Definitions

  • the invention relates to a device for transferring imaging layers from a carrier film to printing sheet according to the preamble of patent claim 1.
  • a printing material and a printing apparatus using this material are described.
  • a sheet-processing machine which has a feeder and a boom, wherein printing units and a coating module are arranged between the two units.
  • an adhesive pattern is applied by means of the planographic printing process. This adhesive pattern is applied in a cold printing process and has a specific imaging subject.
  • a film guide is provided in the printing unit following the coating module with a counter-pressure cylinder and a press roller.
  • the transfer film has a carrier layer on which imaging layers such as metallic layers, for example of aluminum, can be applied. Between the metallic layer and the carrier film, a separating layer is provided, which ensures that the metallic layer can be removed from the carrier layer.
  • each sheet is given an adhesive pattern. Thereafter, the sheet is passed through the coating module, being brought by means of the press roller on the impression cylinder resting sheet with the film material in combination. In this case, the downwardly lying metallic layer enters into a close connection with the areas provided with adhesive on the printed sheet.
  • the metallic layer adheres only in the area provided with the adhesive pattern.
  • the carrier film is thus removed from the metallic layer in the region of the adhesive pattern.
  • transfer film is wound up again.
  • the print sheet is laid out in the coated state. It is known to use such coating modules, for example in printing units of printing presses. A disadvantage of the known devices is that they can not be used flexibly.
  • the object of the invention is therefore to provide a device by means of which the transfer of an imaging layer, e.g. a metallization layer can be done on a sheet safely, economically and accurately, the device should be manageable for an extended range of applications.
  • an imaging layer e.g. a metallization layer
  • a printing press becomes more flexible in its application in that a film transfer module is integrated.
  • the film transfer module can be implemented as part of a print engine, as a separate workstation, as an integrated workstation, or as a workstation that can be moved.
  • the application is carried out in conjunction with various printing processes.
  • advantageous effects are achieved by the integration of gravure printing unit or a sheet-fed offset printing press and a sheet-fed gravure printing machine.
  • the film transfer module can be arranged at different locations within a printing press depending on the application. Therefore, it is also advantageously possible to provide a plurality of coating modules within a sheet-processing machine in a row.
  • the application of different imaging coatings or metallization layers within a subject can take place one after the other. In this case, it is possible to transmit the imaging layers next to one another using a single adhesive pattern with all the image pattern elements.
  • first adhesive pattern in a first coating module with a first image-forming coating or metallization layer and, in the following, to apply another, the first enclosing adhesive pattern and to provide it with another image-forming coating or metallization layer.
  • the film transfer module in a sheet-fed printing machine can also be arranged downstream of a device for the use of a sheet, so that an image-wise coating of the film transfer takes place on a sheet backside after previous front side printing
  • the image-forming layer can be applied by means of what is known as UV negative-pressure ink, by means of a printing unit for the adhesive in e.g. is applied over an offset printing plate.
  • FIG. 1 is a sheet-processing machine, here a printing press, shown, which consists of at least two printing units.
  • a sheet to be coated is provided in an applicator 1 with an adhesive imaging pattern.
  • the application of the adhesive takes place in offset printing by means of inking and dampening 11, a printing plate on a plate cylinder 12, a blanket or blanket cylinder 13 and a counter-pressure cylinder 4.
  • applicators in the form of flexographic printing units or coating units can be used.
  • a variant of such an embodiment is in Fig. 4 is shown.
  • the adhesive is transferred there by means of a dosing system 21 via an anilox roller 22 and a transfer roller 23 to a forme cylinder 24. This carries in this case a high pressure plate for generating the imaging adhesive application.
  • a transfer film 5 is passed through a transfer nip 6, wherein the transfer film 5 is pressed against the printing sheet in the transfer nip 6, thereby transferring an image-forming layer to the printing sheet in the region of the adhesive image.
  • the transfer nip 6 in the coating module 2 is formed by a press roll 3 and an impression cylinder 4.
  • a web guide for transfer films 5 is shown within the coating module 2 used for the film transfer.
  • a film supply roll 8 is assigned to the coating module 2 on the sheet feed side.
  • the film supply roll 8 has a rotary drive 7. The rotary drive 7 is required for the continuous controlled feeding of the transfer film 5 to the coating module 2 and is therefore controllable.
  • guide devices 14 are provided in the region of the film supply and removal, so that the transfer film 5 is guided without distortion and in the same Stress against the press roller 3 can be maintained. In this way, the film feed in the area of the coating unit 2 surrounding Verschept 15 is simplified.
  • the transfer film 5 is substantially tangentially past the press roller 3 or this only in a small circumferential angle to the press nip 6 and discharged.
  • the transfer film 5 is supplied from one side of the coating module 2 and discharged to the opposite side of the coating module 2.
