LED & Sheetfed UV

While LED lamps are old news on inkjet presses, they are something of a novelty on the sheetfed side.

“LED inks for inkjet [applications] have been available for a couple years now,” says Mike Sajdak, senior R&D chemist for INX (Schaumburg, IL). “They offer less heat generation, a smaller footprint and faster startup times. Offset LED inks are a little newer.”

At Drupa 2008, Ryobi (xpedx) teamed with Toyo Ink to showcase an LED-UV system for a concept demonstration on the 525GX, a 14 × 20-inch press.
