<P>PROBLEM TO BE SOLVED: To provide a direct drawing type waterless lithographic printing plate precursor having good inking property. <P>SOLUTION: The direct drawing type waterless lithographic printing plate precursor has at least a thermosensitive layer and a silicone rubber layer on a substrate, wherein the thermosensitive layer has a center average roughness (Ra) of a surface of 25-200 nm. A thermosensitive layer surface is preferably roughened by dry etching, whereby the direct drawing type waterless lithographic printing plate precursor having good inking property can be provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
