Definitions

  • the invention relates to a method and a device for transferring imaging or covering layers from a carrier foil to printed sheets according to the preamble of patent claim 1 and of patent claim 17, respectively.
  • 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 resting 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 applicable, require extensive know-how on the complex processes and are difficult to handle. Above all, the previously known production methods are limited to the processing of substrates made of paper or cardboard. A coating of film substrates in the cold foil stamping process has not been previously known.
  • the object of the invention is therefore to provide a method according to the preamble of claim 1 and a device according to the preamble of claim 17, by means of which a film coating of sheet from films of different quality can be simple, safe, economical and accurate, with method and device easy should be manageable.
  • a method in the application of the film application also substrates from films by their pretreatment is made possible.
  • This allows functional packaging, e.g. provided with jewelry effects, using a sheet-fed rotary printing press and the film coating is carried out in the cold foil stamping process.
  • the film application on film substrates in conjunction with an offset printing machine with upstream or downstream paint modules done.
  • the application is carried out in the printing unit or in a coating module.
  • Before or after the application can be additionally printed and intermediately dried eg with the help of a UV dryer.
  • the method is initially determined by the fact that the film application is performed as a finishing application or functional application on film printing material.
  • the inline process for film application on film substrates expands the range of applications.
  • the pretreatment of the film printing material and the application film can be carried out by a corona treatment.
  • An advantage of the method is that no heat input or only a reduced heat input compared to hot foil lamination takes place. This results in a greatly reduced Passerverzug, which is particularly important for film substrates.
  • the applicator 1 may be a per se known offset printing unit with an inking unit 11, a plate cylinder 12 and a blanket cylinder 13.
  • the blanket cylinder 13 cooperates with a counter-pressure cylinder 4.
  • the coating unit 2 can also be formed by an offset printing unit.
  • 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 press roll 3 may also correspond to the forme cylinder of a paint module.
  • a web guide 14 for transfer films is shown within the coating unit 2 used for the film transfer.
  • the transfer film 5 is thereby switched on and executed by protective devices 15 of the coating unit 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 press roll 3 (as a blanket cylinder or forme cylinder or separate press roll) carries on its surface a compressible or damping, e.g. also provided with a compressible intermediate layer element.
  • the press roll 3 can be provided with a press fabric 10, for example as a plastic cover, comparable to a blanket or blanket, which is held in a cylinder channel on clamping devices.
  • the film feed of the transfer film 5 from the film supply roll 8 to Transfer gap 6 and the film collection roll 9 is stepwise controllable, the transfer sheet 5 is then stopped, if no transfer of imaging or covering layers should take place.
  • the associated device preferably includes a corresponding feed control for the transfer sheet 5, which ensures that at least the lying in the region of the press roller 3 and the impression cylinder 4 part of the film web is stationary as long as the cylinder channel passes.
  • a further improvement of the film utilization of the type described results when 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 zonally different lengths coating areas within an arc.
  • dryer 16 can be provided in the film application module thus formed from the applicator 1 and the coating unit 2, by means of which the adhesive application or the entire film coating can be dried.
  • the adhesive application or the entire film coating can be dried.
  • UV dryer for example UV dryer in question.
  • the film application module may include a monitoring device 17 for scanning the sheet surface.
  • the monitoring device 17 enables the evaluation of image contents of the coating and the detection of defects in the film coating.
  • Such a monitoring device can also be provided in conjunction with the printing press, in which the film application module is integrated. Then it can be arranged for example in the sheet delivery of the printing press or a last printing unit.
  • the device for the film transfer in one of the printing units of a Sheet-fed printing machine arranged downstream printing or coating unit.
  • the surface of the fresh print is finished or protected by means of the film coating.
  • a second such device within the sheet-fed rotary printing press of the first device for the film transfer, can be arranged downstream, so that a double film coating of a sheet is possible.
  • a configuration can be provided which provides a first film application module in front of the first color or coating transfer printing unit and a second film application module after the last color transferring printing unit.
  • a first film coating can be applied directly to the substrate and a second film coating can be applied over the printed image.
