ABSTRACT:
Images are transferred to printing plates by illuminating light-responsive materials with patterns corresponding to the images to be printed. The present invention provides for the transferring of an image by the combined flux from two or more beams of light. Particular embodiments ablate the mask printing plates for CTP systems by the combined illumination from a first, broad beam and a plurality of controllable, pulsed beams that co-illuminate the plate with the first beam. The resulting system and method is less expensive than the prior art and produces a printing plate more efficiently and with improved productivity than the prior art.
