Electrochemical polymerization technique was applied to form an ink acceptable image on a lithographic plate. Aromatic monomers such as pyrene or carbazole could be polymerized even in their solid state by electrochemical oxidation. However, the polymerization took place selectively on the substrate. The polymers could be formed on stainless steel, platinum and nesa coated glass. The contact angles of as-prepared electrochemically polymerized films were ranging between 60-70 degrees versus distilled water. They could be improved to around 90 degrees by heat treatment. Surface treatment on the stainless steel substrate reduced its contact angle versus water to less than 20 degrees. A combination of the film and the substrate was tested as a offset pressplate. Good quality printing was obtained with this type of lithographic plate.
