DuPont Packaging Graphics (DuPont) and Sun Chemical, two of the leading suppliers to the flexographic and packaging graphics industries, have joined forces to create a new standard in quality and environmentally smart flexographic printing by bringing together Sun Chemical’s patented WetFlex wet-on-wet flexographic printing process with its patented UniQure electron-beam cured inks and DuPont Cyrel FASTtechnology.

The joint work was focused on linking the WetFlex printing process with the DuPont 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.
Research and development teams from both companies worked together to determine the optimal Cyrel photopolymer printing plates for the WetFlex process.  The Cyrel Fast plates outperform all Cyrel solvent plates in terms of print quality and staying clean on press.  The combination of the WetFlex process and Cyrel Fast produces some of the highest print quality graphics ever seen.
“DuPont and Sun Chemical both are focused on innovations in printing that make a real difference to customers,” said Lisa DiGate, global business director, DuPont Packaging Graphics.  “We are very excited about continuing to work closely to push the boundaries of current flexographic printing technology to improve quality and productivity as well as environmental sustainability.”
DuPont introduced Cyrel Fast Digital, the first solvent-free platemaking process for flexographic printing and brought to market a system that lowers energy consumption and greenhouse gas emissions, and eliminates the impact solvents have on the waste stream. The rapid access platemaking system reduces total plate production time to less than one hour by eliminating the washout and drying steps.
“Working with DuPont to optimise 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,” said Richard Pettifor, president, North America Packaging, Sun Chemical.
