PRINTING MATERIAL, ITS MANUFACTURING METHOD, METHOD FOR MAKING PRINTING MATRIX, METHOD FOR REPRODUCING PRINTING MATRIX AND PRINTING MACHINE

Document Type and Number:

Japanese Patent JP2005138378

Kind Code:

A

Abstract:

To enable reducing a light irradiation energy which is required for writing an image during making a printing matrix and erasing an image during reproducing the matrix, in the printing material with a layer containing a photocatalyst, a method for manufacturing the printing material, a method for making the printing matrix and a method for reproducing the printing matrix and a printing machine.

The printing material has a photocatalyst layer containing a photocatalyst TiO2 or a TiO2 compound, formed on the surface, and the volume ratio Ra of an anatase-type crystal in the total crystalline component of the photocatalyst TiO2 or the TiO2 compound, is 0.4 to 1.0. Further, the total volume rate of crystallization of the photocatalyst is not less than 20%.
