The invention is concerning the use of metallic silver in the exposed, developed, and fixated silver-halogenide photographic layer fixed on the solid support, for the production of printing plate. The effect is achieved by treatment with acidic aqueous solution based on cupric chloride and hydrogen peroxide, or by treatment with aqueous solution based on cupric chloride and sodium and/or potassium dichromate followed by washing, and drying the layer which can be remoistened, eventually with addition of glycerol, before the use.
