ABSTRACT:
Disclosed are a method and an apparatus for processing with a developing solution repeatedly used, both an imagewise exposed, positive-working presensitized lithographic printing plate and an imagewise exposed negative-working presensitized lithographic printing plate. The plates each comprise an aluminum support and a light-sensitive layer formed thereon. A replenishing solution is added to the developing solution to compensate for the degradation of the developing solution brought about by development and/or by carbon dioxide in the air. The method comprises the steps of; measuring a reflection density of the light-sensitive layer of the printing plates to discriminate the type of the printing plate, selecting a predetermined developing condition according to the discriminated type of the printing plate, and developing the printing plates according to the selected developing condition.
