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.
- 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, 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.
- the printed sheet is passed through the coating module, wherein by means of the pressure roller, the printed sheet resting on the impression cylinder is brought into contact with the film material.
- 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. The used in this way transfer film is wound up again.
- the print sheet is laid out in the coated state.
- 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
- the adhesive pattern for transferring the imaging layer from the transfer film is produced with a colored adhesive.
- the image-forming layer on the transfer film can be transparent, semi-transparent, opaque or opaque.
- the device can also be advantageously used in order to improve the use of the film by dividing the transfer film into one or more partial film webs of lesser width.
- adhesive patterns with different colors would then be usable.
- Suitable application devices are well known. The achievable effects extend over the compensation of minute defects, the enhancement of color effects, the combination or superposition of color effects of the adhesive and the imaging layer or the support of the gloss effect of the imaging coating.
- the image-forming layer can be applied by means of so-called UV negative-pressure ink.
- the UV negative pressure ink is applied by means of the printing unit for the adhesive in a corresponding manner via an offset printing plate.
- the application of different imaging coatings or metallization layers within a subject can take place one after the other.
- Figure 1 is a basic illustration of a printing machine with a film transfer device
- Figure 2 shows the structure of a coating module with a film transfer device
- Figure 3 shows a press roller of a coating module and Figure 4 shows a variant for the construction of a commissioned work.
- FIG. 1 shows a sheet-processing machine, here a printing press, which consists of at least two printing units.
- the two printing units are used for the following purposes:
- a sheet to be coated is provided in a first step with an adhesive imaging pattern.
- the application of the adhesive takes place in a device configured as applicator 1, e.g. a conventional printing unit of an offset printing press via existing dyeing and dampening units 11, a printing plate on a plate cylinder 12, a blanket or blanket cylinder 13 and a counter-pressure cylinder 4.
- applicator 1 e.g. a conventional printing unit of an offset printing press via existing dyeing and dampening units 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 lacquering plants can be used here.
- a variant of such an embodiment is shown in Fig. 4.
- 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 sheet 5 is passed through a transfer nip 6, wherein the transfer sheet 5 is pressed in the transfer nip 6 against the sheet.
- a coating module 2 is used which can correspond to a printing unit or a lacquer module or a base unit or another type of processing station of a sheet-fed offset printing press.
- the transfer nip 6 in the coating module 2 is formed by a press roll 3 and an impression cylinder 4.
- the press roller 3 can correspond to a blanket cylinder and the impression cylinder 4 to an impression cylinder of a known offset printing unit.
- the press roll 3 can be a forme cylinder and the counterpressure cylinder.
- Linder 4 correspond to a counter-pressure cylinder of a paint module of a sheet-fed press.
- the coating module 2 downstream of a so-called calendering be provided when the coated sheet to increase the adhesion of the coating or to increase the smoothness and gloss of the sheet is to be rolled under increased pressure.
- transfer sheets 5 are constructed in multiple layers. 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 imaging layer may be e.g. a metallized layer or a glossy layer or a texture layer or a colored layer or a layer containing one or more image patterns.
- the film supply roll 8 is assigned to the coating module 2 on the side of the sheet feed.
- 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.
- film feed and removal guide devices 14 such as deflection or tensioning rollers, pneumatically actuated conducting means, baffles o. ⁇ . Provided.
- the guide devices 14 may also contain aids for introducing the transfer film 5. In this case, automatic retraction aids for the film web of the transfer film 5 can be used.
- the transfer film 5 can be guided around the press roll 3, wherein the transfer film 5 can advantageously be fed and discharged from the press nip 6 only from one side of the coating module 2 (see dashed representation). 1 and depending on the space conditions on the one side of the coating module 2, the film web can be guided in an advantageous manner in the feeding strand and in the discharging strand closely parallel to one another.
- the transfer film 5 can also be fed in and out substantially tangentially on the press roll 3 or wrap it around the press nip 6 only at a small circumferential angle.
