Plants & Processes Cyber Graphics in Memphis, TN Platemaking Like Never Before: Invest in Productivity and Get a Whole Lot More By Dan Rosen RESEARCH IN ACTION • Consumer product companies are requiring implementation of even more sustainability efforts in the supply chain, and they demand more vivid graphics, faster turn-around, and lower cost • Cyber Graphics, a leading prepress provider based in Memphis, TN, partnered with Flint Group Flexographic Products to explore the very best in platemaking technology • A three year project resulted in the recent installation of Flint Group’s nyloflex® APP (Automated Plate Processor) into Cyber Graphics’ Memphis facility • While automatic platemaking isn’t new, the nyloflex® APP system is able to run 16 plates back-to-back without operator handling and gets finished plates out in record time • A reduction in energy consumption was also seen, as two 52-in. X 80-in washers, plus one dryer could be taken off line after installation of the nyloflex® APP equipment • Customers report about a 25 percent reduction in the number of distillation cycles needed to reclaim their solvent Until the 1990s, making a flexographic printing plate was a labor intensive and sometimes unpleasant process. In the early days, rotary washout units were the norm in North America. While low cost and easy to service, these systems struggled with their ability to handle large sized plates. Exposure, washout, drying, and light finishing were often tricky to control, and the plates they produced were of inconsistent quality. Around 1990, the industry saw the introduction of several large format (52-in. X 80-in.) processors that incorporated plate washing and rinsing and delivered a dry-to-the-touch plate. A few years later, those same processors were modified with automatic drying and light finishing, integrating complete plate processing into a single unit. Subsequently, most of the innovation subsided. The new systems that were developed were mostly tweaks of older technology. The platemaking equipment market slowed significantly with consolidations and cost cutting trends. As a result, many of the platemaking systems we see in the North American market today are more than 10 years old and some of them even exceed 15 years of age. Times are not getting any easier for the flexo platemaking businesses. Platemakers are being required to hold finer and finer detail on photopolymer plates; customers for these plates are even more price sensitive, and the competition in platemaking is becoming more globalized. Consumer product companies are requiring implementation of even more w w w. f l e x o g r a p h y. o r g june 2012 FLEXO 37 sustainability efforts in the supply chain, and they demand more vivid graphics, faster turn-around, and lower cost. Faced with these challenges, Cyber Graphics, a leading prepress provider based in Memphis, TN, partnered with Flint Group Flexographic Products to explore the very best in platemaking technology. Starting with focus group discussions, an analysis was made of the pros and cons of the current platemaking equipment options available today. The culmination of a three year project resulted in the recent installation of a nyloflex® APP (Automated Plate Processor) into Cyber Graphics’ Memphis facility. “We’re always looking ahead to find the latest in technical developments, especially from Europe,” stated Rick Parker, director, operations and technology, Cyber Graphics. “Our customers expect us to create value through innovation. That sometimes means finding a better workflow and also investing in new production infrastructure. If we were to start resting on our laurels, that would be the time we’d start falling behind.” Echoing the need for innovation in the plateroom, Edwin Woods, director, Cyber Manufacturing Site was part of a large team that oversaw the complete renovation of the Cyber Graphics plateroom, with the new nyloflex® APP system as its Rick Parker, Steve Dearing and Edwin Woods of Cyber Graphics led a team charged with identifying a new lean workflow and investing in new production infrastructure, which brought innovation to the Cyber Graphics plateroom. Automation at Cyber Graphics includes utilizing design files to cadcut and label each plate.

