Abstract: A method for the topically precise subsequent-engraving of printing cylinders wherein special marks are engraved in the cylinder and evaluated. The marks are engraved in the form of cups forming a cup track. The cups serve as reference marks for an axial feed and start of the subsequent-engraving in a circumferential direction. After the printing cylinder has been mounted in an engraving machine for subsequent-engraving, the cylinder is placed in rotation and the scanner is moved over the previously engraved cup track axially. A maximum of the signals received from the scanner is identified and a location of the maximum in the cup track is retained as a reference value for the axial feed during the following engraving. A cup track is provided with at least one defined gap that is free of cups. A first cup following the gap is identified by means of the scanner and evaluated as a reference location for a start of engraving in the circumferential direction for the following subsequent-engraving.

Abstract: An electron beam generating system provides a high degree of steadiness of the beam current and comprises a heated cathode, an auxiliary electrode lying at a more negative potential than the cathode, and a transpierced anode. A diaphragm surrounding the beam and connected to a precision resistor is further provided at that side of the auxiliary electrode facing away from the cathode. A portion of the beam current influenced by the control electrode is blanked out by the diaphragm. The precision resistor is connected as an actual value generator to a regulator which is connected to a reference voltage, the output of the regulator influencing the potential of the control electrode over a final control element for the purpose of maintaining the beam current measured by the diaphragm constant.

Abstract: Apparatus and method for engraving with an electron beam such that depressions of different sizes can be generated in the surface of a workpiece and the different sizes of depressions are produced by an electron beam and wherein during periods when depressions are not to be formed the electron beam remains on but is defocused so that it does not form depressions. A modification of the invention provides that at times when the beam is not being used to cut depressions that it is pulsed wherein the short pulses of the beam which engage the work surface do not do any cutting.

Abstract: In a device for engraving of cups into a rotating printing cylinder for rotogravure, at least one laser light source with which laser light for formation of the cups is directed onto the rotating printing cylinder. A metal removal element is arranged in a region of an impingement location of the laser light on the printing cylinder to form the cups such that a melt accumulation of material of the printing cylinder which forms a burr at the cups created by the impingement of the laser light is removed substantially continuously and substantially immediately after its creation with the removal element.

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.

Abstract: In printing form production with electron beams, the imaging scale of the electron source on the source of the printing form is modulated gradation-dependent for engraving different cup geometries. The power density distribution in the effective point of the electron beam can then be approximately rectangular for all gradations. In particular, engraving the small cups, which was hitherto a vertical factor, is thus stable.
