Abstract

A method for developing exposed lithographic printing plate precursors using a developer and replenisher is disclosed. The replenisher contains a higher concentration of a coating attack-suppressing agent than the developer, so that the aggressiveness of the developer remains substantially constant during the developer loading cycle.
