<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a photosensitive planographic printing plate, having high workability and realizing printing with superior plate wear, contamination recovering property, printability and dot quality of a print, and to provide its usage method. <P>SOLUTION: The method for manufacturing a photosensitive planographic printing plate which has a photosensitive layer, containing (A) a polymerizable ethylenically unsaturated bond-containing compound and (B) a photopolymerization initiator on a support body and which is exposed to laser light of 350 to 500 nm emission wavelength includes at least a coating step, a drying step, a cutting step, and inspecting/selecting step. Any one of the steps in the coating step, drying step, cutting step and inspecting/selecting step is carried out under illumination by a light-emitting diode lamp having 530 to 620 nm maximum emission wavelength. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
