PURPOSE:To greatly improve one plate wear or the photosensitive resin intaglio printing plate by subjecting the printing plate to a heat treatment at a specific temp. after plate making processing. CONSTITUTION:A photosensitive resin intaglio printing original plate is subjected to the plate making processing mainly consisting of exposing, developing, drying and post-exposing and thereafter the resulted printing original plate is heat treated under a temp. condition of 80 to 350 deg.C at the time of making the photosensitive resin intaglio printing plate essentially consisting of a soluble polymer, ethylenic unsatd. compd. and photopolymn. initiator. |
