Title: METHOD FOR BAKING COATED PRINTING PLATES
Abstract:
The invention relates to a method for baking a coating of a printing plate carrier, wherein the printing plate comprises aluminium or an aluminium alloy as the carrier material, in which the printing plate is heated to a baking temperature, is kept at this temperature over a predefined period and is subsequently cooled down. The object of proposing a method for baking printing plate carriers, in particular printing plate carriers of a large format, in which the deformations after the baking operation can be minimized still further is achieved by providing that, at least in a temperature interval between 150°C and the baking temperature, preferably 100°C, the temperature differences of the temperature of the metal of the printing plate measured along a line in the longitudinal direction of the printing plate are a maximum of 40°C over a length of 40 cm during the heating up and cooling down, and the temperature differences of the temperature of the metal of the printing plate measured along a line perpendicular to the longitudinal direction are less than 10°C during the heating up and cooling down.
