摘要： A lithographic printing plate precursor, comprising a layer arrangement according to any one of the following (i) to (iv): (i) a support and an image recording layer; (ii) a support, an undercoat layer, and an image recording layer; (iii) a support, an image recording layer, and a protective layer; or (iv) a support, an undercoat layer, an image recording layer, and a protective layer, wherein: a layer containing a hydrophilic agent is included in the layer arrangement between the support and an innermost layer, between adjacent layers, or on an outermost layer other than the protective layer, the layer containing a hydrophilic agent contacts a region of at least one of, but not all of, the support, the undercoat layer, the image recording layer, or the protective layer, and an amount of sag of an end portion of the lithographic printing plate precursor is from 30 μm to 150 μm.

摘要： Provided is a planographic printing plate precursor including: a support; and an image recording layer formed on the support, in which the content of fine particles per unit area in a region on a plate surface on the image recording layer side from an end portion of the planographic printing plate precursor to a portion inside the end portion by 5 mm is greater than the content of the fine particles per unit area in a region other than the region by an amount of 10 mg/m2 or greater, edge stains are not generated therein, and transferring of the image recording layer is prevented even in a case where planographic printing plate precursors are stored in a stacked state. Further, provided are a method of producing the same and a printing method using the same.