- 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. On the film collecting roll 9, the used film material is wound up again. Again, a rotary drive 7 is provided for the optimized production, which is controllable. In essence, the transfer film 5 could also be moved by the rotary drive 7 on the outlet side and kept taut on the inlet side by means of a brake.
- Wear layer of the transfer film 5 on the sheet in the transfer nip 6 between the press roll 3 and the impression cylinder 4 is essential that the surface of the press roll 3 so the blanket cylinder or forme cylinder is equipped by means of a compressible, damping element.
- the press roll 3 is therefore provided with a press fabric 10 or as a roll with a corresponding coating.
- the press fabric 10 or press coating can be performed, for example, as a plastic coating, comparable to a blanket or blanket.
- the surface of the Pressbespan- 10 or press coating is preferably very smooth. It can also be formed from antiadhesive substances or structures. Here, for example, a relatively hard structure in the form of very fine spherical caps comes into question.
- a Press fabric 10 is held on the press roll 3 in a cylinder channel on jigs.
- the press fabric 10 may be equipped to improve the transmission properties in the transfer nip 6 with a targeted elasticity. If necessary, this can act in a compressible intermediate layer. This compressibility is preferably similar or less than in conventional blankets or blankets, which can also be used at this point. The mentioned compressibility can be produced by means of a conventional compressible printing blanket. Furthermore, combined fabrics made of a hard blanket and a soft pad can be used.
- a limited pressing surface can be provided directly on the press roll 3 or on the press fabric 10. This can be worked out of the surface of the press fabric 10 or it can be additionally attached as a partial surface of the material of the press fabric 10 on the press roller 3.
- the film advance of the transfer film 5 from the film supply roll 8 to the transfer nip 6 and the film collection roll 9 is controllable so that as far as possible the transfer film 5 is stopped when no transfer of the imaging layer should take place :
- a control of the transfer film 5 can be made such that the film feed is stopped when passing through a gripper of the sheet-guiding counter-pressure cylinder 4 receiving cylinder channel.
- the grippers hold the printed sheet on the impression cylinder 4.
- the press roll 3 has a corresponding cylinder channel 19 (see Fig. 3), in which a press fabric 10 is supported. In the region of the corresponding cylinder channels, there is no pressing of the transfer film 5 between the press roll 3 (blanket cylinder) and the impression cylinder 4.
- the press roll 3 then continues to slide on the transfer film 5 while the transfer film 5 is stretched freely between the press roll 3 and impression cylinder 4 is.
- 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 zonal different Lie long coating areas within an arc.
- each partial film web is conveyed only exactly in the area where the imaging surface layer is to be applied. In the areas not to be coated, each partial film web can be stopped independently of the other partial film webs, whereby no unnecessary film consumption arises.
- 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 mounted on a sheet-guiding surface of the coating module 2 after the transfer nip 6 and optionally sealed off from the track ner 16 or be directed to a sheet-guiding surface of the coating module 2 downstream further sheet leading module.
- the pre-applied coated printing sheet can thus be checked for completeness and quality of the coating. As poorly recognized printed sheets can be marked or rejected in a sorter as waste.
- the coating module can be provided with means for conditioning the transfer film in order to improve the layer transfer and the coating result.
- the film web 5 can be influenced by means of the film guiding device 14.
- the adhesive layer taking over the application of the imaging layer receives a corresponding coloring.
- the adhesive layer may be colored in silver-colored or glossy films in a gray tone.
- the adhesive layer may be colored in a yellow tint.
- the imaging layer may be so complete or semitransparent, opaque or opaque.
- the optical effect of the imaging coating can also be subsequently influenced.
- the range of application of standardized transfer foils 5 in the production of high-quality coatings with the cold foil stamping method can advantageously be expanded.
- UV negative-pressure ink 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. This results in improved smoothness and thus gloss effect of resting on the sheet imaging layer.
- the adhesive effect of the UV negative pressure ink can be fully utilized and the smoothness of the coating is increased.
