Method for making lithographic aluminium offset printing plates according to the DTR-process by photo-exposing a photosensitive monosheet layer assemblage comprising a hydrophilic aluminium foil, a water-swellable intermediate layer comprising a non-proteinic hydrophilic film-forming polymer, and a silver halide emulsion layer, applying an aqueous alkaline solution thereto in the presence of a developing agent and a silver halide solvent, allowing to reduce the photo-exposed silver halide, allowing the unreduced silver halide or complexes thereof to diffuse to said aluminium foil to form a silver image thereon, and separating said emulsion layer and said intermediate layer from the imaged aluminium foil. The invention also relates to the photosensitive monosheet layer assemblage used for making such printing plates.
