PCT No. PCT/GB95/02782 Sec. 371 Date Sep. 18, 1997 Sec. 102(e) Date Sep. 18, 1997 PCT Filed Nov. 28, 1995 PCT Pub. No. WO96/20433 PCT Pub. Date Jul. 4, 1996There is described a method of preparing a water-less lithographic plate by coating a positive working photosensitive composition onto an oleophilic base imagewise exposing the plate and developing it to remove the areas of the photosensitive composition which have been light exposed, coating overall the surface of the plate with a layer of a composition which is ink-releasing or when cured becomes ink releasing, then either as a separate step or as a combined step curing the ink-releasing composition or drying the ink-releasing composition and light exposing overall the plate, then redeveloping the plate to remove the photosensitive composition remaining after the first development and any ink-releasing composition overlying the photosensitive composition.
