<P>PROBLEM TO BE SOLVED: To provide a highly plate wear-resistant original lithographic printing plate which solves the problems wherein an image is irregularly strained due to a stress caused by a distortion and elongation when a manufactured printing plate is bent along the circumference of a plate cylinder of a printing machine in mounting the printing plate on the plate cylinder, and shoots serious troubles such as impairing the precision of image superposition, image positioning and registering during multi-color printing such as color printing, and further, eliminates a noise during printing, and also to provide a printing method which uses laser irradiation based on image information and prints an image without performing a development process. <P>SOLUTION: In the original lithographic printing plate with at least an imaging layer formed on a support, a filler and a binder resin layer containing a spherical microcapsule encapsulating a pressure-sensitive adhesive which generates a tackiness under pressure, are formed on the back of the original lithographic printing plate. <P>COPYRIGHT: (C)2004,JPO |
