Storing Magnetic Cylinders and Dies: Best Practices

Proper storage and handling of magnetic cylinders and dies directly impacts their service life and the quality they deliver. These precision tools represent significant capital investments that deserve appropriate care.

Magnetic cylinder storage begins with cleanliness. Before storage, cylinders must be thoroughly cleaned to remove any adhesive residue, ink deposits, or debris. Even microscopic contamination can attract moisture, leading to corrosion that damages the precision-ground surface. A light coating of rust-preventive oil protects the surface, though this must be removed before the cylinder returns to service.

Environmental control is critical. Magnetic cylinders should be stored in a temperature and humidity-controlled environment, ideally between 18-24°C and 40-60% relative humidity. Rapid temperature changes can cause condensation that leads to corrosion. The storage area must be free from magnetic interference sources that could demagnetize the embedded magnets, reducing their holding force. Magnetic cylinders should be ideally stored with protective covers to prevent surface damage, and when not in use for short periods, pressure should be released to maintain precision tolerances. Cylinders should be stored on padded racks or in protective cases with soft linings. The precision-ground surface must not contact hard materials or other cylinders, as even small dents or scratches translate into cutting defects. Cylinders stored vertically minimize bending stress that could compromise roundness tolerances. In India and largely people use open racks to store.

Flexible die storage requires protecting thin, precision-etched steel from damage. Dies should be stored flat, never rolled, as rolling can permanently deform the cutting edges. Individual dies should be separated by protective sheets to prevent edge-to-edge contact that could chip cutting blades. Silicone release paper or polyethylene foam works well for separation.

Organization and identification are equally important. Dies should be clearly labeled with job information, date of manufacture or last use, and any specific setup parameters. This documentation prevents errors during setup and helps track die life and performance. Many converters maintain logbooks recording die usage, and performance notes to optimize die management and predict replacement timing.

Climate control for die storage parallels cylinder requirements. Steel is susceptible to rust, and even stainless-steel alloys used in some dies can corrode under adverse conditions. The storage environment should maintain stable temperature and humidity with adequate air circulation to prevent moisture accumulation.

Handling procedures matter as much as storage conditions. Dies and cylinders should be handled with clean, lint-free gloves to prevent skin oil contamination. Dropping or bumping precision tooling causes damage that may not be immediately visible but will manifest as quality defects during production. Magnetic cylinders should be checked for surface condition and magnetic field strength.

Additional Considerations in PSA Label Production

The pressure-sensitive adhesive label industry encompasses far more than die cutting alone, though die cutting remains a critical converting step that influences every aspect of label performance and quality.

Sustainability has emerged as a dominant concern. The label industry is working toward reduced material consumption through thinner liners, no-liner label technologies, and improved matrix efficiency. Die cutting plays a role through precision cutting that minimizes waste and enables thin liner applications. Some converters report matrix waste percentages below 15% through careful label design optimization and precision die cutting.

Quality control increasingly relies on vision inspection systems working in concert with die cutting stations. Cameras can detect incomplete cuts, die-strike damage, registration errors, and edge quality defects in real-time, triggering automatic press stops before significant waste accumulates. This integration of die cutting with automated quality verification represents a significant advancement over manual inspection.

Automation continues to transform label converting. Automatic die changes, powered by robotic systems or quick-change mechanisms, reduce setup times from 30-45 minutes to under 10 minutes. Automatic job changeover systems, fed by production scheduling software, sequence jobs to minimize die changes and setup time. These technologies are making short-run production increasingly viable, expanding the addressable market for pressure-sensitive labels.

Digital integration connects die cutting with upstream design and prepress systems. Label designs are created with die cutting constraints built-in, ensuring manufacturable shapes and avoiding features that would create matrix removal problems. Digital twin simulations can predict die cutting performance before physical production, reducing trial-and-error during setup and accelerating new product launches.

Future developments in die cutting technology continue to evolve. Research into laser-induced plasma cutting promises speeds approaching mechanical die cutting while maintaining the flexibility of digital systems. Ultrasonic cutting, using high-frequency vibration to assist mechanical blades, shows potential for difficult-to-cut materials. Water jet cutting, common in other industries, is being investigated for specialized label applications.

The pressure-sensitive label industry has traveled an extraordinary distance from Stan Avery’s first self-adhesive label produced in that flower shop loft in 1935. Today’s sophisticated converting lines, producing millions of precisely die-cut labels per day at speeds that would have seemed impossible even a decade ago, stand as testament to continuous innovation and refinement. Yet the fundamental principle remains unchanged—a precision cutting tool separating labels from their backing, enabling the convenience and functionality that pressure-sensitive labels bring to virtually every product we encounter in daily life.

The journey from flatbed presses cutting a few thousand labels per hour to modern rotary systems achieving 300 meters per minute represents not just technological advancement but a transformation in what’s economically and practically possible in product labeling. As laser systems mature, digital workflows integrate, and automation advances, the die cutting component of label converting continues to evolve. The future promises even greater flexibility, faster changeovers, and capabilities we’re only beginning to imagine.

For those of us who have witnessed the Indian label industry’s growth over decades, from its nascent beginnings to becoming a sophisticated, globally competitive sector, the technological journey of die cutting mirrors our own industry’s maturation. The precision, efficiency, and innovation embodied in modern die cutting systems reflect the same qualities that have driven successful label converters to build world-class operations capable of serving the most demanding brands and applications.

Die Cutting’s Impact on Matrix Removal and Rewinding

The die-cutting process extends beyond simply making cuts in the label material. Subsequent operations, including matrix removal—stripping waste material from finished labels—and rewinding the completed label roll, are directly influenced by the quality and parameters set during die cutting.

Matrix Removal: Challenges and Efficiency

Matrix removal difficulty is closely tied to blade height and cutting depth. When blades cut deeply into the liner, a pronounced score is left, which can make peeling the label easier. However, this can also lead to liner tearing during matrix stripping at high speeds. Balancing ease of label peeling with maintaining matrix integrity requires careful optimization, considering the specific application and production speed requirements.

