Process for making lithographic printing plate
摘要:
There is disclosed a process for making a lithographic printing plate, which comprises subjecting a lithographic printing material having at least a silver halide emulsion layer and a physical development nuclei layer on a support and having a sensitivity at a wavelength of 400 nm to 440 nm of 20 nullJ/cm2 or less, and having substantially no sensitivity at a wavelength of 450 nm or longer to scanning exposure by a scanning type exposure device on which a violet laser diode is mounted, and then subjecting to developing treatment.
