  • FIG Fig. 1 to 3 described in more detail, although using the example of measuring areas that are outside of a subject as pressure control elements. It should be noted that the invention can also be used analogously for measuring ranges that lie within a subject.
  • Fig. 1 and 2 show an inking unit 10 embodied as a lifting inking unit of an offset printing press, wherein the inking unit 10 comprises a fountain roller 11 which receives printing ink held ready in an ink fountain 12. With the ductor roller 11, a lifting roller 13 cooperates, wherein the lifting roller 13 receives from the ink fountain roller 11 printing ink in the form of a so-called lift strip and intermittently in the direction of arrow 14 to one of the lifting roller 13 downstream inking roller 15 transfers.

  • the amount of ink that is transferred from the ink fountain 12 to the ink fountain roller 11 depends on a zonal coloring of a subject to be printed. As Fig. 2 can be removed, the color box 12 so-called Farbzonenstellelemente 28 are assigned, wherein on the Farbzonenstellelemente 28 which per color zone on the ink fountain roller 11 transmitted amount of color is adjustable.

  • the ink slide and the squeegee roller are part of a so-called Farbdosier adopted the inking unit.
  • inking unit 10 is preferably used in sheet-fed offset printing presses.
  • inking units are used which, instead of color slides, comprise colorimeters as color zone setting elements and, instead of the lifting roller, a so-called film roller.
  • Fig. 3 schematically shows a substrate 29, which is printed with aof 30 and outside of the subject 30 with pressure control elements 31, wherein the pressure control elements 31 are printed outside the actual subject 30 in the form of a control strip 32 on the substrate 29.

  • a print control element 31 is printed on the printing substrate 29 outside the subject 30, wherein a peripheral strip 34 covered by the print control element 31 is smaller or narrower than the peripheral strip covered by the respective color zone 33.
  • the pressure control elements 31 printed outside of the subject 30 are measured densitometrically and / or colorimetrically and / or spectrally and actual values determined here are compared with predetermined setpoint values in a control device in order to depend on the comparison between the actual values obtained by measuring the pressure control elements 31 and the predetermined setpoint values To generate control signals for the Farbzonenstellelemente 28 for automatically controlling the zonal coloring of the subject 30.
  • control deviations are modified both on the basis of data of the subject and on the basis of a model of the respective inking unit.
  • digital pre-press data is used, either as low-resolution PPF or JDF format data or as high-resolution image data.
  • the high-resolution image data are preferably so-called bitmaps of the individual color separations, which are usually used for the production of printing forms.
  • the model of the inking unit which is used to modify deviations, depends on the rolling behavior and, if necessary, traversing behavior of the rollers of the inking unit.
  • the model of the inking unit can also incorporate data about the materials used in the inking unit as well as the dynamic behavior of the inking unit.
  • At least one print control element 31, which is printed on the printing substrate 29 outside the subject 30, is measured, wherein a peripheral strip 34 covered by the print control element 31 is smaller or narrower than one covered by the respective color zone 33 Is circumferential strip.
  • a coverage value is determined from the data of the subject, which are preferably provided from a digital pre-press, for the coverage area covered by the print control element 31, a coverage value. If this areal coverage value determined from the data of the subject is smaller than a predefined limit value, then in accordance with the present invention the predetermined setpoint value for the corresponding color zone setting element is increased or the measured actual value is reduced.
  • the target value for the corresponding inking zone actuator is increased by an amount X, which is from the data
  • the area coverage value determined for the subject varies between 0.5% and 2%, so the setpoint can be increased by an amount Y, the amount Y being smaller than the amount X. If, however, the area coverage value determined for the circumferential strip covered by the print control element is greater than 2%, no increase in the reference value takes place.
  • the peripheral strip covered by the pressure control element can be subdivided into a plurality of sub-strips, wherein an area coverage value is determined for each of the sub-strips from the data of the subject. It is then possible to use an averaging of the area coverage values of these sub-strips to modify the control deviation between the setpoint and the actual value. Alternatively, only the areal coverage value of that sub-stripe can be used to adapt the setpoint value and / or the actual value and thus to modify the control deviation between the setpoint value and the actual value within which a measurement area of the pressure control element lies.
  • a traversing behavior of at least one roller of the inking unit is known from the inking unit model of the inking unit, according to a further advantageous development of the invention not only is the area coverage covered by the printing control member determined from the180 data, but such areal coverage values are also determined for adjacent circumferential bands , Preferably, for a plurality of adjacent circumferential stripes, corresponding areal coverage values are determined from the data of the subject, wherein in the change of the desired value and / or the actual value of the circumferential strip covered by the control element, more distant circumferential stripes are weighted less heavily than closer circumferential stripes.
  • a so-called drop in color is determined depending on the model of the respective inking unit.
  • a drop in color usually sets in when the rolling on the forme cylinder Ink rollers can not apply printing ink on the printing form due to a clamping channel for a printing plate. If it is determined from the inking unit model that a pressure control element is affected by such a drop in color, a modification of the control deviation between the measured setpoint and the preset actual value also takes place.
  • the predetermined target value for the corresponding ink zone actuating element is increased or the measured actual value is reduced. If, on the other hand, there is a minimum of the ink drop in the peripheral strip covered by the pressure control element, then the predetermined desired value for the corresponding ink fountain element is reduced or the measured actual value is increased.
  • a surface coverage value dependent on the stenciling behavior of the inking unit is determined from the data of the subject and from the model of the inking unit for a circumferential strip covered by the print control element. If this area-coverage value, which depends on the patterning behavior, is greater than a predefined limit value, then the specified target value for the corresponding ink-zone setting element is reduced or the measured actual value is increased in the sense of the present invention.
  • the procedure is as follows, that for the circumference strip covered by the pressure control element, a surface coverage value is determined, which is a development length of a application roller in front of the peripheral strip covered by the pressure control element.
  • a respective unwinding length of these rollers is determined in front of the circumference strip covered by the pressure control element, a corresponding areal coverage value. If the area coverage determined in this case is greater than a predefined limit value, preferably the predefined setpoint value for the corresponding ink zone setting element is reduced.
  • the effect can be taken into account that when the covered by the pressure control element perimeter strip a circumferential length of a inking roller from a perimeter strip with high area coverage is removed, the pressure control element displays a lower color density, since such a strong decrease in color after a rollover of the inking roller not yet complete can be compensated.
  • a method for controlling the color scheme in which system deviations between actual values and predetermined setpoint values acquired at print control elements printed outside the actual subject are modified depending on data of the subject as well as on an inking unit model.
  • effects such as the inking unit, the drop in color and the fact that a covered by a pressure control element perimeter strip is smaller than a covered by the respective color zone perimeter strip, bill be taken into account.
  • the color can be optimized significantly during printing.