Matrix removal efficiency depends on producing clean and complete cuts. If the die blade lacks sharpness or the cutting pressure is too low, labels may not separate cleanly from the matrix, resulting in tearing during stripping. Such issues generate waste and slow down production as operators must clear jams.

The shape of the label affects matrix removal as well. Small interior cuts, sharp corners, tight radius corners, and thin connecting strips in the matrix are more susceptible to tearing during stripping if die cutting is not precise. Dies should be designed with matrix removal in mind, sometimes incorporating relief cuts or modified geometries to reinforce the matrix in its most vulnerable areas.

Stripping Tension and Liner Integrity

Stripping tension needs to be carefully managed. If tension is too low, the matrix can bunch or fold, leading to unreliable stripping and potential web breaks. If tension is too high, labels may be pulled partially free from the liner if the kiss cutting depth is shallow, resulting in defects in the finished product.

Liner integrity after kiss cutting has a significant impact on rewinding quality and downstream performance. Liners deeply scored by excessive die penetration are more likely to break during rewinding, especially at the edges where tension is concentrated. This can cause production stops and waste. Even if the liners withstand rewinding, too much die-strike damage may result in failures when the label roll is unwound in applicators.

Edge Quality and Rewinding

Edge quality from die cutting influences how well labels are rewound. Rough or stringy edges can catch on to adjacent wraps as the roll builds, leading to telescoping (uneven roll sides) or starring (radial compression lines visible on the roll face). These defects compromise roll quality and may cause applicator problems when the labels are used.

Rewind tension control must consider the residual stresses introduced during die cutting. Materials stressed during cutting may display different tension characteristics compared to uncut material. Tension compensation is needed as the roll builds to maintain uniform roll density and prevent defects.

Diverse Types of Dies for Specialized Applications

Beyond the use of standard flexible and solid rotary dies, the label industry employs an array of specialized die types to meet the specific requirements of various applications and materials. These alternatives allow converters to address unique production challenges and enhance efficiency in niche scenarios.

Adjustable Dies

Adjustable dies are designed with removable blades, which can be replaced when worn or when different materials need to be processed. While less frequently used in narrow-web label converting, adjustable dies offer valuable flexibility for converters working with a wide variety of substrates, eliminating the need to keep extensive inventories of dies for each material type.

Combination Dies

Combination dies integrate multiple cutting functions into a single tool. For example, a combination die might feature both cutting and creasing blades, enabling the production of folding cartons or multi-panel labels in one pass. Perforation blades may also be included to create tear-off sections or features for easy opening. By consolidating several processes into a single die station, combination dies reduce the number of stations required, shorten setup times, and can improve registration accuracy by completing multiple operations in one controlled step.

Embossing and Debossing Dies

Embossing and debossing dies produce three-dimensional effects in label materials, enhancing visual appeal or providing tactile security features. These dies function through matched male and female patterns and require precise pressure control to ensure consistent depth without damaging the substrate. For embossing applications, magnetic cylinders with enhanced holding force are used to maintain die alignment under the substantial pressures involved.

Hot Stamping Dies

Hot stamping dies are used to transfer metallic or pigmented foils onto labels using heat and pressure. Although they are not cutting tools themselves, hot stamping cylinders are often integrated with die cutting stations for inline processing. These cylinders must manage both accurate temperature control and the mechanical requirements of maintaining the die or foil pattern in precise registration.

Perforation Dies

Perforation dies are engineered to create lines of weakness in materials, facilitating controlled tearing. The blades are precisely spaced, with cutting edges separated by gaps to produce an alternating cut-and-uncut pattern. The ratio of cut to tie length determines the ease of tearing and must be carefully designed for each application and material.

Micro-Perforation Dies

Micro-perforation dies refine the perforation process to produce nearly invisible perforations that still allow clean tearing. These dies are suited for security applications, pharmaceutical labels, and other situations where the perforation must remain hidden until use.

Normal vs. Laser-Hardened Dies

Choosing between standard dies and laser-hardened alternatives is a critical decision for label converters, balancing economic and performance factors.

Standard Dies

Standard dies are made from tool steel, CNC-machined to precise specifications, and heat-treated using conventional methods to achieve hardness levels between 52 and 58 HRC. These dies are reliable and cost-effective for many applications, making them ideal for short runs, prototyping, or processing less abrasive substrates. However, their limitations become apparent during high-volume runs or when converting abrasive materials such as thermal papers, thermal transfer stocks, or certain films. The cutting edge of standard dies gradually wears down and becomes rounded, which requires increased cutting pressure or slower line speeds. Eventually, dies must be re-sharpened or replaced, impacting productivity and increasing costs.

Laser-Hardened Dies

Laser-hardened dies employ focused laser energy to selectively harden the cutting edge, achieving hardness levels of 65-68 HRC, and up to 80 HRC for specialized chrome-coated versions. The laser hardening process creates a shallow, hardened zone at the cutting-edge tip while retaining normal hardness in the rest of the die for flexibility. This selective hardening significantly extends die life, sometimes by two or three times compared to conventional dies, reducing tooling costs per thousand labels produced. The harder edge stays sharper longer, ensuring consistent cutting quality and less frequent die changes or press adjustments. The hardened surface also reduces friction and adhesive buildup, preserving cutting quality and cleanliness. For converting abrasive thermal materials, laser-hardened dies may be the only practical option for achieving satisfactory production runs without constant maintenance.

Economically, laser-hardened dies are favored for high-volume applications. Although their initial cost may be significantly higher, their extended life and reduced downtime offer a compelling return on investment when producing millions of labels. Standard dies remain a better choice for short runs or frequently changing designs, given their lower upfront cost.

Alternative Die Cutting Technologies

While rotary die cutting is the mainstay of label production, alternative technologies are increasingly important for specialized applications and are gaining market share.

Semi-Rotary Die Cutting

Semi-rotary die cutting blends elements of flatbed and rotary systems. The web advances intermittently, while the die rotates. This hybrid mechanism enables fast changeovers and digital registration, making it ideal for digital-flexo hybrid presses where variable data printing is combined with die cutting. Although slower than full rotary systems, semi-rotary die cutting offers flexibility valuable for short runs and custom labels.

Laser Cutting: The Future of Label Die Cutting?

