  • Fig. 1 In the lower part of the picture, a newspaper double page with its lateral widths b S and the associated operating elements B j or virtual zones Z V, j with the virtual zone widths b V is shown schematically.
  • the virtual zone widths b V applicable to the pages placed on the console correspond to the physical zone width b P at the inking unit and the number of virtual zones Z V, j per printed page S to the number of effective physical zones Z P, j .

  • Fig. 2 schematically is a printing unit 01 and a control station 07 with a respect to the machine Fig. 1 smaller product format and a smaller machine width M2 shown.
  • the forme cylinder 02 for example, several, compared to the machine Fig. 1 narrower printing forms arranged side by side.

  • the ink fountain 04 has metering elements D i or physical zones Z P, i with a zone width b P of the physical zones Z P, i or of the metering elements D that is different from the zone width b V of the virtual zones Z V, j j up.
  • the virtual dividedness of the zones Z V, j (at the control station 07 or the prepress) related to the printing page width (or the machine width M1, M2) is different from the physical parting of the zones Z related to the printing page width (or the machine width M1, M2) P, i at the Farbdosier sensible 04.

  • the difference of divisions of the physical and virtual zones Z P, i , Z V, j can also exist in a different spatial position relative to the printed page S. In the present case, the differences in the division exist with regard to the number and position of the zones Z P, i , Z V, j .
  • the inking unit or the metering device 04 can, as in Fig. 2 shown more than the number of absolutely necessary dosing D i have or only as many dosing D m , as to fully cover the effective width b e , ie the present machine width M2 required (in this case the Fig. 2 seven per side, six are not enough).
  • M1 the same metering device 04 are used, in the second case for different widths of the metering device 04 at least the same metering D i .
  • the virtual, a pressure side strips associated zone Z V, 3 so carried by the algorithm A such a conversion that the drive of the dosing D 4 is controlled.
  • the size of the actuating signal it is advantageous to take into account the size of the overlap or overlap between the position and width of the virtual and physical zones Z V, 3 and Z P, 4 . Since the physical zone Z P, 4 is wider here than the associated virtual zone Z V, 3 , the required real change of the gap width is smaller than the virtually requested change.
  • the conversion is carried out such that a plurality of metering D i (here the two D 4 and D 3 ) - advantageously taking into account their coverage - positioned accordingly or their drives are controlled accordingly.
  • the same principle of the conversion lies with the or an algorithm of a presetting system 08 (or the Pre-printing) on which the presetting values for the physical zones Z P, i are to be formed from the otherwise standardized standardized integer-coordinated zones.
  • the presetting system 08 or in the prepress, the actual physical zones Z P, i already are taken into account in the calculation of the presetting values from the required area coverage or color densities and stored there in the corresponding programs.
  • a metering device 04 is shown, wherein the width b P of the physical zones Z P, i here is smaller than the width b V of the virtual zones Z V, j at the control station 07 or in the default settings of Vorereinstellsystems. That to the FIGS. 1 and 2 explained is here to apply in the same way. Virtual and physical (effective) parts of the zones Z V, j , Z P, i are again different from each other.
  • the algorithm A ensures that upon selection of a specific virtual zone Z V, j, a corresponding transfer to the relevant metering element D i or to the corresponding metering elements D i (or their drive / drives) takes place.
  • the physical division here is an integer, in this case nine, but could also differ from an integer-based on the printing page width or the effective width b e of the ink metering device 04.
  • the virtual division (number of zones Z V, j or controls B j per print page S) is an integer and amounts to eight.
  • the ink metering device 04 has such a number m of metering elements D i that the widths b P of the zones in total are greater than or equal to the machine width M1; M2 or maximum web width.
  • the width of the ink metering device 04 is then executed accordingly.
  • dosing elements D i lying in edge regions of the ink metering 04 outside the effective width b e it can be provided in the algorithm A and or in the machine or pilot control that these metering elements D i are generally controlled to closed gap.
  • the ink metering device 04 then has such a number m of metering elements D i that the widths b P of the zones Z P, i in total are greater than or equal to the machine width M1; M2 is, however, a (m + 1) th metering element D m + 1 completely outside the effective width b e or outside the projection of the machine width M1; M2 would lie.
  • the control station 07 is thus continued as usual with an integer, advantageously even number n of (virtual) zones Z V, j or with the corresponding number m of controls B j (eg n pairs of buttons B j ), while the Paint metering 04 is formed with a different division of these zones Z P, i standardized width b P and possibly different number m.
  • the format and / or number and / or zone-width-dependent shifts between virtual and physical zones Z V, J , Z P, i are converted and taken into account via the algorithm A-in particular computer-aided. For this purpose, corresponding computing means containing the algorithm are provided.
  • the algorithm A may have a function among other things of the machine width M1 defined by the maximum web width; M2 and / or the number m of the physical zones Z P , i or the metering elements D m and / or the number n of the virtual zones Z V, j or the controls B j and / or a width b P of the physical zones Z P, i be.