  • methods can also be carried out, in the use of which a simple film coating or else multiple film coating of functional or single-sided packaging, e.g. with jewelry features, becomes possible within a sheet-fed rotary printing press.
  • 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 of film composite packaging can also be made possible in connection with a printability of the printing material on both sides.
  • the method is characterized in that the film application is carried out as a finishing application or functional application on film printing material.
  • the pretreatment of the Folienbedruckstoffes and the application film carried out by a corona treatment.
  • the use of heat-reduced UV dryer systems in conjunction with the film application in cold foil lamination is used.
  • the film guide can be made tangentially through the transfer gap or loop around the blanket cylinder.
  • the film application is now to be carried out on film substrates in conjunction with an offset printing press with upstream or downstream coating modules.
  • the application is carried out in a printing unit or in a coating module.
  • the film application may additionally be printed and intermediately dried e.g. with the help of a UV dryer.
  • UV printing inks In the process of printing on film substrates, so-called UV printing inks are often used. UV printing inks can be cured very quickly and efficiently with the aid of UV dryers, so that a color layer firmly adhering to the film substrate is produced. Furthermore, in the case of film printing materials, a so-called corona or plasma treatment is often carried out to improve the color adhesion. By acting on the film surface with a corona discharge or a plasma, its surface tension can be changed so that the printing inks to be applied are securely adhered. In this way, an optimized appearance of the print is achieved.
  • UV printing inks For the drying of UV printing inks, special dryers have been developed which operate at comparatively low temperatures.
  • Known systems for this purpose are conventional UV lamps or UV cold radiators, e.g. as excimer radiator. But there are also so-called NIR dryers in question.
  • An advantage of the proposed method is that the heat input through the dryer irradiation is greatly reduced or greatly reduced compared to that in the hot foil lamination. This results in a greatly reduced thermal influence on the film substrate, so that sets a strong improvement on the printed product with respect to the resulting from the embossing process Passerverzuges.
  • the inline process for film application on film substrates expands the application spectrum of a correspondingly equipped printing press in a special way.
  • FIG. 2 shows a first variant of such a configuration.
  • the illustrated printing press has a roll-bow feeder RB.
  • foil sheets are cut from a roll of film accurately and fed in the machine cycle of the press.
  • a printing unit D or a paint module is arranged.
  • the printing unit D or the paint module is followed by an application unit 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.
  • intermediate dryer Z are arranged, by means of which the applied in respective workstations coatings can be dried.
  • a discharge device E In the area of feeding the film sheets from the roll-bow feeder RB into the first workstation of the printing press, a discharge device E is provided. It serves to improve in a conventional manner, for example by means of a corona discharge, the surface properties of the film sheet for the adoption of coatings.
  • the discharge device E can also be integrated into the roll-bow feeder RB, so that the surface treatment of the foil sheet is also effective for the sheet transport to the printing press.
  • a sheet of film cut from a film roll can first be coated, then coated with an imagewise or flat film layer and subsequently printed again in multiple colors.
  • One application example for this are films for packaging or decorative sheets, which require additional finishing in addition to printing.
  • FIG. 3 shows a second variant of such a configuration.
  • the illustrated printing machine has a sheet feeder AN, to which a discharge device E for film treatment is assigned. Subsequently, either a printing unit D or a paint module is provided. This is followed by one or two-part film application module FA. Subsequently, a printing unit is again arranged, which is followed by a so-called turning device W.
  • the turning device W serves to evert a foil sheet provided on one side with a film coating, so that its previous underside can subsequently be printed or coated from above.
  • the applicator 1 and a coating module 2 adjoin the turning device W, which can also be arranged as an integrated film application module FA within a printing unit. Thereafter, if necessary, several further printing units D are provided up to the sheet delivery AU. Before feeding the film sheets to the film application module FA, they can be exposed again, but now with their upper rear side exposed to the action of a discharge device E.
  • each foil sheet can first be coated from its top, then provided with a film coating, then printed or coated, then turned, then provided with a further film coating and subsequently printed again in multiple colors.
