Definitions

  • the invention relates to a device in a machine for transferring imaging layers from a carrier film to printing sheet according to the preamble of patent claim 1.
  • EP 0 569 520 B1 describes a printing material and a printing device using this material.
  • a sheet-processing machine which has a feeder and a boom, between two units printing units and a coating unit are arranged.
  • an adhesive pattern is applied by the planographic printing method to carry out a so-called cold foil transfer method.
  • each sheet is given an adhesive pattern. Thereafter, the sheet is passed through the coating unit, wherein by means of the pressure roller of the pressure cylinder resting on the impression cylinder 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. After further transporting the printing 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.
  • the object of the invention is therefore to provide a device by means of which the transfer of an imaging layer on a sheet can be done economically and safely, the device should be easy to handle.
  • At least one inkjet printing device is arranged upstream of the transfer nip in the coating unit.
  • the adjustability for the functionality and operation of the cold foil transfer is adjusted so that the use of the inkjet printing device for the cold foil transfer is tailored to the needs of the subjects to be created in the film transfer.
  • the device can be used in an advantageous manner if an improvement in film utilization is to be achieved by dividing the transfer film into one or more partial film webs of lesser width. In combination with the aforementioned method, it is thus also possible to use different types of film side by side.
  • Figure 1 an overview of a printing press with a

  • the two printing or application plants 1, 2 are used for the following purposes:
  • a printed sheet is provided with an imaging adhesive pattern in the first printing or application unit 1 (designation nowcoattechnik 1). Thereafter, a transfer sheet 5 is passed through a transfer nip 6 in the following printing or application work together with a printing sheet, the transfer sheet 5 is pressed in the transfer nip 6 against the sheet (now designation coating 2).
  • the applicator 1 may be a known offset printing unit with an inking a plate cylinder, a blanket cylinder and a sheet leading impression cylinder 4. Likewise, this may be a so-called paint module in which the blanket cylinder is designed as a forme cylinder. The form cylinder is coated with paint or glue from e.g. supplied as a chamber doctor system trained device instead of the inking unit.
  • the coating unit 2 may also be a known offset printing unit.
  • the transfer nip 6 in the coating unit 2 is formed by a press roll 3 and an impression cylinder 4.
  • the press roller 3 can correspond to the blanket cylinder and the impression cylinder 4 to the impression cylinder of an offset printing unit.
  • the press roller 3 can correspond to the forme cylinder and the impression cylinder 4 to the impression cylinder of a paint module of a sheet-fed press.
  • the transfer films 5 have a multilayer structure. They have a carrier layer on which an imaging layer is applied by means of a release layer.
  • the separating layer serves to facilitate lifting of the imaging layer from the carrier layer.
  • the image-forming layer may be, for example, a metallized layer or a glossy layer or a texture layer or a colored layer or a layer containing one or more image patterns.
  • a film supply roll 8 and a film collection roll 9 are assigned to the coating unit 2. The transfer film 5 is removed from the film supply roll 8 and rolled up on the film collection roll 9.
  • the transfer film 5 is guided during cold-foil transfer from the side facing the applicator 1 side of the coating unit 2 to the transfer nip 6, approximately tangentially discharged to the press roller 3 through the transfer nip 6 and on the opposite side.
  • the transfer process of the imaging e.g. Metallized layer on the printed material takes place in the transfer nip 6 between the press roller 3 and the impression cylinder. 4
  • the press roll 3 is provided with a press cover.
  • the press fabric is held in a cylinder channel on jigs.
  • machine controls are provided for controlling the processes. These machine controls include all setting options for the printing units or application units of the printing or application machine, which are contained in the coating unit 2 and the commissioned work 1. Thus, the setting of the gap dimension of the surfaces of the cylinder 3, 4 to each other with respect to the transfer nip 6 is adjustable.
  • a control device may be provided which ensures the setting of the printing press on the cold foil transfer for corresponding settings in the printing units.
  • the machine control of the printing press therefore provides that a special adjustment is provided for the cold foil transfer mode of operation.
  • the present invention enables the use of high-quality digital printing systems, in particular inkjet in the environment of a sheet-fed press.
  • Digital printing offers a variety of applications and can be used in combination with other processes to produce high-quality printed products.
  • an ink can be used as an adhesive, which opens in conjunction with the known method of cold foil transfer, the possibility of using this high-quality method in conjunction with any desired customization of the printed product.
  • the adhesive is usually transferred via one of the film transfer device before stored offset printing unit.
  • the adhesive may also or additionally optionally also be applied in conjunction with a viscosity adjustment for processing in an inkjet printhead by means of such a digitally controllable printhead.
  • the slide transfer can be used to apply individually configurable information.
  • it may be possible to dispense with the offset printing unit for imagewise application of the adhesive if the adhesive is to be applied exclusively by means of inkjet printheads, or additional information is e.g. a writing or a code in combination with a two-dimensional application of adhesive applied by offset printing plate.
  • the sheet-fed printing machine shown in Figure 1 is as described suitable for cold foil transfer. According to the invention, however, an inkjet printing device 30 is now arranged from one or more inkjet printheads for applying adhesive in the first printing unit or applicator 1 on the printing cylinder 4.

  • a base coating in the inkjet printing device 30 on the feed table 21 can be made. Then a full-surface application of adhesive in the following applicator 1 is present at this coated position, for example, particularly smooth and adhesive.
  • This version is well suited for low quality substrates.
  • the adhesive force of the adhesive can be further enhanced by the combination of several inkjet printing devices 30 on printing cylinders 4 or on a printing cylinder 4 and on the transfer sheet 5 or varied in the area. Therefore, it is also useful if several of the inkjet printing devices 30 are combined with each other in the sheet-fed press for cold foil transfer.
  • the arrangement of a plurality of inkjet printing devices 30 is particularly advantageous since then different Be Anlagenungssujet can be generated in a simple manner and also interchangeable.
  • the applicator 1 can also be designed as an inkjet printing unit, so that only digital adhesive application is possible there
  • inkjet printing devices 30 consist of one or more inkjet printheads, which can be seen in the transport direction parallel to each other, arranged in series or offset from each other.
  • the selection of the printing combinations of various inkjet printing devices 30 with or without interaction with the existing printing units can be done on the basis of precursor data.
  • a quality control can be carried out via an inspection device, which is arranged approximately on the boom 22 or the last printing unit (paint module 10). It is then possible to detect errors in the adhesive application via the inkjet printing devices 30, to wait for them or to position or switch on alternative inkjet printing devices 30 that can take over the adhesive application.
