Abstract

An identity card, e.g. a cheque card or credit card, usually has a space in which the card user writes his signature when the card is issued. A weak point, as far as manipulations of the cards are concerned, has long been that the signature space could be eliminated and replaced by a counterfeit signature space. According to the invention, in order that such manipulations are easily recognisable and forgeries are consequently made more difficult, the security typography (guilloche print) which anyway covers the area surrounding the signature space is extended on without transition over the signature space also. If the counterfeiting of a signature space provided with such security typography is itself extremely difficult, it is practically impossible to arrange the security typography in such a manner that it passes continuously from the signature space into the area surrounding the signature space. <IMAGE>

Description

Die Erfindung betrifft eine Ausweiskarte nach dem Oberbe­griff des Anspruchs 1 und ein Verfahren zum Herstellen einer solchen Ausweiskarte.The invention relates to an identification card according to the preamble of claim 1 and a method for producing such an identification card.

Ausweiskarten der hier in Rede stehenden Art sind zum Beispiel Scheckkarten, Kreditkarten, Mitgliedskarten und dergleichen, wobei der Kartenaufbau in der Regel der ISO-­Norm 7813 (DIN 9781) entspricht.Identity cards of the type in question here are, for example, credit cards, credit cards, membership cards and the like, the card structure generally conforming to ISO standard 7813 (DIN 9781).

Derartige Ausweiskarten sind zum Beispiel als mehrschich­tige Kunststoffkarten ausgebildet. Auf der Vorderseite der Karte befinden sich allgemeine Informationen, wie z. B. der Name eines Kreditinstituts sowie benutzerbe­zogene Informationen, wie z. B. der gedruckte Name des Benutzers, dessen Kontonummer, die Kartennummer und der­gleichen. Außerdem ist auf einem speziell dafür vorgese­henen Unterschriftsfeld die Unterschrift des Benutzers vorhanden. Üblicherweise wird bei der Aushändigung der Karte der Benutzer gebeten, seine Unterschrift in das dafür vorgesehene Unterschriftsfeld zu setzen.Identity cards of this type are designed, for example, as multilayer plastic cards. There is general information on the front of the card, such as: B. the name of a credit institution and user-related information such as B. the printed name of the user, his account number, the card number and the like. In addition, the signature of the user is available on a specially provided signature field. When the card is handed over, the user is usually asked to put his signature in the signature field provided.

Um Fälschungen und Verfälschungen vorzubeugen, werden die Ausweiskarten in einer Weise hergestellt und ausgestal­tet, die ein Nachahmen einer Karte und/oder eine betrü­gerische Manipulation der Karte ausschließen soll.In order to prevent counterfeiting and falsification, the identification cards are produced and designed in a way that is intended to preclude imitation of a card and / or fraudulent manipulation of the card.

Zu den Sicherheitsmaßnahmen gehört einmal der Kartenauf­bau selbst. Beispielsweise wird durch einen mehrschich­tigen Kartenaufbau aus Kunststoff, bei dem die Daten im Karteninnern der miteinander unter Anwendung von Wärme und Druck verschweißten Schichten ein direkter Zugang zu den Daten und damit deren Verfälschung verhindert.One of the security measures is the card structure itself. For example, a multi-layer card structure made of plastic, in which the data inside the layers of the layers welded to one another using heat and pressure prevents direct access to the data and thus its falsification.

Ein weiteres Sicherheitsmerkmal ist ein sogenanntes Si­cherheitsdruckbild, üblicherweise ein Guilloche-Auf­druck, möglicherweise aber auch ein Logo, ein Mikrodruck aus Buchstaben- und Zahlenfolgen und dergleichen. Derar­ tige Sicherheitsdruckbilder dienen insbesondere aufgrund ihrer komplizierten Gestaltung dazu, sowohl Totalfäl­schungen - also komplette Nachbildungen - als auch Ver­fälschungen zu verhindern.Another security feature is a so-called security print image, usually a guilloche print, but possibly also a logo, a microprint of sequences of letters and numbers and the like. Derar Due to their complicated design, security print images serve to prevent total counterfeiting - that is, complete replicas - as well as falsification.

Häufiges Objekt derartiger unrechtmäßiger Manipulationen ist die auf der Karte befindliche Unterschrift des recht­mäßigen Besitzers. Um Verfälschungen, d. h. Manipulatio­nen, an diesen Unterschriften auszuschließen, muß also insbesondere das Unterschriftsfeld mit besonderen Sicher­heitsmerkmalen ausgestattet sein, um zu verhindern, daß jemand die Unterschrift des rechtmäßigen Ausweiskarten-­Benutzers entfernt und durch seine eigene Unterschrift ersetzt. Da die Unterschift in der Regel auf die Ober­fläche der fertigen Karte geschrieben wird, muß das Unterschriftsfeld einerseits die Tinte bleibend aufneh­men, andererseits so gestaltet sein, daß z. B. Radieren oder anderweitige Löschversuche eine für jedermann prüf­bare, vorzugsweise auffällige Veränderung des Unter­schriftsfeldes bewirken.The signature of the rightful owner on the card is a frequent object of such illegal manipulation. To prevent adulteration, H. Manipulations to exclude these signatures must, in particular, be provided with special security features in the signature field in order to prevent someone from removing the signature of the legitimate ID card user and replacing it with his own signature. Since the signature is usually written on the surface of the finished card, the signature field on the one hand has to hold the ink permanently, on the other hand it has to be designed so that e.g. B. erasing or other deletion attempts cause a testable, preferably noticeable change in the signature field for everyone.

