摘要： In a device for engraving screen-based impression cylinders, particularly for intaglio printing, by means of an engraving element in an electronic engraving machine, an engraving element is controlled by an engraving signal which engraves a series of wells into the rotating impression cylinder line by line. The wells are arranged according to a screen defined by presettable engraving parameters, and their engraving depths represent the engraved tone values. To engrave the entire surface area of the wells, the engraving element moves in a feed motion along the impression cylinder in the direction of the axis of the impression cylinder. The screen geometry is determined by the peripheral speed of the rotating impression cylinder and the feed motion of the engraving element. By controlling the engraving machine using automatic process control, several sequential engravings with different engraving parameters, such as screen parameters, are carried out in one step on at least one impression cylinder with at least one engraving element. The sequential engravings are multiple engravings or re-engravings from first engravings.
