2023 played host to a glittering awards ceremony at the Gala Exhibitors’ Evening. AIFMP decided to institute several new awards to add to the prestigious NAEP and  VCPLA Awards that were given away in the last edition. The awards was with full attendance and printers and suppliers networked and celebrated the togetherness.

I present my walk-through pictures of the event:

Driving profitability in labels!

Driving profitability in labels!

 Driving profitability in labels, with embellishments, digital printing & hybrid printing

Self-adhesive or pressure sensitive labels industry in India has grown steadily right from the time of its initial entry into India to be indigenously produced in the mid-1960s when a screen printer manually created the first label. Thereafter, label manufacturing has evolved and completely transformed  technically over the years. Initially, small and slow very narrow web letter presses, 4 or 5inch wide, from the eastern part of the world were used to print with blocks and die-cut labels with flatbed dies in roll form. These presses eventually started going wider in printing width with growth in demand. The need for increased production in 1980s brought in the adoption of rotary flexographic printing presses. However, since the flexo plate technology was just evolving, usage of letterpress block printing was still growing. It was in the new millennium that developments brought in prepress and plate making technologies, made it possible for printers to decrease their dependence on letterpress printing technology and invest in flexo presses that eventually became modular and print widths going wider with increased speeds.

Toward the middle of the first decade of the new millennium, the pop and Mom retail stores, known as Kirana stores catering to consumers, started being replaced by the entry of organized retail outlets and with it, came the increase in demand for labels and packaging. When it was realized the customer’s point of purchase decision to lift the product off the shelf is the driver for sales, brands felt the imperative need for attractive labels and packaging. Different print technologies started being employed and presses with advanced capabilities started being developed and offered. While all this transformation was happening, the label industry in India was all along registering a robust double-digit growth. It was largely accepted fact that even though labels are a very small part of the large packaging industry, it was more profitable. Due to this, the number of label printers kept growing, investments also came in from established offset printing companies. With cheaper label presses coming from China and availability of good affordable machines in India, the label printing capacities have grown exponentially. This increase in capacities, the pandemic, the strikes in Finnish paper mills, the Ukraine war, the re-emergence of Covid in China,  etc. brought the margins in the labels industry under intense  pressure. Raw material prices have since escalated, freight rates, salaries and overheads have increase while competition does not leave room for increase in selling prices. In such a difficult scenario, label converters are looking at options to drive in profitability.

Opinion and comments of label printers across India was sought on how to drive-in better margins in the label production in the given circumstances. Three questions were posed to all, their response is somewhat similar, yet some do have apprehensions about the steps that are suggested whether they will actually drive in margins? However still, a direction on the way forward appears to be an imperative. The  printers in the diverse geographical zones who contributed their views are as follows;

North:

Anuj Bhargava, Kumar Labels NOIDA hereinafter referred to as (AB)

Rajeev Chhatwal, Kwality Offset New Delhi (RC)

West:

Mahendra Shah, Renault Paper, Palghar (MS)

Himanshu Kapur, J K Fine Prints Mumbai (HK)

Priyank Vasa, Unick fix-a-form, Ahmedabad (PV)

East:

Manoj Kochhar, Holoflex Kolkata (MK)

South:Raveendran Selvarajan, Seljegat Sivakasi (RS)

Lakshminarayanan Parthasarthy, Signode India Ltd. (Wintek) Bangalore (LP)

Question: Do you agree that Embellishments, Digital printing & Hybrid printing or converting are important steps to get better prices for labels?

AB: Yes, value added labels do add to margins. However still, the main buyers are few. Startups or premium products cannot add volumes where multiple players offer value additions. 

RC: Embellishments certainly will get you a better price if you have a technical edge over your competition. Just a  different printing process does not get you more price from customers. One needs to decide which process to use to get better return based on machine capabilities .

Hybrid is still not suited for the Indian Market. However good converting and finishing is important for short runs on digital to reduce wastage.

MS: Yes, I agree. With increase of just-in-time orders, shorter runs and demand for innovations,  it is economical and faster to produce with Digital printing. Embellishments complemented with other capabilities, aid improvement in value addition.

HK: More technical the labels are, better is the margin. Unfortunately, large companies expect more for less. The basics of costing has been lost by most label converters. Embellishments also add to costs, but to recover those costs is difficult.

PV: We aim for the best process fit for a job, be it digital, flexo, hybrid or offset. That is the only way to master production cost. Digital embellishment always gives an edge and keeps business secure but does not always guarantee increased profitability, it comes with its own limitations. 

MK: I agree that Embellishments, Digital printing & Hybrid printing or converting are important steps to get better prices for labels. Value addition invariably leads to a better realization. Brand protection elements such as hologram, security inks, security designing also add value.

RS: Not only embellishments, but also innovations along with having capabilities for attending to needs of customers are important. If food and pharma customer needs labels with water-based inks, we need to have those capabilities. If they need booklet labels it becomes an imperative to be able to create them. Every printing process has its own specialty so when you are able to create labels with Hybrid and digital technologies, then of course selling prices are better.

LP: QR codes and AR (Augmented Reality) in labels, connecting consumer to the brand – is what we see as way forward for profitability . Embellishment leads to aesthetics, shelf appeal, increased sale and brand value for better profits to the buyers and converters.

Question: Have you taken any steps in this direction to increase your capabilities?

AB: We are always focused to value added labels. We have capabilities do embellishments like 3-D effects, embossing, textured foiling, screen printing and many other such processes that enhance the aesthetics of product.

RC: We have already invested in converting equipment with finishing and embellishing capabilities like foiling, Screen printing, Lamination etc. Our range of labels includes- Foil stamped/embossed labels, labels with tactile effects, Laminated, 3-D embossed, Variable data and Holographic labels etc.

MS: Since long, our customer profile is such that embellishments and employment of multiple print technologies is an imperative, for this reason we invested in hybrid presses many years back. Currently to achieve just in time capabilities we are investing in digital printing which will also give us additional production time on our main printing presses.

HK: We have always invested to be a capable company, right from inception so have the capacity to do all types of embellishments.

PV: Yes, we have added digital capabilities. Having multiple printing technologies at our disposal, enables us to pick and choose processes that are best suited for a particular job depending on the complexity of decoration required. 

MK: We are constantly trying to scale up our capabilities of adding diverse authentication features and other embellishments such as foiling, registered hologram stamping, variable data printing and finding new materials that are unique.

RS: At Seljegat we always endeavour to stay invested and capable with the latest developments. We have already installed machines with multiple capabilities, and we prefer all inline. We can do embellishments, special varnishes, multilayer labels, digital for variable or personalized labels, embossing, etc. We are always ready to cater to the changing needs of customers, nowadays pharma and food companies are demanding labels to be done with water-based inks or low migration inks, we have immediately empowered ourself suitably to serve them. In today’s time if we cannot deliver that extra, then we get lost in the crowd of intense competition.

LP: We are already having all capabilities and exploring AR in labels as next step towards Brand connect and Brand promotion. 

Question: What in your opinion are factors that can drive in better margins? Please mention steps at given prices of inputs.

AB: Label companies should invest in making labelstocks for captive use, negotiate hard while buying machines and for buying raw materials.

RC: As competition gets aggressive, systems need to be designed to reduce wastages, increase productivity and buy raw material at competitive prices. Making our internal systems strong is the only way out to drive-in better margins.

MS: We started the process of optimizing production costs, long time back. We collected data of all ongoing jobs for past 3 years and calibrated all processes as per the following;

a) We dwell on actual time needed for the job and check if the processes are complying with targeted numbers.

b) If not complying what’s the core reason and if for some reasons not meeting norms,  can solutions be found?

c) Evaluating, if no solution is possible, is the job generating profit for the company? 

d) If not , either get the price increase or discard such jobs to save time for more sustainable jobs.

HK: Rather than controlling the input prices on which we have no control, we should focus on getting better prices from clients. We need to factor-in the basics like label waste that is completely non-recyclable and cannot be salvaged. Label machines are capital intensive we must add the impact of cost of investment in the total price of end product.

PV: To improve profitability;

Freight cost management is an imperative, it can save lot of money.

Process improvements and wastage control is necessary. One should start with small steps like exact web sizes, proper sheet layout, special sizes for volume jobs, ink management and keeping a track of low moving stocks.

Refrain from unhealthy competition.

Learn from your mistakes as a team. Take all complaints seriously. Try implementing simple solutions. 

Update monthly  performance chart of individual operators,  give them incentives for faster turnaround and increased capacity utilization. Take corrective steps to reduce downtime due breakdowns. 

