Definitions

  • the invention relates to a method for ascertaining an actuating signal for ink-zone actuating elements of an inking unit or for dampening-agent metering devices of a dampening unit of a printing press according to the preamble of claim 1.
  • a printing unit of a printing press has a forme cylinder, a transfer cylinder, an inking unit and a dampening unit. At least one printing plate is positioned on the forme cylinder, it being possible with the aid of the inking unit to apply printing ink and, with the aid of the dampening unit, fountain solution to the or each printing plate positioned on the forme cylinder.
  • the printing ink is transferred to a transfer cylinder, namely at least one transfer mold positioned on the transfer cylinder, wherein the transfer cylinder ultimately applies the printing ink to a printing material to be printed.
  • a printing unit is also referred to as an offset printing unit.
  • the forme cylinder is also referred to as a plate cylinder and the transfer cylinder as a rubber cylinder.
  • the dampening unit of such a printing unit has a storage container for dampening solution, wherein the storage tank dampening agent metering devices are assigned.
  • the dampening agent metering devices can be designed, for example, as diaphragms or as spraying devices.
  • the dampening agent metering devices associated with the storage container are positioned next to one another in the axial direction, with the number of dampening agent metering devices juxtaposed in the axial direction usually corresponding to the number of printed pages to be printed next to one another on the printing substrate by means of the printing unit in the axial direction. Accordingly, in the case of printing units known from practice, the dampening unit of the printing unit usually has a dampening agent metering device for each printing side to be printed side by side on the printing substrate, viewed in the axial direction.
  • a printing machine control station of a printing press includes controls for inputting commands to the ink zone actuators of an inking unit or dampening dosing devices of a dampening system to either adjust or further open the same, and ultimately to adjust the amount of ink or dampening solution to be transferred.
  • the actuating elements of the printing machine control station for the ink zone setting elements and the dampening agent dosing devices are assigned to printing material-side color areas or wet areas.
  • the Farbzonenstellelemente or Moisture dosing devices are associated with printing machine side ink zones or wet zones.
  • the present invention has the object to provide a novel method for determining a control signal for Farbzonenstellelemente an inking unit or for dampening dosing of a dampening unit.
  • a control signal for at least one Farbzonenstellelement or at least generates a dampening agent metering device based on the actuation of an actuating element, depending on the format of the printing 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 material in the printing press, a control signal for at least one Farbzonenstellelement or at least generates a dampening agent metering device.
  • a method for determining a control signal for Farbzonenstellelemente an inking unit or dampening dosing of a dampening unit is proposed for the first time, with which even when the printing material, in particular the width of a substrate to be printed changes, upon actuation of a christmaschinenleitstand feature actuator optimum adjustment of the inking zone actuating elements or of the dampening agent metering devices is carried out.
  • a relative position of the printing material side color ranges or wet areas to the printing machine side ink zones or wet zones is generated.
  • the present invention relates to a method for determining a control signal for Farbzonenstellelemente an inking unit or for dampening dosing of a dampening unit, hereinafter referred to with reference to Fig. 1 and 2 the invention is described for the case that a control signal for Farbzonenstellelemente an inking unit is determined.
  • Fig. 1 shows a section of a printing substrate 10 to be printed in the region of a printing page 11 of the printing substrate 10.
  • a printed image is to be printed, wherein the printed image of the printing side 11 of several color areas 12 composed.
  • Fig. 1 By way of example, six such color regions 12 of the printing side 11 arranged next to one another in the axial direction are shown.
  • a control panel 13 of a printing machine control station has a plurality of operating elements for the ink-side color areas 12, namely a first operating element 14 for increasing the zonal coloration and a second operating element 15 for reducing the coloration in the respective ink-side color area 12.
  • an actuating signal for ink-zone actuating elements 16 of an inking unit 17 is finally generated, wherein the ink-zone actuating elements 16 are not assigned to the ink-side color regions 12 of the printing material 10 but rather to ink-side ink zones 16.
  • Fig. 2 shows that a printing material 18 is to be printed, which has a different printing material format or printed page format seen in the axial direction or in width, there is no more 1: 1 assignment between the ink side ink areas 12 and the ink fountain 16 provided by the Farbzonenstellelemente 16 color zones.
  • a christmaschinenleitstand feature actuator 14 and 15 is based on the operation of a christmaschinenleitstand featureen actuator 14 and 15 and depending on the format of the substrate to be printed and / or depending on the format of printed material to be printed on the printed pages and / or depending on the axial position of the printing material in the printing press, namely in the printing unit, and / or depending on the geometric arrangement or the axial width of the Farbzonenstellelemente 16 and / or depending on the axial range of action of the actuated actuator 14 and 15 generates a control signal for at least one Farbzonenstellelement 16.
  • the format of the substrate to be considered is the axial width of the substrate and the format to be taken into consideration for print pages to be printed on the substrate is the axial width of the printed pages.
  • the axial position of the printing substrate in the printing unit depends on the web guide or on the web path of the printing material web to be printed within the printing unit.
  • a relative position of the ink-side color areas is determined to the ink engine side ink zones.
  • an actuating signal for at least one ink zone actuating element 16 is then generated on the basis of the actuation of an actuating element.
  • a 100% corresponding actuation of an actuating element 14 to 30% on a first Farbzonenstellelement 16 and 70% on an adjacent Farbzonenstellelement 16 is divided. This percentage distribution is dependent on the relative position between the ink-side color areas to the ink side color zones.
  • the determination of the actuating signal for at least one ink zone actuating element is furthermore dependent on a traversing movement of at least one inking roller of the inking unit.
  • the method according to the invention can also be used for determining actuating signals for dampening agent metering devices, such as diaphragms or spraying devices of a dampening unit.
