Abstract: Provided is a plate-making method for producing a waterless lithographic printing plate, wherein the method comprises: (I) an exposing step of imagewise exposure of the precursor with a laser with a controlled condition that a portion of a laser-exposed area in a photo-thermal conversion layer in the precursor remains in the photo-thermal conversion layer of the finished printing plate, and (II) a developing step of removing a silicone rubber layer in the laser-exposed area to form an image on the printing plate. The precursor to be processed comprises (A) a support, (B) an undercoat layer formed by applying onto the support a coating liquid that contains a water-soluble or water-dispersible polymer and water as a solvent, and then drying the coating liquid, (C) a photo-thermal conversion layer which comprises polyurethane and a photo-thermal converting agent; and (D) a silicone rubber layer, laminated in that order.
