Sun Chemical and Comexi Group have reported that its WetFlex technology has crashed through a landmark target of 500m/min printing. This technology, developed in a partnership between Sun Chemical, Energy Sciences Inc (ESI) and Comexi, was shown in public for the first time at drupa 2008.
WetFlex delivers wet-on-wet flexographic printing and is designed to meet the needs of the flexible packaging market for improved print quality, efficiency, and low environmental impact. WetFlex uses new generation energy curable ink technology specially developed and patented by Sun Chemical for the process.
At drupa, the inks were wet trapped using Comexi’s new iF2 Icube concept Central Impression (CI) cylinder press and cured instantly by exposure to ESI’s EZCure-DF EB in-line electron beam, which had been installed in a ‘short-web path’ press layout.
