Abstract
An idle distance of an engraving stylus for engraving a rotogravure printing cylinder is set from the cylinder surface of the rotogravure printing cylinder by use of a sliding element that is provided for the guidance of the engraving stylus connected to the sliding element along the cylinder surface during engraving. The setting of the idle distance is undertaken relative to a reference surface that is indicative of the cylinder surface.
