Abstract
A method for forming a lithographic printing plate requiring no fountain solution, which comprises the steps of irradiating a lithographic printing plate precursor requiring no fountain solution comprising a support having a layer for converting a laser beam to heat (first layer) and a layer having an ink-repellent surface (second layer) provided thereon in this order with the laser beam absorbable by the first layer to conduct image exposure, pressing an adhesive sheet layer on the second layer, the sheet having a surface layer adhesive to a surface of the second layer, and thereafter separating the adhesive sheet, thereby forming an image which makes it possible to perform printing requiring no fountain solution.
