Definitions

  • the invention relates to a method and a device for transferring optically effective parts of a film layer to a printing material.
  • a method of the type required in the preamble of claim 1 is known as embossing foil printing (cf. "Embossing foil printing", published by the Embossing Foil Printing Working Group, Kunststoff, 2nd edition, 1976).
  • the embossing foil printing is comparable to the letterpress and is like this a high pressure process. All parts of the mold, the image of which is to be transferred to the printing material, are higher than the parts of the mold which are not to be transferred.
  • the form is indirectly electrically heated during stamping foil printing.
  • the task of the printing medium to be transferred (comparable to the rolled-up printing ink in letterpress printing) fulfills a very thin, absolutely dry layer on a ribbon-shaped carrier, the stamping foil.
  • the embossing film used in this known method contains the following layers one above the other (seen from the side of the printing material): An adhesive layer (the adhesive force of which is activated by heat during the printing process and which ensures that the following layers are firmly anchored on the printing material), one Aluminum layer (which gives the embossed foil print the characteristic metallic mirror finish), a color-determining layer, a separating layer (which dissolves during the printing process due to the action of heat) and finally a support (which gives the applied layers the necessary strength).
  • An adhesive layer the adhesive force of which is activated by heat during the printing process and which ensures that the following layers are firmly anchored on the printing material
  • one Aluminum layer which gives the embossed foil print the characteristic metallic mirror finish
  • a color-determining layer which gives the embossed foil print the characteristic metallic mirror finish
  • a separating layer which dissolves during the printing process due to the action of heat
  • a support which gives the applied layers the necessary strength
  • stamping foil printing process lies in the need to use a relatively complex metallic high-pressure mold. Problems also arise when optimizing the register if the printing material also has to be printed using other printing processes (apart from the stamping foil printing). For some applications, it is also unfavorable that, in the case of stamping foil printing, the transferred layer elements are pressed into the top of the printing material to a certain extent, which leads to shading of the print on the back.
  • the invention is therefore based on the object, a method of the presupposed in the preamble of claim 1.
  • a rt form so that a the Embossing foil printing is optically and technically at least equivalent printed product with a significantly reduced technical effort.
  • an adhesive is applied to the printing material in a surface shape corresponding to the desired printing result in a printing method.
  • the side of the film layer containing the optically active parts is then brought into contact with the side of the printing material containing the adhesive application, whereby under the action of pressure and heat in the area of the surface shape determined by the adhesive application, optically active parts from the film layer onto the Substrate to be transferred.
  • the area shape corresponding to the desired printing result is not determined by raised parts of a high-pressure mold. Rather, according to the invention, the printing process is divided into two process steps that are separate in terms of time and machine: First, in the first process step creates a quasi-latent image on the substrate by applying the adhesive. In the second process step, this latent image is then made visible in the desired surface optics.
  • Most printing processes such as high pressure, planographic printing, printing, etc., are suitable for carrying out the first process step, since the consistency of the adhesive can be adapted to the printing ink required for the respective process. If the invention is applied to substrates that have already been printed in one or more colors using a different printing process (or are subsequently printed), the adhesive is applied to optimize the register using the same process and on the same printing press as the previous or subsequent color printing .
  • the printing material for the second process step i.e. prepared for the coating.
  • the film layer is pressed against the printing material by means of a smooth contact surface, preferably a full-surface flat or cylindrical jacket-shaped plate.
  • a smooth contact surface preferably a full-surface flat or cylindrical jacket-shaped plate.
  • Machines can be used on the principle of flat on flat, flat on round or round on round.
  • the method according to the invention allows the use of the most varied types of foils, in particular foils with layers of vapor-deposited gold or aluminum with additional lacquering or foils with layers of color pigments or colored or transparent lacquers.
  • This optically effective layer i.e. the color and / or the metal gloss determining layer
  • the carrier layer of the film which changes its state when heated and allows parts of the optically active layer to transfer to the printing material provided with the adhesive.