·      MK: Key to improve margins is to provide customised solutions by understanding what the customer needs. We try to incorporate various levels of authentication, embellishments and decoration to tailor solutions that best meet their needs. If a customer cannot afford to pay for the hologram, we focus on enhancing the printed authentication features keeping costs under control, and yet get a price that enhances our profitability while the customer appreciates the value we deliver.

RS:  For driving in better margins, the instant reaction is to buy cheaper but if we have to think of steps at given raw material prices then one has to research internally and implement changes. As a first step we have opted for equipment and steps for faster changeover time between jobs to increase productivity. We have invested in a system for make ready to be completed before one job ends. The changeover time for us has reduced from one and half hour to just thirty minutes. For job set up we were using fresh labelstock but now we use rejected, old and leftover unusable stocks. Next, we are now switching over to LED UV as its operational and lamp replacement cost is lower. New equipment has been ordered and will be installed soon. We plan to install an automatic butt slicer for non-stop production. Reducing wastages is also on our radar and we constantly work on it.

LP: The following steps are necessary to drive in profits;

Watertight operations, control on wastages and minimising set-up waste.

Reducing overhead costs, improving efficiency and OEE (Overall equipment effectiveness).

Propose embellishments to customer making the label more premium to claim better realisation.

Summation:

Price increase is an ongoing process, the impact of inflation is felt every year along with that of other unavoidable circumstances. So, manufacturers need to gradually increase selling prices to maintain a healthy bottom line. Unfortunately, that is an ideal scenario but in actual the selling prices are driven by market dynamics and competition. In the present situation, for the label industry, it is time to look internally and evaluate. Based on the views of the printing fraternity it is largely agreed that embellishments, security features and innovative concepts on labels that enhance the shelf appeal and lead to better sales volumes for brands, can help get better prices. The simpler the label is, more is the competition. As indigenously produced label presses have come within the reach of middle level printers, the competition in that segment has become intense. Moreover, with organized retail and ecommerce becoming the predominant selling systems, need for more decorative labels, IT enabled labels and personalized variably printed labels  with security features has escalated.

Not long-ago setup of label jobs took an hour or more with 2 or 3 persons on each press and at least 100 meters of material being used before final saleable production commenced. With increased automation, advanced automatic registration controls, higher speeds, etc. now a single operator can setup a job in just a few meters in about 15-30 minutes, with increased productivity, less wastages and quick changeovers between jobs by keeping the next jobs ready. Using exact size materials and not generating offcuts is also a necessity. These are changes that add to margins and reduced operational expenses.

Food and pharma safety and health concerns are matters of importance for discerning customers, this, along with statutory rules for toxic or unsafe materials used in converting labels, are to be avoided. There is an increased demand for non-migration and water-based inks because UV inks are considered somewhat hazardous for direct food contact and skin contact applications. Printers need to have such capabilities to supply as demanded by print buyers. Most companies feel that to reduce costs there is need for internal production systems and the workflow to be strengthened or monitored continuously to reduce downtimes at each stage, opt for more automation to reduce manpower and use energy efficient machines, equipment or systems.

Finally, time has come when EPR (Extended producer responsibility) compliance has become mandatory. Sustainability and circular economy are becoming a social responsibility for earth to be a safer planet. Large FMCG companies and brands have already started opting for or expressing preference to buy from certified green companies. It will not be out of place that producing in compliance, may as well add to cost but it may also qualify for better pricing for this good social cause.

Sustainability and circular economy in manufacturing labels

Sustainability and circular economy in manufacturing labels

Sustainability in its simplest terms means, giving back to Mother-Earth or environment, society, or economy, whatever you draw from it. It ultimately delivers a message for us to leave a safer planet with minimum or no depletion of resources, for generations that follow, after meeting your own imperative needs. Let us for example consider just paper. Long years ago, with development of paper, there was  a lot of promotions to increase its usage, but then it was realized that paper production was hugely dependent on wood and increased usage meant deforestation.

It is an accepted fact that forests are very important for a healthy environment and climate. It was on this realization that a lot of emphasis started to be put on avoiding unnecessary paper usage. Even now responsible company emails have a footnote advising not to print unless absolutely necessary. On the other hand, there are statutory directives to paper mills to aid afforestation so as to increase the forest cover and replenish the amount of wood extracted. However still, usage of paper is sustainable when produced with implementation of replenishing the inputs used. Moreover, the paper waste is re-pulpable to again produce paper or paper board aiding circular economy. Production of all manufactured goods and services should avoid or reduce using resources that cannot be replaced and whose depletion will adversely impact the environment. As mentioned above, paper is mostly produced from wood whose extended use in paper production leads to deforestation. For this reason, a lot of manufacturers do a life cycle analysis of products to achieve a level of sustainability.

Brand owners and large label user companies have now started insisting on FSC certified paper usage. Forest Stewardship Council (FSC) is a globally recognized certification system that ensures that the forests are managed sustainably. Products that are manufactured from responsibly harvested forests are identified with the FSC logo, which is considered the “gold standard” of forest certification by major environmental groups.

Circular economy

Circular economy also referred to as circularity and CE, refers to a type of process for  production and consumption, which conforms to reusing, repairing, refurbishing or recycling materials and products. Since CE helps in reducing raw material requirement, carbon footprint and aids sustainability, it has gained popularity. It also helps in conservation of important resources. For an example of CE, milk pouches are made of mono polymers like LDPE for packaging which is easily recycled or reprocessed to again convert to plastic granules that can be remolded into usable plastic products. On the flip side, multi-polymer multi-layered film pouches are not recyclable and end up in landfills impacting environment adversely as they also do not biodegrade.

However, there is work being done to develop processes that will enable these also to be recycled. The government of India is actively formulating policies and promoting projects that will drive the country towards a circular economy system. It is estimated that a circular economy path adopted by India could bring in annual benefits of 40 lakh crores or approximately US$ 624 billion in 2050.

Labels

The material for labelstock consists of many elements and sustainability cannot be in the total laminate, each component must be sustainable and contribute. The self-adhesive label laminate primarily consists of face stock with or without a primer or lamination, pressure sensitive adhesive and siliconized release paper or film. To be sustainable each element must be dwelled upon separately. The life cycle of each of these is different and an analysis needs to be done in-depth to make decisions towards achieving sustainability goals.

Climate change and environmental concerns have now become issues that cannot be ignored and need to be attended to, at national and global levels. With increased statutory government directives to reduce carbon footprint and make sustainability an imperative, manufacturers are under pressure to re-engineer their products and their packaging. Leading brands have committed themselves to sustainability and circular economy to reduce their carbon footprint. Labels also being  a part of packaging must be designed to achieve maximum level of sustainability and circular economy. FMCG brand owners are now preferring packaging solutions that will enable them to achieve decrease in their carbon footprint ensuring recycling of packaging material which is environment friendly. It is thus necessary to dwell on the different components of self-adhesive labels and their diverse usage. In India Avery Dennison has launched a matrix and liner recycling program to aid these needs. The liner collected from converters is sent to a company who repulps the liner mixed with wastepaper to produce tissue for shoe industry or other paper board items. The matrix is converted to briquettes and used as fuel.

Face materials

The label face material is the actual performing part of the label that after application stays with the product during its entire lifecycle. Variety of substrates are used to be the label depending on its performance and aesthetics. These can be papers that are either coated or uncoated, plastic films or other materials. Even paper labels laminated with films are in use. Unlaminated paper is, as such, largely re-pulpable and converted to become recycled paper or paperboard to be reused but here we need to understand that in case of self-adhesive labels, paper alone does not get affixed to the product, it has an adhesive with it. The final label with the adhesive goes on to the product while the waste matrix after die-cutting in converting is waste that often goes to landfills impacting the environment adversely. It can also be shredded and molded as pellets or bricks to be used as fuel.

To that extent we can consider the waste matrix sustainable as it is put to constructive use.  However still, the label that is affixed on the product has to be disposed along with the adhesive and the package it is on. So, we need to use special adhesives for the label to be re-pulpable in case of use on paper based packaging, or removable or washed off for recycling, when applied on reusable glass containers. We dwell on adhesives later in this article. Going backwards label buyers also have started insisting for their vendors to use FSC certified papers. FSC® or Forest Stewardship Council® certified paper is paper that has been harvested in a responsible manner. FSC stands for sustainable sourcing that puts forests and people first.

In case of filmic labels besides adhesive, it is another issue with worldwide movement against use of plastics wherever avoidable. The reason for this is that plastics are largely not biodegradable or non-compostable, so they are not ecofriendly. With EPR becoming mandatory in India, companies are constantly trying to use materials that can be recycled or reused. According to EPR or Extended Producers Responsibility,  which is the responsibility of Producers, Importers and Brand-owners to ensure processing of their plastic packaging waste through recycling, re-use or end of life disposal (such as co-processing/Waste-to-energy/Plastic to-oil/roadmaking/industrial-composting).

