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.
  • 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 unit, wherein by means of the pressing cylinder of the resting on the impression cylinder sheet is brought into contact with the sheet material. 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 units, for example in printing units of printing presses. It is also known to use as a pressing cylinder about the blanket cylinder or the blanket cylinder of a printing unit.
  • the object of the invention is therefore to provide a device with which a secure and economical transfer of imaging layers, e.g. Metallization layers can be done exactly and should be easy to handle.
  • imaging layers e.g. Metallization layers
  • an adhesive layer is provided by means of variably configurable applicators.
  • the application of the method in a variety of sheet-processing machines is possible.
  • existing coating compositions are utilized according to the invention.
  • the commissioned work can also have a short inking unit which is provided with an anilox inking device.
  • a film transfer device is provided according to the principle of cold foil transfer.
  • the coating unit can be easily placed at arbitrary locations.
  • both the applicator according to the invention and the coating unit are designed in the manner of a module as a transportable unit.
  • first adhesive pattern in a first coating unit 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 printing unit in the form of a coating unit used for this purpose a commissioned work is provided, which serves for applying the adhesive and is configured as a printing unit or coating unit.
  • the printing unit may be a conventional printing unit in the form of an offset printing unit or high-pressure unit. It can also be designed as a so-called anilox printing unit.
  • a short inking unit with screen roller technology is arranged in the printing unit, which is preferably used for the adhesive application.
  • the commissioned work can be provided with a paint supply device.
  • a paint supply device for this purpose, already known cartridge systems with replaceable ink containers or stationary ink supply devices can be used. This adhesive or ink can be assigned variable to the commissioned work.
  • the film transfer work at least one printing unit and possibly also one or more coating units are arranged downstream.
  • the printing units can also be designed as anilox printing units.
  • Within the printing press turning devices can be provided between printing units. These may be upstream or downstream with respect to the film transfer device.
  • inline processes such as embossing, creasing, slitting, punching, inkjet printing or marking or the like may be provided in the printing press.
  • the printing machine can be designed as a so-called offline machine, so that only one commissioned work with anilox inking unit for the adhesive application and a coating unit are provided.
  • All configurations can be equipped with film timing and with a format-wide film web or several narrow film sub-webs.
  • a further color printing to the image-wise coated printing sheet with a metallized layer in a printing unit 50 following the coating unit 2.
  • the printing unit 50 has, as usual in offset printing units, the counter-pressure cylinder 40, an associated rubber or blanket cylinder 41 and a plate cylinder 43 associated therewith.
  • the plate cylinder 43 are here shown schematically an inking unit and a dampening unit assigned.
  • a further pressure gap 60 is formed between the counter-pressure cylinder 40 and the blanket cylinder 41. In this printing gap 60 ink is applied from a spanned on the plate cylinder 43 printing plate 44 via a arranged on the blanket cylinder 41 cover 42 on the sheet.
  • the press nip 60 an approximately line-shaped pressure is exerted on the printed sheet, which also acts on the image parts of the metallic coating. It is provided here that the pressure in the press nip 60 is matched to the pressure provided in the transfer nip 6.
  • a short inking unit is shown in the coating unit 2, which is equipped for transferring ink or paint from a chamber doctor blade 61 via an anilox roller 62 to a cylinder-sized applicator roller 63.
  • the application roller 63 cooperates with the plate cylinder 12.
  • the ink feed is out of action in the coating unit 2 due to the performance of the film transfer.
  • a short inking unit can also be provided in the commissioned work 1 or in the printing or coating unit, which is arranged downstream of the coating unit 2. Then the advantageous effects of short inking technology can be implemented at these functional positions.
  • the film advance of the transfer film from the film supply roll 8 to the transfer nip 6 and the film collection roll 9 is controllable such that the transfer film 5 is stopped as far as possible if no transfer of the image-forming layer is to take place:
  • a contoured pressing surface can be provided as the surface of the pressing cylinder 3.
  • a pressing surface limited to the area to be coated is used on the pressing cylinder 3.
  • a cut-out printing blanket, an imageable plastic printing plate or a pressure pad which is preferably releasably fastened to a smooth base, possibly stickable or magnetically attachable, can be used to support the limited pressing surface.
