Definitions

  • the invention relates to a method, a device and a transfer film for transferring imaging or covering layers from a carrier film to printed sheets according to the preamble of patent claims 1, 10 and 18.
  • a printing sheet After a printing sheet is provided with a two-dimensional adhesive application or an adhesive pattern, it is passed through the coating unit, wherein by means of the pressure roller, the pressure sheet lying on the impression cylinder is brought into contact with the film material.
  • the down-facing functional layer engages tightly with the adhesive-provided areas on the signature. Thereafter, the functional layer adheres only in the area provided with adhesive pattern or even full-surface adhesive areas on, wherein the carrier film, the functional layer is removed in the region of the adhesive pattern.
  • the print sheet is laid out in the coated state.
  • a disadvantage of the described procedures is that they are not flexible to use, require extensive know-how on the complex processes and are difficult to handle.
  • the object of the invention is therefore to provide a method according to the preamble of claim 1 and a transfer film according to the preamble of claim 18, by means of which a flexible coating of printed sheets can be simple, secure, economical and accurate, the method and the transfer sheet easy to handle should be.
  • a method is proposed by means of which a detachable partial coating for exposing coverable information media to be coated, e.g. with information properties, carried out in a sheet-fed rotary printing press and the coating is carried out in the cold foil stamping process.
  • coating units such as paint modules, a device for perfecting and coating modules for a one- or two-sided film application are possible.
  • the production of effect and functional application or film composite packaging can also be made possible by methods and apparatus in conjunction with a printability of the printing substrate on both sides.
  • 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 may correspond to the blanket cylinder, the impression cylinder 4 to the impression cylinder of an offset printing unit.
  • the press roller 3 can also correspond to the forme cylinder and the impression cylinder 4 to the impression cylinder of a paint module.
  • a web guide for transfer films is shown within the used for the film transfer coating 2 .
  • an integrated in the applicator 1 film transfer device may be provided, whereby an integrated film application module is created.
  • a press roll 3 ' is assigned downstream of a printing gap between a blanket or forme cylinder 13 and the impression cylinder 4 on a counter-pressure cylinder 4.
  • the cold foil stamping takes place in a single integrated foil application module FA, as indicated in FIG.
  • an applicator can also be arranged in a compact design within the coating module in an integrated film application module FA.
  • the transfer film would be guided here around the blanket cylinder 13 or approximately tangentially past it through the designated printing nip.
  • Such an adhesive applicator device 1 ' may consist of a compact forme cylinder for supporting a printing form for the adhesive and an applicator of a chamber doctor blade and an anilox roller for supplying the adhesive.
  • the adhesive application is first carried out on the printing substrate and the film application is carried out immediately thereafter.
  • the film supply roll 8 is assigned to the coating unit 2 on the sheet feed side.
  • the film supply roll 8 has a rotary drive 7 for the continuous controlled feeding of the transfer film to the coating unit 2.
  • a film feed deflection or tension rollers for guiding the transfer film 5 may be provided in a substantially constant tension against the press roller 3.
  • a film collecting roller 9 is provided for the used sheet material.
  • a rotary drive 7 on the film collecting roller 9 is always advantageous. It can even be provided that the transfer film 5 is conveyed on the outlet side by means of the rotary drive 7 and held taut on the inlet side by means of a brake.
  • the device described it is possible to partially seal or laminate a printing substrate and to provide it with an opaque surface layer.
  • the device for the film transfer in a printing units of a sheet-fed printing machine downstream printing or coating plant is arranged.
  • the surface of the fresh print is further protected.
  • rubbellack layers are suitable, which serve to cover information, so that they can be exposed only when needed.
  • a well-known example of this are lots or informational resources with an educational or learning character.
  • the function of the cover can also be realized by peelable covers in the form of a film strip. This will change the type of application the opaque or opaque coverage of information changed only in its handling.
  • the basis of the application is the variability of the layer to be applied to a printing sheet with regard to its adhesion to the substrate and with respect to its internal structure.
  • an adhesive which transfers the image-forming layers from the carrier film to the substrate or the printed sheet under pressure is generally required.
  • the adhesive also ensures that the contour of the desired coating is adhered to during layer transfer to the finest details. On the other hand, even thicker layers can be well, i. be transferred sharp edges, provided that their internal strength falls below the adhesion to the adhesive.
  • a Rubbellack Mrs is particularly well suited. Their strength is so high within the layer that a layer can be safely detached and transferred. On the other hand, because of its consistency as a peelable layer, it has a comparatively low intrinsic strength and can therefore be easily transferred even in thicker layers.
  • the functions of the solubility of the layer of the carrier film, the edge-precise separation of the covering layer and the sufficient adhesion to the substrate of the printing material can be determined sufficiently accurately beforehand.
