Abstract
The regenerative plate making and printing process, and plate making and printing apparatus of the present invention are applied to a printing system requiring a separate developing step independent of a printing step. In accordance with the present invention, by repeatedly conducting (A) a photosensitive layer-coating step of coating a photosensitive plate material onto a substrate to prepare a photosensitive lithographic plate having a photosensitive layer thereon; (B) an exposure step of exposing the photosensitive layer to image light; (C) a development step of supplying a plate-treating agent to the photosensitive layer to form developed images thereon; (D) a printing step of supplying a printing ink and dampening water to surfaces of the thus obtained images to conduct printing; and (E) a substrate regeneration step of removing the image portions from the substrate to regenerate the substrate, on the same rotary drum or conveyer, it is possible to considerably improve the working efficiency and stably provide high-quality images.