Laser cutting technology has advanced greatly, now serving as a viable alternative to conventional die cutting for many uses. It utilizes a focused laser beam to cut or perforate materials through controlled ablation and vaporization.

CO2 Lasers

CO2 lasers, operating at a 10.6-micron wavelength, are most used for labels, effectively cutting organic materials like paper, PET films, and polypropylene. Fiber lasers, working in the near-infrared spectrum, are gaining popularity for metallized materials and multi-layer constructions.

Laser cutting provides several advantages. Without the need for physical dies, setup times are reduced dramatically, and new patterns can be loaded within seconds. This makes laser cutting ideal for very short runs or custom labels where die costs would otherwise be prohibitive. Digital files allow for rapid design, iterations and customization, supporting personalized packaging and limited-edition products. Laser cutting delivers exceptional precision, enabling features as small as 0.1 mm and positional accuracy measured in microns. Complex shapes, small text, micro perforations, and other demanding features can be executed digitally with consistent quality.

However, laser cutting has limitations that prevent it from taking over high-volume label production. Speed is the primary constraint; even the fastest laser cutters lag behind rotary die cutting in throughput. Complex shapes further slow the process, making laser cutting less attractive for intricate designs despite its precision. Material compatibility also poses challenges. Some materials may release toxic fumes or reflect laser energy, making them difficult to cut. The heat-affected zone around laser cuts can cause discoloration or melting, impacting aesthetics or peel characteristics.

Operating costs for laser systems include high electrical consumption, regular replacement of laser components, and advanced exhaust systems to manage fumes and vaporized material. These costs must be considered when comparing economics to conventional die cutting. Despite these challenges, laser cutting is well-suited for security labels, pharmaceutical serialization, prototyping, and ultra-short runs. Hybrid systems that combine digital printing and laser cutting are expanding options for brand owners seeking customization.

Plotter-Type Die Cutting: Speed and Capabilities

Digital plotter cutting systems use a computer-controlled knife or blade, guided by digital patterns. The cutting head moves along X and Y axes, with blade depth controlling penetration, enabling kiss cutting, through cutting, or creasing. Modern plotter systems can achieve speeds up to 60-80 meters per minute for simple shapes, though complex cutting paths reduce throughput. Their advantage lies in flexibility—job changeovers require only loading a new digital file rather than changing physical tooling.

Plotter systems excel in prototyping and short-run production. Design firms and brand owners can quickly produce physical label samples from digital artwork, accelerating product development. Custom labels in small quantities are economical without traditional die setup costs. Registration capabilities have advanced through camera-based systems that read registration marks, automatically compensating for printing variations and keeping cuts aligned. Some systems can even adjust for material distortion or skew, ensuring precise cutting.

Plotter cutting is compatible with many materials, though extremely stretchy materials may deform rather than cut cleanly, and abrasive materials can accelerate blade wear, requiring frequent replacement and increasing costs. Plotter systems are economically superior for runs below 5,000-10,000 labels, where die costs are the largest expense. As volume rises, slower speeds and higher per-unit costs make rotary die cutting more practical. The crossover point depends on label complexity, material, and die life expectations.

Hybrid workflows that combine digital printing and plotter cutting are enabling new business models, such as print-on-demand label services with no minimum orders or tooling charges. Variable data capabilities allow each label to be unique, supporting serialization, personalization, and limited-edition launches.

Die Cutting in PSA Labels: From Stan Avery’s Innovation to Modern Laser Technology-Part 1

Die Cutting in PSA Labels: From Stan Avery’s Innovation to Modern Laser Technology-Part 1

The pressure-sensitive adhesive labels industry owes its existence to a struggling clerk working in a loft above a flower shop in downtown Los Angeles. In 1935, Ray Stanton Avery, who went by name Stan, was living in near poverty, residing in a rented chicken coop while working at the Midnight Mission to pay his way through college. What he created with a $100 loan from his fiancée Dorothy Durfee would transform how products are labeled worldwide and launch an industry that today generates billions in revenue.

The Genesis: Stan Avery’s Revolutionary Label

Stan Avery didn’t just invent the self-adhesive label, he invented the entire machinery to produce it. Using parts from a washing machine motor, a sewing machine, and a saber saw, he created and patented the world’s first self-adhesive, die-cut labeling machine. His company, initially named Kum Kleen Products, advertised the ability of these labels to be removed without leaving a mark on merchandise. The first Avery labels were simple, round price stickers meant for gift shops and retailers. In his first six months of operation, sales totaled a modest $1,391. Few could have imagined that this humble beginning would evolve into Avery Dennison, a Fortune 500 corporation with global operations across more than 50 countries and 36,000 employees worldwide.

The innovation Stan Avery brought to market solved a fundamental retail problem. Before pressure-sensitive labels, merchants relied on gummed labels that required moistening with water or paste, a time-consuming and messy process. Avery’s self-adhesive labels eliminated this inconvenience entirely, creating a faster and more practical labeling solution. His vision extended beyond the label itself to include the machinery for precise die-cutting, which would become the foundation of label converting technology.

By 1940, Avery had moved beyond his humble beginnings and officially started selling his products under the brand name Kum Kleen Price Stickers. The company incorporated in 1946 as Avery Adhesive Label Corporation, and in 1990 merged with Dennison Manufacturing to form Avery Dennison. Throughout his career, Stan Avery received 18 patents for his innovations in pressure-sensitive materials and production technologies. His legacy lives on, not just in the company that bears his name, but in every self-adhesive label produced today.

The Evolution of Die Cutting Technology

Die-cutting itself predates Stan Avery’s innovation by nearly a century. The process was invented in the mid-1800s to help the shoemaking industry. Cutting leather soles for shoes by hand was laborious, time-consuming, and expensive. The invention of the die-cutting machine revolutionized cobbler work, allowing shoes to be cut to consistent sizes and shapes rather than crafted individually. This standardization enabled modern shoe sizing as we know it today.

