  • a printing press with an intaglio printing unit with forme cylinder and impression cylinder is also known from EP 03 51 366 B1.
  • the gravure printing unit is in this printing press combined with an indirectly working printing unit, from which printed sheets with With the help of an intermediate sheet transport device.
  • Printing machines of this type allow printing on top of one another with different ones Techniques on the same substrate with a high degree of registration. she are therefore preferred for printing documents that have a high degree must be secure against counterfeiting, such as banknotes, securities, ID documents etc.
  • EP 08 64 421 A1 describes a printing press with exchangeable ones Ink application devices for different printing processes.
  • EP 05 63 007 A1 shows an intaglio printing machine on its plate cylinder in addition to the stencil cylinder attached to the cylinder Stencil cylinder is employed.
  • GB 511 049 A describes a printing press in which an engraved Plate cylinders are assigned to screen printing cylinders.
  • the invention has for its object to provide an intaglio printing machine.
  • the advantages that can be achieved with the invention are, in particular, that they are Print tactile features easily and with high registration accuracy in relation to other print motifs.
  • the attachment of such tactile motifs is particularly desirable for banknotes, in order to include a visually impaired person enable safe detection of banknotes and differentiation of their denominations.
  • the pressure plate of the forme cylinder of such a machine advantageously has Wells, which are not just wells for receiving one Ink can act, but also screen printing ink targeted in such depressions can be introduced to them subsequently with one of the shape of the recess to print the corresponding profile.
  • the gravure printing process carried out with the printing press is preferably a batch printing process, i. H. there is a collecting cylinder on which different inks to be printed independently of each other, preferably with the help of template cylinders, and so created complete gravure motif in a single slit passage on the Substrate is transferred.
  • the screen printing cylinder is on the forme cylinder arranged. In terms of the direction of production, it can be behind one for the Gravure printing device known per se can be arranged so that the Screen printing process takes place essentially unaffected by gravure printing.
  • screen printing cylinders can also be attached to the form cylinder before such Wiping device can be arranged so that the screen printing ink in a corresponding manner how to wipe the ink.
  • the screen printing cylinder is on the collecting cylinder arranged and applied the screen printing ink to this first.
  • the design of the printing press shown in schematic section in FIG. 1 has a plurality of inking units 8, each with a stencil cylinder 4 interact and color on raised areas of the assigned Transfer template cylinder 4.
  • the template cylinders 4 in turn act with one Collection cylinder 6 together, on which they receive the ink received by the inking units 8 transfer. In this way, a multicolored pattern is formed on the collecting cylinder 6 generated, the colored zones of each of the raised areas of the template cylinder 4 correspond.
  • the collecting cylinder 6 in turn acts with a forme cylinder 2, e.g. B. one Plate cylinder 2 together, on the gravure plates, in particular Steel line printing plates are mounted. These pressure plates are in contact with the Collection cylinder 6 colored according to the color pattern formed on the latter, the ink passing through the gap between plate cylinder 2 and Collecting cylinder 6 is essentially pressed into etched or engraved fine channels, that correspond to a detailed pattern to be printed on the substrate.
  • a forme cylinder 2 e.g. B. one Plate cylinder 2 together
  • the gravure plates in particular Steel line printing plates are mounted.
  • These pressure plates are in contact with the Collection cylinder 6 colored according to the color pattern formed on the latter, the ink passing through the gap between plate cylinder 2 and Collecting cylinder 6 is essentially pressed into etched or engraved fine channels, that correspond to a detailed pattern to be printed on the substrate.
  • the Wiper device 3 behind the gap is one Wiper device 3 arranged, those portions of the ink that are in the fine channels have
  • the printing machine thus generates a complete intermediate image on the plate cylinder 2, that contains all the colors of the image to be printed and in one Gap passage is transferred to the substrate.
  • This arrangement allows the Screen printing pattern with an extremely high degree of accuracy in relation to that Position rotogravure patterns on the printing plates and so one degree To achieve registration in two steps by promoting the Printing processes separate printing is not feasible.
  • one expediently becomes a screen printing ink with a high viscosity compared to that lying on the surface of the impression cylinder 1 Choose gravure ink to avoid being on the flat surfaces of the printing plates applied screen printing ink when passing through the gap 9 to an undesirable extent is flattened, which could lead to an unclean print image and the tactility of the screen print pattern on the finished printed product.
  • FIG. 2 differs from that of FIG. 1 by the arrangement of the screen printing cylinder 7 in the production direction behind the collecting cylinder 6 and in front of the Wiper device 3.
  • FIG. 3 shows a section of a pressure plate for use in this press. Their surface ranges between plan, not printing Areas 13 each have fine channels 11 and larger depressions 12. The channels 11 can cross the depressions 12. The channels 11 each serve to receive printing ink from the collecting cylinder 6, whereas the larger recesses 12 for receiving Screen printing ink are provided.
  • the wiper device 3 When passing through with printing and screen printing ink Colored plate cylinder 2 by the wiper device 3, the flat areas 13 of the printing plate freed of color, whereas in the channels 11 or depressions 12 the applied color remains and when passing through the gap 9 on the Substrate is transferred.
  • the screen printing cylinder 7 is in the production direction arranged in front of the collecting cylinder 6. This has happened when using a pressure plate As shown in FIG. 3, the consequence is that the depressions 12 have already been filled with screen printing ink when inking takes place. As a result, when applying the Screen printing ink on the printing plate in the recesses 12 no printing ink is a color alienation of the screen printing ink by printing ink on finished printed product largely excluded.
  • Fig. 5 shows a further embodiment of the printing press, which is different from the above described differs in that the screen printing cylinder 7 on the collecting cylinder 6 is arranged instead of on the plate cylinder 2. It can there, as shown in the figure, based on the direction of production in front of the template cylinder 4, or behind them be arranged. In this embodiment, too, the plate cylinder 2 passes through applied screen printing ink the wiper device 3, the effects and advantages of this Design therefore essentially correspond to those with regard to the Embodiments of FIGS. 2 and 4 have been described.
  • Fig. 6 shows in a partial section a structure of the screen printing cylinder 7, which in particular 1, 2 and 4, it is advantageous if the plate cylinder 2 Has circumferential areas that deviate from the exact cylinder shape, for. B. due from there arranged sheet grippers 21.
