Apparatus and method for directly curing photopolymer printing plates, such as with UV radiation. Printing plates are cured directly by radiation, such as emitted from a high power UV laser beam. No LAMS layer or film bearing the image information is required on top of the polymer plate. The laser beam may be split into several individually-modulated beams by means of an Acousto Optical Deflector. Each individual beam is capable of curing pixels of the image that are to be transferred to the printing plate. Support shoulders for the printing details, formed by the pixels are determined by the caustic of the UV beam propagation.
