Definitions

  • the invention relates to a method for handling printing plates on a web press in a printing plate change.
  • printing plates To perform a printing plate change printing plates must be handled in the area of a web press. It is important that when a plate change is made, each plate is fed to the correct printing unit of the correct printing unit of a web press, and that each plate is clamped within the correct printing unit at the correct plate cylinder position on the plate cylinder of the printing unit.
  • the printing plates In web-fed presses with a manual printing plate change, the printing plates are manually held ready at the plate cylinder positions of the printing units of a web-fed printing press by a printer.
  • printing presses with an automated printing plate change the printing plates are provided at the plate cylinder positions of the printing units of the printing units of a web-fed printing press with the aid of printing plate carriers, which serve as printing plate stores.
  • the printing plates kept ready in the printing plate carriers can be automatically removed by means of a manipulator arm from the printing plate carriers and automatically fed to the plate cylinders of the printing units.
  • the present invention has the object to provide a novel method for handling printing plates.
  • the present invention it is proposed for the first time to automatically position unexposed blank panels in the printing plate supports, in which also the exposed printing plates are arranged for an automated printing plate change. This makes it possible to hold unexposed blank plates together with the exposed printing plates on the printing plate support together and therefore automated at the corresponding plate cylinder positions. As a result, the degree of automation in the printing plate change can be increased.
  • the present invention relates to a method for handling printing plates on a web-fed printing press in an automated printing plate change.
  • Fig. 1 highly schematically schematized the handling of printing plates in an automated printing plate change, wherein in an imagesetter 10 printing plate blanks 11 exposed and fed after exposure from the imagesetter 10 a Abkant worn 12 tonostikanten the printing plates.
  • the exposure of the printing plate blanks 11 in the imagesetter 10 is based on a production scheme and on the basis of prepress data, wherein the prepress data is rasterized in a raster image processor and wherein the production scheme is provided by a production planning device.
  • a control device controls the imagesetter 10 on the basis of the screened prepress data and on the basis of the production scheme in order to carry out the exposure of the printing plate blanks 11.
  • the bending of the printing plates in the Abkant Anlagen 12 is a mechanical operation to form the leaded printing plates bevelled leading and trailing ends. Leading and trailing ends are required for clamping the leading and trailing ends on the plate cylinder or forme cylinder of a printing unit.
  • the exposed in the imagesetter 10 and folded in the Abkant gear 12 printing plates are automatically positioned depending on the production scheme in printing plate supports 13, wherein the equipped with printing plates printing plate support 13 are transported to the printing plate change in the area of the printing unit of a printing unit of a web printing press on which the printing plates needed for printing plate change become.
  • the transport of the printing plate carrier 13 in the region of the corresponding printing unit is preferably carried out automatically, but can also be done manually.
  • the removal of the exposed printing plates from the printing plate supports 13 for carrying out a printing plate change is preferably carried out automatically by means of a handling device or a manipulator arm.
  • uncoated printing plate blanks 14 are used for the blank plates, they need not pass through the imagesetter or the developer.
  • blank plate coated platings 14 they need not pass through the imagesetter but the developer to remove the coating therefrom. However, this is more expensive, so that uncoated printing plate blanks 14 are preferably used for the dummy plates.
  • Fig. 2 shows that the dummy plates and printing plates are folded in different Abkant sexualen, according to Fig. 2 for the printing plate blanks 14 of the blank panels a separate Abkant sexual 15 is present.
  • the printing plates and blanking plates are automatically positioned in the printing plate supports 13 starting from the folding devices 12, 15.
  • the automated positioning of the beveled printing plates and beveled blanking plates in the printing plate supports 13 is done so that the printing plates and blanking plates are positioned at positions within the printing plate supports 13 that correspond to the plate cylinder positions where they are needed for automated printing plate changing, depending on the production scheme.
  • the encoding is either an optically readable barcode or text code or a non-contact readable RFID tag or to a mechanically readable coding such.
  • B. may be a punched.
  • the coding of the printing plate support 13 then provides information about at what position within the respective printing plate support 13 which pressure plate or blank plate is arranged.
