Definitions

  • the invention relates to a method for the production of information-bearing plastic carriers according to the preamble of claim 1.
  • the product produced by the method according to the invention consists at least partly of plastic and carries on one of the plastic surfaces permanently visible information which can be found there and which may appear on the carrier alongside other visible information or on its own.
  • this product is two-dimensional in the sense of a body that has the thickness of a sheet or a card.
  • Examples of such execution Types of the invention are so-called identity cards, including credit cards, which are issued by the banks to their account holders.
  • the product according to the invention consists of the plastic carrier which, in addition to other information originating from the bank or from the card manufacturer, bears at least the signature of the bank customer, which is produced by the method according to the invention.
  • Identity cards and these corresponding embodiments of the invention are often only a section of a rigid PVC plastic film; on this the user of the card can emboss certain information on the back of the card which then appears raised on the front of the card.
  • Such two-dimensional carriers often have a writing field ' on which the card surface is printed, so that it can be labeled differently than the smooth plastic surface.
  • Demanding identity cards consist of a laminate which has at least two transparent plastic film cutouts, the so-called overlay and often two paper or plastic cutouts, the so-called inlet, which are connected to one another with the help of pressure and heat to form an insoluble unit so that the plastic films are on the outside lie and cover the cutouts of the inlet.
  • These information cards can also be provided with the above-mentioned entered information, but usually allow information printed on the papers to be recognized through the transparent plastic surfaces.
  • the product according to the invention is designed in the manner of the identity cards described above, then at least one of the cards is on one.
  • Information appearing product produced by the inventive method As far as further information is available, it can be done in a conventional, i.e. in particular in the manner described above, either by the user or by the manufacturer of the card.
  • These and other products according to the invention are primarily concerned with the security against forgery of certain information which reflects the user of the product, but in particular the personal data of a cardholder. This data can also include an image of the cardholder. In particular, however, it is a matter of forgery-proof reproduction of the signature of the cardholder or card user on the product immediately after the person concerned has signed.
  • the production of the last-mentioned products in particular is subject to conditions other than the application of data to the two-dimensional carrier before the method according to the invention is applied, because this information is either printed on or applied with the aid of embossing templates.
  • the invention is based on a previously known method, which is used in particular for the production of information-reproducing plastic carriers is used, which serve as identity cards and, as a rule, a signature is permanently attached to the carrier as the last manufacturing process and must remain visible. This process is usually carried out by a card user who is a card user. manufacturer that usually receives two-dimensional cards printed with general information and often even has to provide the personal data of the cardholder.
  • the non-memorable information i.e. in particular the customer's signature with an ink, i.e. attached to the support with a pen or ballpoint pen and thereby reproduced.
  • a carrier can be made tamper-proof.
  • One of the previously known methods (DE-PS 28 01 015) consists of a certain sequence of printing and overprinting and is based on a fluorescence visible in UV light and / or a change in the text field that becomes visible in natural light.
  • the previously known method has disadvantages, just like the possibilities of counterfeit protection that have become known so far. For example, it is difficult to identify and subsequently add to a signature made in the presence of a representative of the card user shut down.
  • the type and scope of the information that can be provided by the user are also limited or the user must have correspondingly complicated manufacturing devices available when the information content is expressed.
  • the invention has for its object to perform the known process so that the manufacture of the two-dimensional carrier provided with the information is simple to tamper-proof and with any information reproduction on two and three-dimensional carriers.
  • novel starting substrates are used to produce the plastic carrier that visibly reproduces the information.
  • this is an ink or printing ink, which, due to its dark, heat-absorbing composition, can be heated with the light from discharge lamps or CO 2 lasers and reaches temperatures which are short-term duroplastic, but above all thermoplastic, preferably hard PVC can melt and / or melt; the cooling of the ink or printing ink that then occurs does not reverse this process. so that the ink or printing ink trace is retained in the plastic carrier.
  • the heat portion of the light of a discharge lamp is used as the substrate, the illuminance and the duration of the illumination being matched to the composition of the ink or printing ink and to the plastic in such a way that that for local melting or melting of the plastic necessary temperature is reached, but on the other hand the remaining surface of the plastic does not experience any changes due to the heat of the light.
