Additionally, the laminated foil offers a smoother print surface and more opacity than metalized paper. The acrylic topcoat ensures that, you can’t see fibers. ” “Ink was selected based on its high strength for CMYK and extraordinary opacity for white, as well as high curing properties of all colors. It’s highly pigmented and guarantees heavy solids and process halftones,” proclaimed Rick Duarte, Pro ColorFlex Ink Corp. “ Color is very bright. Coverage is consistent. Curing takes place at high speeds. Its versatility is evident via good adhesion to a wide variety of substrates.” Jon Fultz of Fujifilm, who utilizes Pro ColorFlex as a West Coast distributor, concurred. “ T he FLEXO cover project provided a unique opportunity to apply one Fujifilm ink and varnish set for multiple substrate types and to demonstrate the adaptability of the inks in an environment where multiple anilox technologies and sizes were required. “Primary adhesion, laydown and opacity of the SuperNova White to the mylar cover was very good along with four-color process adhesion and intercoat adhesion,” according to Fultz. “ T he white was applied with one hit using an APEX GTT medium roll. As density readings were taken according to FIRST principles on the initial runs, some adjustments were needed... As a result, inks were based back in some cases to bring the densities within FIRST specs. ” Speaking to FIRST, Fultz sequed into its application in raw materials manufacturing. “ Fujifilm applies the principles of FIRST to ink manufacturing by constant measurement and improvement of the numbers—not just viscosity, color, gloss and adhesion measurements, which are common practices in the industry, but by measuring second and third level parameters to assure our ‘constant conditions’ are applied to every batch made. These parameters include environmental condition, holding batch sizes consistent, incoming raw mate- rial measurements, quality control and many more. ” Agfa Pitman’s Douglas Staggs, who arrived with a Techkon and Xrite spectrophotometer in hand to capture measure- ment data, decreed, “Harder plates and firmer stickyback are critical to this job. DuPont Cyrel DFQ FAST thermal processed plates offer resilency to gear marks, accommodate high line screens and characteristically afford low dot gain and strong highlights.” As the conversation changed from consumables to heavy equipment, Nilpeter’s Kent Wolford offered, “Design and engineering delivers results. It’s all about control of the web throughout different stages of the job. Servo drives assist us in promoting quality as we maintain the integrity and regis- ter of the print.” FINAL ASSESSMENT Staggs commented, “I was confident to use a prepress/ pressroom package that is part of Best Label’s daily workflow. The substrate proved to be more than a challenge. Utilizing FTA guidelines and processes was a key factor in determin- ing which direction we needed to move in. FTA solid ink density (SID) and dot gain targets were a starting point and a consideration in building the actual G7 curves/ ICC profile, but as with any special project it became a tool to benchmark against. From a numbers standpoint, the modified end result was conducive to the process and aligned with expecta- tions—nothing new to flexo. The key here is the use of a pro- cess that utilizes measurement practices and documentation that shows you ‘ where you are,’ ‘where you need to go,’ and ‘how you got there.’” Fultz was also complimentary in his assessment. “ T he final result was a very impressive demonstration of the significant leap forward flexography has taken.