We streamlined everything from the way raw plate material is brought into the room, to how it gets Q.C.’d, and how we ship those finished plates to our customers. And along the way, we needed to reduce the handling of materials and improve the consistency of every single plate we made.” Woods continued, “ Ultimately, we envision flexo platemaking as becoming almost hands-free, as is the case in other prepress technologies. We’ve developed proprietary systems including the automated cut-down and labeling of each plate, along with standard operating procedures and inspection systems to ensure we consistently produce the best quality plates possible.” But there is nothing new in automated platemaking. Where has the new nyloflex® APP system been able to improve the process? “Speed and ease of servicing,” reports Steve Dearing, manufacturing project leader, Cyber Graphics. “Simply put, the new plate processor can produce a typical .067-in. plate in about 40 percent less time when compared to other systems we’ve worked with. It is able to run 16 plates backto-back without operator handling and get finished plates out in record time. That makes the difference between a job that ships today and a job that sits until tomorrow.” Dearing added, “Previous automated systems were a lot of work to keep running properly. The design of the new plate processor reflects a lot of our requirements when it came to making the system easier to operate and maintain.” When asked for some examples, Dearing cited the following points: • Horizontal transfer of the plate through the entire process (no flipping or hanging in the processor) • Easy visual inspection of the plate right after washout with see-through panels all around the machine to monitor the processing operation Sludge! Or lack thereof. The nyloflex® APP system pre-washes the black layer off of digital plates, so carbon build-up like this does not get into your process. w w w. f l e x o g r a p h y. o r g Discover Your New Media Source for Seamless Imaging Photopolymer Sleeves Laser Engravable Elastomers No Plate Lifting No Plate Mounting Perfect Registration Every time. 1-888-478-0998 Transparency is not just a business term - the nyloflex® APP system allows operators to visually monitor the process. • A detailed color interface panel with internet connectivity for diagnostics, plus another input panel at the back of the machine for retrieving finished plates • Tool-free brush replacement that takes minutes instead of hours • A cleaner washout system that pre-washes the black carbon layer from digital plates without getting the rest of the processor dirty • A more ergonomic design: loading and unloading of plates below chest-level, safer than having to use step stools to access finished plates When asked to comment on the key performance indicators that interest platemakers in the automatic plate processor technology, P.J. Fronczkiewicz, product manager, Flint Group, said, “In the U.S., we are currently benchmarking the key benefits of the nyloflex® APP in partnership with Cyber Graphics.” “The company in Europe where the first automatic plate processor was installed already has more than one year of experience with the nyloflex® APP. The plate department headcount requirements were reduced by two people, and the three shift operation was consolidated into two shifts,” Fronczkiewicz continued. The firm also reported a reduction in energy consumption, as two 52-in. X 80-in. washers, plus one dryer could be taken off line after installation of the nyloflex® APP. Energy savings also came from the plate processor, which operates much more efficiently. “That’s because it has separate drying chambers for every two plates, meaning a smaller volume to maintain tempera- Table 1 40 FLEXO june 2012 w w w. f l e x o g r a p h y. o r g rotec® nyloflex® nyloprint® nylosolv® Automation & Standardization Benefit from automation and • Increase your productivity • Minimize process tolerances ture,” added Fronczkiewicz. “Platemakers really get excited when they realize the nyloflex® APP also uses less solvent than other platemaking systems. That’s due mainly to the viscosity control design used by the nyloflex® APP to manage solvent replenishment. With this technology, our customers report about a 25 percent reduction in the number of distillation cycles needed to reclaim their solvent.” Additional benefits of this technology are shown in the Table 1. “It is a big investment,” concluded Parker. “We could have continued to use older equipment or looked for something that was lower cost upfront. But we have to consider the big picture when it comes to labor, productivity, energy and maintenance. Most importantly, we had to find a way to respond to our customers’ needs for the fastest turn-around, while still maintaining premium quality. With all those things being considered, investment in the nyloflex® APP equipment was the obvious choice for us.” n • Improve plate and print quality • Enhance workflow efficency and consistency Highest automation in flexo for standardized flexo form processing nyloflex® Automated Plate Processor About The Author: Joining the flexographic industry 25 years ago, Dan Rosen works with Flint Group Flexographic Products, a supplier in the field of photopolymer plates and sleeves, in the position of sales director for National Accounts.
