Definitions

  • the invention relates to a multilayer identification card with at least one card surface made of plastic, which in some areas has characters or symbols in a relief structure that can be used as a printing block, and to a method for producing such identification cards.
  • ID cards in the form of credit cards, bank cards, cash payment cards, authorization cards or the like are used in a wide variety of areas, such as. B. include cashless payments, access control systems and a wide variety of service systems. These ID cards generally have data related to the cardholder, which are applied in the so-called personalization process. A common form of the possible representation of these characters is the embossing, in which the user-related data are embossed in relief from the back of the ID card to the front of the card. To make the individual characters more visible, they are additionally colored in their apex areas.
  • this form of personalization is used more widely, particularly in the case of credit cards, since the character set which can be used as a printing block allows the data to be transferred easily from the card to the current payment slip. So-called imprinters are used, in which the card and the payment slip are inserted.
  • the user data is transferred to the payment document via a mechanical embossing process using carbon or carbon paper (DE-PS 20 18 927).
  • An internationally defined standard determines, among other things, the location of the embossed data on the ID card, its shape and its relief height (ISO standards 7811/1 and 7811/3).
  • the embossed data appear only on a card surface.
  • the personalization data are embossed in metal plates and transferred to the card surface when the ID card is laminated.
  • the card material softens and flows into the depressions in the metal plate without leaving a negative relief on the back. This creates an embossing in which the characters can no longer be embossed.
  • this method is much more complex than the usual embossing method, since a metal plate with the correspondingly engraved personalization data must be produced for each card and this personalization process is a process step that cannot be separated from the card production.
  • DE-OS 32 13 315 Only through DE-OS 32 13 315 was an identification card and a method for producing the same presented, with which identification cards can not only be provided in a simple form with characters that can be used as a printing block, but in which these characters are also available in a particularly forgery-proof form .
  • a laser beam is preferably used for this purpose, which generates the heat necessary for triggering the foaming process or activating the blowing agents in this foamable plastic material.
  • this foaming process can be carried out in a targeted manner in order to produce the characters in accordance with the standards with regard to their dimensions and their relief height.
  • this foaming can be associated with discoloration of the plastic material, so that the previously necessary coloring process is unnecessary. Since the discoloration takes place in the plastic material itself and is also irreversible, it is forgery-proof and resistant to abrasion.
  • the invention is therefore based on the object, while maintaining the simple, in particular given by the laser process, but forgery-proof, individual labeling option, to provide an identification card which can be equipped with a standard embossed character set even without the use of special foamable foils.
  • the invention is based on the idea of using the "natural foamability" of plastic materials generally used in identity cards, such as PVC and polycarbonate, which can be caused by laser action in order to achieve a relief height sufficient for a clear imprint of the characters and the total height of the embossing characters required according to the standard to be realized above the rest of the card surface by an additional deformation of the card body in the area of the embossed character.
  • plastic material such as. B. PVC
  • this increase in volume caused by the gas bubbles is now used in a targeted manner to generate characters which are not only apparent in color but also in their relief height in relation to the surroundings.
  • plastic material such as. B. PVC
  • Appropriate optimization of the material and process parameters can therefore be used to generate characters in a relief height sufficient for an impression, the surface in the character area being influenced only imperceptibly and, in particular, still being completely self-contained is.
  • the last-mentioned characteristic is of particular importance for the quality of the later reprint of the data. Only at very high intensities does the formation of the gas bubbles lead to bursting in the cover film, as is known from the aforementioned DE-PS.
  • the effective maximum height of the sign in relation to its immediate surroundings does not necessarily have to be the 0.46 mm specified by the standard.
  • a relief height of approximately 100 ⁇ is already sufficient for a mechanical impression of relief signs.
  • This relief height is now achieved according to the invention with the abovementioned laser inscription, preferably by means of a corresponding increase in volume in the transparent cover film of the identity card, while the relief height (360 über) above the surface of the card which is still missing in order to meet the norm is produced by deforming the card to form plateaus becomes.
  • a double-layer transparent cover film is preferably used for the identification card according to the invention, a plastic material being used for the outer layer, which is somewhat less sensitive to the laser effect. This ensures that the outer film softens, but the formation of bubbles is somewhat less than in the more sensitive inner film. The outer film can then evade the inner pressure resulting from the formation of bubbles, itself also contributes to the increase in volume, but is subjected to a somewhat less thermal load in view of a good surface quality.
  • the plateaus on which these characters are formed by means of laser can certainly cover a larger area, e.g. B. the area of one or more lines of characters or they can also be composed of a plurality of smaller plateaus, each of which can only accommodate one character.
  • plateau formation e.g. B. a mechanical embossing, thermal embossing or embossing the card material while softening the material by means of a high-frequency alternating electromagnetic field.
  • the latter method has the advantage that, by appropriately designing the electrodes which simultaneously form the embossing stamp, the card only has to be thermally stressed in the areas which are actually to be deformed. As will be shown later, this fact can also be used to be able to carry out the plateau formation after the laser marking.