Flatbed Die Cutting: The Foundation

The earliest die-cutting machines used in the label industry were also flatbed presses. These hydraulically operated machines use a steel rule die to “click cut” or punch out die-cut parts by driving the die in a downward motion through the material. The flatbed die-cutting press operates much like a stamp, pressing a flat die onto material that sits on a stationary surface, applying even pressure to cut the material into the desired shape with each strike.

Flatbed dies are used with hydraulic or mechanical presses and other lifting systems to press a die down on a sheet of material. They are particularly suited for heavier materials and thicker substrates, making them less ideal for pressure-sensitive labels but excellent for applications requiring precision cutting of rigid materials. Steel-rule die cutting uses a formed strip of hardened steel set into a slotted plywood die-board, with rubber ejectors aiding part release after the cut.

While flatbed die cutting adapted for labels, offers excellent control over each cut and is ideal for intricate shapes with close tolerances, it operates at a considerably slower pace compared to rotary systems. Typical speeds range from 1,000 to 5,000 cycles per hour, making it suitable for small or mid-sized batches but impractical for high-volume label production. The tooling costs for flatbed dies are significantly lower than rotary alternatives, and the ability to make quick die changes makes them valuable for short-run or prototype jobs.

The Rotary Revolution in Label Converting

The transition from flatbed to rotary die cutting marked a transformative moment in label converting. Rotary die cutting uses a solid cylindrical die that rotates continuously in sync with the web material, paired with an anvil cylinder. The press feeds thin, flexible material, known as web, between these two cylinders. The cutting-edge pinches material against the anvil cylinder, producing clean cuts, perforations, or creases at exceptionally high speeds.

This method revolutionized label production by dramatically increasing throughput. Modern rotary die-cutting systems can reach 10,000 cycles per hour or more, with the fastest machines achieving speeds of 300 meters per minute. The ability to perform inline with printing and other finishing operations means that labels can be printed, die-cut, matrix stripped, and rewound in a single pass, transforming manufacturing efficiency.

A series of gears or servo motors now, force the die to rotate at the same speed as the rest of the press, ensuring that cuts line up precisely with the printing on the material. Rotary presses can incorporate multiple stations that die-cut specific shapes, perform perforations, create creases, or even cut the sheet or web into smaller sections. Some machines use automatic eye registration to ensure cuts and printing align with tolerances measured in fractions of a millimeter, critical for complex label designs and high-quality output.

The economics of rotary die cutting favor high-volume production. While the initial tooling costs are higher than flatbed alternatives, the operational efficiency brings labor expenses down over time. For standardized, repeat orders running into millions of labels, rotary systems offer compelling long-term value and unmatched productivity.

The Magnetic Cylinder Revolution

While the exact inventor and date of the magnetic cylinder for flexible dies are not definitively documented in available industry records, this innovation transformed the economics and flexibility of rotary die cutting. The magnetic cylinder system addressed a fundamental challenge: solid engraved rotary dies were expensive to manufacture, store, and transport, making them cost-prohibitive for short to medium production runs.

Magnetic cylinders are precision-engineered metal cylinders embedded with powerful magnets, either ceramic or neodymium rare earth magnets, on their surface. They are designed to hold flexible dies—thin, etched steel dies—firmly in place during rotary die cutting. The magnets ensure that every square inch of the flexible die remains securely pressed against the precision-ground cylinder surface, preventing any lifting or shifting during high-speed operation.

In 2005, Bunting Magnetics launched the X-treme Magnetic Die-Cutting Cylinder, the first magnetic die-cutting cylinder in the world with total run-out accuracy below 40 millionths of an inch (1 micron). This level of precision was revolutionary, enabling clean cuts even on extremely thin materials like 1-mil stock with less than 1-mil liners, on “no-look” labels, and on synthetic materials that previously posed challenges.

The advantages of magnetic cylinders transformed the label industry. Mounting and removing flexible dies takes just minutes, dramatically reducing downtime during job changeovers, particularly valuable in short-run label printing or multi-SKU packaging environments. The cylinders weigh significantly less than solid rotary dies, reducing operator fatigue, machine wear, and transportation costs. Most importantly, they enabled the use of flexible dies, which cost a fraction of solid engraved cylinders and could be stored flat, saving valuable warehouse space.

Today, magnetic cylinders are available for virtually all types of label presses and converting machinery, from brands like Mark Andy, Gallus, Nilpeter, Omet, Rotoflex, etc. Custom designs accommodate a variety of special applications, making magnetic cylinder systems remarkably versatile.

Flexible Dies: Engineering and Innovation

The development of flexible dies went hand in hand with magnetic cylinder technology. Flexible dies are thin sheets of steel, typically ranging from 0.5mm to 1.5mm in thickness, that wrap around magnetic cylinders and are used for rotary and semi-rotary presses. These dies are produced from specially formulated steel and undergo several sophisticated manufacturing processes.

Manufacturing Process

Production of flexible dies begins with plotting an image directly on the die material. Background material is then removed through chemical etching, and CNC mills create the required cutting or creasing lines with extraordinary precision. The cutting geometry includes profile heights ranging from 0.3mm to 1.5mm and cutting angles that vary based on the material being cut, typically from 30° to 110°.

The manufacturing process includes several optional treatments. Back grinding ensures consistent die thickness. Chemical de-burring smooths edges to prevent damage to the label stock. Most critically, laser hardening and various surface coatings dramatically extend die life and performance.

Die Materials and Surface Treatments

Standard flexible dies are CNC-sharpened and feature smooth polished cutting edges obtained using ultra-fine edge polishing techniques. These universal dies are suitable for all types of self-adhesive and single-material products including paper, PP, PE, PVC, PET, Tyvek, thin films on PET liner material, and other materials that are difficult to cut.

Laser hardening represented a breakthrough in die technology. Companies like Kocher + Beck were the first manufacturers in the world to achieve hardness levels of 65 to 68 HRC through laser hardening technology. This process extends die service life by two to three times longer than conventional dies. The laser hardening increases hardness at the tip of the cutting edge based on the carbon content in the steel, creating exceptional wear resistance while maintaining die flexibility.

For extremely demanding applications, chrome-coated dies offer even greater durability. A thin layer of chromium, typically 0.01mm thick with a hardness of 70-80 HRC, enables extremely high running performance with outstanding wear properties. These dies are particularly suited for abrasive thermal and thermal transfer papers used in longer production runs.

