PROBLEM TO BE SOLVED: To provide a planographic printing plate processing apparatus preventing wavy variations which is not induced by an AM screen but first induced by high definition exposure, and free from an image defect. SOLUTION: The planographic printing plate processing apparatus has a developing step to carry and process a planographic printing plate coated with a photosensitive material where an image is formed by use of an FM screen or a high-definition AM screen while immersing the plate in a developer solution, and is equipped with both in a developer solution: a carrying guide plate disposed along the carrying line and on the back side of the planographic printing plate passing the developing step; and at least a pair of nip rollers to nip the planographic printing plate guided by the carrying guide plate. The carrying guide plate is disposed to keep the distance from the planographic printing plate passing over the guide plate always within 5 mm. COPYRIGHT: (C)2005,JPO&NCIPI |
