Abstract: Imagewise differential oleophilicity is formed on a planographic printing member by imagewise photoexposure, generally with a Yag laser, of an aluminium silicate image forming layer, generally of a boehmite hydrate layer such as is formed by contact of anodized or other aluminium substrate with sodium silicate. A print resistant image may be formed by applying to an image surface having imagewise differential oleophilicity a selective coating composition comprising an organic phase, generally in an amount of 90 to 75% by volume, containing film forming resin and that will preferentially wet and deposit resin on the image areas, and an aqueous phase, generally in an amount of 10 to 25% by volume, that will preferentially wet and prevent resin deposition on the background areas, and hardening the resin.
