ABSTRACT:
The invention provides a process for making a lithographic printing plate utilizing silver image as ink receptive area which is markedly improved especially in printing endurance. The process comprises subjecting a light-sensitive material for lithographic printing plate to imagewise exposure and development and then treating the resulting silver image with an oxidizing agent and a monocyclic compound comprising a nitrogen-containing single ring and having substituents on at least two atoms constituting said ring, said substituents being capable of reacting with silver ion. The oxidizing agent and the monocyclic compound may be contained separately or together in a stop solution, a fixing solution, an etch solution or damping solution or especially prepared solution.
