Abstract: In a method or machine for engraving printing cylinders for packaging, pattern, or wallpaper printing and equipped with at least two engraving members, each engraving member engraving elements to be printed into the printing cylinder and, for an areal engraving, executes a feed movement parallel to a longitudinal axis of the printing cylinder. To shorten engraving time, a print image or layout for the printing cylinder is subdivided into at least two circumferential engraving strips, one engraving member being associated with each engraving strip. At least one strip boundary is automatically placed between said engraving strips in at least one white space remaining unengraved between at least some of the elements to be printed.

Abstract: In a method for engraving printing forms for rotogravure on a printing cylinder in an electronic engraving machine with an engraving element charged by an engraving control signal that engraves a sequence of cups arranged in an engraving raster into the print cylinder engraving line by engraving line, by positioning elements to be engraved in the printing form the cylinder layout of the printing form is designed in a workstation (3) under visual control. The engraving data required for engraving the printing form are compiled from the engraving data of the individual elements according to the cylinder layout. During a test cut before the engraving, test cups are engraved into the print cylinder within a test cut region and their geomemetric dimensions are interpreted for calibration of the engraving control signal.