The impact is evident from the fact that most companies are shifting towards paper based packaging or even paper based self-adhesive tapes. Many filmic labels are based on mono polymer PE, PP or PET so if they are used on bottles made with same polymer these can be recycled provided the adhesive is compatible. Some companies have been making changes in manufacturing to improve the recyclability of product packaging and look at ways of reducing carbon footprint.  New films, made with 30-50% post-consumer recycled material or made with biobased materials, are offered that aid the circular economy and reduce the use of fossil based packaging while reducing carbon footprint. Some of these films available are fully compostable. Specially designed thinner films that are converted to  be used for highspeed labeling are being preferred as using less material, is a good step toward sustainability.

Adhesives

Often when assessing the sustainability of a packaging, people tend to overlook the impact of adhesives that are an inherent part of the package. An adhesive that may hinder the recyclability or maybe non compostable will become a setback for the efforts to make labels and stickers sustainable. An adhesive must be chosen, such that it will comply with end-of-life process to recycle and reuse or be compostable.

With advancements in technology, adhesives are derived from either natural or synthetic raw materials. A general perception, that adhesives formulated with natural inputs may be sustainable and those made from synthetics are not sustainable, is not true as a rule. Both types of adhesives can be developed and formulated to perform and yet conform to sustainability. It is important to study and select adhesive for labels based on your need. Let us for example consider self-adhesive beer labels in returnable glass bottles. In this case the adhesive should be compostable and easily washable to separate from the glass bottle for the bottle to be washed and reused while the label in the water can also be separated, recycled or dispose without adversely impacting environment. In case of PE bottles with PE labels, the adhesive should be compatible, such that it can be shredded granulated along with the bottle for remolding.  For each application the selection of adhesive is important.

Release liners

Over fifty percent of self-adhesive labelstock used for manufacturing labels or stickers  is generated as waste in converting. This is a known and accepted fact. The waste, more often than not, goes to landfills impacting environment. The release liner that protects the adhesive until the label is dispensed and applied, forms a major part of the waste generated. Since many years companies have been looking at options to either do away with the liner or reducing the waste generated by the liner.

Paper based liners form more than 80% release liners used for self-adhesive labels. The paper-based liners include Glassine, SCK, CCK and Poly coated papers. Linerless labels have been considered and used for some years now but due to growing need for better aesthetics, die-cutting complex shapes and embellishments, they have limited use. To reduce the tonnage of liner waste going to landfills as a sustainability endeavor, there has been talk of reducing the caliper/grammage of liner used but not much headway has been made in this direction.

In India and Europe, glassine is largely used as the preferred release liner and accounts to over 70% of all paper liners used. For long, release papers were not considered recyclable due to the silicone coating which after crosslinking becomes inert. However with development in technology, some companies in Europe and USA  developed a de-siliconization process after which the paper can be processed to reproduce base papers for siliconizing. In the process, siliconized liner is repulped in water containing chemicals to release the silicone and remove the small silicone particles like in the process used for deinking of repulped printed papers. The de-siliconized pulp can then be used to produce new products, such as fine and specialty papers like release liner, label face, writing and printing papers. Thereby achieving circularity.

There has been substantial growth in use of filmic liners that are thinner and can take more labels per roll. The residual filmic liner can be recycled, enabling circularity. To achieve an elevated level of circular economy and sustainability, “CELAB” (Circular Economy for Labels),  was set up by 50 industry-leading companies representing the entire value chain that have come together to create a sustainable pressure sensitive labeling industry by offering solutions and providing education to enable matrix and liner recycling.

It is an ad-hoc coalition empowered to reach across the entire supply chain and leverage the expertise of industry participants to promote a circular economy for self-adhesive label materials. CELAB’s members comprise industry members both large and small, and with both global and regional market presence. It also includes companies up and down the value chain of the matrix and liner industry. According to CELAB, “Like many other grades of film, silicone coated filmic release liners are recycled by regrinding the film into chips/pellets which can then be mixed with ‘virgin’ polymer and re-introduced to a film extrusion line for production of new polymeric film.”

Self-adhesive or pressure sensitive labels industry was at one time considered to be generating waste that was polluting the environment but gradually all-around efforts are driving in sustainability and recyclability. It is a matter of time the processes will evolve and the industry will shed the waste generating tag and grow.

“From Cartons and Commercial Printing to 100% Labels!”

“From Cartons and Commercial Printing to 100% Labels!”

Narinder Chhatwal hailed from a family of traders in Lyallpur, a city which is now in Pakistan after the partition of India in 1947. Lyallpur was named after the founder of the city the then Lieutenant-Governor of the Punjab, Sir James Lyall, for his role in establishing the canal colonisation project. In 1977 the Government of Pakistan changed the name of the city from Lyallpur to Faisalabad (‘City of Faisal’) in honour of King Faisal of Saudi Arabia, who made several financial contributions to Pakistan. Faisalabad is the third-most-populous city in Pakistan after Karachi and Lahore, respectively. It was in the turbulent times of 1947 during the division of India into India and Pakistan, that the Chhatwals migrated to New Delhi. After completing his schooling, Narinder Chhatwal took up a job in the iconic Kwality Restaurant in coveted location, New Delhi’s Connaught Place, a venture set up in 1940 by P L Lamba and his brother-in-law I K Ghei who grew it as a multilocation restaurant chain. Narinder worked there until 1961. There was a strong urge to have his own business, so he set up a unit to produce ice cream cups but as situation warranted then, he left this venture and rejoined Kwality Restaurant yet again in 1964. Despite the stable job, the entrepreneur in him was restless and the urge to set up his own production unit re-surfaced and he finally quit the job permanently to start a printing unit nostalgically named Kwality Carton Manufacturing Company, in a single room rented at Kirti Nagar, New Delhi in 1966-67 using the manually fed treadle letterpress printing machine. He manufactured Ice cream cups, lids, cartons for Ice cream bricks and in fact a host of printed packaging items. In 1971 he could get an allotment for an industrial plot from government at Naraina Industrial Area and he moved the unit to this location where from, they operate to this date.

 
A little over a year after moving into their Naraina factory they bought their first offset printing press, a 712 single colour Dominant, a year later they bought another similar press and followed it up with a 714 Dominant. Falling short of space, the adjoining building was available, so they bought it as they were growing. In 1982-83, expanding further they acquired a two colour Planeta. Once into offset printing, Kwality was in expansion mode, they were adding equipment every alternate year. At this time, they renamed the company as Kwality Offset Printers. In 1986 Narinder Chhatwal’s son Rajeev an 18-year-old had joined business. Rajeev did his initial Schooling at Springdales School Delhi followed with graduation from Delhi University. The post partition Punjabi families who left all that they had, back in what had become Pakistan were hard working and were quick to start from scratch to regain their stature by sheer hard work. The second generation were all following their father’s footsteps and would be helping their parents in the work, spending time after school or college on the shopfloors of their startup units. For them, the shop floors became the training ground, and they learnt the nuances of business hands on. Rajeev was no different, with a  father like Narinder mentoring him and passing on the experience to his son who was a quick learner, he settled down in the business quickly. He however did go for a short training program at Heidelberg Germany. With his joining in, the business accelerated and soon the space in their Naraina factory was again falling short. In 1988, they bought out yet another next-door unit to make room for more production space so now the factory is operating from three adjacent plots. The same year they bought their first four colour offset press a secondhand Roland. Expansion became a routine process. They believed and were convinced that as far as possible it is better to operate from a unified single location in one city. This way the management which was Narinder Chhatwal, and his son Rajeev Chhatwal were not split and would remain a support to each other.

 

 

Until 1995 Kwality offset was producing Cartons, some commercial printed items and wet glue labels. In 1995-96 they decided to become a hundred percent label manufacturing unit which was only wet glue labels. The story of their entry into wet glue labels is interesting. In the early 1990s when the number of breweries started to grow and bottling speeds were on the rise. To label bottles at 250 bottles per minute, the labels needed to be perfectly die punched and stacked to run on highspeed lines. The normal flatbed dies would not work well. Kwality, because of their experience in ice cream cups and lids production were well versed in ram die punching and their workers were well trained in the process. Their manufactured labels ran extremely well on the high-speed labelling machines at breweries and distilleries and soon the word spread of their capabilities. This helped them get the orders from many other breweries and liquor producing companies. It was just a matter of time that they became the largest suppliers of wet glue labels in north India, though they were supplying pan national. It is interesting to note that normally people print and then get into label finishing equipment, here because of their knowledge of finishing the ice cream cup lids by hydraulic ram punching got them into high end big volume label printing. Their first customer for beer labelling was a government owned Haryana breweries at Sonepat making a popular brand of beer those days “Rosy Pelican.” Their success in making the perfectly die-punched wet glue labels also got them their first break in corporate world with orders from the multinational brand owner Nestle.

