摘要： 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.

摘要： An image-writing device writes a dot image onto an image-receiving body in such a way that the dots align at a certain screen angle. The dots are written by an array of writing elements such as light-emitting diodes. The image-writing device has a memory that stores compensation parameters that compensate for non-uniformity of the writing elements. The compensation parameters are also calculated to produce dots with approximately uniform widths as viewed in the screen-angle direction. When driven according to the compensation parameters, the writing elements produce a dot image that is comparatively free of dot-width irregularities aligned in the screen-angle direction, which is the direction in which such irregularities are most noticeable.
