Patent ID: 7208263

Claim:
A method for making a photosensitive resin printing plate which comprises at least (1) an exposure step of forming a latent image in an aqueous-developable photosensitive resin layer of a printing plate material by irradiating the printing plate material with a ray of active light, (2) a development step of forming a relief image from the latent image by dissolving or dispersing the photosensitive resin layer that forms the latent image into a developer that contains water as a main component, and (3) a drying step of removing the developer from the printing plate having the relief image, wherein a photosensitive layer component-dissolved or dispersed in developer produced in the development step is subjected to reduced pressure distillation via a developer processing apparatus having at least a detachable inner container and a developer fly preventive device, and reused as a developer.
