Abstract:
A method for positioning engraving elements in an electronic engraving machine for engraving a printing cylinder for rotogravure, where at least two engraving lanes of predetermined lane widths lying next to one another in an axial direction of the printing cylinder are engraved in the form of cups with a respectively allocated engraving element, the engraving elements being positioned axially relative to the engraving cylinder before the engraving, comprising the steps of:with the engraving elements, implementing an axial feed motion along the printing cylinder during engraving; predetermining axial reference positions for the engraving elements, axial spacings thereof from one another corresponding to the predetermined lane widths of the respective engraving lane; successively positioning an electronic position measuring system to the axial reference positions; identifying an axial deviation of a reference point of the allocated engraving element from the reference position with the position measuring system in every reference position; and axially displacing the engraving elements with their reference points by the identified deviations onto the corresponding reference positions.
