Description

The invention relates to a method for operating a printing press according to the preamble of claim 1.

When printing a substrate, in particular at least one substrate web, in a printing machine, in particular a web-fed rotary printing press, ink fountain units designed as ink slides or ink knobs in inking units of printing units of the printing machine are set to wet zone control elements and optionally in dampening units of the printing units of the printing press designed as damp screens or spray nozzles to provide a desired printed image on the substrate to be printed. It is already known to display the setting of Farbzonenstellelementen and / or the setting of Feuchtzonenstellelementen column-like or beam-like on a control station monitor a printing press control system.

To change a printed image printed on the substrate, it is also already known to influence the setting of Farbzonenstellelementen and / or the setting of Feuchtzonenstellelementen the control room of the press control system, but it is difficult, the Farbzonenstellelemente and / or the Feuchtzonestellelemente the corresponding areas of the printed image assigned. In particular, this is the case when margins of a printed product do not coincide or coincide with limits of the actuating elements. Therefore, there is a risk that a printer will alter the setting of a wrong color zone setting element and / or the setting of a wrong wet zone setting element, thus changing the printed image in an undesirable manner.

On this basis, the invention has the object to provide a novel method for operating a printing press. This object is achieved by a method according to claim 1. In the method according to the invention, the adjustment of Farbzonenstellelementen and / or the setting of Feuchtzonenstellelementen is displayed on the monitor together with the print image such that columns or bars to display the setting of printing-side ink zone actuators and / or display the setting of printing wet side zonal elements and / or Display of the color density are displayed in the areas of the printed image, for which with the respective Farbzonenstellelementen and / or Feuchtzonestellelementen a printing ink quantity and / or a dampening solution amount is set.

With the method according to the invention, it is proposed for the first time to display the bars or columns which visualize the current settings of ink zone setting elements and / or the current settings of wet zone positioning elements, together with a print image to be printed on a monitor, namely such that the columns or bars in FIG the corresponding areas of the printed image are superimposed, for which a printing ink quantity and / or a dampening solution quantity is set with the respective ink zone setting elements and / or wet zone setting elements. As a result, it is always known to a printer which color zone setting element and / or wet zone setting element is assigned to which area or section of the printed image, so that incorrect operation of ink zone setting elements and / or wet zone positioning elements can be reliably avoided.

Preferably, the columns or bars for indicating the setting of Farbzonenstellelementen and / or of Feuchtzonestellelementen in the areas of the Solldruckbilds are displayed as the setting of the ink zone actuators and / or Feuchtzonenstellelemente act on the areas of the printed image or determine the printed image in these areas ,

Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawings. Showing:

Fig. 1:

a schematic representation of a monitor display to illustrate the method according to the invention.

The present invention relates to a method for operating a printing press, in particular a web-fed printing press. For printing on a printing material, in particular at least one printing material web, color zone adjusting elements designed as ink slides or inking knives are set in inking units of printing units of the printing press such that a desired printed image is printed on the printing material to be printed.

Then, when the printing units comprise dampening units, wet zone positioning elements, which are also designed as damp screens or spray nozzles, are set in dampening units in order to print the desired printed image on the printing material to be printed.

The adjustment of Farbzonenstellelementen and / or the setting of Feuchtzonenstellelementen is displayed on a monitor of a press control system, in particular on a control console monitor. So shows Fig. 1 highly schematized visualized on a control panel display 10, wherein on the control room monitor according to Fig. 1 Settings of Farbzonenstellelementen in the form of columns 11 are displayed. Horizontal lines 12 provide an orientation within the ink zone actuator positioning range.

According to Fig. 1 For example, the setting of the ink zone adjustment elements on the monitor 10 is displayed together with the print image, with Fig. 1 Print images 13, 14 of two printed pages are displayed together with the setting of the Farbzonenstellelemente visualizing columns 11.