  • a separate hot-melt adhesive coating can be provided on the optically active layer (but not (unlike in the case of the stamping foil printing process)).
  • the film which is generally in the form of a tape
  • the layer to be transferred by means of a film preferred device.
  • the contact surface for example one with or, without a silicone rubber coating, a completely flat or cylindrical jacket-shaped plate made of metal is heated by a heating device and pressed against the carrier side of the film in the work cycle of the machine. As a result, the layer side of the film is pressed against the printing material.
  • optically effective parts of a film layer are thus transferred to the printing substrate in precisely those elements (ie in a surface shape corresponding to the desired printing result), which are predetermined by the adhesive application of the first process step (ie by the quasi-latent image).
  • the second process step can take place immediately after the adhesive has dried. Instead, the sheets of printing material can also be temporarily stored, transported or even divided before the second process step takes place.
  • further advantages of the method according to the invention come into play: since the film coating takes place in the second process step with smooth, pressure-exerting plates or cylinders, the time-consuming and cost-intensive production of special printing tools with image memories is eliminated. Since the film coating also requires a relatively low contact pressure and relatively little thermal energy, large-format, high-speed special machines or - above all in smaller formats - any existing stamping film printing machines can be used. In any case, the second process step is free from registration problems because of the Passer can be ensured in a simple and controllable manner in the first process step.
  • the separate adhesive application in the first process step makes it possible to adapt the consistency and the layer thickness of the adhesive to the respective requirements of the printing material and to keep the values once found through recipes in the adhesive preparation and by densitometric control when applying the adhesive. It is therefore no longer necessary to produce and keep many different types of color foils with a certain surface appearance; Rather, only a few types (possibly one type) are sufficient for all occurring substrates and surface conditions.
  • the adhesive composition is expediently applied by a visual or measurement technician before it is applied to the printing material Control suitable dye stained.
  • the fresh adhesive application can also be provided with a further coating between the first and second process step, for example with a melt powder coating melted under the action of heat. In this way, relief effects can be achieved without using a printing form with raised moldings, while the back of the printing material remains flat.
  • the second method step can be carried out in larger formats than has been possible hitherto in stamping foil printing because of the thermal expansion of the stamping tools, their weight and costs, and because of the high contact pressure required there.
  • the machines for carrying out the method according to the invention can be of a lighter design because of the low contact pressure required and can be designed for larger sheet formats than comparable stamping foil printing machines. Insofar as the format of existing stamping foil printing machines is sufficient, they can also be used for the new process (although a smooth contact surface is provided instead of a high-pressure mold).
  • the method according to the invention has all the advantages of stamping foil printing: when using foils with metallic transfer layers, all conceivable optical effects can be achieved: for example, metallic high gloss, silk gloss in precious metal and non-ferrous metal colors, bronzing effects with metal pigment layers, etc. permitted when using foils with non-metallic transfer layers the invention the transfer of relatively thick, well-covering layers of paint.
  • the drawing shows the second method step of the method according to the invention in a schematic illustration.
  • an adhesive 2 is first applied to a printing material 1 in a surface shape (image or text information) corresponding to the desired printing result.
  • a film 3 is then brought into contact with the side of the printing material 1 containing the adhesive application 2 in a second process step by means of a heated pressure cylinder 4.
  • the film 3 consists of a carrier layer 5 on which a separating layer 7 and one or more color-determining layers 6 are arranged.
  • the layer 6 can consist of a single pigment paint or lacquer layer or of a vapor-deposited metal layer which is coated on the viewing side with a color-tinted transparent lacquer layer in order to achieve natural metal color or colored metal gloss effects.
  • parts 6a of the optically active layer (s) 6 separate from the separating layer 7 under the action of pressure and heat at the locations determined by the adhesive application 2 and pass to the printing material 1.
  • the image initially latently contained on the printing material 1 by the adhesive application 2 is thus visible through the parts 6a of the optically active layer (s) 6.
  • the film 3 is transported through a film preferred device, not shown. In the area of the pressure zone, the film 3 and the circumference of the pressure cylinder 4 move at the same speed.