Non-stick coatings represent another important innovation. Special onyx or polymer coatings have no detrimental effect on the cutting-edge angle or sharpness while preventing adhesive and ink deposits on the cutting blades. These coatings are food-safe, FDA-approved, and significantly reduce downtime for die cleaning. The reduced friction and perfect resistance to wear enable maximum running performance with a consistently sharp cutting edge.

Sadhya means banquet in Malayalam. It is a vegetarian feast prepared by both men and women, especially when needed in large quantities, for weddings and other special events. Sadhya is typically served as a traditional dish for Onam, the state festival of Kerala. It was a feast for the eyes to see, a diverse gathering Indians and foreigners relishing the local cuisine and eating with bare hands.

Past president Sandeep Zaveri updated the audience about the next program of Round tables, the interaction between sponsors and Printers.

“Round tables” program with all sponsors attending to a rotating groups of label printers was a much-appreciated part of this conference. 

It gave the sponsors opportunity to interact with existing and prospective customers. This program was highly appreciated by the sponsors.

The final evening sponsored by Avery Dennison was themed “The Great Gatsby!”. 

American author F. Scott Fitzgerald that follows a cast of characters living in the fictional towns of West Egg and East Egg on prosperous Long Island in the summer of 1922. Fitzgerald—inspired by the parties he had attended while visiting Long Island’s North Shore—began planning the novel in 1923,

desiring to produce, in his words, “something new—something extraordinary and beautiful and simple and intricately patterned.” In the novel the character Gatsby throws very extravagant, excessive parties with hundreds of guests, all for the purpose to attract a lady’s attention. The evening had the settings of the 1920s.

The evening began with a vote of thanks by LMAI treasurer Dinesh Mahajan of Prakash Labels.

It was then time for SMI Managing Director Ajay Mehta’s talented daughter Nikita Mehta who trained in the USA and is all set to go professional in the Indian singing arena, to go on stage and give a melodious heartwarming singing performance.

Finally, while people enjoyed photo ops and networking over drinks.

Bollywood singer Nakash Aziz took the stage while the LMAI conference delegates hit the dance floor and enjoyed the fun until late in the night.

Credit goes to Hemal Bhagwat who heads the event management company Mercury Integrated along with her husband and a dedicated team. “Thank you Hemal for making this a memorable event, memories will linger on till it is time to plan yet another better and bigger LMAI CONFERENCE”

Trigon Digital Solutions, successful in digital printing of labels

Trigon Digital Solutions, successful in digital printing of labels
On the 22nd of November 2018 at the LMAI Avery Dennison Awards night, held on the side lines of Labelexpo India, the winner announced in digital printing category-Wine and Spirits was Trigon Digital Solutions, Mumbai. Just over a week later, on the 29th of November 2018, Trigon was declared the Printweek India “Digital Printer of the year”. This was Trigon’s fourth award; the first two were Printweek “Pre-press Company of the year” awards won in 2015 and 2017. It is an incredible performance by a company promoted by first generation entrepreneurs just 10 years ago, with no previous experience in running a manufacturing company. They moved into roll form digital printing of labels merely 3 years ago. They have invested in a digital printing press at a time when we are witnessing the evolutionary shift of label production in India from conventional processes to digital. Digital printing is a segment of label industry that leading label manufacturing companies have been extremely hesitant to invest in, due to high cost of equipment and consumables. Anil  Namugade the co-founder, along with partner Milind Deshpande, have promoted Trigon Digital and successfully led it on its digital label journey.

 

After graduating in Economics from Mumbai University Anil Namugade, also a Printing Technologist from the Government Institute of Printing Technology, took up jobs as a scanner operator from 1994 to 1997 in few of the leading pre-press houses in Mumbai. Here he acquired immense knowledge in repro-colour separation and prepress. In 1998 he joined Heidelberg as a software specialist and continued to work there until 2003. Anil joined Kodak as packaging and proofing specialist in 2003. It was a purely technical job where he developed his passion for proofing, learnt the nuances of colour management and the imperative need of good prepress for excellence in final print. During his stint with Kodak he was also handling technical and sales support which helped him gain experience in selling as well. Unfortunately, by 2007 Kodak was seeing a decline in business and as restructuring process was being put in place, he had to exit Kodak. Suddenly that one day he found himself jobless, away from a stable job in an MNC(Multi National Company). He firmly believed in and followed a simple mantra of success and excellence; “Look at problem as an opportunity and learn to grow and excel”. Drawing inspiration from this mantra, he along with partner Milind Deshpande who is also a printing technologist, set up their maiden start-up venture Trigon Digital Solutions. 

 

From past experience and knowledge he had acquired from working in the previous jobs, Anil knew that customers needing packaging, wanted to see how their product would look, before they opted for actual printing and production. He saw the opportunity in this need, so Trigon was set up as a proofing and mock-up producing company. His knowledge of prepress and colour management helped him to achieve his goal. Earlier it used to be the creative agencies that visualised and created a format for packaging, Trigon creating an actual marketable mock up for the companies was a new and welcome development for brand owner companies. The first equipment they invested in was Kodak Approval NX that printed in sheet format and started to take up proofing and mock-up creation for customers. Finding success in their endeavors he soon realised that being closer to the customer is an imperative.  In 2010 Trigon opened a facility in Bangalore and followed it up by setting up a unit in Delhi in 2012. In 2015 they went international by setting shop in Dubai and later an office in Singapore. All the units except the office in Singapore are equipped with Kodak Approval NX.