 

 

It was in the year 2000 when self-adhesive labels were gaining in popularity, the Chhatwals invested in a Mark Andy 2200  narrow web label press and in the following year, they also increased their investment in sheetfed offset by installing a six colour Heidelberg press. In 2002 they installed another sheetfed offset a five colour Roland with UV and online coater. Hereon, expansion became an ongoing process, they added three Mark Andy presses, a Gallus and a Xeikon in 2018 to make their entry into digitally printed labels with an ABG Digicon series 3 finishing and embellishing machine, which also has hot foil stamping , embossing and screen-printing capabilities. These investments enabled them to add multiple security features on labels. Increasing their footprint in flexo they also set up inhouse platemaking with Kodak Flexcel. Rajeev’s father Narinder Chhatwal passed away in 2008 until when, he was still attending business, though the reins had been passed on to his son Rajeev.

 

 

Rajeev’s other siblings include a younger brother who is into real estate and a sister who is a homemaker. His wife Shalini is also a home maker. His son Krish completed his business management from Sydney and joined business at Kwality offset four years ago. Two of those initial years were passed in facing the pandemic and last year in 2021 he got married. Krish’s wife Sanya, an expert in baking, after completing a course from APCA Malaysia, is running her own business, a bakery named Delhi’ce in Gurgaon making specialty cakes. Rajeev’s daughter recently completed her study in architecture and is now pursuing her career as an architect.

 

 

Having put in place a full-fledged team to manage all production, Rajeev, and son Krish personally look after sales and marketing. While Krish looks after all new customers, Rajeev manages and caters to, and successfully retains all old customers. The present spread of business is with three flexo presses, one digital label press Xeikon, Abg digicon, one Roland and one Heidelberg sheet offset press in a shopfloor admeasuring approximately 60,000 square feet. Total workforce is 130 persons all in one location at Naraina Industrial Area New Delhi. With no more space left for expansion at present location, they have bought a 2200 square yard plot at Manesar south of New Delhi for another factory to fuel their further expansion. When asked about future plans, Rajeev expresses that they are not really concerned about just volumes, they are more oriented to implement better and innovative technology and be profitable to grow the bottom line instead of focusing on bigger turnovers. Kwality has been growing at about 10 percent per annum and they are committed to maintain the growth rate. Conscious about the environment they have tied up with approved and certified waste management agencies as also cooperating with Avery Dennison on their waste management endeavours. They even try and source most of their paper materials from FSC certified vendors. Despite the aftereffects of pandemic, the father-son team are committed and firm to keep the expansion and investment in new technologies an ongoing process. Their resolve years ago to give-up cartons and other commercial printing to stay with 100% manufacturing of labels is unique in today’s situation. These days offset printers do integrate forward to produce labels and vice-versa label printers, in an effort to grow turnovers, expand into print packaging. They wish to remain specialty label printers, investing into innovation.

Abhay Datta, a printer’s tryst with machine building

Abhay Datta, a printer’s tryst with machine building

On any given day, 96-year-old S.N. Dutta, Satya Narayan Dutta, the patriarch of Dutta family of Dutta Press New Delhi, can be seen strolling on the shop floors of their printing or machine building units, interacting with workers, and imparting instructions. The man is active and an institution himself in printing. Dutta was born on 15th of August 1926, long years before the partition of India, in a family that hailed from Lahore, then a part of British ruled united India. His father was the head of accounts for Indian railways. Sometime in the 1940s as a young man, he developed an interest in printing so went to a family acquaintance, Kedar Nath Mehta, a master printer in Amritsar for a one-year training in the art of printing. They used to print on Chandler & Price platen presses and supply labels to Punjab based distilleries in Hamira and Khasa. Chandler & Price was founded in 1881 in Cleveland, Ohio and manufactured a series of hand-fed platen jobbing presses, as well as an automatic feeder for these presses.

 

Chandker and Price Machine
Love marriages were rare in those days before the partition of India, however S.N. Dutta during his training days at Kedar Nath Mehta’s facility, developed a liking for Mehta’s daughter and eventually married her. Post partition the Dutta’s moved to their Haveli, a traditional townhouse mansion in Darya Ganj Delhi. The Haveli was a heritage building that had earlier belonged to one Sir Syed Ahmed Khan, one of the Navratans of Mughal King Akbar. It was allotted to Duttas on migration from Lahore to Delhi after partition for a sum of Rupees 4000 only. In 1951 S.N. Dutta started his maiden startup venture “Dutta Press” with a Chandler and Price machine on the ground floor of their Haveli. He bought the printing press for Rupees 1200.00 and did not have the money to put an electric motor on it. So, initially the machine was foot operated with a peddle. As a memento and a reminder of their past, the machine still stands tall on a pedestal in the lobby of their Okhla factory. Thereafter from 1951-1965 Dutta was on the move continuously, he also set up his own typesetting and composing section, then added two more machines, following it up with buying a new Heidelberg GT Platen press for just four thousand Rupees, then in the mid 1970’s a Mercedes Super Cylinder Press from Printer’s House in Faridabad, Nibolo and some more letterpress cylinder machines. Customer base acquired during this period included those from segments like beer, whiskey and lubricants with main customer being Mohan Meakin. S N Dutta has two sons Rakesh and Abhay, as business had grown and the boys were now grown up, it was time to move to the next level of business. In 1980 they moved to a new factory in Okhla and imported their first Heidelberg KORD offset press and Heidelberg TP Foil stamping machine from Germany. Those were tough times of needing import license for all imports, yet firm resolve made them to move on.

 

 

Heidelberg Weisloch Factory
Abhay Datta the younger son of S.N. Dutta, born on 16th August 1961, is an Alumnus of St. Xaviers School Delhi. He was never a serious student but had other technical interests. Barely 16 years old and in school, he started experimenting with making music systems. On finishing school, he along with his friend Joseph George set up their maiden startup venture Systm India to make and sell music systems. Abhay proudly mentions that in a couple of years his company’s turnover was higher than that of Dutta Press. Young boys in business families are prompted to spend time in family production units and Abhay was no exception and whatever exposure he got was by way of his father mentoring him to have a penchant for perfection and zero tolerance in whatever he did. One fine day his father came to him and complained, “you make so much noise testing your music systems, speakers etc., neighbours are irritated . It is not a respectable business. He appealed to Abhay that they needed help in the printing business and that he should wind up this music equipment business and join him in the printing business. Obedient as he was with immense respect for his father, Abhay could not refuse his father’s request. Abhay’s elder brother Rakesh was better in finance and other marketing activities. In just a matter of minutes Abhay decided to hand over the music business to his friend Joseph and moved on to the printing business at Dutta Press. He was sent to Heidelberg training center in Germany for training in print technologies where he spent time in the Wiesloch factory understanding mechanics and engineering of offset presses. It was an eye-opening experience for him. In India we did not have CNC machines, no auto cad computers, all the planning was done manually on huge drafting boards. It was there in Germany that he gathered an eye for perfection, low tolerances, fine finishing, good appearance and machine safety norms. This was as his father had mentored him to be a zero-tolerance person.

 

 

UV Coating Machine
Once back in the Okhla factory Abhay had to begin at the lowest rung of the ladder. He was required to clean up the machines, sweep the floor, take care of staff, serve them tea and support them in small errands besides operating all the machines personally. He learnt to run all the machines like an operator, make negatives/positives and offset plates and foil stamping blocks himself. Those were days when there were no PS plates, so he learnt all the chemistries hands on. Graining offset plates, putting sand, marbles etc. in graining machines, he did all that himself. He was a total worker like any laborer in the factory doing all kinds of jobs that included printing varnishing cutting packing and dispatch. The experience has rubbed on so well on him that even today on the shop floor in hot and humid conditions with perspiration trickling down his torso he enjoys remaining amongst his workforces. He is a hardcore technical and shopfloor production-oriented person while brother Rakesh manages the white-collar part of management. With Abhay’s penchant for perfection, he proudly mentions that we made quality, such that print buyers would come looking for them. Since they were supplying to breweries and distilleries, they came across a challenge; solvent base varnishes on labels scuffed and needed to be replaced with Water based varnishes, but these would not work on existing hand fed varnishing machines produced locally due to slow drying. Abhay was given a task by his father to make a machine that could coat aqueous varnishes at high speeds. He developed an automatic machine with the help of Sanjay Gupta of Ronald Machinery and added an anilox roll with a motor and hot air dryer to do the varnish. It worked and that was when his tryst with machine building commenced. Later he started manufacturing fully automated high-speed machines to do aqueous and UV coating with anilox rollers and chamber doctor blade systems.

