a single manufacturing pass for manufacturing a multilayered self - organized coating onto a substrate to provide all of the functions usually provided in multiple - pass coatings for manufacturing an infrared imageable offset lithographic printing plate ; and a process whereby two or more polymeric materials that cannot usually co - exist in solution may be dissolved in suitably dilute solvent mixtures which , when coated onto a substrate and the solvents evaporated , deposit a continuous graduation of polymeric mixtures vertical to the substrate , caused by the self - assembly process .
