Definitions

  • the invention relates to a method for preparing a printing unit for printing, which comprises at least one inking unit with an anilox roller interacting with a doctor blade, which can be coated with an interchangeable screen jacket provided with ink-guiding cups, which is driven by the forme cylinder speed and whose diameter in the operational state is equal to the diameter of the a printing forme plate and a printing unit suitable for carrying out the method.
  • an inking unit with an anilox roller is known, the cells of which are arranged in a compressible carrier layer, which can also be designed as an exchangeable plate.
  • a compressible carrier layer which can also be designed as an exchangeable plate.
  • EP 0 279 295 A2 shows a printing unit for offset or high-pressure machines, in which an application roller with a resilient surface is arranged between an anilox roller and the forme cylinder, the diameter of which is equal to the diameter of the forme cylinder covered with a printing forme and which is driven at the forme cylinder speed.
  • No. 4,672,893 deals with a mixed printing process, wherein an ink fountain cylinder is provided with an engraved image area and an anilox ink metering area.
  • a cylinder attached to the ink fountain cylinder is equipped with a blanket transfer area and a flexographic image area.
  • the images of the engraved image area and the flexo image area are printed in one or more stations in order to create an overall design on a flexible plastic.
  • the invention has for its object to provide a method and a device suitable for its implementation, with an exact dosage of the ink to be fed to the forme cylinder, both in the circumferential direction and in the longitudinal direction of the anilox roller with little wear on the parts is made possible.
  • the forme cylinder 2 interacts with an inking roller 4, which has a resilient ink-accepting surface.
  • the ink is applied to the inking roller 4 by an anilox roller 5.
  • a grid jacket 6, designed as a grid plate, is clamped onto the anilox roller 5.
  • the diameter of the screen roller 5 covered with the screen jacket 6 is equal to the diameter of the ready-to-use forme cylinder 2.
  • the forme cylinder 2 and the rollers 4, 5 are driven at the same speed.
  • the inking roller 4 also has the same diameter.
  • the plate forming the grid jacket 6 is made of a hard material with a flat surface into which wells are introduced.
  • a gravure winding plate as shown in detail in FIGS. 3 and 5, is used as the grid jacket 6.
  • a chamber doctor blade 7 is employed, with which ink is simultaneously fed to the anilox roller 5 and then its surface is doctored off becomes.
  • a dampening unit 8 of any type, indicated only schematically, is provided, with which dampening solution can be applied to the forme cylinder 2.
  • an impression cylinder 9 is provided with which a printing material web 10 is pressed onto the blanket cylinder 1.
  • the impression cylinder 9 can be the blanket cylinder of another printing unit.
  • Fig. 2 shows that the printing form 3 has a plurality of printing areas 11, 12, 13, between which non-printing areas remain. If the printing form according to FIG. 2 is to be used for printing, a grid jacket 6 according to FIG. 3 is produced, which is provided with ink-receiving areas 14, 15, 16, between which ink-repellent areas lie.
  • the printing form 3 and the screen jacket 6 are clamped onto the forme cylinder 2 or the screen roller 5.
  • the grid jacket 6 is clamped in such a way that the ink picked up by the area 14 is passed on via the inking roller 4 to the printing area 11 of the printing form 3.
  • the ink picked up by the areas 15, 16 is guided via the inking roller 4 to the areas 12, 13 of the printing form 3.
  • the ink-receiving areas of the grid jacket 6 are formed by cells 17 which are introduced into a photopolymer layer 18.
  • the photopolymer layer 18 is firmly connected to a carrier layer 19.
  • each ink-guiding cup of the screen jacket 20 guides an ink particle over the inking roller 4 to a point on the printing form 3 where this ink particle is required immediately.
  • a screen printing plate can be used as a grid jacket 21.
  • cups 22 are provided, which go through the entire thickness of the screen printing plate. The bottom of these cups 22 is formed by the surface of the anilox roller 5.
  • the application of the method according to the invention is not limited to offset printing units.
  • a forme cylinder 23 is provided which can be covered with hard high-pressure molds 24.
  • the ink is in turn fed to the forme cylinder 23 by means of an applicator roller 25 with a resilient, ink-accepting surface.
  • the application roller 25 is in contact with an anilox roller 26, on which a raster jacket 27 is applied, which is provided with cells only in the printing areas.
  • the grid jacket 27 is designed as an exchangeable sleeve.
  • a chambered doctor blade 28 is provided for ink supply. However, any other known doctor blade inking unit can also be used for the ink supply.
  • the forme cylinder 23, the anilox roller 26 and the applicator roller 25 have the same diameter and are driven at the same speed.
  • the grid jacket 27 is produced with a well configuration that is either tailored only in some areas or precisely to the color requirements of the high-pressure mold 24.
  • the printing form and screen jacket are then clamped onto the forme cylinder 23 or the screen roller 26.
  • the method according to the invention can also be used in flexographic printing units.
  • the printing form and the screen jacket are applied to the forme cylinder or the screen roller that is in direct contact with it.
  • the main advantage of the invention can be seen in the fact that any additional adjustment or control means can be used to adapt the ink conveyed by the anilox roller to the ink requirement of the forme cylinder, both in the circumferential and in the lateral direction. Since the cups of the grid jacket can be produced in different depths, this can be adapted to the color to be used in each case.
