摘要：
The present invention relates to a method of regenerating a printing plate, a regenerating apparatus, and a printing press which make it possible to regenerate a printing plate for repetitive use and shorten the time of plate regeneration. In particular, the present invention intends to make it possible to shorten a time for decomposing and removing an image area formed with an organic compound under irradiation of an activating light. Furthermore, the present invention relates to a printing plate, a method of fabricating the printing plate, a layered formation, and a method of fabricating the layered formation. The present invention is arranged to include a photosensitive layer containing a photocatalyst and when the photosensitive layer is applied on the surface thereof with an activating light having an energy level higher than the band gap energy of the photocatalyst under a heating atmosphere, the surface of the photosensitive layer can be swiftly hydrophilized.
