The half-value width (b) of each projection is in a range of 5 to 300 times the height (a) of the vertex of the projection. Height (a) is in the range of 1-10 microns. Also claimed is a dry planographic printing plate comprising in order a base substrate, a photosensitive layer, a silicone rubber layer and the above cover film, where the cover film is laminated to the silicone rubber layer with the other smooth side of the base film contacting the upper surface of the rubber layer.
