Definitions

  • the invention relates to a color control system for printing presses, in particular sheetfed offset printing presses, which serve to control a large number of remotely actuatable adjusting means, in particular zone-wide ink metering elements, in order to be able to supply the ink differently across the printing direction.
  • the ink to be printed is fed via lifter inking units and ink fountains along with ink fountain rollers.
  • metering devices interacting with the ink fountain roller which are designed, for example, as an undivided or divided ink knife or as zone-wide ink metering elements, the ink can be supplied differently to the printing direction in accordance with the ink requirement of the printing form.
  • the ink metering device of an ink fountain roller consists of a multiplicity of zone-wide ink metering elements
  • each ink metering element is designed as a remotely operable actuating means which comprises an electrically controllable drive and a position transmitter and can be actuated via corresponding control electronics.
  • the remotely operable adjusting means in each printing unit can then be controlled by a color control system assigned to the printing press after a specific inking unit has been selected.
  • the "inking unit" command button is provided on the color control system.
  • Each remote-controlled actuator has a pair of command buttons on the color control system assigned, whereby a command button corresponds to "less color” and a command button corresponds to "more color”. Additional command buttons can be provided on the color control system, for example command buttons for the remote adjustment of the lifting strip width and lifting cycle, command buttons for format selection, command buttons overall less printing ink or more printing ink etc.
  • Such color control systems are for example from EP 0 047 926 A1 and DE 3 826 383 A1 known. It is also known to assign a display device for the remote actuating means to the color control systems. These display devices can consist, for example, of screen devices or also each of a row of light-emitting diodes assigned to the color metering zone. In the representation of the positions of the color metering elements (color profile) on a monitor, for example, the position of each color metering element can be provided by a bar of a certain length. The color profiles can also be displayed simultaneously in all inking units.
  • inking units of sheetfed offset presses are very slow transfer systems. If the ink guide is changed in a inking unit, i.e. changed from one color profile to another color profile, a large number of sheets go through the printing press until the new color profile is reflected in a final coloration on the printing sheet, that is to say a new steady state in the coloration is reached.
  • DE 3 904 301 A1 has already proposed that the change from one color profile to another be carried out in an “overdrive” manner (“dead-beat method”). Color metering elements which are adjusted from a starting position to an end position (new setpoint) should therefore be moved for a short time to an intermediate position which is larger or smaller than the respective end position.
  • this "overstroke” is very careful to the printing process as well as to the actual conditions is coordinated in the inking unit.
  • an automatic control that does this is not yet known.
  • Color-matching desk 1 serves as a base for a printed sheet 2, which advantageously runs inclined towards the viewer. Stops 3 are present on the color-matching desk 1, for example in the form of rails, so that the printed sheet 2 can be placed with its edges in a defined position. The stops 3 for the side edges of the printing sheet 2 are adjustable according to its format.
  • a row of command buttons "less color” 4.1 - 4.n and a row of command buttons "more color” 5.1 - 5.n are arranged below the lower edge of the sheet and towards the operator.
  • Each of the n color metering zones or each of the n color metering elements is thus assigned a pair of control elements of the "less color” command buttons 4.1 - 4.n and the "more color” command buttons 5.1 - 5.n.
  • the entire width of the arrangement of these control elements corresponds to the maximum format that can be printed on the printing machine transversely to the printing direction - furthermore, the distances between the individual control elements correspond to the width of the ink metering elements.
  • the color control system also includes command buttons "inking unit” 6 with which an inking unit of the printing press can be selected for the display and adjustment processes. As indicated in Fig.
  • the command buttons "inking unit” 6 consist of a plus and minus button by means of those on a display "inking unit” 6.1 the number of existing inking units can be counted up or down until the number of the desired inking unit appears.
  • the "inking unit” 6.1 can be configured, for example, as a light-emitting diode display.
  • the adjustment processes carried out in the individual ink metering zones via the "less color” or “more color” command buttons 4.1 - 4.n or 5.1 - 5.n are thus always carried out in the selected, current inking unit.
