In a method for engraving a printing cylinder using an engraving member in an electronic engraving machine, an engraving tool of an engraving member controlled by an engraving signal engraves a sequence of grooves arranged in a printing screen in a rotating printing cylinder. The engraving signal is formed by superimposing an image signal representing the shade values of light and dark of the grooves to be engraved and a periodic screen signal for generating the printing screen. In order to compensate for disruptive influences on the shade values of the engraved grooves resulting from operating temperatures in the engraving member, the operating temperature in the engraving member is measured at at least one measurement point. Depending on at least one measuring temperature, the electrical control of the engraving member is corrected and/or the temperature of at least one component of the engraving member and/or the air circulating around the engraving member is modified. |
