摘要： In a method for processing signals in an electronic engraving machine for engraving printing forms, engraving control signals for guiding the stylus of an engraving element are obtained from engraving data representing predetermined tone values between “light” (white) and “dark” (black). The stylus engraves a series of cups in the printing form. The cup depths determine the tone values actually engraved. Before engraving, the engraving control signals corresponding to “light” and “dark” are calibrated by adjustment variables so that the engraved “light” and “dark” tone values correspond to the predetermined “light” and “dark” tone values. So that the “light” engraved tone value remains constant when the “dark” tone value changes, the difference between the old “dark” adjustment variable and a new “dark” adjustment variable is formed before engraving. A new “light” adjustment variable is then calculated on the basis of this difference, and is used to automatically recalibrate the engraving control signals for “light”, so that the “light” tone value remains constant.

摘要： In a device for engraving screen-based impression cylinders, particularly for intaglio printing, by means of an engraving element in an electronic engraving machine, an engraving element is controlled by an engraving signal which engraves a series of wells into the rotating impression cylinder line by line. The wells are arranged according to a screen defined by presettable engraving parameters, and their engraving depths represent the engraved tone values. To engrave the entire surface area of the wells, the engraving element moves in a feed motion along the impression cylinder in the direction of the axis of the impression cylinder. The screen geometry is determined by the peripheral speed of the rotating impression cylinder and the feed motion of the engraving element. By controlling the engraving machine using automatic process control, several sequential engravings with different engraving parameters, such as screen parameters, are carried out in one step on at least one impression cylinder with at least one engraving element. The sequential engravings are multiple engravings or re-engravings from first engravings.

摘要： An engraving method and apparatus for engraving a cylinder for printing an intaglio pattern and/or non-intaglio pattern on a web of material. The engraver includes a driver for rotatably driving the cylinder and a computer for controlling the operation of the engraver and for generating an intaglio engraving signal corresponding to an intaglio pattern and a non-intaglio signal for a gravure pattern. The engraver also uses an engraving head for engraving the cylinder with the intaglio pattern and the gravure pattern during the rotation of the cylinder in response to the intaglio engraving signal and non-intaglio signal. The invention includes an intaglio engraved pattern and method for engraving engraved areas having bottoms which are generally planar.

摘要： An error detection apparatus and method for use with engravers, such as gravure engravers. An error value E corresponding to the difference between a set of predetermined setup parameters and actual measurement of a portion of an engraved area on the cylinder is determined. The error value E is then used to adjust the engraver to engrave an actual cut or etch in accordance with the set of predetermined setup parameters. The error detection and correction system is suitable for providing a closed-loop system for engraving a cylinder. The apparatus and method may be used during initial setup or during normal operation of the engraver. A method is disclosed comprising the steps of engraving ink receptive cells in the surface of a rotating gravure printing cylinder consisting of the steps of generating a cell width command signal comprising a series of cell width commands, engraving the cells by using the cell width command signal to urge an engraving stylus into periodic engraving contact with the surface, measuring actual widths of cells which have been engraved as aforesaid, and adjusting the cell width command signal in correspondence with differences between the actual widths and the cell width commands.
