Definitions

  • the invention relates to a sheet-fed offset printing machine with anilox coloring in unit construction.
  • Printing machines with anilox coloring of the printing form so-called flexographic printing machines, are usually designed as roller machines known; Flexographic printing machines in the form of sheet flexographic printing machines are not common.
  • a sheetflex flexographic printing press in web-like construction is known (flexographic printing from A to Z; Polygraph Verlag Frankfurt am Main; page 100), which is constructed analogously to the web printing press principle.
  • the sheet to be printed is guided horizontally by means of sheet guiding elements designed as transport rollers through the printing zone of the impression cylinder and printing form cylinder, with a sheet alignment taking place in each printing unit in this transport principle.
  • each printing unit for the use of low-viscosity printing inks contains an anilox roller assigned to the printing form cylinder as well as a rubber roller that is operatively connected to the anilox roller and a doctor device assigned to the anilox roller.
  • Conventional sheet-fed offset printing presses in unit construction consist of sheet guiding elements, ink guiding elements as well as a sheet feeder and a sheet delivery.
  • the sheet guiding elements of the conventional sheet-fed offset printing presses in the form of aggregates contain printing cylinders and transfer drums arranged in aggregated substructures and, if necessary, reversing drums for the realization of perfecting.
  • the ink guide elements of the conventional sheetfed offset printing presses in unit design contain in aggregated conventional printing towers, which are placed on the aggregated substructures, each arranged an offset cylinder, a printing form cylinder, an inking unit and a dampening unit, the inking unit being designed as a roller inking unit for processing highly viscous offset printing inks.
  • Sheet-fed offset printing machines of the aforementioned type cannot be used as flexographic printing machines.
  • the object of the invention is to provide a sheetfed offset printing machine with anilox coloring in aggregate construction.
  • the drawing shows a sheet-fed offset printing machine according to the invention in a unit construction with anilox coloring.
  • the sheetfed offset printing press consists of a sheet feeder 1, a sheet guide 2 and a sheet delivery 3 as well as several anilox printing towers 4 and a conventional printing tower 15.
  • the sheet guide 2 is used to transport sheets and consists of printing cylinders 5 and transfer drums 6.
  • a printing cylinder 5 and a transfer drum 6 are each arranged in an aggregated substructure 7, with the printing cylinder 5 and transfer drum 6 having the same diameter.
  • Printing cylinders 5 and transfer drums 6 preferably have twice the diameter in relation to the offset cylinder 8 and the printing form cylinder 9.
  • the number of transfer drums between two printing cylinders, the size ratios of printing cylinders and transfer drums to each other or relative to the cylinders of the printing towers, and the design of the transfer drums as perfect and reverse printing drums can vary depending on the design of the sheet-fed offset printing press from the embodiment shown, the basic principle being aggregated Substructures for sheet guidance with printing cylinders and transfer drums - is the same and is subsumed under the term substructure 7 of a conventional sheetfed offset printing machine. Each aggregated substructure 7 is assigned an aggregated printing tower 4 or 15, the substructure and printing tower each forming a printing unit.
  • a conventional printing tower 15 is understood to mean a conventional printing tower of a sheet-fed offset printing machine with offset cylinder, printing form cylinder and inking and dampening unit, the inking unit being designed as a roller inking unit.
  • the anilox printing tower 4 contains an offset cylinder 8 which is operatively connected to the printing cylinder 5 and a printing form cylinder 9 which is operatively connected to the offset cylinder 8.
  • This cylinder arrangement described corresponds to the cylinder arrangement in a conventional printing tower 15 of a sheetfed offset printing press.
  • An inking system 10 working on an anilox basis is assigned to the printing form cylinder 9.
  • This inking system consists of an applicator roller 11 which is operatively connected to the printing form cylinder 9.
  • the application roller 11 is designed to be printing plate cylinder-sized in order to achieve freedom from stenciling and is preferably an offset cylinder, ie a cylinder with a stretched rubber blanket.
  • the application roller 11 is assigned an anilox roller 12 with a doctor blade 13, also referred to as anilox roller.
  • a dampening unit 14 can additionally be assigned to the printing form cylinder 9 or the printing form cylinder 9 and the application roller 11. To realize different scooping volumes of the anilox roller, the same is arranged interchangeably.
  • the machine design is identical to the machine design of a conventional sheetfed offset printing machine, which results in lower production costs for the machine. Furthermore, it is possible to use the devices integrated in conventional sheetfed offset presses - perfecting, drying, etc. - for sheetfed offset printing with anilox coloring.
  • the advantages of the machine design according to the invention lie in the elimination of an ink zone adjustment, the avoidance of side effects due to slapping and axial rubbing, the complete freedom from stenciling and the lowest amount of waste.
  • offset printing with anilox coloring is possible.
  • anilox dry offset is also possible.
