DuPont Packaging Graphics and Sun Chemical, two suppliers to the flexographic and packaging graphics industries, are collaborating to produce improvements in flexo printing by bringing together Sun’s WetFlex wet-on-wet flexographic printing process, with its UniQure electron beam cured inks, and DuPont Cyrel FAST technology.
“The joint work was focused on linking the WetFlex printing process with the Cyrel photopolymer plate technology and resulted in obtaining previously unachievable levels of print graphics, while providing the market with a solvent-free process that can contribute to sustainability improvements in printing and packaging,” says Lisa DiGate, global business director at DuPont Packaging Graphics, Wilmington, DE, USA.
R&D teams from both companies worked together to determine the optimal Cyrel photopolymer printing plates for the WetFlex process. The FAST plates outperform all solvent plates in terms of print quality and staying clean on press, says DiGate, adding, “The combination of the WetFlex process and Cyrel FAST produces some of the highest print quality graphics ever seen.”
“Working with DuPont to optimize the results of the WetFlex printing process helps flexography grow its position as the process of choice around the world for high quality, high-impact packaging,” says Richard Pettifor, president, North America Packaging, Sun Chemical, Northlake, IL, USA. “With two of the most innovative companies in the packaging market working to build end-to-end solutions for environmentally sustainable flexo processes – all while maintaining and exceeding the quality that brand owners demand from their printers – we can resolve the quality-versus-green conundrum for our industry.”
