Definitions

  • the invention relates to an embossing process which is carried out inline during the printing pass through the printing machine and associated printing products.
  • All known film printing methods have in common that on a printing substrate, such as paper, cardboard or film as sheet or roll, a film is partially applied under pressure and permanently fixed.
  • a printing substrate such as paper, cardboard or film as sheet or roll
  • foils with gold or silver gloss are used as printing foils, but printing foils in various colors with high-gloss or silk-gloss surfaces are also known.
  • the application of the printing film on the substrate is usually done with the technique of stamping foil printing or hot foil stamping. This printing technique resembles in its basic form a high-pressure process and is similar in that respect the book printing.
  • the key common feature is that the printing parts of the printing form are higher than the surrounding non-printing parts. During the printing process, the printing plate is heated indirectly and kept at a constant temperature.
  • the printing medium passing from the printing film to the substrate during the printing process consists of a transfer layer in the form of a thin, multi-layered dry film, which is detachably fastened on a mostly transparent carrier film by means of a separating layer.
  • the transfer layer in turn, has a two-layer structure with silver-colored aluminum vaporization and a mostly colored lacquer layer. This double transfer layer is finally finished with a synthetic resin
  • the transfer film is guided through the printing unit together with the substrate to be printed, wherein the transfer layer is detached from the carrier film and transferred to the substrate by the contact pressure of the heated printing plate at the locations determined by the raised elements of the printing form.
  • the heat transferred from the printing form vaporizes the separating layer between the carrier film and the transfer layer so that the latter easily separates from the carrier film.
  • the synthetic resin layer is activated under the action of heat from the dry to a sticky state, so that the synthetic resin layer forms an adhesive layer between the substrate and the transfer layer.
  • the transfer layer for example in the form of a gold-shining layer, adheres permanently to the substrate at the points predetermined by the printing form.
  • a disadvantage of this known film printing method is that the production and installation of the printing form, i. cliché, requires a very long preparation and set up time. Since the preparation and set-up time accounts for almost half of the total production time, the known film printing process is overall very time-consuming and thus associated with high production costs.
  • a disadvantage of this embossing method is that the embossing process is usually not done during the printing run by the printing press.
  • the embossing is usually done in the post-processing by the sheet is fed to a post-processing machine with a hot foil stamping device.
  • a further disadvantage of this known method is that the use can no longer be expediently printed after the transfer of the film in the hot-foil stamping device, since the film has a high-low structure through the stamping process. Also, after the embossing process, the printed sheet would again have to be fed to a printing machine for color printing, resulting in longer production times and also higher production costs.
  • EP 0 578 706 B1 describes a transfer method, the so-called cold foil transfer method, in which the printed sheet is provided with a layer of adhesive via a printing unit at the points at which the transfer layer is to adhere later. After the adhesive has been applied, the film is transferred in a further process step by contacting the film with the transfer layer thereon in a further printing unit with the printing sheet under pressure, and the adhesive on the printing material removes the transfer layer from the film ,
  • This transfer method is very economical because it can be done inline in a printing machine without limiting the production speed. Also eliminates the costly production of the stamping die, as required for carrying out the hot foil stamping process. The printability of such a film is given inline during the print run by the printing press, so that a variety of color effects can be achieved in an economically meaningful way.
  • a disadvantage of this method is that many users miss the haptic effect of hot foil stamping, since the transferred transfer layer rests substantially flat on the substrate.
  • WO 2005/049322 describes the method combination of the cold foil transfer process with an inline embossing, wherein the embossing step is carried out in a foil transfer upstream or downstream process step takes place during the printing run by the printing press.
  • the possibility of carrying out the cold foil transfer together with the embossing process in a printing unit is not mentioned in this patent publication. Disadvantage of this solution is that at least one coating module and a stamping machine are used, making the machine longer and more expensive.
  • the object of the invention is to combine the cold foil transfer method known from EP 0 578 706 B1 with an inline embossing device in such a way within a sheet-fed press that the advantages of cold foil transfer, namely the economical transfer technique and the subsequent overprintability with the haptic appearance of the hot foil stamping is connected. This is achieved by the devices and methods according to claim 1. Further developments will become apparent from the respective dependent claims.
  • the embossing takes place simultaneously with the transfer of the film layer in the coating module for carrying out the cold-film transfer process.
  • the press roll for example the rubber blanket cylinder of the coating module for carrying out the cold foil transfer process
  • a stamping plate (patrix) whose elevations cover at least the area proportions which are required for the transfer of the transfer layer in the Coating module are provided.
  • the raised area fraction may include the area defined by the adhesive layer preceding the coating module.
  • the sublime land area However, it can also be arbitrarily larger than the area defined by the adhesive application.
  • the counter-pressure cylinder can also be covered with an embossing plate with elevations (male), the elevations corresponding to at least the region on the printed sheet which has been defined in advance by the adhesive application for carrying out the cold-film transfer process.
  • the respective countershape may be an elastic pad or a die with recesses (die). '

Abstract

L'objet de l'invention consiste à combiner le procédé connu de transfert de films à froid avec un dispositif de gaufrage en ligne dans une machine d'impression de feuilles de manière à associer les avantages du transfert de films à froid, à savoir la technique économique de transfert et la possibilité d'imprimer ensuite avec l'aspect visuel de l'impression gaufrée de films à chaud. Cet objet est réalisé en ce que les couches de transfert transférées pendant l'opération de transfert de films à froid sont gaufrées pendant qu'elles traversent la machine d'impression.
