Abstract
A system for preparing a photopolymer printing plate includes exposure unit comprising a plurality of UV light emitting diodes (UV LEDs), a holder comprising a UV translucent material configured to receive the printing plate, and a controller configured to activate the plurality of UV LEDs. The UV LEDs include a plurality of stationary back UV LEDs configured to emit UV radiation toward the non-printing back side of the printing plate through the holder with the printing plate disposed in a stationary position on the holder, the plurality of stationary back UV LED sources together defining at least one back array having a collective irradiation field covering an area at least coextensive with the lateral length and lateral width of the plate.
