Abstract: An LED-UV lamp that is easily interchangeable within a UV-curing process and scalable in length with a fine resolution so that it is easily customizable to any UV-curing application. The LED-UV lamp may incorporate multiple rows of LEDs and contain corresponding optics that effectively deliver radiant power to a substrate at distances of several inches.

Abstract: A device such as a row of wheels, a row of pressurized air blasts, or guide fingers is attached directly to a UV LED lamp that is mounted into a sheet-fed printing press for curing UV inks and coatings. The device will enable the UV LED lamp to be placed closer to the sheet than previously possible by preventing the trailing edge of the sheet from dragging across the UV LED lamp as the sheet passes by the lamp.
