PURPOSE:To prevent wasteful use of water, by processing a photosensitive lithographic plate with an aqueous solution containing a surface active agent immediately after the plate is developed by using the same developing solution which is repeatedly used. CONSTITUTION:A developing section is composed principally of a developing tank 1, carrying rollers 3, a brush roller 4, solution supplying nozzles 8, squeezing rollers 5, tandem roller pairs 6, receiving rollers 7, developing solution storing tank 10, and developing solution supplying pump 9 and, at the time of development, the pump 9 is actuated and a developing solution is supplied to a photosensitive lithographic plate from the nozzles 8. The used developing solution is squeezed by the rollers 5 and returned to the tank 10. Thus the solution is circularly used. A surface active agent solution processing section is composed principally of a surface active agent solution processing tank 2, carrying rollers 3', tandem roller pairs 6', squeezing rollers 5', and solution supplying nozzles 8' and supplies a surface active agent solution which is circularly used by means of a pump 11 to the lithographic plate coming out from the developing section through the nozzles 8'. |