  • the central element here is the adhesive which, in the consistency and drying state, causes the edge-to-edge detachment when the layer is transferred from the carrier film to the substrate.
  • a covering or opaque layer of solid foil material may also be provided.
  • the film is deducted in total.
  • the predetermination of the function of the detachable or exposable cover of an information area with simplified handling for the end user in relation to the film application is more difficult to solve.
  • the film must either be very strong colored for safe coverage or it must have a sufficient thickness. If heavily colored, a thinner film may be used, but it must have sufficient strength to allow it to be easily removed from the substrate.
  • the consistency and the drying state of the adhesive can in turn be chosen so that the adhesion of the film order can be executed exactly and thereby also sufficiently easily releasably adjusted.
  • the adhesion to the substrate of the printing material is much easier to solve.
  • the adhesion can be relatively strong because the thicker film is more durable when peeled off from the substrate. Therefore, the consistency of the adhesive can be set a little more variable here. This is also necessary because the edge-to-edge separation on the carrier film is more difficult with thicker film layers and requires stronger adhesion as well.
  • the information to be covered can also be applied during the coating process.
  • printing methods are very different Type applicable.
  • an information to be covered can be applied by means of ink-jet printing and then covered.
  • the information can also be carried out in offset printing, flexographic printing, gravure printing or in other types of non-stop printing processes.
  • a machine configuration can be provided which provides a first film application module in front of the first printing unit transmitting a color or a coating and a second film application module for the last color-transferring printing unit.
  • a first coating or lamination can be applied directly to the substrate and a second partial coating can be applied over the printed image.
  • the combination of coating units such.
  • paint modules a device for perfecting and coating modules for a one- or two-sided film application are possible.
  • inventive method and apparatus the production of functional application or information media of o. G. Art also be possible in conjunction with a two-sided printability of the substrate.
  • FIGS. 2 and 3 For this purpose, machine configurations are schematically illustrated in FIGS. 2 and 3, which allow for example corresponding operating modes.
  • printing units D are provided for processing of viscous printing inks. Instead of the printing units D can also be optionally used paint modules for processing liquid coatings or coating media. Printing units D can also be used to apply a coating of liquid coating media.
  • FIG. 2 shows a first variant of such a configuration.
  • the illustrated printing machine has after two to the sheet feeder AN subsequent printing units D or paint modules or a combination of printing units and paint modules on an applicator 1 and a coating module 2, which also as integrated foil application module FA can be arranged within a printing unit.
  • a turning device W which in a sheet-fed printing machine evert a one-sided printed or coated printing sheet, so that its back side becomes the front side, which can subsequently be printed or coated.
  • the turning device W acts as a transfer device T for transporting the sheet without turning.
  • the Wende- / transfer device W / T Then several more printing units D are provided to the sheet delivery AU if necessary.
  • each printing sheet can first be printed on one side or bicoloured or printed and coated with this printing machine, then coated with a covering film layer over part of the area, then possibly turned and subsequently printed again in multiple colors.
  • An application example of this is packaging or other information media that contain a functional area for information that should not be directly visible.
  • the detachable cover of the information contents described here also prevents the information present on the packaging or the information medium from reaching undesired times or from undesired addressees, or else from being adversely affected.
  • FIG. 3 shows a second configuration.
  • the illustrated printing machine then has a one- or two-part film application module on the sheet feeder AN and subsequently a turning / transfer device W / T, which serves to turn over a printed sheet coated with film material so that its previous underside is subsequently printed or coated can be.
  • This is followed by the turning / transfer device W / T one or more printing units D and then an applicator 1 and a coating module 2, which can also be arranged as an integrated film application module FA within a printing unit.
  • an applicator 1 and a coating module 2 which can also be arranged as an integrated film application module FA within a printing unit.
  • several further printing units D are provided up to the sheet delivery AU.
  • each printed sheet can first be printed one-by-two or two-color from its rear side or coated or laminated. Then the printed sheet can be turned over, then printed in multicolor and subsequently coated with a covering layer over part of the surface and subsequently optionally reprinted or coated.
  • a covering layer over part of the surface and subsequently optionally reprinted or coated.
  • packaging or information media that require a one-sided jewelry or protective layer for media content.
  • a double-coated product can be provided in a simple manner with envelopes, ornamental leaves and covered information areas to supplement image or text content, with a possibly sensitive special coating is added later and so safely applied.
  • the detachable coating of the type described can also be achieved by painting the printed sheet in a varnishing or printing unit D before the film application in the film application module FA. This process creates a smoother surface of the press sheet, which makes the glue work better. At the same time, the solubility of the coating from the surface of the printing sheet is improved.
  • the device includes a coating module for the cold foil stamping process before and / or after a turning device within a sheet-fed printing machine and complements the described process engineering in an advantageous manner.