The columns 11 for indicating the setting of the ink fountain key elements are in this case in the respective printed images 13, 14 faded in, namely such that the columns 11 are inserted into such areas of the printed images 13, 14, for the respective Farbzonenstellelementen and / or Feuchtzonestellelementen a printing ink quantity is set.

Accordingly, the bars 11 come exactly into the area of the respective print image 13 or 14, for which the coloration of the corresponding print image area can be set with the corresponding ink zone setting element. Accordingly, it is immediately apparent to a printer which color zone setting element is associated with which area of a print image 13 or 14 to be printed, so that the printer can reliably change the coloring of the corresponding print image area by selecting this inking zone setting element. In each case, the print image that is printable with the respective settings of the ink zone setting elements and / or the wet zone control elements is displayed as a print image.

Target image may be a target image of a newspaper printing product or a target image of a sheet-fed printing product or a section of a newspaper printing product or a sheet-fed printing product.

The bars 11 for indicating the setting of the corresponding ink-zone actuating elements are inserted into the areas of the print image 13 or 14, as the adjustment of the ink zone actuating elements act on the areas of the print image 13 and 14 or determine the printed image 13 or 14 in these areas ,

The beams 11 preferably have a normalized width. Vertical boundary lines adjacent to the bars 11 may indicate the real width of the corresponding ink zone actuators or the range of action thereof resulting from a driver roller influence. The action areas can also be visualized by curves running between these vertical boundary lines. Also, the width of the beams 11 can be adapted to the action of the Farbzonenstellelemente dependent on the distributor roller influence.

According to Fig. 1 are further displayed in the display 10 of the monitor in the form of dash-dotted lines shown vertical color lines 15 Farbkastenabschnittsgrenzen or color box separations in the printed image displayed on the monitor. Also, vertical lines can be displayed to represent printing plate boundaries.

Furthermore, in the form of vertically extending, dashed lines shown 16 dampener boundaries in the printed image. In the Fig. 1 are, as already stated, displayed in the print image bars 11, which indicate the setting of Farbzonenstellelementen.

The representation of the bars can be carried out in full color with complete coverage of the areas of the printed image or preferably transparent, showing through the areas of the printed image. From the bars, only frames or boundary lines can be displayed.

In the case of Farbzonenstellelementen the frame of the bars can be represented in each influenceable with the Farbzonenstellelement ink. Furthermore, it is possible to show the color densities resulting from the settings of the ink zone setting elements for the areas of the print image. This is particularly advantageous when connecting a color control system.

In contrast, it is also possible to show bars that represent the setting of Feuchtzonenstellelementen. Furthermore, bars for visualizing the setting of ink-zone actuators can be displayed simultaneously on the monitor with columns for visualizing the setting of wet-zone actuators in print images.

The simultaneous fading in of the beams or columns for the ink zone control elements and the beams or columns for the wet zone control elements can be done without overlapping the same geometrically one above the other or with the same overlap.

The above display preferably takes place on a monitor in the form of a touch screen, wherein the adjustment of the ink fountain control elements directly or indirectly and / or the wet zone control elements can be changed by touching the bars or columns 11 on the touch screen. Indirect adjustment of the ink zone controls means adjustment of the ink zone controls via the color density.

Furthermore, it is possible, on the basis of actuations made on a printing machine control unit, which are associated with inking areas or wet areas, for the ink zone actuators and / or wet zone actuators associated with inking zones, particularly depending on the format of the substrate to be printed and / or depending on the format of print pages to be printed on the substrate and / or depending on the axial position of the printing substrate in the printing press, to calculate the bars for the ink zone positioning elements and / or the wet zone positioning elements.

This makes it possible, according to the percentage distribution of an uniquely assigned to an area on the printed product actuating element on the corresponding Farbzonenstellelement or Feuchtzonenstellelement the positions of the Farbzonenstellelemente and / or Feuchtzonenstellelemente back to a printed product-related area and print product related the calculated values in the form of bars in the Solldruckbild , This is advantageous when connecting a color control system for displaying the color density.
