Definitions

  • the invention relates to a finishing process and an associated coating unit for a printed product, wherein the coating unit is part of a printing press, according to claims 1 and 17.
  • the paint or ink application of radiation-curing paints or printing inks on a printing or flexographic printing on a substrate is one of the standard processes in the printing industry.
  • Flexo or coating units are described as coating units, inter alia, in EP 0620115 B1.
  • the paint or paint application is carried out by a Einbewbetechnik, e.g. a chambered doctor blade and anilox roll, onto a printing form, e.g. a flexo, a high pressure or a trimmed or full-surface rubber or plastic cloth may be, and is transferred from this printing form as a liquid on the substrate.
  • a Einbewbetechnik e.g. a chambered doctor blade and anilox roll
  • a printing form e.g. a flexo, a high pressure or a trimmed or full-surface rubber or plastic cloth may be, and is transferred from this printing form as a liquid on the substrate.
  • the highest possible color or paint film is to be achieved on the substrate, for example, to achieve a barrier, eg against moisture, water vapor or grease.
  • a barrier eg against moisture, water vapor or grease.
  • very high amounts of paint or lacquer must be offered by the Einbewbetechnik, since at each cleavage site, the paint or color film splits in about half. This splitting also takes place in the printing gap between the printing form cylinder and the printing substrate, so that a part of the paint or color film remains on the printing form cylinder after the split.
  • the transferable paint or ink quantity of the inking unit is limited and high amounts of paint can lead to spraying and run-in of image elements on the printing plate.
  • Another aspect speaks against the transfer of a liquid paint or color film on the substrate.
  • a liquid paint or color film on the substrate.
  • matt or glossy effects are desired on a sheet, which can be produced only with elaborate double-layer works.
  • a glossy, in the other coating unit is applied a matt lacquer.
  • embossing in the paint you could create a matte effect by a rough or textured embossing surface, but also requires two coating units, the embossing must be in the form of an intermediate dryer cured paint. It is very time-consuming to produce two works, especially in the case of embossing or coating forms, since the processing of the high-pressure plates is very time-consuming to coordinate.
  • the object of the invention is to provide a finishing process and an associated coating unit for a printed product.
  • the method is characterized in that a paint or color film is radiation cured and the cured paint or color film is then transferred as a closed film, preferably 100%, to the printed product and there adhering under pressure or with the aid of a bonding agent.
  • the finishing process allows only a decorative design of a printed product, but can also fulfill tasks in the context of trademark protection by hard-to-imitate surfaces by a surface design.
  • FIG 1 schematically illustrated process steps of the inventive method
  • FIG. 2 shows a device according to the invention for carrying out the
  • the principle of the finishing process according to the invention is based on the fact that a thermally or radiation curable lacquer 2 is applied to a smooth or structured plate 1 with an application device 3, then the lacquer 2 is dried in the next step by a heat source or a radiation source 5, 14 . Is hardened and the cured paint film 2 is transferred to the substrate 4 in the printing nip 9 completely or at least for the most part as a film and remains there.
  • the paint layer surface 4 lying on top of the plate is located after transfer to the printing substrate 6 on the side of the paint film 4 facing the substrate, i. the outer surface of the paint film is determined by the structure of the plate.
  • the adhesion of the cured or dried coating film 2 on the printing substrate can be effected by pressing in the press nip 9, optionally with exploitation. Tung thermoplastic effects or by applying a primer on the substrate, for example via an offset printing unit D or coating unit L in advance. The primer could also be applied to the substrate by spraying with an adhesive nozzle or roller applicator.
  • the adhesion promoter in the direction of rotation of the forme cylinder 13 after the drying or curing unit 14 can be applied to the dried or hardened paint film by spraying with an adhesive application nozzle or a roller application device.
  • the paint surface on top of the substrate is determined in its nature substantially by the surface of the plate 1.
  • the nature of the plate therefore offers a variety of design options for producing a variety of effects that can be combined with each other in any way.
  • the plate 1 may have wholly or partially an extremely smooth polished surface in order to achieve a high gloss.
  • the plate 1 can also have textures which produce a matt or textured effect.
  • such a plate 1 can even be used to produce lens effects, e.g. create a 3D impression through the lens effect.
  • the design possibilities are very diverse, whereby not only visual and haptic effects can be generated, but also a significant contribution to product protection in the sense of brand protection is contributed, since such a complex structure of a paint surface without the possession of the corresponding plate, difficult to replicate.
  • a possible structure on the plate can be even, but also pictorial. As a result, for example, a kind of watermark can be integrated into the paint film.
  • An essential requirement of the plate surface 1 is that the paint film can be completely detached from it and the adhesion to the printing material 6 is higher than that of the plate 1. This can be achieved by a variety of surfaces with release properties or by a high smoothness the surface. A surface with release properties would be a silicone coating. But there are a variety of surfaces and materials that meet this condition.
  • the surface of the plate 1 could e.g. in the case of a polished or chromium-plated metal surface, these have properties which are even optimized for radiation curing and which reflect UV rays that pass unused through the paint film back into them. This can increase the curing efficiency.
  • a separating liquid could be, for example, water, silicone oils and water / silicone mixtures, as used in web offset printing. In principle, any liquid which fulfills the desired properties can be used as the separating liquid.
  • the paint application of the paint film 2 on the plate can be applied to the plate with a Walzenadoss- 3, a chamber doctor blade with Aniloxwalze or spray nozzles 12. After application, the paint film could optionally be smoothed with a doctor blade or a roller before curing.
  • the drying device which is directed against the plate 1, which is located on the forme cylinder 13, can be infrared radiators alone or in combination with convection drying using a thermosetting lacquer, or UV emitters when using a UV lacquer or electron beam dryer when using a suitable radiation-curing paint.
  • the drying plant can also be a combination of UV emitter and IR emitter when using dual-cure paints that cure radically and thermally.
  • an inert gas such as nitrogen

Abstract

L'invention concerne un procédé de finition et de protection à l'aide d'un vernis durcissant au rayonnement ou séchant thermiquement de la surface de produits imprimés dans une machine d'impression. Pour simplifier l'opération, le vernis placé sur une plaque (1) est appliqué sur un cylindre de façonnage (13) et est ensuite séché ou durci par un dispositif de séchage et/ou de durcissement (5). Dans l'interstice de compression d'un mécanisme d'impression (D) ou de vernissage, le film de vernis (2) ainsi obtenu est transféré en entier de la plaque (1) au produit imprimé sous la forme d'un film. Le procédé est conçu pour être appliqué dans des machines d'impression offset de feuilles.