  • a further improvement of the film utilization of the type described results from the fact that the transfer film 5 is divided into one or more Operafolienbahnen lesser width.
  • the utilization of the transfer film 5 can be improved even in zonally different lengths coating areas within an arc.
  • the image-forming layer for example a metallization layer, can be applied by means of an adhesive which reacts to ultraviolet radiation.
  • so-called UV negative pressure paint can be applied. This UV negative pressure ink is applied by means of the applicator 1 for the adhesive in a corresponding manner via an offset printing plate.
  • a device for UV drying must be arranged.
  • the adhesive effect of the UV negative pressure ink is slightly better than that of a normal adhesive. This results in improved smoothness and thus gloss effect of resting on the sheet imaging layer.
  • a UV dryer 15 is to be provided either after the applicator 1 for predrying the adhesive application.
  • a UV dryer 15 penetrating the imaging layer can be arranged, for example, on the impression cylinder 4 of the coating unit 2.
  • the adhesive effect of the UV negative pressure ink can be fully utilized and the smoothness of the coating is increased.
  • the adhesive media required in the transfer of the imaging or metallized layer can, as described, be of different consistency and require different processing criteria
  • the coating unit 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 machine 2 can also be placed at any other location within the machine. This is intended to make it possible for the desired imaging layers, such as metallization layers, to take place both before, as well as after and between the application of ink layers.
  • the coating module is designed as a transportable unit.
  • the coating module consists of a frame with a Folienrollollung and a Folienaufrollung. To couple with the respective printing unit to be used as a coating unit 2, it has a coupling surface to a defined area of the required printing unit. The corresponding mating surface is usually at the top of the required printing unit.
  • the coupling surface can also be provided laterally or on the end faces of the printing units.
  • the printing unit required for the application of adhesive as an application unit 1 only has to be set up for the application of adhesive (corresponds to a normal application of color) like a printing unit used by default.
  • the facilities required for the film guide devices of the transfer films near the film supply roll or film collection roll are connected to the coating module. Only in the field of protection of the printing units are appropriate inlets and outlets for the supply of the transfer film 5 to or the return of the transfer film 5 provided by the pressing cylinder 3. Here necessary deflections for the transfer films can be easily connected to the security and can be removed if necessary.
  • the supply of the required different transfer foils to the printing sheet can take place successively.
  • the transmission of a first adhesive pattern in a first applicator 1 done and provided in a first coating unit 2 with a first type of metallization Overlaying this, in a following application unit 1 another, the first enclosing or overlapping adhesive pattern can be applied and provided in a second coating unit 2 with a metallization layer of a second type. In this way, for example, intersecting image patterns of a silver-colored layer and a gold-colored layer can be produced in a coating pass.
  • FIG. 2 shows an alternatively configured printing unit 80 with a further design of a short inking unit 79 .
  • This printing unit or inking unit 79 may be assigned to the coating module 2 as a color printing unit or else in the application unit 1.
  • the short inking unit 79 includes an anilox roller 70.
  • the anilox roller 70 are assigned a plate cylinder 71, a blanket cylinder 72 and an impression cylinder 73 in the printing unit 80.
  • a dampening unit 78 is provided for the dampening of the printing plate in the wet offset.
  • the short inking unit 79 has a roller blade 74 on the anilox roller 70.
  • the roller blade 70 is assigned to the anilox roller 70, a doctor blade 81 in conjunction with an ink supply 75.
  • printing ink or adhesive is applied to the anilox roller 70 via the ink supply 75 by means of the doctor blade 75.
  • the roller blade 74 rolls the printing ink or the adhesive into the cup structure of the anilox roller 70.
  • smoothing rollers 76 once more uniformly act on the ink or adhesive layer on the anilox roller 70. In order for the function of the smoothing rollers 76 to be retained, they are assigned a cleaning blade 77 for discharging excess quantities of printing ink or adhesive.
  • This short inking unit 79 shown here due to its compact design and the short transfer paths for the liquids to be processed, is particularly well suited for producing printing ink or adhesive layers of constant quality and apply these continuously to printing forms of any kind. Thus, an extremely good and uniformly executable adhesive dosage is also given for the cold foil transfer.
