Abstract

PURPOSE:To eliminate the decrease in adhesion power between the substrate and rubber layer, the deformation of drawn parts, etc. obviate the change in print resistance, and obtain the distinct printed matter by using a heating metal bar at the time of retouch-correcting the printing surface of the lithographic printing plate using a silicone rubber layer as an ink repulsion layer. CONSTITUTION:In the case of retouch-correcting the portions missing required places, particularly printing elements, characters, etc. in the lithographic printing plate comprising laminating a photo polymerizable adhesion layer 2 and a silicone rubber layer 3 on a substrate 1 and forming ink receptive parts 4, a metal bar 5 or the like comprising shaping the end of a precision soldering iron or the like to permit easy retouching is used and lines or spots are retoched by heating the bar 5 to 100 deg.C or more, preferably 300 deg.C or more. In this way, adverse influence to printing and the decrease in printing resistance owing to the deformation of the rotouched parts 6 or the decrease in adhesion power are prevented.
