Abstract
An apparatus comprises: (a) a rotatable drum configured to have a UV-curable printing plate with an ablatable layer thereon, placed thereon; (b) at least one laser beam to image the plate on the drum by ablating some of the ablatable layer according to image data to form an imaged plate; (c) an unloading area onto which a plate is movable when unloaded; and (d) a plurality of UV LEDs configured to cure UV-curable material on at least an imaged portion of the plate during the imaging process, such that imaging of one part of the plate and curing of an imaged portion of the plate occur simultaneously. In another embodiment, the plurality of LEDs are to apply UV radiation to the back of the UV-curable plate or to both the front and back of the UV-curable plate during or after the unloading of the imaged plate.