Es sind verschiedene Verfahren und Maßnahmen vorgeschla­gen worden, um Unterschriftsstreifen gegen Fälschungen, d. h. hier: Nachmachen und/oder Manipulieren, zu sichern.Various methods and measures have been proposed to prevent anti-counterfeiting, ie. H. here: imitation and / or manipulation to secure.

In der DE-PS 27 56 692 ist eine Ausweiskarte beschrieben, auf die ein mit Stahltiefdruck versehener Unterschrifts­streifen aus Papier oder Kunststoff auf den Kartenkörper aufkaschiert ist. Da der Unterschriftsstreifen aufgrund des besonderen und komplizierten Stahltiefdrucks nur schwer nachahmbar ist, ist die Gefahr, daß der richtige Streifen durch einen gefälschten Streifen ersetzt wird, relativ gering.DE-PS 27 56 692 describes an identification card on which a signature strip made of steel or paper or plastic is laminated onto the card body. Since the signature strip is difficult to imitate due to the special and complicated steel intaglio printing, the risk of the correct strip being replaced by a counterfeit strip is relatively low.

Die DE-OS 16 46 225 zeigt eine Ausweiskarte mit aufge­klebtem Unterschriftsstreifen, welcher mit einem Sicher­heitsmuster ausgestattet ist, das bei dem Versuch, die alte Unterschrift zu entfernen, zerstört wird und einen Warnaufdruck (Void) freilegt. Grundsätzlich könnte man aber den zerstörten Unterschriftsstreifen durch eine Nachbildung ersetzen.DE-OS 16 46 225 shows an identification card with a glued-on signature strip, which is equipped with a security pattern that, when trying to remove old signature, is destroyed and a warning (void) is exposed. Basically, you could replace the destroyed signature strip with a replica.

Es ist auch schon vorgeschlagen worden, einen auf den Kartenkörper aufgedruckten Unterschriftsstreifen durch Verwendung spezieller Farben, zum Beispiel fluoreszieren­der Farben, fälschungssicher zu machen (DE-PS 28 01 015, EP-OS 176 403). Auch bei einer solchen Ausweiskarte könn­te eine ansonsten gültige Karte mit einem gefälschten Unterschriftsstreifen versehen werden. In der DE-PS 34 22 908 ist eine Ausweiskarte beschrieben, bei dem ein im Unterschriftsfeld zusätzlich vorgesehenes Hologramm den mittels Heißprägetechnik auf den Kartenkörper aufgebrach­ten Unterschriftsstreifen gegen Fälschungen sichern soll. Allerdings ist die Herstellung solcher Karten unter Ein­satz der Heißprägetechnik aufwendig und das Hologramm läßt sich durch ein entsprechend metallisch reflektieren­des Bild täuschend ähnlich ersetzen (Eindrucksfälschung).It has also been proposed to make a signature strip printed on the card body counterfeit-proof by using special colors, for example fluorescent colors (DE-PS 28 01 015, EP-OS 176 403). Even with such an ID card, an otherwise valid card could be provided with a forged signature strip. DE-PS 34 22 908 describes an identification card in which a hologram additionally provided in the signature field is intended to secure the signature strips applied to the card body by means of hot stamping technology against counterfeiting. However, the production of such cards using the hot stamping technique is complex and the hologram can be deceptively similarly replaced by a corresponding metallic reflecting image (falsification of impressions).

Außer den oben angesprochenen Versuchen, den Unter­schriftsstreifen fälschungssicher zu gestalten, gibt es noch Vorschläge, nach denen die Unterschrift bei Betrach­tung unter Tageslicht oder künstlichem Licht üblicher Lichtquellen nicht sichtbar ist und nur mit Hilfe spe­zieller Lichtquellen sichtbar gemacht werden kann, z. B. mit Hilfe einer UV-Lampe. Dies ist eine in vielen Fällen nicht akzeptable Einschränkung der Überprüfungsmöglich­keiten.In addition to the attempts mentioned above to make the signature strip tamper-proof, there are also proposals according to which the signature is not visible when viewed under daylight or artificial light from conventional light sources and can only be made visible with the help of special light sources, e.g. B. with the help of a UV lamp. In many cases, this is an unacceptable limitation of the options for checking.

