Abstract:
A method for positioning engraving elements in an electronic engraving machine for engraving printing cylinders for rotogravure, comprising the steps of:respectively engraving in the form of cups at least two engraving lanes having predetermined lane widths lying side-by-side in an axial direction of the engraving cylinder with a respectively allocated engraving element; setting axial spacings of the engraving elements relative to one another before the engraving; executing with the engraving elements an axial feed motion along the printing cylinder during engraving; and for approximately setting the axial spacings of the engraving elements for the lane widths generating reference position marks for the engraving elements, the axial spacings of said marks from one another corresponding to the predetermined lane widths of the engraving lanes to be engraved on the printing cylinder; providing the engraving elements with axial position marks; and axially shifting the engraving elements such that the axial position marks are in coincidence with the respectively allocated reference position marks.
