Definitions

  • the invention relates to a device for controlling the automatic influencing of the coloring on printing presses using at least one color density measuring device, a device for target / actual value comparison, at least one electronic computer for linking the measured values with control values and devices for dosing the ink supply to the printing plate, consisting of Color metering elements with associated setting and feedback devices and displays for the actual position values of the color metering elements.
  • DE-AS 27 28 738 describes a device for checking and regulating the coloring on printing presses, in which the color control is carried out fully automatically by means of a composite system of microcomputers and the person is deliberately excluded as a delaying and - since in his judgment subjective - as a faulty part of the control loop becomes.
  • the valuable specialist knowledge and the experience of the printer acquired over many years is completely lost to the printing process, since there is no longer any possibility for the printer to intervene in the color control cycle to correct the quality. Even if due to a faulty color density measurement due to failure or contamination of the densitometer, e.g.
  • a control during the adjustment of the ink zone actuators is not available to the operator of the printing press, so that the subsequent signaling of sources of error results in a completely unnecessary delay in color optimization with macula Accuracy occurs despite automatic control and adversely affects the color quality of the printed product. Nevertheless, the presence of the operator can still not be carried out, since he has to monitor the supposedly automatic regulation of the coloring and react to error or alarm signals.
  • DE-AS 27 27 426 it is proposed in DE-AS 27 27 426 to provide a device for controlling the ink supply of a sheet-fed offset printing press with a display device for displaying the color density deviations from actual color density values measured on the printed product compared to predetermined color density target values, the color density deviations all ink zones are displayed simultaneously as a deviation profile that is connected across the entire width of the printed product.
  • the printer is given indirect reference values about the size and direction of the adjustment to be made as a recommendation, on the basis of which he can orient himself when adjusting the color control elements, whereby his personal assessment of the quality of the printed product based on visual assessment to form targeted, optimizing control interventions in the coloring and compensation of disturbance variables that cannot be measured are left with sufficient space.
  • the object of the invention is to create a device which deliberately involves the printer in the process of coloring and displays concrete reference values for the absolute travel of the ink zone actuators without having to forego the advantages of automatic coloring. and, on the one hand, monitoring the color density measured values as a supplement to the automatic density measured value recording and, on the other hand, also an immediate check during the adjustment of the ink zone actuators for predetermined position setpoints, ie total monitoring of the execution of the control commands - not only quantitatively but also qualitatively - immediately enabled.
  • this object is achieved in that guide displays assigned to the ink metering elements are provided for representing manipulated variables of all ink actuators in each printing unit, which give the operator precise recommendations for guiding the ink actuators to predetermined setpoint position values and give them their absolute adjustment paths both in Signalize size and direction and that a guide device selectable by the operator for tracking the ink actuators is coupled individually or at least one printing unit to the guide displays.
  • Such a device guarantees the fastest possible color optimization of the printed product with a minimum of waste, since the manipulated variables - already implemented in absolute travel of the ink actuators - are displayed precisely before they are updated.
  • the printer does not have to do without the advantages of automatic color control, he always has the opportunity to bring his experience into the printing process.
  • the displays of the actual position values of the ink zone metering elements and / or the guide displays of the manipulated variables of all ink zone actuators can optionally be switched to color density trend displays, the same display means being provided for all three displays are.
  • the guide displays are additionally designed to reproduce the actuating movements of the color actuators. Only through the direct visual representation of the actuating movements is there direct monitoring and absolute control already during the tracking of the color actuators regarding uncompleted or incomplete execution of actuating commands.
  • the values of the target positions of the ink zone actuators are transformed to a common reference line in the guide displays and the actual positions of the ink zone actuators in the form of a tracking profile by means of the leading lighting elements as Position deviations from the values of the target positions of the reference line can be represented.
  • Position deviations from the values of the target positions of the reference line can be represented.
  • the color density measuring device be equipped with a device for releasing measured values, for releasing and forwarding both the color density measurement data after their checking and acceptance by the operator and predetermined color density target values to the positioning device.
  • a device for releasing measured values for releasing and forwarding both the color density measurement data after their checking and acceptance by the operator and predetermined color density target values to the positioning device.
  • a device In order to consciously exclude individual or several ink zone actuators in individual or several printing units from a tracking and to carry them out separately - if necessary, taking into account locally occurring errors in the color quality that are not always ascertainable due to a color density measurement that is spatially limited to a print control strip - a device is optional Locking and unlocking of ink zones are provided, by means of which any ink zone actuators, one or more printing units in each case, can be deliberately excluded from the tracking control or the automatic tracking system and released again for this, the manual tracking by means of the remote control being retained.
  • the printer has the freedom of choice between a tracking control for one-time tracking of the ink zone actuators, an automatic tracking system for continuous, automatic tracking of the inking zone actuators or a remote control for manual tracking of individual inking zone actuators, so that he thereby has the advantages of fully automatic control with a human experience enriched can combine manual control.
