Abstract
A printer and a restoration method for a printing plate which can be reused, while coping with digitization of printing processes is provided. On a substrate serving as a hydrophilic surface mounted beforehand onto a plate cylinder, a toner image portion formed on the surface of a photosensitive material is adhered and fixed directly or via an intermediate body to thereby form an image area. In thus way, the substrate is divided into a hydrophobic image area having at least a 50° or higher contact angle with water and a non-image area having an ink repulsion property, to thereby form a printing plate. After completion of printing, the ink and wetting solution adhered to the surface of the printing plate are cleaned by a cleaning apparatus, and image area on the surface of the printing plate is then removed by a chemical treatment solution supply roller, to thereby restore the printing plate to the initial condition so that this can be reused.
