<p>PROBLEM TO BE SOLVED: To provide a plate making method for a photopolymerizable planographic printing plate which does not generate flare, etc., in a laser direct plate making, can give a clear image and has high printing resistance. SOLUTION: A photopolymerizable planographic printing plate with a photosensitive layer contg. (a) a compd. having an addition polymerizable ethylenically unsatd. bond, (b) a photopolymn. initiator system and (c) a binder is imagewise exposed with a fixed quantity of light from a laser exposure system, developed and exposed all over the surface with at least 100 times as much light at the above light.</p> |