  • the process according to the invention only acts on these substrates in such a way that even when the ink or printing ink described is irradiated over the entire surface, only the information is burned in with the aid of the heat component of the lighting and is thereby fixed in the plastic carrier.
  • the product manufactured in this way is absolutely counterfeit-proof because the burn-in cannot be imitated or changed. Depending on the volume of the plastic melt, this also contains components of the ink or printing ink that have melted down.
  • the information can therefore appear on the product according to the invention in any reproduction possibility that can be achieved by lettering, drawing or printing.
  • the information fixation does not require more than one lighting device, which, however, should preferably have automatic control of the exposure time and the lighting parts.
  • the method according to the invention can also be used to reproduce signatures on identity cards which cannot be changed subsequently or which can be supplemented by unauthorized persons, because the information also saves the heat-storing property of normal ink from the heat-absorbing printing ink and thus distinguishes it from it.
  • the method according to the invention can therefore be carried out on identity cards in such a way that the cardholder has his signature on the plastic surface does what is then fixed in the manner described. It is possible to visualize certain information or information that has been entered by hand before the lamination in a printing ink or by the card manufacturer, which can also consist of a grid. If, for example, the printing ink has been applied to a signature field of the card behind or below the described front side in an open print, e.g. a special print image (raster), the plastic can be melted with this printing ink and the signature field on the outside of the plastic film can thus not be labeled be made. This effect can of course also be achieved by applying the printing ink to the outside of the plastic film in the signature field.
  • the illumination used to fix the information is always from the outside, except when using CO 2 lasers. and acts on the plastic carrier from one side, but in any case without contact, the dimension of the plastic carrier plays no role in the applicability of the method according to the invention.
  • the method according to the invention can serve to permanently and counterfeit-proofly fix information that has been applied with the printing ink or ink to a video cassette, for example a logo date or a rental date, simply by exposure to light.
  • the embodiment of the method according to claim 2 relates to a group of Types of execution in which the information is fixed by covering a full-surface or light print of the heat-absorbing printing ink (or ink and by omitting the action.
  • the print can be applied to the outside of the plastic surface, but in the case of laminates also to the inside of the plastic surface. In the case of laminates, however, in view of the better printability of paper, the print will be applied to at least one of the visible paper sides which are covered after the lamination of the plastic film remains completely smooth, which may make counterfeiting attempts even more difficult.
  • a pressure from the heat-absorbing paint is applied to the support in such a way that the burnings follow a light print pattern.
  • the information is applied directly to the carrier forming the starting substrate either by labeling, drawing or printing.
  • the information is applied without contact because a transparent template is used. This procedure allows extensive and complex information, such as the reproduction of transparent images or drawings on the described laminates or simple plastic cards, to be fixed in a permanent, forgery-proof and visible form.
  • the inks or printing inks required for such processes can be adapted in different ways to the melting properties of the plastic carriers which form the starting substrate for the process according to the invention by changing their respective composition. According to claim 6, this is done according to the invention in such a way that the plastic material is melted only slightly where it is exposed to the action of the heated paint or ink, so that there is only a depression on the surface of the plastic exposed to heat trains. This method is useful for identity cards if the card surface is to remain smooth. Even if you use this procedure on the card surface, the information is tamper-proof. Because the subsequent one Removal of the burned-in ink or printing ink leaves the depression and thus the information on the plastic surface.
  • the invention also offers the possibility of adjusting the ink or ink.
  • Ink composition on the melting properties of the respective plastic in the carrier so that the plastic, especially if it is a thermoplastic, expands at the point of heat, which can either lead to a raised reproduction on the plastic surface in question, which the heat is directly exposed or the information is also fixed on the opposite surface of the plastic film, i.e. is burned in from the back on an identity card and appears raised on the outside.
  • the heat absorbing inks or inks will adhere to the plastic after exposure to heat, i.e. be melted into it.
  • this does not mean that the information itself must also be received in the form in which it was applied to the plastic carrier.
  • the ink or ink used for covering can also be removed again after the burning-in process, for example by wiping.
