description The invention relates to a photographic reproduction process which is based on the light sensitivity of dichromate and in which the light-sensitive layer is provided with a grainy structure by prolonged rolling onto the base. Above all a simple and reliable halftone reproduction, particularly effective image action and rapid developability are achieved by this simple measure. Expediently, additives which promote the grain structure during coating are added to the image layer.
