摘要： The present invention discloses a method for making a lithographic printing plate comprising the steps of: (1) image-wise exposing an imaging element having on a hydrophilic surface of a lithographic base a photosensitive layer comprising a photosensitive polymer containing aryl-diazosulfonate units; (2) and developing a thus obtained image-wise exposed imaging element by mounting it on a print cylinder of a printing press and supplying an aqueous dampening liquid and/or ink to said photosensitive layer while rotating said print cylinder. Excellent printing results are obtained with a printing plate perpared according to the above described method. The lithographic base may be an anodized aluminium or a support provided with an ink-repellant layer containing a cross-linked hydrophilic binder.