  • An important advantage of the present invention is that the usual materials known from card production can be used for the construction of the card, only the layer thicknesses required to achieve a sufficient relief height being observed.
  • the card manufacturing and personalization processes are also two completely independent process stages. Personalization can thus represent the last step in the production of ID cards.
  • the main advantages of this circumstance include: B. that in the card manufacturing "scrap cards" can be discarded before the personalization process or already personalized cards are no longer endangered by subsequent manufacturing steps.
  • the relief structures achieved by the natural "foamability" of the plastic material also have sufficient strength, which is necessary for the frequent later use in the above-mentioned imprinters for printing the user-related data.
  • the proposed card structure with the transparent double-layer cover film also allows other authenticity features, such as. B. the "laser tilt image” known from DE-OS 36 34 865 or the “parallax image” known from DE-OS 36 34 857 by laser.
  • a font without a relief structure can also be generated, the intensity and the scanning speed of the laser beam having to be controlled accordingly in a manner to be explained later.
  • a font with a relief structure would have a negative impact on the readability of the magnetic data, since transport rollers arranged in this area impair the smooth card transport.
  • an identity card 1 and 2 show an identity card 1, such as. B. a credit card with the information content typical for them. This is e.g. B. the specification of the issuing credit institution 2, the z. B. be applied by printing to the card ticker. Furthermore, the card has an authenticity feature 3, such as. B. a hologram embedded or glued into the cover film.
  • the areas 4a and 4b of the card are reserved according to the international standard for the embossed characters 5, which are usually introduced in the area 4b in three or four lines (for the sake of simplicity, only one line is shown in the drawing). These characters are created after the card has been made. H. after welding the individual card layers, stamped in a corresponding embossing press. For better visual visibility, the characters are then displayed in their raised areas, i.e. in the crown areas 6, colored.
  • FIG. 2 shows the map in a sectional view with a two-layer structure shown here by way of example.
  • An opaque card core 7 carries z. B. one or both sides of a printed image 8 and in the back of a magnetic strip 9 is embedded.
  • an electrical circuit (not shown in the figure) can be embedded in a cutout in the card core.
  • the embossed characters 5 were introduced by pressing them in from the back and correspondingly deforming the card body, the card being deformed to such an extent that the apex regions 6 reach a height H of approximately 0.45 mm above the card surface.
  • the identification card is also embossed, but in this embossing it is not the characters themselves that are introduced, but only partial regions 21a, b into which the embossed characters are to be introduced in order to be uniform 1 4th Raised 0.35 mm above the card surface.
  • Areas marked 21a and 21b are hereinafter referred to as plateaus. You can e.g. B. have the size of a line or a multi-line field. These plateaus now serve to achieve the effective relief height of the embossed characters of 0.46 mm as required by the standard.
  • Fig. 4 shows the semi-finished product 20 of the identity card in the sectional view.
  • the card according to the invention has a three-layer structure. These three layers 22-24 are the opaque core layer 22 and a two-layer transparent cover layer 23, 24.
  • the core layer can, as previously mentioned, be provided on one or both sides with printed images 25, 26 and also carry other security features, such as, for example, B. a security thread, watermark-like effects or other features that serve to protect against forgery of the card structure.
  • This opaque core layer 22 is covered on one side by a one-layer, but preferably two-layer transparent cover film which is matched to the laser inscription in terms of the choice of material.
  • the two-layer cover film consists of two transparent PVC layers 23, 24, which have an improved absorption capacity compared to the laser beam exhibit. Such films are such. B. from the previously mentioned documents DE-PS 31 51 407 and DE-OS 36 34 857 known.
  • a film is selected which is more sensitive to the laser beam than the outer cover film 24.
  • This card can be completely finished, ie printed, laminated and embossed, so that the necessary data only have to be added as a last step in the context of personalization.
  • the back of the card can also be covered with a transparent cover film, equipped with a magnetic strip and / or an integrated circuit.
  • the data which can be introduced by means of a laser are introduced into the card, the embossing marks 28 being recorded in the plateau region 21 (FIGS. 5, 6).
  • the laser beam 29 is guided correspondingly over these plateaus 21a, b of the card 19 to form the characters, the recording parameters such as intensity, scanning speed, pulse frequency etc. being selected such that the greatest possible formation of bubbles 30 results with simultaneous softening of the film, without causing sharp bursts and pronounced crater formation in the surface area.
  • a so-called gray wedge can be recorded in a trial run, on the basis of which the optimal laser parameters can then be determined empirically.
  • a layer thickness of 100 to 150 150 is preferably selected for the inner cover film 23 and a thickness of 150 to 200 ⁇ for the outer cover film 24.
  • This overall 250 to 350 ⁇ thick transparent cover film can be expanded to a thickness of 350 or 450 ⁇ by appropriate laser exposure. Because of the local limitation of the "foaming" area, an increase in volume of approximately 30% is directly reflected in a corresponding change in thickness.
  • the relief formation can be additionally optimized by means of an appropriate laser beam guidance.
  • the laser operated in pulse mode is guided over the card surface in such a way that the successive pulses overlap locally.