 

 

Abhay Datta on Shop Floor
 

 

After that there was no looking back in machine developments. Abhay was young, success encouraged him to research, experiment and develop more from a shed in the driveway of their Okhla factory, it has been a long journey with lot of hurdles. He then started converting hot stamping machine for own use and sales. Since in earlier days they had bought a Heidelberg hot stamping machine, from experience gained, Abhay could convert die cutting machines and the Chandler and Price machines into hot stamping machines. When stamping foil suppliers became aware of his capabilities to make hot stamping machines, he became an accredited suppliers to many companies who indulged in hot stamping. In 1992 he successfully started making UV coaters and till 2016 they have supplied over 250 offline UV coating machines in India and Abroad.

 

 

During his 1995 visit to Drupa, he was fascinated by an Aquaflex label press printing Smirnoff Vodka labels. Unlike the sheet fed converting, the press was unwinding, printing, embellishing, laminating, die-cutting and delivering finished labels at the end of line in a single pass. Abhay was convinced that this is the future. Those days there was no WhatsApp where he could take videos and upload to inform his family about the equipment. Wanting his father and brother to also look at the machine before deciding, he made a trunk call, described the machine and requested them to come and see. Three days later both his father and brother flew into Germany, they saw and fell in love with the machine. They became friends with the founder of Aquaflex, signed the deal to buy a press and also became the sole selling agents in India. They opted for an eight colour press with rotary hot foil stamping. It was a bold decision as rotary tooling for hot foiling was very expensive, cold foil was not there that time and most of their production for liquor labels needed foiling. In their factory they already had 20 Heidelberg hot foil machines running, they used to buy used Heidelberg platen machines and convert them into hot foil stamping machines by retrofitting, all done by Abhay himself. The Aquaflex ordered by them was displayed at Labelexpo Singapore in 1996 and then shipped to India for Dutta Press to start printing labels on a narrow web press. Till the end of the millennium 1999 they were only printing wet glue labels on this machine. Pressure sensitive adhesive (PSA) labels production commenced only in the new millennium in 2000, they kept adding Aquaflex presses in regularity.

 

 

Ultraflex Label Press
Between 1996 and 2003 as agents, they sold nine machines to customers like PPL, ITC, Modi Federal, Sai Packaging and others. They added four more press at Dutta Press. In 2001 Aqua flex got sold to Chromos USA . At this time when he was under pressure to offer a press to his customers, he met a software engineer who suggested the name of Shanti Pal Ahuja of Multitec and once the two met, they instantly decided to get together to build label presses. Abhay invited Ahuja to his facility and have a look at the Aquaflex label presses and to do reverse engineering of the press. A complete unit was removed from the Aquaflex and sent to Multitec facility in Faridabad. It was completely meticulously redrawn and the first Ultraflex machine was developed and sold to Nishi Labels in Ahmedabad and the second machine was exhibited at Nehru Centre in the first “India Labels show” which later became Labelexpo India. That machine got sold on the very first day of the show to Khosro Moradi, of Farah Banfash Manufacturing Company, Iran. Few years down, having sold over a dozen presses, their partnership fell apart and Multitec renamed their press as Ecoflex and Abhay Datta retained the name Ultraflex that he would build himself one day. Until such time for their own label manufacturing they invested in Bobst label presses

 

 

CNC Machines at UV Graphics
Passionate about making machinery himself, in 2017 after they bought their 3rd Bobst M5 press, Abhay visited Florence and was inspired to build his own flexo press. On return from Florence in September 2017, he dug deep into the Flexo Machines and studied other equipment that would enable him to build a narrow web label press. Keeping cost down and not compromising in automation he started planning a machine with zero waste and instant make ready. He launched his first Ultra flex made in his company UV Graphics. 

 

 

 

 

Ultraflex Plate Mounter
He insists that for a perfect and quick make ready, “a communication between the plate mounter and the machine is imperative.” Abhay also started making plate mounters. He asserts that with plates mounted on his plate mounters, the first meter of print which rolls out will be 99% in true register. This is his creativity. His machines and plate mounters are designed as perfectly complementary and compatible equipment  so as to make life easy for the machine operator. He claims that in 3-4 minutes you can perfectly mount an eight colour job on his plate mounter and have the machine running in full register within 3-5 meters. That says Abhay is our USP. Ultraflex machines offered by him are of international quality, fully servo driven with auto register control, it is value for money and affordable. Ever since, Abhay has already installed thirty-eight presses in India and abroad with the latest ten color machine being shipped to a prestigious customer in USA. This will be his first installation in North America and fifth machine being sold overseas.

 

 

 

Abhay has two sons Anuj and Akshay and a daughter Aallia. Both sons run the PSA labels division of Dutta Press while brother Rakesh manages the wet glue label business from Okhla. All family members are in business together as a joint family. UV Graphics and Dutta Press operate out of 66000 square feet factory in Noida and an 18000 square feet facility in Okhla with seven flexo presses in Okhla and six flexo presses in Noida. With a total of 280 employees, Abhay aspires that if God and Kismet helps UV Graphic will be a leading global supplier of diverse label equipment in 5 years. He proudly says, “we produce from nail to the hammer. In UV graphics we produce our own UV Systems, Plate mounters, Core cutting machines, Label presses, Slitter Rewinders, Semi Rotary Digital Finishing, Print Cylinders, Magnet Cylinder, Sheeting Cylinders, Hot Foiling Stamping Equipment, Screen Printing and almost everything that is needed for flexographic label printing and converting. We also make wide format Roll to Roll Hot Foil Stamping Machines for the tobacco industry.

 

The way Abhay Dutta is moving it will not be long before he achieves what he aspires.

Sigma Middle East labels- Rising from humble beginnings.

Sigma Middle East labels- Rising from humble beginnings.

 

UAE or the United Arab Emirates consists of seven independent city-states or emirates: Abu Dhabi, Dubai, Sharjah, Umm al-Quwain, Fujairah, Ajman, and Ras-al-Khaimah. Total population of all the emirates of UAE put together is much less than that of New Delhi India at 11.42 million with only 20% Emiratis and rest are expats making it the highest percentage  of  expatriates in any country in the world. The Indian expatriate population at 28% is the largest group in UAE. It is surprising that there is a substantial number of label printing companies there with more printers joining in year after year. In the start of the new Millennium, one could count the total number of label printing companies to around 10 which has now grown to over 40. Even though leading printers speak of intense competition and depleting margins yet there is a steady news of expansions and new companies joining the bandwagon of label printers. Obviously, it is not the local demand but due the business environment, conditions and facilities, the printing companies reach out to customers not only in the Middle East but also to Africa, Europe, and USA. It is a global hub from where they produce and export. It is normal to hear label printers in the region expressing difficulties due to a small market and intense competition, in such a situation it is heartwarming to see someone who comes from a fragile financial status, jumping into label printing and starting to register smart growth. One such person is Jagannath Wagle who endeavored to take the risk of setting up from virtually nothing, his maiden label venture, Sigma Middle East Labels that has started rising from humble beginnings.

 

 

 

 

Jagannath Wagle

It is rare to find humble people these days. Humility is putting pride behind, staying grounded to reality, have faith in oneself and learning from one’s modest beginnings to continuously move ahead with firm resolve and keep evolving. That is how Jagannath Wagle talks with respect and nostalgia about his humble background and times when he was growing up. this: As if living with his parents in a one 300 square feet room flat in Mumbai’s western suburb Nala Sopara along with two brothers was not crowded enough, to help the son of a family friend in village, his mother brought the boy to Mumbai to stay with them.” Jagannath’s father, an auditor with the government of India’s audit department had to manage within the meagre means to support a family of 6 people living in one room. However still they managed to impart the right education to all the children. Jagannath’s mother was a homemaker in true spirit, managing the household and the children by taking home tuitions, he reminisces fondly about her being an excellent cook.

