Abstract (en)
[origin: EP2090429A1] The method involves applying a printing form (2) of a pourable, hardenable coating material e.g. lacquer (3), on a hydrophobic surface in a printing machine by application devices (8, 9, 10). The coating material is hardened by ultraviolet or infrared irradiation or drying by irradiation devices (11, 12), where the hardened material exhibits a hydrophilic surface. The hardened material is removed by laser irradiation so that the hydrophobic surface of the printing form is laid open, where the printing forms with a carrier structure of steel or aluminum and a surface layer of nickel and copper. The coating material consists of amino group, carboxyl group and silane. Independent claims are also included for the following: (1) a device for imaging a printing form (2) an offset-printing form comprising a carrier structure and a surface layer.
