Re-imageable printing plate treating method, involves modifying surface working as printing surface, of plate in nanoscopic range while changing chemical end groups of surface, and applying absorbing layer on surface
The method involves modifying a semiconductor surface (106) working as a printing surface (104), of a printing plate (102) in a nanoscopic range while changing chemical end groups of the semiconductor surface. The printing plate is treated with an infrared laser radiation (124). A near infrared absorbing layer (112) is applied on the semiconductor surface. A mask (132) corresponding to information to be printed, is produced by the treatment of the printing plate with the infrared-laser radiation. An independent claim is also included for a method for printing information.