 

 

Jagannath Wagle studied up to class 10th in Little flower English school in Nala Sopara followed by joining father Agnel technical college in 1992. Unfortunately, due to Mumbai riots in 1992 he could not attend college, had to drop a year, and later joined an institute in Vasai to complete the secondary school education. Later he wished to join an engineering college but could not afford the capitation fee demanded by institutes those days so as an alternative he studied to graduate with B.Sc. degree in Physics from Mumbai University in 1998. Due to the financial stress, a relative in Delhi suggested for him to join the Coast Guard but his mother did not relent as she wanted him to study further. He finally went on to get a B.Sc. (tech) degree that was equivalent to an engineering degree. Thereafter he started making applications for job in various organisations and also to start with, he accepted a job with a relatively small company TechGyan at a meagre salary of Rs.4000.00 per month (Approximately 55 dollars). He had a lot of interest in computers so had acquired knowledge about them and as a business to augment his earnings he started assembling computers for customers on job work basis charging Rs. 2000.00 per computer. He had already catered to almost 50 customers. At this time, he started getting interview calls from companies like HDFC, Wipro and Reliance. He was excited that he got selected in Reliance at a salary of Rs.18000. per month to start with. It is strange and a matter of kismet as to how life leads you to your eventual Karma Bhoomi, the land where one eventually works or performs his life’s deeds, this is as expressed in Indian literature. Before Jagannath could join Reliance, his family got a call from his mother’s brother in Dubai who had been tricked by someone to invest in a label manufacturing unit, knowing nothing about labels and he needed help. He requested the family to send Jagannath to Dubai.

 

 

Ajman
Like any young man Jagannath also had aspired to work in distant lands like Europe and USA but for the Dubai offer by his uncle, he was hesitant as he knew nothing about labels, his knowledge was limited to computers and engineering. His mother impressed upon him to go to Dubai and support her brother who needed help and who else he could rely upon except family at this time.  The decision was made and on 28 January 2004 Jagannath Wagle landed in UAE which everyone impulsively refers to as Dubai due to its being recognized as the face of UAE. He started to work with his uncle in Ajman, as a salesman on a salary of 1500 Dirhams per month. Though he started as salesman, but his job profile eventually became all in one, heading the label business with a team of only 3 persons just like a startup entrepreneur. Jagannath knew that with UAE having one of the highest per capita income, it would be expensive and difficult to manage in the income promised and more difficult if he got married. To make success of his career he plunged head on into the business he had no knowledge about. Customers and suppliers became his teacher and taught him all about plates, cylinders, color management etc. he was a fast learner. A business that was 10000 Dirhams per month when he joined and his uncle was pumping in money each month to sustain expenses, became 100,000 per month  in just a year’s time, all this with just one two color small tacky boy press. Any label printer will understand the  effort that must have gone into achieving this.

 

 

 

Pooja Wagle
In 2005 Jagannath convinced his uncle that to remain in business they needed another machine. A used 1980 model 7” 3color Mark Andy 830 was acquired. In today’s time of advanced servo driven modular presses that equipment sounds irrelevant yet by 2007 he was able to reach a sale of 350,000 Dirhams per month by working 24 hours every day, the Tacky boy press became redundant. Jagannath’s salary was enhanced to 3500 and he got married to Pooja from Bohisar in Mumbai. Pooja also came from a very humble background, the father having passed away, her mother taught children of poverty-stricken people. She was working as a credit card salesperson with ICICI bank. They came in contact through a matrimonial website and the marriage was arranged by parents with the couple having never met each other. Once married the couple faced financial stress and there was need to move up in life.

 

 

 

 

Part of Sigma old factory shed
There was no scope for further expansion with the existing Mark Andy 830 press, discontent crept in, Jagannath contemplated on starting on his own or returning to India, but his wife Pooja put her foot down that there was no way she will go back to India and bring up her children there. Meanwhile Jagannath’s cousin had joined the label business and took over the management. Jagannath decided to initially start his own trading business of making non adhesive liners for cores. Having no money to start manufacturing himself he started out sourcing converting also from his uncle’s company for whom he was working. He was so respectful toward his uncle because of whom he was in Dubai and had indulged in learning the label business, that he made sure not to touch any customer who was buying from them. He even kept working simultaneously with uncle during the day and after office hours for his trading business because he wanted to let his cousin to complete his MBA before he left that business completely. Once free Jagannath decided to get full-fledged into labels but making sure he never touched his uncle’s customers. He started getting his jobs done from a company called German labels and as luck would have it sometime later the owner of that company decided to quit business and sell the machine.

 

 

 

Old factory shed
Jagannath wished to buy that press but did not have the funds, so he requested the owner to accept instalments, fortunately as he was destined, the owner agreed to handover the press with 50% down payment and 50% in 6 months. Now the 50% down payment was also not there but a determined Jagannath Wagle refused to give in. In due course of time his two brothers and the friend who lived with him in Nala Sopara had all moved to Dubai and were in good jobs. They all came to rescue and pooled in money to help him buy the Mark Andy. The trade license he took in 2009 was converted to a manufacturing license in 2010. So, in January 2010 Sigma Middle East Labels Industries LLC  started their maiden venture operating with a 250mm preowned Mark Andy 830 press in an 1100 square ft shed in Ajman with just one operator and a helper. Hard work and sheer perseverance produced good results and at this time a difficult situation cropped up. The only operator he had met with an accident and in emergency had to go to India. It was during the Eid period when business is at a peak in UAE, not being the one to be left behind, Jagannath himself operated the printing machine for the next three months. When a container of stocks arrived, he and his only helper would unload and moved goods into the shed and stack them. As at that moment he could not afford help and this incident will always keep him grounded to reality. Watching him make the gigantic offer many suppliers came forward to support him. He is extremely appreciative of Ajay Mehta of SMI Coated products for his support in supplying material on credit to his start-up venture.

 

 

 

Multitec
In 2012 when his sales from just one press reached 150,000 to 200,000 Dirhams per month, it was time for Sigma to move on to the next level and acquire another bigger press, he wished to install a European brand, but paucity of funds made him decide on an eight color all UV Multitec 330mm label press which was installed in 2013. It was his first modular press and was a big jump for Jagannath. Even though he lost some money initially as his costing was not right but soon, he took corrective steps towards growth, “This was my biggest learning curve” says Jagannath. 

 

 

Bobst at New Premises
Two years down the line in 2015 a jubilant Jagannath fulfilled his dream of acquiring a European label press, a Gidue MX370 , 8 color all UV, 1 die station, delam-relam, cold foil and lamination was installed along with and some more additional equipment, also adding more shopfloor space. The fast unplanned expansion led to problems in cash flow and in 2016 Sigma ran into financial stress and troubles. Payments to suppliers were delayed and supplies became restricted. A person having risen from grass roots and not the one to give up, Jagannath kept constant touch with his vendors assuring them safety of their investment and in the meanwhile putting in enhanced efforts to nurture his company to good health. By 2017, recovery had started. Sigma moving ahead acquired yet another Gidue like the one they had. 

 

 

Brotech Finishing
Here on, a more professional approach was put in place, targets planned and achieved, more ancillary equipment including a Chinese press 5 colors with UV and hot air in 2019 to print the liners for cores was added and the second Gidue like the one bought before was bought. Yet again mentions Jagannath that SMI was there to support him, he remains indebted to them. However, learning from past experiences, he sold the Multitec press so that he did not run into financial stress again. The one 1100 square feet shed had multiplied to become 4 sheds and continued growth had become a reality at Sigma. The first used Mark Andy 830 that he had, was given to a friend in Oman at low price to help him.

 

 

 

New office

 

 

 

 

 

In 2020 things became comfortable, Sigma moved from the four 1100 square feet sheds to a plush well planned 12000 square foot facility with well-furnished and equipped offices. 

 

 

 

Going Digital with Konica Minolta

 

 

 

 

 

 

They invested 5 million Dirhams adding a Konica Minolta, foiling equipment and Esko and Asahi plate making system. 

 

 

 

 

Reception of new premises

 

In early this year 2021 Jagannath decided that his company had to upgrade to latest equipment to be more efficient in production, he sold the first Gidue he had bought and replaced it with a brand new fully loaded Gidue M5. Jagannath has finally put Sigma on its road to success and bigger business, he attributes the his journey so far to the inspiration that he got from a Indian picture “Guru” based on the life of Dhirubhai Ambani the founder of Reliance Industries Ltd. He still quotes the dialogue from that film, “If I am doing well why not for myself ?”. 

 

 

 

 

The credit for this amazing journey largely goes to the woman behind Jagannath, his wife Pooja who solidly supported him right through, besides bringing up their only daughter. Pooja is a partner in the company holding the purse strings as the financial controller. No business succeeds without a good team Jagannath and Pooja carefully built their team as a family and took only people from grassroot levels and trained them, two of their teammates had joined as labour/helpers and now work as business development executive bringing in half a million Dirham business each. During their struggling days, Jagannath’s brother in law Kishor Vedpathak quit his job in Mumbai to come and support him, he now looks after Sigma as admin manager. Looking back, he reminisces that his first big break was when he got a big order for 100,000 price marking rolls from Centre Point Chain retail stores. He plans to enhance capacity again later this year with yet another flexo press plus another digital press. Up from just two employees when he started on his own, he now works with 55 employees including four designers inhouse, Sigma has registered a sale of 25 million Dirhams last year growing 30% in a pandemic year!

