Definitions

  • the invention relates to a sheet-fed or roll multicolor rotary printing machine for simultaneous face and reverse printing, in particular for printing the security background on securities, especially banknotes, according to the preamble of patent claim 1.
  • Such a printing machine is known from EP-A-0 132 859 in the form of a convertible machine, with which by means of appropriate adjustment of the cylinders either an offset print or a color collective print, in which an image with adjacent colors is produced, can be produced.
  • the image is printed using the corresponding bulk printing plate in the form of a high-pressure plate which has the complete printing pattern and is installed on one of the plate cylinders mentioned.
  • This high-pressure plate is inked by an ink collecting cylinder, which is formed by a rubber cylinder and in turn receives the colors from several ink selection rollers, the number of which corresponds to the number of colors of an image to be printed.
  • the multicolor image is transferred from the colored printing plate to the relevant rubber cylinder. When the printing gap between the two rubber cylinders is passed, the paper is printed on both sides simultaneously with a multicolor image.
  • the arrangement is such that the two ink collecting cylinders are practically to the side of the rubber cylinders assigned to them and are only slightly offset relative to them.
  • This arrangement of the four large cylinders means that the machine needs a lot, as seen perpendicular to the cylinder axes a lot of space, since the dimensions of the inking unit frames on both sides practically add a length four times a cylinder diameter.
  • the colors on each of the ink collecting cylinders are transferred to the plate cylinder carrying the collecting printing plate by means of a special intermediate cylinder in order to take account of the directions of rotation of the cylinders which are necessary because of the convertibility of the machine.
  • double inking of the printing plates with the aid of two image transfer cylinders is provided. All these last-mentioned cylinders, plate cylinders, intermediate cylinders and image transfer cylinders are provided on the undersides of the rubber cylinders and the ink collecting cylinders and take up practically the entire space below these four large cylinders.
  • an additional offset printing unit preferably a wet offset printing unit, is provided in this known perfecting machine, the plate cylinder of which is in contact with one of the blanket cylinders.
  • a multicolored security background can be produced in a single operation using the collective printing process and at the same time a single-colored main pattern using the offset printing process.
  • the object of the present invention is to improve a printing machine of the type described above in such a way that all parts of the machine, with the smallest possible overall dimensions, are more accessible, so that the setting up and maintenance of the printing machine is made considerably easier.
  • the only Figure 1 shows schematically the embodiment of a sheet printing machine.
  • the sheet printing machine shown has an input device supplying the paper 1 in sheet form, which is equipped with a stop drum 2, transfer drums 3 provided with grippers and with a paper dedusting and antistatic device 3 'installed on both sides of the paper 1'.
  • the sheets are transferred to a rubber cylinder 4 provided with grippers, which cooperates with a further rubber cylinder 14 which has the same diameter.
  • the sheets run between the two blanket cylinders 4 and 14 and are printed on both sides at the same time.
  • the cylinders rotate in the directions indicated by arrows. After printing, the sheets are transported by a chain gripper system 24 to a delivery stack or, if appropriate, to a machine that completes the printing.
  • the machine is composed of two symmetrical halves.
  • Each blanket cylinder 4 and 14 is in contact with a plate cylinder 5 and 15, which is arranged on its lower circumferential region and which has a collecting printing plate 5a or 15a in the form of a high-pressure plate.
  • Each of the ink collecting cylinders 6, 16, which are rubber cylinders, works in the example under consideration with four ink selection rollers 8 and 18, which have cut-out reliefs 8a and 18a according to the contour of the areas to be printed in the respective color.
  • Each ink selection roller 8, 18 is inked in this color by means of an inking unit 9 or 19.
  • the two upper inking units each have a color box, all other inking units each have a double ink box.
  • All inking units 9 are located on a removable inking unit frame 12, all inking units 19 on a removable inking unit frame 22.
  • the color selection rollers 8, 18 are preferably made of a hard material which does not run the risk of preforming, even if the relief is very fine, so that a security background composed of very fine lines can be obtained.
  • the area of the four colors is transferred from the ink selection rollers 8 and 18 to the ink collecting cylinder 6 and 16, on which they are combined and by which they are applied to the respective one Collective printing plate 5a and 15a of the plate cylinder 5 and 15 are transferred.
  • This collective printing plate 5a and 15a represents the complete printing pattern to be printed in the four colors, in particular a security background in each case.
  • the two complete patterns colored with the different colors are in turn transferred to the rubber cylinders 4 and 14, respectively.
  • An automatic blanket washing device 7, 17 is installed below each blanket cylinder 4, 14 and each ink collecting cylinder 6, 16, with which the blankets in question can be washed when there is no printing operation and which, of course, have moved away from these cylinders during the printing operation.
  • At least one additional printing unit is provided, the plate cylinder of which cooperates with one of the blanket cylinders 4, 14 and works according to a printing method other than the collective printing method.
  • each of the two blanket cylinders 4 and 14 is in contact with the wet offset plate cylinders 10 and 20, each with a wet offset printing unit that is equipped with its own inking unit 11 or 21 and with a dampening unit 11a or 21a.
  • An intaglio printing plate, the non-printing surface of which is made ink-repellent by moistening, is preferably used as the wet offset printing plate.
  • the one inking unit 11 and the dampening unit 11a are installed on an inking unit frame 13, which is attached to the top of the removable inking unit frame 12 and is moved together with it; the other inking unit 21 and the dampening unit 21a are installed on an inking unit frame 23, which on the Top of the removable inking frame 22 is attached and moved together with it.
  • the blanket cylinders 4, 14 transfer the multicolor collective printing patterns which they receive from the printing plates 5a and 15a of the plate cylinders 5 and 15, and at the same time the monochrome images originating from the plate cylinders 10 and 20 of the wet offset printing units, respectively, to the two sides of the paper Images that can overlay the multicolored collective print pattern.
  • these images produced by the wet offset printing units are preferably both a main pattern of the banknote and an additional security background, the generally fine lines of which overlay the multicolored security background generated by the collective printing process and therefore a particularly high level of security for the banknote produced lend against counterfeiting.
  • a banknote is printed completely on both sides, each with a multicolored security background and a single-color main pattern, the security background consisting of a four-color collective printing pattern and a superimposed one, there is an additional single-color security background pattern, which, like the main pattern, is produced in wet offset printing.
  • more than one additional printing unit interacting with each of the blanket cylinders 4 and 14 can of course also be provided be, for example, two or even three printing units.
  • these printing units can also work with dry offset or conventional wet offset printing plates.
  • the diameter of the rubber cylinders 4 and 14 and the ink collecting cylinders 6 and 16 is an integral multiple, in the example considered three times the diameter of the ink selection rollers 8 and 18 and the plate cylinders 5, 15, 10 and 20.
  • the plane that goes through the axes of the cylinders 6 and 4 intersects the plane going through the axes of the cylinders 16 and 14 above the rubber cylinders 4, 14 at an angle, which in the example considered is about 60 °, so that the free space between the ink collecting cylinders 6 and 16 in this case corresponds to almost 1.5 times the cylinder diameter.
  • the angle mentioned can be between 40 ° and 120 °, preferably between 50 and 70 °.
  • the printing machine according to the invention can also be a web printing machine, in which case the sheet guiding elements are then merely replaced by the known guiding elements for a paper web.
