Abstract
A device for engraving intaglio cylinders and similar printing forms having an engraving tool which, together with a sensing member sensing the surface of the printing form to be engraved, is mounted in a holder movable relative to the surface of the printing form. The sensing member is a distance measuring member which contactlessly measures the distance from the surface of the printing form. On the basis of the distance measured from the distance-measuring member, the holder is adjusted relative to the surface of the printing form by an adjusting element, for maintaining a predetermined tool distance between the engraving tool and the surface to be engraved.
