n39: Comexi’s EB printing technology and WetFlex®

Comexi Group and Sun Chemical lead the EB flexo market for Flexible Packaging

After 5 years of joint research and development, Comexi Group and Sun Chemical are pleased to announce the commercial availability of the first fully industrial solution for flexographic printing using Comexi’s eCOMEXI flexographic presses and the Sun Chemical WetFlex® ink system.

This technology was presented at Drupa 2008 on the Comexi Group booth, and today is ready to be used, with proven results, to print flexible packaging substrates.

The WetFlex flexographic electron beam curing ink printing process not only allows flexible packaging converters the use of a fully environmentally friendly technology, but also provides impressive quality and compliance advantages. This proposed solution guarantees total reliability in the heavy-duty industrial environment, achieving high printing quality with more than 70 l/cm, better brightness and a Comexi patented built-in inking system to secure full stability in the printing process. In addition, achieving such high print resolution allows our customers to compete more effectively in the markets which are traditionally dominated by gravure printing, with less cost per square metre as the print process is 100% VOC free.
