Definitions

  • the invention relates to a method for determining presetting parameters for an inking unit of a printing unit of a printing press according to the preamble of claim 1.
  • An inking unit of a printing unit of a printing press has an ink fountain and a cooperating with the ink fountain duct roller, which is held in the ink fountain ink, depending on the opening position of the ink fountain associated Farbzonenstellelementen that are designed as a color meter or ink slide, starting from the ink fountain on the Ductor roller passes.
  • the ductor roller is arranged downstream of a lifting roller or a film roller, with inking units of sheet-fed printing presses of the ductor roller typically being followed by a lifting roller and, in the case of inking units, a roller printing machine of the ductor roller, typically a film roller.
  • An inking unit also has several inking rollers that roll on a forme cylinder of the printing unit and apply ink to at least one positioned on the forme cylinder printing form. Between the squeegee roller or film roller and the inking rollers a plurality of inking rollers are positioned to promote the ink in the direction of the inking rollers, wherein at least one of these inking rollers is designed as a distributor roller, which, seen in the axial direction of the distributor roller performs a so-called traversing movement.
  • the presetting parameters for the ink zone setting elements and the squeegee roller or film roller are determined such that a defined area coverage is provided at the beginning of printing in each color zone.
  • This related art is for example from the DE 33 38 143 C2 , of the DE 44 36 953 C1 as well as from the DE 10 2004 043 372 A1 known.
  • the present invention has the object to provide a novel method for determining Voreinstellparametern for an inking unit of a printing unit of a printing press.
  • This object is achieved by a method according to claim 1.
  • the preset parameter of the respective ink zone setting element is varied for each ink zone, taking into account fixed pre-setting parameters of the or each distributor roll and taking into account the coverage of at least one adjacent ink zone such that a defined, desired ink quantity or ink layer thickness is provided for each stationary ink state.
  • the invention is based on the finding that the print quality, which can be provided directly with recording of the printing operation, can be increased by taking into account the traversing movement of the distributor rollers and the area coverage of adjacent ink zones in the determination of the presetting parameters for the ink zone setting elements.
  • Fig. 1 shows a schematic representation of an inking unit 10 of a printing unit of a printing machine, in particular a sheet-fed press, wherein the inking unit 10 of Fig. 1 a plurality of inking rollers 11 which roll on a plate cylinder 12 of the inking unit 10 comprehensive printing unit to apply ink to at least one positioned on the forme cylinder 12 printing form.
  • the inking 10 of Fig. 1 In addition to the inking rollers 11 further includes a color box 13 and a cooperating with the ink fountain roller duct 13 13.
  • the color box 13 Farbzonenstellelemente are assigned, which are referred to as a color slider or color meter, depending on the Position of Farbzonenstellelemente ink removed from the ink fountain 13 and per ink zone is applied to the ductor roller 14.
  • the inking rollers 16 in the illustrated embodiment are so-called distributor rollers which execute a so-called traversing movement in the axial direction thereof.
  • the inking rollers 17 do not perform such traversing movement, are therefore seen fixed in the axial direction of the same.
  • Fig. 2 shows a subject 18, which is to be printed on the printing unit comprising the inking unit 10, wherein the subject 18 is seen in the axial direction in the already mentioned, several color zones 19 is divided.
  • a preset value for the ink zone setting element of the respective ink zone 19 can be determined from the pre-setting data of the ink fountain 10 to be printed so as to define a defined area coverage per each of the ink zones 19 at the start of printing in each of the ink zones 19 To provide color zone 19.
  • presetting parameters for the ink zone setting elements of the ink zones 19 but also presetting parameters for the squeegee roller 15, such as a squeeze stroke of the same, are determined.
  • This determination of the presetting parameters for the ink zone setting elements and the squeegee roller 15 on the basis of prepress data of the subject 18 to be printed is already state of the art and therefore familiar to the person skilled in the art.
  • an individual start of transfer and thus a start of offset offset and / or an individual transfer stroke and thus a Verreibungshub offset to the or any other distributor roller 16 are fixed.
  • the presetting parameter of the respective ink zone actuator is varied for each ink zone 19 such that, for a steady state taking into account the traversing movement of the distributor rollers 16 in FIG each color zone 19 is provided a defined, desired amount of ink or ink layer thickness.
  • the position and the number of adjacent color zones to be taken into account for each ink zone 19 is determined as a function of the predetermined transfer stroke of the distributor rollers 16.
  • the presetting parameters determined according to the invention for the ink-zone setting elements of the inking zone 19 can be displayed on a control station of a printing press, which must then be taken over by a printer for the printing operation.
  • the print quality that can be achieved directly at the start of printing and thus recording of a print job can be increased. This can further reduce the printing of waste.
