Sheetfed Maker To Demo LED UV Curing at Drupa

-- Graphic Arts Online, 2/22/2008

 
Ryobi introduced the model 1050, an 8-up 16,000 sph 40" press to be formally presented at the drupa printing exposition May 29-June 11 in Dusseldorf, Germany. Featuring double-diameter impression and transfer cylinders and an array of productivity options such as inline quality inspection, closed loop video color control and automated plate loading, the press becomes available for delivery one year after drupa. It’s to be offered in S format with a 41.34x27.95" print area—and the larger XL with a 41.34x30.31" print area. Ryobi says its aggressive price point will make it a highly competitive offering.
Ryobi will also present at drupa an inline foiling and casting unit, which was first displayed at IGAS in September. This device, which fits above the final flexo chamber coater on the Ryobi B2 format 750 press, prints patterned glue to which it impresses a foiler roll to print foiled patterns at press speeds up to 15,000 sph. The foil is flashed fused to the substrate by a UV lamp that penetrates the slightly translucent material produced by Kurz. The same unit can also be used to impress a cast pattern on coated substrates, creating holographic effects in the coating surface.
Ryobi also says it plans a technology demonstration of an LED lamp-based UV (shown above) curing system. Shown at the factory on a 525GX press, the lamp operates at one-fourth the wattage of conventional UV curing lamps and emits no ozone. Both the LED curing and foiler/caster were demonstrated during a press conference this week in Japan.
