<P>PROBLEM TO BE SOLVED: To provide an original plate for lithographic printing which has a high plate wear without generating a flaw in a process and can print without applying developement treatment by carrying out laser exposure based on image information and to provide a printing method using that. <P>SOLUTION: For the original plate for lithographic printing, a hydrophylic layer and an image forming layer are successively provided on a plastic film base material, and heat fusible particle capable of being fusion welded by heat and a filler are contained in an image forming layer. When a film thickness of the image forming layer after heat fusion welding of the heat fusible particle is D(μm)and average particle diameter of the filler is R(μm), a relation: 1/5D≤R≤7D is provided. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
