Abstract
A method for producing a planographic printing plate comprising the steps of: producing an original planographic printing plate which comprises a substrate, and a first layer and an ink-repellent layer having an ink-repellent surface in that order on said substrate, wherein the first layer converts laser light to heat and enables peeling of upper layers disposed on said first layer; exposing said original planographic printing plate by laser light; and rubbing the surface of said original planographic printing plate, which is the surface of said ink-repellent layer, with a rubbing member in the presence of an aqueous solution containing a nonionic surfactant to physically remove laser-exposed portions of said ink-repellent layer, thereby forming the planographic plate, is provided.
