Grafix USA (Booth 1861) is debuting Green-UV, an alternative to conventional UV printing that delivers instant curing of LED inks and coatings using two UV lamps specially tuned to the highly reactive inks’ wavelengths. As a cost-effective entry into UV technology, Green-UV opens up new lines of business for commercial print shops and package printers.
Green-UV produces stunning glossy effects and excellent rub resistance, like conventional UV, while affording the environmental benefits of printing with LED inks. Two UV lamps rated at 300 watts/inch can accommodate most process-color print jobs, including jobs printed with thick inks, running at normal press speeds. Located in the delivery of the press, the metal halide-doped lamps eliminate the need for interdeck UV lamps, as well as the standard three-lamp, end-of-press drying system. Sheets come off the press completely dry and ready for work-and-turn or immediate finishing.
Green-UV is simple to install and economical to operate. The lamp system significantly reduces energy usage. The curing process generates minimal infrared heat and is entirely free of ozone production. The lamps are cooled by a combined air and water cooling system. There is no need for ozone extraction.
