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.
