Abstract
A method for making a printing plate including a step of forming a hydrophobic image area on at least a part of a hydrophilic surface of a plate. The plate surface contains a photocatalyst and the image area is formed by using an organic compound which is decomposed and removed by the irradiation of light having a higher energy than the band gap energy of the photocatalyst.
