Abstract

PURPOSE: To obatin clear prints of high-contrast for recorded information by applying laser beams to the surface of a lithoprinting plate having an ink grease-sensitive layer and a hydrophilic coating layer provided successively on a support to thereby dispense with the developing and washing steps.
CONSTITUTION: A lithoprinting plate is formed by laminating an ink greaes-sensitive layer 2 and a hydrophilic coating layer 3 successively on a support 1. The surface of this lithoprinting plate is irradiated with the laser beams of low intensity 4, medium intensity 5 and high intensity 6 to form an image portion having an area 4' where the whole of the hydrophilic coating layer and a part of the ink grease- sensitive layer 2 have been removed, a medium-depth area 5' where the ink grease- sensitive layer 2 has been exposed and a large-depth area 6' where the ink grease- sensitive layer 2 has been exposed. As support 1, there may be used all types of supports generally used for printing plates, such as plastic film, paper sheet subjected to a water- or solvent-proof treatment, and metal sheet, etc.