 

In 2015 they saw the opportunity in customers demanding label mock-ups in roll form, so in their Mumbai facility they invested in an Epson Surepress to produce samples including Flexibles, Laminates and Labels by digital printing in roll form. Moreover, the production on Kodak was turning out to be expensive and limited to sheet format. Soon their customers upgraded from demanding just mock-ups to ordering short runs for their specialised marketing needs.  They also started to see business emanating from the shrink sleeve segment as also a growing demand for other roll form variants. The slow speed of Surepress could not cater to the demand they were getting and also there was a limitation that it could not produce shrink sleeves. At this time in 2017 Trigon decided to take a major step of investing in an HP Indigo 6000 digital press and enhance their capability to produce a larger range of products. A year down the line in 2018 Trigon yet again upgraded their HP Indigo 6000 to HP Indigo 6900 which had enhanced features. On this HP 6900 they could do inline primer coating saving them the time and valuable space, print metallic inks and florescent inks. With a widened customer base and enhanced capabilities they now cater to applications in FMCG, Liquor, Personalised labels, Variable Data labels, QR codes and a lot more. They now produce and sell a range besides labels, offering flexible packaging, complex laminates, lamitubes and shrink sleeves. Anil Namugade firmly believes that digital is the future of printing and innovative packaging. Dwelling on the general apprehension of label printers regarding ROI (Return on Investment), he feels that it becomes better from an expanded vision of providing specialised services to the customer. These services that Trigon offers include brand management, database management including validation, preparing the mock-ups for test marketing before indulging extensively, offering creativity to customers for their evaluation and aiding decision making, personalisation or customisation and incorporating variable information on each label or package at short notice. Their experience in pre-press has helped them greatly and he believes that by adding full post press setup Trigon has become a one stop shop for the needs of brand owners. The additional cost of digitally converted products needs to spell value for customers to justify the cost. Anil asserts that the vision for success of flexo graphic printing and Digital printing should be looked at separately and not as a comparison. 

 

Trigon Digital Solutions plans to remain focused in digital Printing. With already a facility in Dubai and an office in Singapore they are a global entity and they will be expanding their global reach by establishing a setup in U.K. in 2019-2020 as they already have customers in 18 countries including UK and Europe. They have endeavored to remain logistically close to customers to be able to provide service at their doorstep. Surprisingly due to their business model of being linked to packaging development, marketing and brand management, their revenues do not come from purchase budgets of customers but come from their marketing budgets. Trigon making optimum use of space operates out of around 1800 square feet shop floor area of all facilities put together. Headquartered in Andheri East, Mumbai they have a workforce of 102 persons. At Trigon every new creation is a challenge but developing it is not. Anil proudly says innovation, technology, extensive knowledge of prepress, and having “People with Passion” in their team has always been a winning force for Trigon. They are committed to improve upon what the customer wants or brings to them for creation of a label or package that will spell success for their products and brand.

Waste matrix removal in label production

Waste matrix removal in label production
Waste matrix stripping or removal in production of self adhesive labels is a very important part of label conversion and is an imperative that leads to a web of labels which can be dispensed on automatic label dispensers in high speed packaging lines. Even though it sounds to be a simple process of stripping the ladder like extra waste after die cutting of labels, yet it remains to be one of the most complex and problematic area of label converting process. A problem with waste removal, like matrix breaking or labels lifting with the waste ladder may slow down the machine or in some cases make it extremely difficult to remove it online. Converters may have to resort to removing the waste manually offline making the process unproductive and costly. A host of parameters affect the process and it is difficult to address the issue in a singular way. With so many variables that impact the waste removal process, it is difficult to predict a simple solution. It could be due to the shape of label, size of label, release liner, face stock, adhesive, die cutting process, speed of conversion, die blades or the design of the waste removal section that may affect the correct and efficient removal at the optimum machine speed. Any of these may impact the final result and slow down the machine and the printing process. No one solution can apply to all problems. The traditional waste rewinding system is gradually becoming unpopular due the fact that tension is the key to efficient waste rewind. The rewound waste matrix ladder roll has empty spaces from where labels have been die-cut and as the roll becomes bigger there is lot of irregular tensions leading to breaks. As the market becomes extremely competitive with rising prices of labelstocks printers tend to reduce the gap between the labels to 2mm making the process even more difficult. This article will dwell on most of the variables mentioned here above.
 
Release Liners: The most widely used base papers as release liners in self adhesive label materials are glassine, super calendared Kraft and clay coated Kraft. These are uniform caliper, densified and non porous papers that have adequate strength and accept a uniform coating of silicone giving excellent releasing properties to become a proper backing for self adhesive papers. In recent years due to possibility of recycling and reducing the tonnage of waste generated, filmic liners also are being used as backing in labels. Release liners play a major role in die cutting and in turn impact the waste removal process. The die blade has to cut through the laminate and stop at the face of the liner so has to achieve a perfect half cut or kiss cut. The uniform thickness or caliper of the liner is an imperative. If the liner has variations, it will create problems at die cutting and eventually at waste stripping. If the release gets thicker the die will pierce the liner making a through cut and exposing paper fibers to the adhesive.  This also may result in web breaks. If the liner gets thinner, the die will not cut resulting in labels lifting with the matrix. Release level of the liner is also very important. If the release level is tight the matrix will tend to break due to tension and if it is too easy, labels will tend to lift with the ladder. Uneven silicone coating or pinholes in coating may also create problems. If the labelstock prior to waste matrix removal goes through a nip roll that has excessive pressure between them, the edges may develop micronic nicks that may render the face paper susceptible to web breaks. The paper rolls may also develop these rough edges in transportation and mishandling. The web needs to be inspected thoroughly before taking up label conversion.
 
 Face Paper:  Paper and films are generally used as face materials. A fairly high strength paper will perform well if all other parameters are addressed. If the gap in labels is too small, 2mm or less, the matrix will tend to break repeatedly. Moisture content in paper should ideally be between 3.5% and 5.5%; sharp increase in moisture will affect the strength adversely. The tensile strength of paper at Relative Humidity (RH) up to 50% is maximum after which it moderately decreases with RH up to 65% and on further increase in RH, it drops sharply. The uncoated papers are hygroscopic, so they tend to absorb moisture faster than coated papers. Evidently weather and storage condition of paper does have an impact on waste removal. Even when using emulsion based adhesive if the adhesive is not dried properly, the face paper will tend to absorb the residual moisture from the adhesive and result in deterioration of paper and affect waste stripping. In case of filmic face stocks, weather may not impact but the condition of die and quality of die cutting does play a major role. If the die is damaged or blunt it may not cut properly resulting in label lifting or film tear.
 