  • a pair of command buttons “lift strip” 7 is provided, by means of which the lift strip width can be adjusted as desired in the selected inking unit.
  • the command buttons "lifter strips” 7 are in turn designed as a plus-minus button pair.
  • a display "lift strip” 7.1 is provided, for example again as an LED display.
  • the color control system also includes a display device for displaying the color profile in the selected inking unit, which is designed, for example, as a row of light emitting diodes 8.1 - 8.n assigned to each color metering zone or as a screen device 9.
  • the positions of the ink metering elements relative to the ink fountain roller can thus be read from the number of light-emitting diodes on the rows of light-emitting diodes 8.1 - 8.n.
  • the color profile can represent the positions of the color metering elements of the selected inking unit, for example in the form of bars or as a line corresponding to the color profile.
  • a pair of "percent" 10 command buttons is also arranged on the color control panel, by means of which the positions of the color metering elements in the selected inking unit can be increased or decreased as a percentage with respect to their starting position.
  • This percentage adjustment ie the percentage value of the adjustment is shown numerically on a display 10.1.
  • the percentage adjustment can be adjusted across the entire width of the format, but it is also possible to limit the percentage adjustment only to a certain area. To mark such an area, the corresponding command buttons "less color” / "more color” 4.1 - 4.n / 5.1 -5.n of the color metering zones, which limit this area, are pressed simultaneously.
  • Such a simultaneous actuation of the corresponding keys can be detected and stored by means of a detection circuit associated with the operating device, in addition to memory, so that the percentage adjustment entered via the "percent" 10 command key only becomes effective in this area.
  • the area is deleted again by double-pressing the button pairs.
  • the color control system can be switched from a normal mode to a special mode and vice versa by simultaneously pressing both command buttons "percent" 10.
  • the rows of LEDs 8.1 - 8.n or the screen device 9 display the original color profile (normal mode) as well as the color profile now changed by the printer.
  • the printer can therefore temporarily supply more or less ink in certain ink metering zones in accordance with the printing-specific requirements and only restore the original color profile with one operation.
  • the printer can specifically adjust the correspondingly stronger or weaker ink supply to the requirements of the printing process. The risk that he increases or decreases the ink supply in certain metering zones, that is, achieves an undesired change in coloration on the printed sheet, is significantly reduced by this type of display of the color profile.
  • the original color guide (color profile) can only be called up at any point in time by a single operation. If the original position of the color metering elements, that is to say the original color profile, is to be restored, only both command buttons "percent" 10 are to be pressed again at the same time, whereupon the color metering elements of those zones in which an increased or reduced color supply has occurred are returned to their original (stored) values be reversed (switchover from special mode to normal mode).
  • the command buttons "percent” 10 are assigned a detection device 11, by means of which a double actuation of this operating element can be determined (FIG. 2).
  • the "Percent" 10 command button is pressed twice in normal mode, the positions of the Color metering elements of the selected inking unit are written into a memory 12.
  • the write command can be found in the state memory 11 '(normal, special mode).
  • the memory 12 receives the position values of the color metering elements by querying the control electronics 13 of the color metering elements, which receives the control commands via the command buttons "less color” / "more color” 4.1 - 4.n / 5.1 - 5.n and accordingly in setting commands for the Drives the color metering elements.
  • FIG. 3a) to c) show examples of the simultaneous display of the original color profile and the current color profile in special mode.
  • the starting position of a color metering element is represented by a corresponding number of switched on light emitting diodes 14 in the light emitting diode row 8.1 - 8.n.
  • the current position of the color metering element during the increased or reduced supply of color is indicated by a flashing light-emitting diode 14 of the same row of light-emitting diodes in this color metering zone.
  • FIG. 3b) the simultaneous display of the current and the original color profile is shown on the display device 9 by correspondingly different colored bars 15.
  • the color profile is given in a color unit by a closed line.
  • the current and original color profiles differ, for example by different colors or dashed lines or the like.
