Abstract
A method for preparing a lithographic printing plate not requiring dampening with water comprising the steps of imagewise exposing to light a presensitized plate for use in preparing a lithographic printing plate not requiring dampening with water which comprises a substrate provided thereon with a light-sensitive layer and a silicone rubber layer in that order and then spraying a pressurized liquid on the plate surface to remove the silicone rubber layer of the image areas. The method does not require the use of brush rolls or developing pads which directly come in contact with the plate surface and give rise to wear and/or bending. Therefore, the method always ensures excellent quality and uniformity of development. Further, the method may be carried out repeatedly with less maintenance of equipment since it is not necessary to use any developing pad or brush roll which must frequently be exchanged due to wear or bending.
