Definitions

  • the invention relates to a printing cylinder for printing machines, in particular offset printing machines.
  • duplication is known in sheet rotation. This means a stretching of the halftone dot or the appearance of a double dot in the printed image. The print becomes full and out of focus. The point can duplicate on all sides depending on the cause. The same applies to parts of writing and drawings.
  • Various causes are responsible for duplication in the sheet rotation. For example, wrong handling, a rubber blanket that is too loose, wrong direction of the rubber blanket, a rubber blank that is too long, loose clamping strips of the rubber blanket, a moving plate cylinder, loosened grippers, corrugated dented paper or paper with different force-elongation behavior, electrostatically charged paper and a pressure cylinder, the surface of which is not clean, ie is smeared by paint residues, rust and the like.
  • the object of the invention is to provide a printing cylinder for printing machines, e.g. To create offset printing machines, the sheet-guiding surface of which prevents different expansions of the paper and on this basis also the point shift in the printed image.
  • a jacket surface consisting of a metallic material, preferably copper, is effective against duplication if a wrinkled-grain screen structure 3 with a screen fineness between 12 and 50 lines / cm is etched into the metallic jacket surface.
  • the production can be carried out, for example, in a manner comparable to the production of a gravure etching of gravure cylinders or gravure plates.
  • the jacket surface can be a direct component of the printing cylinder or it can also be a plate, film or the like, which is glued or stretched onto the printing cylinder.
  • an additional coating with a wear-resistant material e.g. a chrome coating is provided.
  • the latter also works against smearing, since it is color-repellent. This is of particular importance on an impression cylinder of an offset printing unit.
  • the jacket surface according to the invention is thus suitable as the surface of sheet guiding cylinders, printing cylinders in straight printing and printing cylinders in reverse printing.
  • the pressure cylinder 1 shown schematically in FIG. 1 is provided with a jacket surface 2, which according to FIG. 2 has a relief or a structure 3 in section, which consists of cup-like depressions 4, which are etched directly between grid bars 5 of a wrinkle grid Mantle surface 2 of the impression cylinder 1 or in a post-tensioned or glued onto the impression cylinder 1 Plate or the like.
  • the screen fineness of the wrinkled screen structure 3 is 12 to 50 lines / cm depending on whether cardboard or thin paper is being processed.
  • the coarser structure of 12 lines / cm is suitable for cardboard, while the finer structure of 30 to 50 lines / cm is suitable for thin paper.
  • the jacket surface 2 consisting of copper, after the wrinkled grain pattern 3 has been deeply etched into the jacket surface 2, is coated with a wear-resistant material, preferably with chrome.
  • a structured surface 2 of the printing cylinder 1 prevents duplication and / or smearing of freshly printed sheets on sheet-guiding cylinders, since movement of the paper on the surface of the printing cylinder 1 is prevented, while at the same time preventing the structured surface from being marked in the printed image because the jacket surface 2 according to the invention forms a uniform base for the entire printed image.
  • the printing cylinder jacket surface 2 according to the invention is produced on a plate, an elevator, a film or the like, which is subsequently to be glued on or clamped onto the printing cylinder 1, the method steps mentioned under 1 to 3 can be omitted. Individual process steps can also be replaced by equivalent steps, e.g. Imprint a corresponding random structure before etching.
  • the production method alternatively also includes the stamping, engraving of metallic copper jacket surfaces 2 or the washing out of plastic surfaces. Details not mentioned, e.g. Process parameters correspond to the known gravure etching of gravure cylinders or rotogravure plates. The same applies to the other mentioned methods for producing a jacket surface 2 with the wrinkled grain grid structure 3 according to the invention.
  • the gripper pad in the channel of the printing cylinder 1 is indicated by 6.
