Definitions

  • the invention relates to a method for printing printed sheets in a sheet-fed printing machine according to the preamble of claim 1.
  • the invention further relates to a sheet-fed printing press according to the preamble of claim 4.
  • a sheet-fed press typically has a feeder, multiple printing units and a boom. With the help of the investor to be printed sheets are introduced into the sheet-fed press and fed to the printing units, wherein in each printing unit, a partial printing image is applied in a defined ink on the sheet. Printed sheets are ejected from the sheetfed press in the area of the jib.
  • the benefits are automatically distributed over the format of the printed sheets to be printed with the help of a prepress device while minimizing nonprinted sheet areas, for which purpose a so-called imposition program is implemented in the prepress stage.
  • imposition program it is possible to automatically distribute the benefits over the format of the print sheets to be printed, and, as already mentioned, to make optimum use of the size of the print sheets while minimizing non-printed sheet areas.
  • At least one print control strip which continuous bar at one edge section the signature extends over the entire width thereof.
  • Such a print control strip is measured according to the prior art outside the printing press and therefore offline for printing the printed sheets. Actual values determined here are then used to control or regulate the coloring on the printed sheet.
  • the present invention is based on the problem to provide a novel method for printing sheets in a sheet-fed press and a corresponding sheet-fed press.
  • This problem is solved by a method according to claim 1.
  • the or each print control strip is automatically subdivided into a plurality of sections by the pre-press device, wherein the individual sections of the or each print control strip are automatically placed with the pre-press device over the format of the print sheets to be printed in those print sheet areas which are not printed for use in printing; the coordinates of each individual section of the or each print control strip, together with coordinates of at least one signature reference point, are automatically communicated to a measuring device incorporated in the sheetfed press, and wherein the signatures based on the provided coordinates inline for printing thereof at least in the area of printed on the or each Print control strip are measured automatically.
  • the subdivision of the or each print control strip into individual sections and by the placement of the same over the entire format of the sheets can be achieved over the entire sheet format consistent coloration.
  • the subdivision of the or each print control strip into sections as well as the placement of the sections on the format of the press sheets is automated with the prepress device, preferably with the aid of the imposition program implemented in the prepress device.
  • the coordinates of each individual section of the or each print control strip are automatically transmitted together with coordinates of at least one signature reference point from the pre-press device to a built-in sheetfed press measuring device, so that the measuring device inline to print the sheet can automatically measure the sections of the or each print control strip.
  • the method according to the invention permits a high degree of automation, without a printer operating on the printing machine having to perform a teach-in on a measuring device.
  • the method according to the invention therefore runs automatically and thus ensures a high degree of production reliability. Through automation, incorrect entries of a printer can be avoided.
  • Fig. 1 shows a highly schematic representation of a sheet-fed press 10, which comprises a feeder 11, a plurality of printing units 12 and a boom 13.
  • a sheet-fed press 10 which comprises a feeder 11, a plurality of printing units 12 and a boom 13.
  • the investor 11 to be printed sheets are kept ready, which are fed to the first printing unit 12 by means of the investor 11, to be printed sheets are successively transported through the individual printing units 12 so as to print in each of the printing units 12 a partial image on the print Apply printing sheet.
  • the jib 13 printed printed sheets are discharged from the sheet-fed printing machine 10. Details of the investor 11, the printing units 12 and the cantilever 13 are familiar to the person skilled in the art and need no further explanation.
  • Fig. 2 shows an example of a printed sheet 14, wherein on the sheet 14 several benefits 15 are printed. These benefits 15 may be z. B. trade in packaging or labels.
  • An optimal distribution of the benefits 15 over the entire format of the printed sheets 14 takes place with the aid of a pre-printing device 16, in particular with the aid of an imposition program implemented in the pre-press device 16.
  • the benefits 15 are distributed over the entire format of the printed sheets 14 in such a way that unprinted printed sheet areas of the printed sheets 14 are minimized.
  • each print control strip is automatically subdivided into a plurality of sections 17 by means of the pre-press device 16, wherein the individual sections 17 of the or each print control strip are automatically placed over the entire format of the print sheets to be printed 14 in such print sheet areas using the pre-press device 16, which are not printed with benefits 15 when printing.
  • portions 17 of a print control strip are shown as black bars distributed throughout the format of the signature in those portions thereof that are not printed with utility.
  • horizontal width of the sheet 14 are the individual sections 17 of the print control strip distributed over the format of the sheet 14 that seen in the horizontal direction, the individual sections 17 do not overlap, but in addition, over the entire 15 printed with benefits, horizontal width of the sheet 14 extend.
  • the subdivision of the or each print control strip into the individual sections 17 and the placement thereof over the entire format of the print sheets to be printed is carried out automatically by means of the pre-printing device 16, the coordinates of each individual section 17 together with coordinates of at least one signature reference point 18, 19 are transmitted to an integrated into the sheet-fed press 10 measuring device 20.
  • the measuring device 20 measures the printed sheets 14 inline for printing on the basis of the coordinates provided by the pre-printing device 16 at least in the area of the printed on the sheet 14 sections 17 of the or each print control strip.
  • the coordinates and thus the positioning of the print control strips 17 on the printed sheet 14 of the built-in sheet-fed printing machine 10 measuring device 20 is thus automatically provided by the pre-printing device 16 so that no manual teach-in for the measuring device 20 is required.
  • the coordinates of two printed sheet reference points 18 and 19 of the measuring device 20 are provided, wherein the sheet reference point 19 is a reference point of the printed sheet 14 lying in the middle of the horizontal width. Coordinates of the printing sheet reference points 18, 19 are automatically determined by the pre-printing device 16.
  • the automatic division of a print control strip into a plurality of sections 17 and the distribution of the sections 17 over the format of the printed sheets 14 is such that the prepress device 16, preferably the imposing program implemented therein, first determines the coordinates of the signature reference points 18 and 19, then the the print control strip to be split is then automatically selected, taking into account the distribution of the benefits 15 over the printed sheets 14 into individual sections 17 and the individual sections 17 over the entire format, so both the width and the height of the sheet, distributed and in such areas placed, which are not printed with utility 15. These coordinates are automatically transmitted to the measuring device 20 integrated in the sheet-fed printing press 10, so that the measuring device 20 can automatically measure the printed sheets 14 in the region of the sections 17 without requiring teach-in, namely online for printing on the printed sheets 14.
  • Measurements obtained from surveying the sections 17 may be used to control or regulate the coloration on the signature.
