<P>PROBLEM TO BE SOLVED: To provide a printing plate capable of forming a printing area on a printing plate without applying a printing area forming material. <P>SOLUTION: A printing plate, especially a printing sleeve or a printing plate has a printing plate supporting body (11) and a polymer layer (12) capable of forming and cancelling the printing area provided on the printing plate supporting body (11). On the polymer layer (12), the printing area can be formed by a light catalytic process and/or a photo-chemical process. The printing area of the polymer layer (12) is featured by being eliminated by removal by function of electromagnetic beam and/or function of heat, and/or function of at least one solvent and/or coming capable of being eliminated by removal by polishing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
