Abstract:
An object of the present invention is to provide a manufacturing method for a lithographic printing plate precursor which can simplify a manufacturing step while maintaining the performance of preventing edge stains and in which there are neither setter contaminations nor vendor contaminations; the lithographic printing plate precursor; a plate manufacturing method for a lithographic printing plate; and a printing method using the above-described lithographic printing plate.The manufacturing method for a lithographic printing plate precursor of the present invention includes: an image recording layer forming step of forming an image recording layer as an a step; a coating step of coating a partial region of the image recording layer, which is formed in the a step, with a coating liquid containing a hydrophilic agent, as a b step; and a cutting step of cutting the lithographic printing plate precursor such that the region coated with the above-described coating liquid is in a range within 1 cm from the end portion of the lithographic printing plate precursor after being cut, as a c step, in which the c step is performed after performing either the a step and b step in this order or the b step and the a step in this order, on a hydrophilic aluminum support.
