Provided is a method for manufacturing a sleeve printing plate that makes it possible to form an image pattern printed on an object to be printed by laser engraving without creating cracks, splinters, or the like in a printing plate comprising a photosensitive resin. The method for manufacturing a sleeve printing plate according to the present invention makes it possible to surround the external peripheral surface of a cylindrical sleeve body using a printing plate comprising a photosensitive resin, and to form an image pattern by laser engraving on the printing plate, wherein the method for manufacturing a sleeve printing plate is characterized in comprising a step for washing and cooling the printing plate by using water, a step for subjecting the printing plate to a heating treatment at a prescribed temperature, and a step for subjecting the heat-treated printing plate to a heat-releasing treatment. |