 

 

 

Jagannath in his new office


Deep in thought and with a smile he mentions that he wishes to be if not the biggest, he will try to be one of the biggest label printers in UAE in 5years time. He is confident that he will continue to lead Sigma Middle East Labels to keep rising to higher levels.

Life in Labels-Yesterday, Today and Tomorrow!

Life in Labels-Yesterday, Today and Tomorrow!

A resilient label industry that was reeling under the adverse impact of lockdown due to Covid-19 is now clawing its way back to normalcy despite facing a highly stressful financial situation that has left them staring at a massive gap in cashflow and loss of production. Customer demand is low as regards retail, with malls still not opening to full strength and consumers restricted to their homes, buying only essential items of use. A sudden spurt in requirement of sanitizers and pharma products has given a fillip to the label requirement but one is left wondering how long this will stay and with increasing number of printers offering similar products, the price of labels for this segment will also soon become intensely competitive and non-remunerative with no value addition needed as a necessity. The silver lining is that the industry at large is confident to bounce back to the pre-Covid levels, but this may take a few months to a year or more. Underlying threat of the virus not dying down continues to haunt the industry and it is time to look back evaluate the present and foresee or plan for a consistent future.

Successful LMAI digital print technologies event in south India

Successful LMAI digital print technologies event in south India

The narrow web label industry is a smaller segment of the larger diverse printing and packaging industry. It remains in focus for being the face of all products and an imperative identity providing part of any package. It is estimated by many that the Printing industry in India is growing at over 12% per annum. Some segments get slower and there are others like packaging are growing at a faster pace of 17% to compensate the shortfall by registering better growth. The label industry has been growing in a very wide band between 10 and 25%, the growth has always been in double digits. While Offset is the largest segment of the printing technologies employed yet the past 2-3 decades have seen growth in adoption of other printing processes like flexography, Roto

In recent times the convenience of “just in time computer to print capabilities” has resulted in adoption of digital printing by many printers such that the segment is registering robust growth of 30%. The narrow web label industry that is largely employing flexographic printing has been conservative and hesitant in adopting digital printing for labels because of higher investment in capital equipment, expensive inks and costly printheads needing replacements resulting in costlier labels in comparison to those produced on their existing equipment. The return on investment appeared to be unattractive. It was just a matter of time that the growth of digital printing of labels in India would start to attract investment. Finat, the European label Association with global membership had reported a couple of years ago that European investments in digital presses for labels in a year had exceeded that in flexo presses. We now see an evident interest and indulgence in this digital label printing technology by Indian printers as well.

Recognising the need for knowledge and understanding  digital printing technologies since label printing and converting is in an evolutionary phase of adopting digital printing, while still growing with analogue, LMAI-The Label Manufacturers Association of India organized a program titled “DIGITAL PRINTING IN LABELS – THE WAY FORWARD” for the benefit of its members only. The program took place at ITC Welcome Hotel, Chennai on the 20th of December 2019. Unlike the other printing processes digital printing has largely four different tangents; Dry toner printing, Liquid toner printing, UV Inkjet printing and water-based Inkjet printing. To deliver the knowledge, leading companies came forward to sponsor the event as also to make very interesting presentations. The following speakers from their respective sponsoring companies made presentations;
 
  • Dry Toner Digital: Xeikon. Presenter; Vikram Saxena, Sales General Manager Xeikon India (Part of Flint Group)
  •   Liquid Toner Digital: HP. Presenter; Ashok Pahwa, Sales Manager-Indigo & Inkjet Solutions (HP India Sales Pvt Ltd).
  •   UV Inkjet Digital: Domino. Presenter- Ajay RaoRane, Asst. Vice President-Digital Printing Solutions. at Domino Printech India LLP
  •   Water Based Digital: Astronova Inc. Presenter-Goutham Reddy, Regional Sales Manager
  • Non-speaking support Sponsors: Avery Dennison and Durst Phototechnik AG
After welcoming more than eighty delegates present and after felicitating the sponsors, LMAI Secretary Rajesh Nema handed over the moderation to Harveer Sahni member LMAI Board of Directors.
 

Sahni updated the audience on the journey traversed by the label printing industry in India. Starting from the first self-adhesive label made by screen printing process in 1965, he covered many landmarks in the evolution that included the first flat-bed very narrow web Japanese label presses to produce labels in roll form in 1972, rotary label converting in 1982, flexographic label printing in 1993, adoption and development of UV flexo from 1997 onwards, setting up of LMAI in 2002 and the first installation of digital label presses toward end of the decade of 2000.

All the speakers gave important insights in the technologies offered by them and emphasized the need and importance of short runs, personalization and variable data on labels and for that how Digital Printing capabilities are fast becoming a necessity.

Goutham Reddy from Astronova explained the cost effectiveness of water-based process and also dwelled on their offering equipment to print on finished packages, 

Ajay Rao Rane of Domino highlighted the strength of UV inkjet and achieving a higher colour gamut besides printing opaque UV white that is needed for transparent films, 

Ashok Pahwa demonstrated the success they achieved in personalization of leading brand of beverages giving another dimension to retail marketing of fast moving consumer products and finally 

Vikram Saxena of Xeikon informed that digital printing was picking up pace with over 32 high-end installations reported in India. He further informed the benefits of dry toner digital printing technology and that it did not require any precoated media.

It was encouraging to note that despite the event being organized in South India many printers travelled from all over India to attend and to learn the nuance of this emerging technology. Some of the printers seen at the event included Gee Kay-Bangalore, Seljeget-Sivakasi, Fairfix-Tirupur, ITC-Chennai, Manipal Technologies-Chennai, Prakash Labels-Noida, Kwality Offset-New Delhi, Pragati Graphics-Indore, Speclabel-Kolkata, Total Print-Mumbai and Zodiac Graphics-Hyderabad.

LMAI founder members Raveendran of Seljegat, Sandeep Zaveri of Total Print, LMAI founder promoter Amit Sheth and Board member Ajay Mehta of SMI were present at this important industry event.

An interactive question answer session was followed by a vote of thanks by Rajeev Chhatwal Vice President of LMAI. The evening ended with networking cocktails and dinner.

Selecting Digital Label Printing technology

Selecting Digital Label Printing technology

“Change is the only constant in life.” This is an age old saying and it is so true! As we look back in time that has gone by, the evolution in technologies that impact our life is amazing and for the new generations it is difficult to imagine the path traversed by elders.

For example, look at the development in telephony and communications; there was a time when, to get a telephone we had to make a lengthy application with documents plus a hefty deposit and then wait for 3 years to get a telephone. For dialing national or international numbers one had to book a call and experience endless wait to be connected for a 3 minute call. Those who did not have telephone connections had to visit a post office to call relatives in other cities, book a call and wait for their turn until the operator tried to connect them for a call that they had to pre-declare the duration as 3 minutes or 6 minutes. Mobiles have transformed life and we have instant voice and video communication capabilities 24X7 with multiple phones in our pockets. The mobile is perhaps the most impactful technology experienced by us in life so far. In a somewhat similar manner, printing technologies have evolved over hundreds of years to bring changes enabling perfection and colourful meaning to all printed products. A technology that began with carving stone blocks, apply colours and transferring images, evolved to using wooden blocks, metal type sets, letterpress printing, screen Printing to offset printing, a technology that was widely adopted and spread across the world as the most preferred print process. Also evolved flexographic and rotogravure printing. All these technologies had a costly pre-press and make-ready process as also the cost of artworks, plates, print cylinders, etc.

The 1970s saw the beginning of an era that would continue to impact the print industry in a totally different tangent, the digital printing! The technology enabled printing with a command from a computer with press of a button without much of processes that were needed in conventional printing.