  • a film collecting roller 9 On the outlet side of the printing unit, a film collecting roller 9 is shown, which rewinds the used film material. Again, a rotary drive 7 is provided, which is controllable.
  • the press roll 3 is provided with a press fabric 10 or as a roll with a corresponding coating, which is preferably smooth.
  • the imagewise applied adhesive layer can be predried by means of a first dryer 16 (intermediate dryer I), so that the wear layer of the transfer film 5 adheres better.
  • the adhesive effect of the applied wear layer on the printed sheet can be improved by the action of a second dryer 16 (intermediate dryer II) by additionally accelerating the drying of the adhesive.
  • the quality of the coating can be controlled by means of an inspection or monitoring device 17 after the foil application.
  • the inspection device 17 is directed to a sheet-guiding surface of the coating module 2 after the transfer nip 6 and optionally sealed off from the dryer 16 or on a sheet-guiding surface of the coating module 2 downstream further sheet leading module.
  • a gravure printing unit which is an integrated film transfer module for film transfer for use in a sheet-processing machine, such as a printing press.
  • the coating module 2 is designed integrated into a gravure printing unit.
  • the application of adhesive takes place in the gravure printing unit operated by the first gravure inking unit TF, to which the signature is fed from a sheet feeder.
  • the film transfer takes place from the film web of the transfer film 5 via the press roll 3, which can be covered with a rubber blanket.
  • the coated printing sheet can continue to be dried before being printed on the coating in another gravure printing unit.
  • the sheet transport cylinders and gravure cylinders are also suitable for further processing of the printed sheets.
  • Such a device can be used in a paint module of a sheet-fed printing press, which already has all the necessary elements in its basic design.
  • a chamber doctor blade system can be used instead of supplying the adhesive metering lacquer via the anilox roller and the forme cylinder, e.g. be used by means of a recessed blanket or a flexographic printing on the substrate.
  • the coating module 2 is essentially suitable for providing a printed sheet before printing with an imaging layer, for example a metallization layer.
  • an imaging layer for example a metallization layer.
  • the coating module 2 can also be placed at any other location within the machine. This is to make it possible that the desired imaging layers, such as metallization layers, before, as well as after and between the application of Ink layers can be done.
  • the coating module is designed as a transportable unit.
  • FIGS. 3 to 6 Various combinations of the assignment of coating modules 2 and applicators 1 are shown schematically for a printing press.
  • FIG. 3 basically shows a conventional configuration.
  • a sheet feeder AN of the sheet-fed printing machine is initially followed by an applicator 1 and then a coating module 2.
  • the coating module 2 is again followed by printing units D of the sheet-fed printing machine.
  • a bow boom AU completes the configuration.
  • an imagewise coating with metallized film can take place on the empty printed sheet.
  • a multicolored printed image can be applied over this coating.
  • a full-surface coating with metallized film can be produced, which can subsequently be overprinted in the printing units D.
  • a coating module 2 can also be subordinated to the printing units D in front of the sheet delivery AU, wherein the printing unit D upstream of the coating module 2 can serve as a commissioning unit 1.
  • the printing unit D upstream of the coating module 2 can serve as a commissioning unit 1.
  • FIG. 4 shows a similar configuration as FIG. 3 ,
  • both a coating module 2 and an associated application unit 1 are arranged within a work unit (see also FIG FIG. 2 ).
  • the image-wise application of two different, next to each other, but possibly cross-over coatings are made.
  • the arrangement of an integrated coating module IM is particularly useful if at least two film transfer modules are to be arranged directly one after the other.
  • the film transfer module is designed here as an attachment module AM.
  • Such an attachment module AM is preferably designed as a transportable unit and can be placed on a standardized substructure UB of a printing unit D of the printing press.
  • a substructure UB normally includes a frame in which a sheet transport drum and an impression cylinder 4 are associated with each other.
  • a printing blanket cylinder 13 of an offset printing unit or a forme cylinder 20 of a lacquer module can each be assigned to the impression cylinder 4 on the substructure.
  • the blanket cylinder 13 or forme cylinder 20 can be used in conjunction with the coating module 2 as a press roller 3, wherein a corresponding fabric 10 is to be attached.
  • Corresponding clamping devices are available on both cylinder types.
  • FIG. 6 is an advanced version shown.
  • the printing press shown has, after two printing units D connected to the sheet feeder AN, a so-called turning device W.
  • Turning devices W serve to invert a single-sided printed or coated printed sheet during sheet-fed operation of a sheet-fed printing press, so that its previous underside becomes the upper side, which can subsequently be printed or coated.
  • the applicator 1 and a coating module 2 adjoin the turning device W. Thereafter, if necessary, several further printing units D are provided up to the sheet delivery AU.
  • each printed sheet can first be printed on its reverse side in one or two colors, then turned over, then image-coated with a metallized layer and subsequently printed again in multiple colors.
  • An application example of this are greeting cards with jewelery inserts made of metal foil on the image page.