Adhesive: Commonly available labelstocks are coated with either emulsion based or hot melt pressure sensitive adhesives (HMPSA). In both cases for a perfect waste removal it is necessary that the die cuts through the adhesive as well, as otherwise if the coated film of adhesive is not cut, labels will lift with the matrix. Emulsion adhesives have good die cut ability however hot melt adhesives for better die cutting properties have to be specially selected. In case of HMPSA if the waste is not lifted immediately after die cutting the adhesive may rejoin and lift the labels with the matrix.

 

 

Size and shape of a label: These are parameters that are customer driven based on their specific needs, so the converting company cannot request changes from customer.  Small labels have a very limited area of contact and reduced tack holding it to the release liner and with little force the label may fly off or lift off with the matrix. In such a case die makers suggest packing self adhesive foam in the die shapes so as to push the label back on the release liner. Other times printers have found limited success in addressing this problem by increasing speed of the web. Waste ladder removal of irregular and complex shaped labels with sharp corners like in a star shape, is even more complex to handle. This becomes even more difficult in substrates like BOPP where a small nick may lead to web break. Converters need to slow down the machine to a great extent to finish the labels online. Machine manufacturers have addressed this issue of handling complex shapes as explained later in this article.
 
Die design: The die has a definite role to play in waste matrix removal. The subject is extensive and can take a full article to dwell on the nuances. The blade angle, blade height and coating on the die are factors that lead to ease or difficulty of label conversion.  Thickness of the face materials, type of adhesive and thickness of release liners are all imperative inputs that are needed before a die is put into production. A die that is designed for paper material is not recommended for filmic materials. Blade angle for paper is kept wider so that after penetration of around 80% into the paper the rest of the cut happens by crush or bursting of the material before stopping at the surface of the liner. In case of filmic face material a sharper acute angle is needed to pierce the film as in case of a wider angle the film will stretch and not be cut. An acute angle blade appears to cut better but wears off faster than the wider angle blade dies. Depending on the materials used the die angle varies between 45degrees and 110 degrees. The blade height needs to be adjusted to cut through the face, which maybe paper or film or a laminate, and adhesive without piercing the release liner. If any of the parameters is not right, the waste matrix removal will become a challenge. If the blade pierces the liner even slightly, it may expose the release paper fibers to the adhesive and get stuck to them causing waste ladder breakage. If the blade does not cut through the adhesive, labels will lift with the matrix. In case of coated materials like direct thermal and thermal transfer the coatings on the paper are abrasive in nature and tend to make the die wear off soon. In such case laser hardened dies are recommended. Adhesive sticking and building up on the dies also results in uneven cutting and also resulting in early die wear off. This is more evident where aggressive high tack hot melt adhesives are used. For this reason special non stick, coated dies are available so that the adhesive will not stick to them. The standard gap between the magnetic cylinder and the anvil is also very important as in case of die wear off the gap increases resulting in spaces where labels are not cut and would lift off with the matrix and to get a perfect cut the die pressure is increased. This results in faster wearing off of the bearers leading to a smaller gap and over cutting. Care has to be taken in die storage and handling. Before commencing any job proper inspection of die should be done regarding cleaner blades, blunt edges or nicks. The dies need to be stored in an environment avoiding excess humidity which may result in rusting.
 
Machine manufacturers have been consistently making efforts to address the issue of waste matrix removal to aid faster converting. Some of the steps taken include; 1.Lifting the waste matrix immediately after die-cutting. 2. Taking the die to a larger diameter stripping roller that would support the waste ladder on separation rather than a thin diameter roll that would provide a sharp angle to waste being stripped off. 3. By rethreading the paper in such a manner that the label web is peeled off the matrix instead of the matrix being pulled off. 4. De-laminating the web and re-laminating it before die cutting as this would reduce the tension required to peel off. These measures did help to some extent but complex shapes and a host of issues and factors that impact this process have had machine manufacturers continuously researching this area to keep implementing changes. One such solution that came around some years back was suction of the waste matrix into a suction and shredding system. This does take care of the tension and also manages waste by cutting it to small pieces and compacting it, but such systems have other problems. They are expensive, large in size so difficult to be fitted on presses due to lack of space, costly to operate as they use extra motors, compressor or vacuum and very noisy to run. Yet there is a brighter side to it, there is development going on to separate the waste and recycle it inline so as to reduce the impact on environment.
 
 
The larger established press manufacturers seem to have reached a viable solution. Some years ago they have introduced a big innovation in the industry by designing a simpler contact system rewinder for waste matrix. The idea was very simple; instead of pulling only the matrix up to the rewinder, we pull the entire web up near the rewinder. Here the matrix is peeled off against an idle roll and immediately pasted on the rewinder. Basically this reduces the travel of the matrix from 1 meter to hardly 5 cm and the journey is even supported by a roll. This system has now become the standard with many label press manufacturers

Spilker: German precision in tooling!

Spilker: German precision in tooling!
Story of  a family run enterprise Spilker GmbH, where three generations have technically indulged to grow their venture  from humble beginnings to attain success at global levels. They strive to upgrade and cater to customer needs maintaining quality standards assuring reliability in German precision!

Humble beginnings
In 1963, Herbert Spilker, trained as an engraving master, set up his startup venture in a small garage. Without any equipment and relying on his engraving skills, he started engraving metal brass plates for trophies with the barest minimum hand tools. With three children to support, a son Andreas the present Managing Director of Spilker GmbH born in 1961, another son and a daughter, he worked hard all by himself to grow his maiden engraving enterprise. In 1970s he felt it was time to move ahead. Self adhesive labels were evolving at a fast pace and the die cutting process was in the process of transforming from flat bed die cutting to rotary die cutting. Herbert Spilker wanted to produce flat bed dies but as luck would have it, prospective customers were already considering moves into faster converting process using rotary dies. They resisted his offer for flatbed dies and advised him to consider supplying rotary dies which at that time were being supplied by only two companies i.e. Kocher+Beck and Gerhardt (now merged into Rotometrics). The delivery time was very long, almost 2-3 months. Herbert was convinced that rotary dies was the business to be in. In 1978 he produced his first rotary die engraved by hand for a company Ritter Etiketten, now a part of the Rako Group since 2006. That was the beginning of an exciting journey to success in rotary tooling.
 