It is so much like the changes in mobile phone technology coming about. By 1993 the digital printing technology developed such that the first commercial digital printing press named “Indigo” was produced by Benny Landa in his company with the same name. This transformed the printing world; one could now print personalized short run jobs straight from computer. In 2000-2001, the company Indigo was acquired by Hewlett Packard (HP) and at the time of acquisition Landa had said, “Our vision has always been to lead the printing industry into the digital era and to see Indigo technology pervade the commercial market. Now, a part of HP, that goal is in sight.” Rightly so, the market of digital printing has been registering robust growth. Digital printing technology has been developed by various press manufacturers and is being widely adopted with innovative indulgence.  Label manufacturing is an integral part of print and has also been witnessing growth both in terms of total market as well as in Digital printing of labels. The global market for label printing has been growing steadily in recent times, valuing at $36.98 billion in 2017. As per Smithers Pira the total market of labels is likely to cross 49.9 Billion USD by 2024. According to Finat; 2017 was the first year that, with nearly 300 digital press installations, the volume of newly added digital label presses surpassed that of new conventional label press installed volumes.

While label printers in the western world have been early investors in digital label printing presses yet the Indian printers have been skeptical about the need for this investment in the Indian label production scenario.

The different types of technologies available leave the printers in a confusion as to what is the most appropriate technology that they should invest in. Unlike other conventional printing processes evolution of digital printing has moved into different technical ways of achieving the same goal which is computer to print.
Largely available technologies offered by various manufacturers of digital equipment are as follows;
1.       Dry toner based

2.       Liquid toner based

3.       Inkjet

4.       UV Inkjet

While looking at the selection of digital print process one also needs to decide the finishing of the labels whether they wish to do this inline or offline. Every different short run job maybe of varying shape requiring frequent stops and change of cutting dies.

This substantially reduces press running time and impacts profitability adversely. In such a case it is advisable to finish the labels offline, one offline equipment can free up printing time of multiple presses. Laser die cutting is another option whereby it can handle multiple and frequent job changes without the need for additional dies and machine stoppages, but this calls for a much higher investment in the finishing equipment.  Additionally, one needs to decide with digital, what dpi resolution to go for; does the work need a white ink in one of the printing heads; does the press have an extended color gamut. Press running speeds of all the digital label press technologies vary quite considerably. The printing speed with many short-run job changes is also an important factor for consideration.
Dry Toner based process:

This process is an evolution of the earliest photocopying process known as Xerography invented by Chester Carlson founder of Xerox and converted as Laser printer by Gary Keith Starkweather in 1970s which transformed to digital printing with laser printers also called electrostatic digital printing as we have seen in our offices.

In a laser printer a laser beam runs over an electrically charged drum preparing an electrical image carrying charged areas.  The drum is a cylinder coated with a material that becomes conductive when exposed to light or laser beam. Areas that are not exposed have a high resistance which allows these areas to hold the electrostatic charge necessary for the process. The image then collects the toner and transfers the image to a paper or substrate that is then heated to fuse the image on to it. In traditional xerography the image is formed by reflecting light off an existing document onto the exposed drum which then picks up the toner and transfers the image. Dry toners consist of pigments embedded inside polymer beads. The fusing phase of the electrophotographic process melts the polymer beads to the surface of the paper. These can print on both coated and noncoated papers. Image quality is a complex issue, determined by a combination of hardware, software, consumables and processes. Dry toner is not absorbed by the substrate, it always achieves an optimal optical density as all the ink transferred is adhering on surface. The particle size of the toner has been reduced over the years to achieve fine print results and most equipment are offering prints of 1200 DPI for solids and blends with good color depth and subtle contrasts, ideal to reproduce vibrant images.
Major brands offering dry toner based digital label presses are Xeikon and Konica Minolta.
Liquid Toner based process

Liquid toners also use pigments in polymer beads, but they are dispersed in oil that evaporates during fusing process. Liquid toners are used in digital presses that are typically used for commercial printing on a wide range of coated papers.

Benny Landa an Israeli inventor mentioned above, having to his credit 800 patents produced the first Indigo digital printing press in the early 1990s using liquid toners in a process that was called liquid electrophotography or LEP in his company established in 1977. Landa came to be known as the father of digital printing. The liquid toner used by HP came to be known as ElectroInk, that combines the advantages of electronic printing with the qualities of liquid ink. ElectroInk contains charged pigmented particles in a liquid carrier. The image is created with electrophotographic process on the drum directly from digital data, avoiding the use of any analogue intermediate media. It starts with digitally created pages or print elements containing text, layouts or images. HP Indigo uses a blanket in between to transfer ink from the drum to media. The blanket is heated, melting and blending the ElectroInk particles into a smooth film. This produces an image that is completely defined on the blanket and transferred to the substrate by direct contact. For this reason, it is also referred to as offset digital printing.

Major brand using liquid toner based digital printing process: HP
Inkjet Printing:

Inkjet printing is the oldest of technologies in non-contact printing evolving into digital colour printing commercially. Existing together there are two main inkjet technologies i.e. Continuous Inkjet (CIJ) and drop-on-demand (DOD).

The CIJ method has been in use for ages in which a high-pressure pump directs liquid ink from a reservoir through a gun body and a microscopic nozzle, creating a continuous stream of ink droplets. These droplets are subjected to a varying electrostatic field and then these charged droplets pass through another electrostatic field to deflect them and form characters. The process can be understood by the image reproduced from Wikipedia. The Drop-on-demand (DOD) is divided into thermal DOD and piezoelectric DOD. Most commercial printers use the DOD to print. The large format ones use solvent or water-based inks depending on the equipment and the product. The inks used in digital inkjet label printing presses are water based and formulated with either dyes or pigments. Aqueous inks provide the broadest color gamut and most vivid colors. The water-based inks are inexpensive and may ultimately spell out as the lowest cost print, but some substrates may require specialized coatings as there is an imperative need for the ink droplet to sink straight in and not to smudge or smear. With growing volumes, increased environmental and consumer friendly nature of inks the coated stock prices are likely to become largely affordable making this technology to watch as wider acceptance is envisaged. Such inkjet printers can achieve high resolution of 1600 DPI. Since the start of a new millennium another water-based inkjet technology called Memjet has been evolving. Memjet is used in high speed, full colour printers to give a high-quality print at a very low cost. It uses a fixed print head unlike conventional inkjet printers where the cartridges or head moves back and forth during printing. The Memjet print head is fixed and is of the width of the material it’s printing on enabling edge to edge printing. This way it’s only the material that moves underneath the head as it’s printed.
Major brands using water based digital inkjet printing: Trojan from Astronova, Afina, Colordyne
UV Inkjet Printing

UV inkjet Digital printing is an extension of the inkjet printing that uses ultra-violet light to dry or cure ink. The inks consist mainly of acrylic monomers together with a photo initiator and after printing when exposed to strong UV lamps or in case of specially formulated inks to LED-UV light, the ink is cured by crosslinking.

The ink due to this chemical reaction becomes instantly dried leading to increased printing speeds. The curing process with high power UV exposure for short periods of time (microseconds) allows printing on thermally sensitive substrates like BOPP and PE. Since the ink sits on top of the substrates and neither is dried by evaporation nor by absorption resulting a robust image on a wide range of uncoated substrates. It is the fastest growing sector of digital inkjet printing and more sustainable than conventional printing.
Major brand using digital UV inkjet printing: Canon, Domino, Durst, Epson, Screen, Xeikon

Selecting digital printing equipment for label printing is a complex task depending on the printer’s customer portfolio. It varies on many parameters, like the equipment price, ink price, media cost, media to be printed, consumables cost, speed of machine, resolution required, space and finishing required.

Time is not far when printers will invest in multiple technologies to attain the best of each process and to service a wide array of customers. However to start with the print on demand feature is so very attractive and for short runs it seems to be becoming an absolute necessary at least in case of established printers whose large investments in high end flexo or combination presses gets held up doing shorter runs and taking away valuable production time. Since short run demands from brand owners continue to swell along with need for variable data, it becomes necessary to opt for an offline finishing equipment which does not slow down their printing capabilities.

Most of the leading label press manufacturers have started offering Hybrid machines with combination of Digital and flexo printing capabilities along with decorating and finishing inline. It is not a simple decision to opt for the hybrids.

As mentioned earlier here, it all depends on the portfolio and requirements of individual label printers. It is interesting to note that all hybrid presses with digital capabilities displayed at Labelexpo Europe in September 2019 were fitted with UV inkjet digital presses. Leading press manufacturer who are offering Hybrids of flexo, digital and inline finishing include Gallus, Omet, Mark Andy, Nilpeter and MPS. With environmental concerns, migration of inks and other food or Pharma safety needs, non-waterbased inkjet systems may see more development in future. As of now due to the speed and versatility offered by UV Inkjet coupled with the ability to add additional white and other colours, UV inkjet is the predominantly used technology however investment is high. Therefore, selection of the best suited technology for digital in labels must be as per individual printer’s need and that of their diverse customer mix. It is a competitive time and cost of equipment, cost of consumables and the nature of output is very important to ponder over before finally selecting the first entry into digital.