  • the method according to claim 8 can also be carried out in such a way that the information is burned into an opaque plastic surface of a three-dimensional carrier, including Video tapes fall.
  • FIGS. 1 to 3 A credit card 1 is shown in FIGS. 1 to 3, the front side of which depicts FIG. 1.
  • the card consists of a laminate, which in turn is composed of two hard PVC foils 2, 3 and two inlet 4, 5. In FIG. 2 the laminate is in the correct assignment of it. Individual parts, but not yet shown welded.
  • the front of the card shown in Fig. 1 is 6, the back is 7.
  • the transparent plastic film 2 carries an imprint 8 which appears on its front side, which shows the company locus at 9 and information about the card user at 10.
  • the information and the company logo o have been left out of ink 8.
  • the border 9 or 10 of a signature field 11 is printed on the outside of the film 2 in the same printing ink.
  • the references to the account numbers and the card number are printed in 12 in the same ink as information 9, 10 and 11. These prints are already made by the card manufacturer.
  • a label 13 appears on the front paper laminate 4, which later makes the account number and the card number on the front side 6 recognizable at 14 and 15 due to the transparency of the film.
  • the label 13 is removed by the user before the account card is laminated appropriate.
  • the second paper cutout 5 contains detailed information about the use of the card, which is shown schematically at 16 and also appears on the back after lamination due to the transparency of the plastic oil 3.
  • This plastic film carries a printed, magnetizable layer 17 on its outside. Magnetic information is recorded in this layer.
  • the customer When issuing the account card, the customer makes the signature shown at 18 on the signature field 11 surrounded by 9 and 10. This is done in normal ink, which can later be easily wiped off from the smooth plastic surface 19 of the transparent film 2 again. Before this happens, the signature is fixed.
  • the paper cutout 4 bears on its surface 20 facing the plastic film 2 an imprint 21 made of a clear, open print, which can be punctiform, for example.
  • the printing is carried out in a printing ink which has a dark, heat-absorbing composition.
  • Such printing inks are known per se.
  • the printing ink used depends, on the one hand, on the melting properties of the plastic in the film 2 and, on the other hand, on a discharge lamp (not shown) tuned what heat provides.
  • the discharge lamp is expediently housed in a box into which the account card 1 is inserted after signature, so that the front 6 is exposed to the illumination by the discharge lamp.
  • This device should expediently be provided with a timer which automates the ejection of the card after a period which is fixed due to the heat-absorbing properties of the printing ink.
  • the printing ink in the print 21 and the signature ink heat up.
  • the print 21 is covered with the ink of the signature 18, the print 21 is heated up more by the heat of the signature and, in addition, heats up comparatively less.
  • the exposure time of the discharge lamp light is determined in such a way that the uncovered parts of the pressure 21, with the heat absorbed by them, cause burns, which are shown schematically at 22 and 23 in FIG. 3.
  • Each of these burnings has a correspondingly shaped recess 24 and a filling 28, which consists of the fried plastic material and the remnants of the printing ink of the print 21, which have gone into the plastic and are accordingly no longer found on the paper 4.
  • the portion of the printing ink which was covered with the signature and is designated 29 in FIG. 3 is drawn on the paper. This means that the signature after wiping the ink comparatively stronger than the burn-in 22, 23 of the Plastic film 2 is baked (not shown). The surface 24 of the identity card, however, has remained completely smooth.
  • the paper 4 in the initial state also bears a print 30 in the area of the signature field 11, but this only marks the signature field.
  • the signature 18 in the signature field 11 was carried out with an ink which has the dark, heat-absorbing composition described. After the method described has been carried out, the signature is found in the form of a stoving 31 on the upper side 24 of the film 2. It appears raised there as a result of the ink fritted with the plastic. Even if these parts are removed, a depression 32 remains, which makes the attempt at forgery immediately visible.
  • the laminate is welded from parts 3 to 5 before the signature service after the information 14 and 15 has been applied by the card user and then submitted for signature.
  • the manufacturing process described also allows the laminate to be welded by the card manufacturer and the card user to be sent the finished welded cards. Then the information 14 and 15 can also be used by the card user in the described Ink or printing ink with a heat absorbing composition must be entered in the presence of the customer.