  • the effect of the laser beam on the material is thus increased with the intensity remaining the same, since the following pulse strikes partially blackened and thus more absorbent material.
  • the same card structure also allows the identification card to be labeled without simultaneously creating a relief. It is important to ensure that the intensity of the laser beam is reduced in this way and that the recording is preferably carried out without overlapping the individual laser pulses that - as is known from DE-OS 36 34 857 - only a blackening in the more sensitive inner cover layer and essentially there are no visible bubbles.
  • This labeling method is particularly suitable for labeling the area of the card in which the magnetic stripe is located on the back, since here a surface that is smooth on both sides is necessary for scanning the magnetic stripe. Usually concerns this is the information provided by the institute 31.
  • the data is preferably recorded by scanning the card surface in accordance with a dot or line matrix, in which the laser beam is guided line by line over the card and the character is generated by correspondingly fading the laser beam on and off at the corresponding matrix points.
  • a dot or line matrix in which the laser beam is guided line by line over the card and the character is generated by correspondingly fading the laser beam on and off at the corresponding matrix points.
  • the card 19 shown in FIG. 5 also has a visually verifiable authenticity feature 27, which is also generated with a laser and whose appearance can change depending on the viewing angle.
  • authenticity features are known from the documents, DE-PS 36 34 865 and DE-OS 36 34 857, the disclosure of which reference is made here. It is precisely here that the versatility of laser marking can be seen, which allows data with both the same relief and relief and corresponding visual authenticity features to be created with the same card structure by simply changing the laser control or intensity, possibly combined with a partial embossing (plateau, lens grid) Insert card.
  • Fig. 7 shows a further embodiment, in which the plateau 21 each has only the size of a character 28 and a plurality of plateaus placed next to each other are embossed on the card. If technically justifiable, the number of individual fields can also be adapted to the respective number of characters required for the card-specific lettering.
  • the individual plateaus or the large-area plateaus shown in the aforementioned examples can be achieved in a variety of ways.
  • An embossing method is preferred in which the plastic material of the card 41 (FIG. 8) is softened by the action of a high-frequency electrical field and is deformed by appropriate embossing molds.
  • the embossing molds can be electrodes 40a, b for the alternating electrical field.
  • the processing of PVC with the help of high-frequency alternating electrical fields is e.g. B. known from the general literature.
  • This deformation technique has the advantage that the card is only thermally stressed in the areas to be effectively deformed. Furthermore, this deformation is difficult to recover, since, in contrast to the mechanical cold deformation, this is a deformation "without memory”.
  • the HF deformation also allows the plateaus to be formed even after the laser marking has been formed.
  • the embossing stamp 40a has a cutout 42 in the card area which carries the already lasered relief data 43, so that the mechanical effect of the embossing stamps is concentrated only on the edge regions of the plateau to be formed.
  • the lasered relief data therefore remain undamaged during the embossing process and this allows the embossing to be carried out even after the laser inscription.
  • This solution thus has the further advantage that in the case of laser marking, in which the cards are automatically separated, transported and stacked, it is possible to work with flat cards.
  • the embossing stamps used in the aforementioned deformation techniques can additionally have a relief in their surface, whereby an embossing pattern (32, FIG. 5) is embossed into the card surface at the same time as the plateau is formed.
  • This embossing pattern can e.g. B. represent a micro relief, texturing, a sequence of characters, logos or similar symbols.
  • the map thus contains a further feature that makes replication or modification considerably more difficult, especially if a self-contained pattern runs over the entire plateau area and is only interrupted by the lasered relief symbols.
  • the multilayer card body 50 is provided with an additional film piece 51 in order to form the plateaus in the embossed area.
  • This embedded between core and cover sheet 53 or 54 piece of film 51 can, for. B. be a film of the same transparent material as the inner cover film layer of the embodiment shown in Fig. 4 or 6. This increases the thickness of the map by about 0.3 to 0.4 mm in the required range.
  • the characters with the relief structure are then formed by means of, as already described above a laser beam, the volume being increased by the formation of bubbles combined with a simultaneous discoloration in these transparent layers.
  • This additional piece of film 51 can, however, also be glued to the outer surface of the finished card or welded onto the card.
  • the two-layer cover film structure shown in FIG. 4 is recommended as the material for this additional film.
  • the intensity of the laser beam can be controlled in such a way that the card core is at least blackened in its surface and the user data can also be recognized on the card core layer.
  • the plateau formation by means of an additional piece of film has the advantage that the back of the card remains completely flat and thus a printed image on the back of the card is not disturbed by impressions. In addition, the plateaus gain stability due to this flat back of the card.
  • the support surface for the card in the imprinter devices could be provided with support elements which engage in the cavities on the back of the card and the plateaus during the printing process support.
  • the embossing dies or laminating plates in the plateau area on the back of the card are additionally equipped with depressions in the form of bores, channels, etc., into which the softened card material can flow during the formation of the plateau.
  • FIG. 10 schematically shows such a card 60 with a plateau-like elevation 61 on the front of the card, which is supported on the back by a support profile 62 in the form of support rails 63 which run through the negative structure.
