Definitions

  • the invention relates to a method for producing a rubbelbaren label with hidden information.
  • the scratch-off layer is formed in such a way that it is suitable for the subsequent introduction of the hidden information in the form of a laser inscription and / or a thermal inscription and / or a pressurizing inscription and this subsequently incorporated information such that with the human eye and mechanical aids the hidden information can not be read out.
  • the invention relates to a rubbelbares label in which the hidden information is introduced only after the application of the scratch-off layer.
  • the introduction of the hidden information and a visible information can be done in one step.
  • the scratch-off layer is embodied as an opaque layer in the visible wavelength range, which, however, is transparent for 1064 nm and thus transparent to an Nd: YAG laser beam.
  • a substrate or an upper or lower coating is chosen such that an irreversible information can be introduced by means of a laser beam.
  • a thermal introduction of the hidden information is provided.
  • the scratch-off layer must also have an opaque character for the human eye and for a machine read-out test, but must have suitable behavior for a thermal printing unit, for example, so that one located under the scratch-off layer irreversibly writable thermally activated layer can receive the hidden information.
  • a mechanical printing unit is used for introducing the hidden information.
  • the scratch-off layer must be suitably selected and an underlying layer must be selected so pressure-sensitive that irreversible information arises.
  • a scratch card is described in the form of billets of raw paper, thin board or plastic, which is printed with one caption and / or decor one or more colors while leaving the profit display panel, wherein in the display fields by subsequent action characters, numbers and / or symbols for indicating gain or loss can be brought into appearance and this with a scrubbing layer is invisibly covered to the point of sale and characterized in that the covering layer is a paper provided with a separate thermal transfer recording method on a printed or carrying sign or a film-like coating of an abradable material which can be applied to this covering layer.
  • blank forms are prepared which are provided with a digital printing process, in a preferred embodiment, based on a thermal printing process with the necessary profit / loss indication and then directly in the thermal transfer process with a film-like coating of, for example, opaque pigmented wax or polymer be provided with a suitable melting point.
  • Biller Manfred (Buchdruckaus Lorenz Winter GmbH & Co, "Process for the endless printing of silvery scratch-color fields", filing date: 30.04.1986) is called a process for the endless printing of silvery scratch-color fields.
  • aluminum powder and latex are mixed to a paste-like mass and added a waxy release agent.
  • the composition provided with the release agent is printed by flexographic printing and then treated dry.
  • printed information is provided on a support and at least a part of the printed information is covered with a scratch-off layer.
  • an overprint layer is provided over the scratch off layer having an image obtained from a drawing in which the colors used in the drawing have been separated into screened halftone images of each color and which are used to provide the overprint layer.
  • the images are superimposed to form the overprint layer in individual printing steps.
  • a typical application is the communication code for a rechargeable telephone card or a credit card.
  • the secret information is introduced prior to attaching a top film of opaque ink or equivalent material that is scrapable with a sharp hard object into small disintegrating particles from the plastic carrier.
  • Object of the present invention is the cost-effective production of a largely pre-produced rubbelbaren label in the form of, for example, rolls, which are provided prior to application to cards or printing units, at least by means of computer-generated hidden information.
  • the computer-generated information is introduced by means of a Nd: YAG laser beam or a thermal printing unit or with a mechanical printing unit.
  • conventional opaque layers including a conventional graphic design, are transparent to the 1064 nm wavelength of an Nd: YAG laser beam.
  • Nd: YAG laser beam With a suitable choice of a layer underneath with corresponding NIR laser initiators, such information can be irreversibly inscribed without infringing the opaque overlying scratch-off layer.
  • the information can be done in a layer as well as in or on a slide.
  • the control of the type of information input can be done on the one hand by the laser power as well as by the nature of the focus.
  • a very well-known type is the surface color change due to the action of a laser beam.
  • a carbonization ie a carbonization, can be used to produce a high contrast and / or gray values.
  • a largely transparent or translucent film with matrix-like distributed laser initiators can be used.
  • information can be introduced in the interior of such a film, and the contrast is usually improved by arranging a layer of highly reflective material or of a highly reflective color below such a film.
  • This may be a white plastic film as well as a paper or thin board carrier.
  • print layers in which case the sequence of layers is titanium dioxide white or ZnS white with an underlying silver layer.
  • Such a layer sequence has the additional advantage that the laser information introduced can not be read from the underside of the rubbelbaren label.
  • Another method for producing the hidden and optionally the visible information is the laser ablation according to the prior art.
  • a removal can take place on the surface and a positive or negative contrast can be produced.
  • it is also possible to use a so-called internal ablation according to the prior art (compare Schreiner EP 00 866 750 B1 with a laser-inscribable film). This has in combination with the NIR-transparent rubbelbaren layer the advantage that the surface of the label remains undamaged and the information is covered and is thus well protected against all possible environmental influences.
  • FIG. 1 shows a schematic representation of a rubbelbaren label (1) with an opaque substrate (4) is shown.
  • a film combination of the opaque substrate (4) with a bonding agent layer (5) and a release liner (6) is used, wherein the release liner (6) has the function as a carrier film or release film and that with the boundary (14) Contoured label (1) provides for an application.
  • Such a film combination (4, 5, 6) is usually used in multiple use or in roll form.
  • the adhesion promoter layer (5) is chosen such that a desired adhesion to the application surface, ie a paper surface, a Thin cardboard surface or a plastic surface is ensured.
  • the application can be carried out by peeling off the peel-off film (6) and pressing or by means of thermal activation or in principle also by wet bonding.
  • Unwanted detachment can thus be achieved by the adhesive effect in conjunction with the application surface.
  • the substrate (4) can also be made microperforated or microstructured, so that during a detachment attempt, the substrate (6) disintegrates into individual parts and thus removal without destruction is not possible.
