Abstract
A method for making a reusable printing plate in which a hydrophobic image area is formed on a hydrophilic plate surface containing a photocatalyst. The method includes the steps of carrying out a hydrophobic agent application process in which a solution containing an organic compound having a property of reacting with the plate surface by a heating process and a property of being decomposed by the action of the photocatalyst when irradiated by light having a higher energy than a band gap energy of the photocatalyst is applied on the plate surface; carrying out an image area formation process in which a part of the plate surface is subjected to a heating process to form a hydrophobic image area; and carrying out a non-image area formation process in which the organic compound applied to an area other than the hydrophobic image area on the plate surface is removed.
