<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a novel lithographic printing plate with outstanding sensitivity, plate wear and print scumming performance and a printing method by which an image can be developed on a printing press using this lithographic printing plate. SOLUTION: This printing plate is manufactured by supplying a reducing agent (or a coupling agent) to the image recording layer of a lithographic printing plate material having the image recording layer containing a diazo compound (or a diazosulfonate compound) on a support. Light or heat is applied, in an image pattern, to the lithographic printing plate material and the reducing agent (or the coupling agent) of the diazo compound is supplied to the surface of the image recording layer and further, the lithographic printing plate material is mounted on the printing cylinder of a printing press. In addition, dampening solution and/or ink are supplied and the ink is transferred to a receiving element from the image recording layer. Besides, the reducing agent of the diazo compound is supplied, in an imaginal shape, to the surface of the image recording layer containing the diazo compound using an ink jet process, and the light or the heat is applied to the image recording layer and further, the printing plate is mounted on the printing cylinder of the printing press. In addition, the dampening water and/or the ink are supplied to transfer the ink to the receiving element.</p> |
