A method for processing a photosensitive lithographic printing plate (PS plate) and an apparatus therefore, the method comprising subjecting the PS plate to imagewise exposure and development, the PS plate comprising a hydrophilic support, a non-silver photosensitive layer being capable of forming a water-insoluble ink receptive image and formed on the hydrophilic support, and a silver halide photosensitive layer formed on the non-silver photosensitive layer, which comprises the steps of (1) or (2): (1) developing the silver halide photosensitive layer, without fixing the developed silver halide photosensitive layer, irradiating the PS plate with light for exposing the non-silver photosensitive layer through the silver halide photosensitive layer subjected to development and remaining unfixed, completing the irradiation such that the irradiation in every irradiated portion is within 3 seconds after the start of the irradiation, eluting the silver halide emulsion layer to remove, and finally developing the non-silver halide photosensitive layer, or (2) developing the silver halide photosensitive layer, without fixing the developed silver halide photosensitive layer, irradiating the non-silver photosensitive layer with light through the dried silver halide photosensitive layer, eluting the silver halide emulsion layer to remove, and finally developing the non-silver halide photosensitive layer. <IMAGE> |
