A method and associated apparatus for forming an image replication medium on a surface of a printing plate or cylinder in which the surface is initially coated with a layer of photopolymer liquid. Thereafter, selected areas of the layer of liquid coated on the surface are hardened by exposure to a beam produced by a computer controlled laser to provide a surface cylinder having an image replication medium with a desired pattern.