  • the surface or the upper area of the substrate (4) must be designed to receive the computer-generated information (2) or (13) in accordance with the respectively selected printing method.
  • the surface of the substrate (4) must be made laserable.
  • blackening or grayscale can be generated and color contrasts according to the state of the art can also be generated with a corresponding choice of surface.
  • Such information (2, 13) produced in this way are irreversible and have a good resistance to environmental influences and are furthermore very resistant to the stresses when scraping off the rubbelable layer.
  • the rubbelbare layer (3) for the laser beams usually 1064 nm of a Nd: YAG laser, must be transparent, which experience has shown that there are some 100 micron thick white opaque layers or what also applies to conventional inks.
  • usually no electrically conductive layers or layers of silver paste or metallic diffractive layers can be used, as these usually absorb the laser beam so strongly that there would be a visible change and thus no hidden information (2). would be writable.
  • the surface of the substrate (4) for a thermal printing process must be formed appropriately.
  • this method is used, which provides a relatively high temperature for irreversible color change according to the prior art, which remains stable under normal environmental conditions.
  • the rubbelbare layer (3) must be thermally stable and thin enough and / or thermally well conductive in this case, so that a rapid printing with a required resolution of usually 200 to 300 dpi is possible.
  • the resolution is usually given by the machine readability of the information (2, 7) and is based on experience when using barcodes in the range of about 200 to 300 dpi, but may be in large labels (1) even below 100 dpi.
  • the realization can be done very easily by means of thermal printing units according to the prior art, wherein preferably the temperature of the printing unit on the label to be printed (1) must be set and thereby typically up to 180 ° C and above used and here the rubbelbare layer (3 ) is usually performed as shown in Figure 2, in a sandwich-like design (8, 3) is executed and so on the surface of the layer (3) no recognizable information is visible.
  • this design (13) can be applied over a large area in multiple use, as well as in the strip utility in roll form (15) or in the individual use (1).
  • the surface of the substrate (4) for a mechanical printing method must be formed appropriately.
  • a method is used for this purpose, which causes an irreversible color change according to the prior art by the burden of a dot matrix printer or a daisy wheel printer, which remains stable under normal environmental conditions.
  • the rubbelbare layer (3) must be designed stably in this case against the mechanical action, so that on the surface of the layer (3) no visible change is given. Conversely, the layer (3) must allow a sufficiently fine and accurate introduction of the information (2, 7). For this purpose, coatings or layer systems according to the prior art are provided.
  • FIG. 2 shows a schematic representation of a rubbelable label (1) with an opaque substrate (4) and a double scratch-off layer (3, 8).
  • a rubbelbare layer 3, 8
  • an optimal manufacturing process must be found, which ensures a good quality of coverage against visual and mechanical reading attempts.
  • the NIR transparency for the case of laser marking and / or the thermal suitability for a thermal printing unit and / or the mechanical properties for a mechanical printing unit must be met.
  • the upper layer (8) consists of a thin film and contains a rubbelbare lower layer (3).
  • such a sandwich-like Scratch composite (3, 8) is often microperforated or microstructured or scribed according to the prior art by means of laser cutting or special punching and is achieved in that in the case of a detachment attempt this leads to a destruction of Rubbelverbundes (3, 8) or to a clearly visible damage.
  • FIG. 3 shows a schematic representation of a rubbelable label (1) with a largely transparent or translucent substrate (4) and a plurality of underlying layers (9, 10, 11).
  • This embodiment naturally provides good protection of the hidden information (2) and the visible information (7) through the film (4) above, which is usually made very thin and made, for example, of PET or PP or PE or PMMA or generally of a transparent one Thermoplastic plastic exists.
  • an information layer (9), an opaque reflective layer (10) and usually a second opaque layer (11) are arranged on the underside of this thin film (4).
  • This second optional layer (11) is usually carried out in the form of a silver paste printing and is thereby ensured that no reading of concealed information (2) is possible.
  • the opaque layer (10) is usually made in white color based on titanium dioxide or ZnS filled polymeric layers.
  • the layers (9, 10, 11) are produced in the form of thin layers by screen printing, flexographic printing, offset printing, gravure printing or by doctoring or roller coating. However, these layers can also be made from thin films or coextruded film combinations.
  • the information layer (9) must be set sensitive for the particular printing process provided.
  • FIG. 4 shows a schematic representation of a rubbelbaren label (1) with a substantially transparent or translucent substrate (4) and an underlying adhesive layer with information elements (12).
  • a substantially transparent or translucent layer (4) or a substrate film (4) can be combined with a sensitive adhesion promoter layer (12) and the carrier film (6) as a sandwich.
  • the sensitivity of the layer (12) is set for the particular printing method used, that is to say laser-sensitive, thermally sensitive or pressure-sensitive.
  • the layer (12) can be made opaque.
  • a graphic design (13) can be introduced between the layer (12) and the substrate (4).
  • FIG. 5 shows a schematic representation of a label roll (15) with rubbelbaren labels (1) including the boundary (14) is shown.
  • rollers (15) are made from a multiple use.
  • the arrangement shown is exemplary only and may be customized to a variety of types and be formed. In particular, larger or smaller scratch pads (3, 8) can be formed with a wide variety of shapes.
  • very thin layer combinations (8, 3, 4, 9, 10, 11, 5, 12) can be used, since the manipulation takes place via the usually relatively stable carrier film (6).
  • the boundary (14) can be effected by lasering, punching, in particular in the form of a steel strip section, in such a way that the complete rubbelbare label (1) is produced bordering on the carrier film (6) (14) and thus removed from the carrier film (6) can be and can be applied to a desired position of a telephone number card, a lottery ticket or generally on a promotional item.