The first step towards expansion
 
Herbert Spilker
A year later in 1979 Herbert Spilker’s son Andreas, also trained as a master engraver joined the company as its 12th employee. The other son preferred to venture out as a printer but his daughter did join the business and now looks after the HR (Human Resource) department of the company. When Andreas joined the company they were still working without any machinery. They bought solid metal blanks and outsourced all other turning, machining and grinding processes. Finally the father son duo “master engravers”, would complete the die engraving by hand. In 1981 with experience of having produced 25-30 dies,they decided to invest in used turning and grinding machines. The turning machine at that time cost 1000 DM or 500 Euros. The grinding machine was more expensive at 2500 DM. The Spilker enterprise took it’s first big step of buying a CNC machine for engraving and then there was no looking back. In 1988 they moved to their present building in Leopoldshohe, it was a big step and time to expand!
 
In the late eighties the cost of rotary dies was making label printers consider using the cheaper but slower flatbed cutting options. The costlier solid rotary dies made it imperative to sell labels at a higher price making it difficult to compete. Flexible dies developed in America and  much cheaper than rotary dies, started being imported by others into Germany. These were instantly opted for by label printers to maintain their production speeds and consistent quality. Once in their new premises, in 1988, Spilker GmbH invested in equipment to produce both magnetic cylinders and flexible dies. Andreas Spilker proudly states, “No one taught us how to make these flexible dies and magnetic cylinders, we learnt it all ourselves” he further added, “It was the need of our existing customers, so the investment and development became an imperative”. The next decade was spent in consolidating, growing the new business, expanding and making renovations in whichever department it was needed. Herbert Spilker a farsighted man understood the need to transfer management to the generation next at an appropriate time. He mentored his son and transferred the power step by step until 1998 when he decided to retire and hand over the reigns of his growing business to his son Andreas Spilker, the present Managing Director. In 2003 Spilker installed their first machine for milling and sharpening rotary dies. Till then dies were sharpened by hand. They were the first manufacturer to offer rotary dies sharpened by machines. In 2004 the variabase anvil roll was developed for adjusting the cutting depth. In 2005 flexible dies in bigger format 860mm X 1050mm were developed. Spilker also has now capability to produce magnetic cylinders in very wide width up to 2800 mm. In 2006 they developed their first rotary die cutting machine. In 2008 they added another 3200 square meters to their production shop floor. In 2013 the MEP (Mechanical Ejector Pins) dies were developed. In 2015 another 300 square meters hall was added to develop custom built die cutting and laminating machine, such equipment was showcased at the Labelexpo Europe in September 2017.
 
The Family in business

Spilker continues to grow and attain global success. Andreas, a technocrat himself and a hands on
Andreas Spilker, Harveer Sahni, Henrik Spilker & Anika
 technically indulgent business owner, attributes this success to the inertia set in by his father Herbert Spilker. Even the day when this interview was to take place, Andreas was busy on the shop floor managing a new development. He is technically involved in all technical aspects of his company. His wife Katja is a home maker. Two out of his three children are already in the company. His daughter Anika born in 1990 and son Henrik born in 1988, joined the business in 2006. Henrik trained in metal engineering as a milling machine operator. After a stint in the company left to join university in 2010 and graduate in engineering. He returned to the company in 2015 to pursue his passion for technical innovation in workplace. He now looks after development of new tools, machine development and automation. Anika who has been in the company since 2006 is a refreshing personality, an imposing leader and leading her team by delegation. However still, her authority is evident in her area of operation.  She takes care of sales of rotary tools and in recent times has been passionately indulgent to grow the machine building business. Her husband is a police officer. The youngest offspring of Andreas, Marie at 19 years is still studying and only time will tell if she too joins the family business. The entire Spilker family are technology driven, Andreas remarked that none of them are accountants or management experts. “We can hire professionals for that but I am happy that the family is involved in production so as to turn out excellent, technically advanced and precision engineered products.
 
Getting over difficult times
 
Flexible die in production
The economic slowdown of 2008 brought the most difficult time at Spilker. Ironically and with regret,at that time they had to give up loyal employees to stay afloat. The crisis came at a time when they had acquired an additional shop floor area from a neighbor to expand their production. They had to stall the production until things improved and they were back on their feet. Once out of recession they came out stronger and fit to carve out a path of permanent and fruitful growth. Spilker with 210 employees presently works out of shop floor area admeasuring 20,000 square meters or over 200,000 square feet. Sales at over 20 million Euros continue to grow steadily at 10% per annum. They try to find special solutions to customer’s problems and attend to them completely, offering combination of new processes and products. They endeavor to make perfect rotary dies helping customers to build required production systems to service their respective customers. Andreas says, “The more complicated is the problem, the better it is for us. We love challenges”.
 
 
custom converting machine


The present business is spread into three business segments;
 
·         Rotary tooling that include rotary dies and magnetic cylinders
·         Flexible dies
·         Custom built machines

The above segments cater to the following industries;
 
·         Labels and printing
·         Medical and Pharmaceuticals
·         Automotive supplies
·         Electronics.



 
Magnetic Cylinder in production
A walk through their factory shows perfect workflow, state of the art capital equipment and testing systems to turn out products of highest quality standards. New developments at Spilker include tools with nonstick coatings for clean cutting adhesive labels with aggressive adhesives, tools for adhesive tape and wound care products, MEP systems with ejector pins for medical plasters that have holes, Sonic dies for punching holes and suction of waste rounds, etc. As for expensive rotary dies they offer value to their customers by repeatedly sharpening the tools when they become blunt. 



Andreas is pensive in his thoughts about his future in the company. He asserts that now that his children are getting firmly involved in the running of Spilker, in 5 years he will like to leave the management to them and retire. His daughter Anika is optimistic on the future and asserts that the company will grow further in both label and non label segments. Both Henrik and Anika are making efforts to expand into machine building while maintaining the quality and growth of existing business. Indulgent youthful attributes guided by an experienced mentor parent is sure to take Spilker to another level of success.