In der GB-OS 2,040,807 ist eine Ausweiskarte beschrieben, bei der eine im Inneren des Kartenkörpers befindliche Mikrokapsel-Schicht durch Druckanwendung von außen z. B. mit einem harten Stift verfärbt wird und auf diese Weise die Unterschrift nachträglich in das Karteninnere einge­bracht werden kann. Durch den ständigen Gebrauch dieser Karte und der dabei unvermeidbaren mechanischen Bela­stung werden aber immer mehr Mikrokapseln zerstört, so daß die Karte eine unerwünschte Farbbildung zeigt.In GB-OS 2,040,807 an identification card is described in which a microcapsule layer located inside the card body by application of pressure from the outside, for. B. is discolored with a hard pen and in this way the signature can be subsequently introduced into the inside of the card. Through constant use of this Card and the inevitable mechanical stress are destroyed more and more microcapsules, so that the card shows an undesirable color formation.

In der US-PS 2,545,804 ist eine Ausweiskarte mit einem Papierinlett und beidseitiger Kunststoffbeschichtung be­schrieben, wobei die eine Kunststoffschicht ein Fenster aufweist, durch welches hindurch die freie Stelle des Papierinletts beschriftet werden kann. Allerdings sind keine Vorkehrungen zur Sicherung der Unterschrift gegen Fälschungen getroffen.US Pat. No. 2,545,804 describes an identification card with a paper insert and plastic coating on both sides, the one plastic layer having a window through which the free position of the paper insert can be labeled. However, no precautions have been taken to secure the signature against counterfeiting.

Die oben beschriebenen bekannten Ausweiskarten haben das gemeinsame Merkmal, daß die Unterschrift eigenhändig zu leisten ist. Neben solchen Ausweiskarten gibt es auch Ausweiskarten, bei denen die Unterschrift elektrofotogra­fisch oder mittels Laser aufgebracht wird. Die DE-PS 29 33 436 zeigt eine Ausweiskarte, bei der nicht nur die benutzerbezogenen Informationen (Kartennumemr, Kontonum­mer und dergleichen), sonder auch die Unterschrift elek­trofotografisch auf ein Sicherheits-Papierinlett aufge­bracht wird, welches anschließend beidseitig mit Kunst­stoffolien laminiert wird. Die DE-PS 29 07 004 beschreibt eine Ausweiskarte, bei der sämtliche benutzerbezogenen Informationen einschließlich der Unterschrift durch eine transparente Deckfolie hindurch in das Papierinlett ein­gebrannt werden.The known ID cards described above have the common feature that the signature is to be done by hand. In addition to such identity cards, there are also identity cards in which the signature is applied electrophotographically or using a laser. DE-PS 29 33 436 shows an identification card in which not only the user-related information (card number, account number and the like), but also the signature is applied electrophotographically to a security paper insert, which is then laminated on both sides with plastic films. DE-PS 29 07 004 describes an identification card in which all user-related information, including the signature, is burned through a transparent cover film into the paper inlay.

Aufgabe der Erfindung ist es aber, eine Ausweiskarte zu schafen, die einfach herstellbar ist, auf deren Unter­schriftsfeld nach Fertigstellung der Karte die Unter­schrift sichtbar und in nachträglich nicht mehr veränder­barer, insbesondere austauschbarer Form geschrieben wer­den kann. Außerdem soll ein Verfahren zum Herstellen einer solchen Ausweiskarte angegeben werden.The object of the invention, however, is to provide an identification card that is easy to produce, on the signature field of which the signature can be written after the card has been completed and can be written in a form that can no longer be changed, in particular replaced. In addition, a method for producing such an identity card is to be specified.

Diese Aufgabe wird durch die im Anspruch 1 bzw. die im Anspruch 6 angegebene Erfindung gelöst. Vorteilhafte Wei­terbildungen sind in den Unteransprüchen angegeben.This object is achieved by the invention specified in claim 1 and in claim 6. Advantageous further developments are specified in the subclaims.

Bei der erfindungsgemäßen Ausweiskarte erstreckt sich das ohnehin auf dem Kartenkörper zu Sicherheitszwecken vor­handene Sicherheitsdruckbild bis über das beispielsweise in Siebdrucktechnik aufgebrachte Unterschriftsfeld. Das vorbestimmte Muster des Sicherheitsdruckbildes ist an der Grenze zwischen Unterschriftsfeld und Umgebung des Unter­schriftsfeldes kontinuierlich. Ein Ablösen des Materials des Unterschriftsfeldes und ein Ersetzen des abgelösten Feldes durch ein anderes Feld ist praktisch nicht mög­lich, da das Sicherheitsdruckbild - wenn es den über­haupt nachahmbar sein sollte - mit Sicherheit nicht kon­tinuierlich an das Druckbild im Umgebungsbereich des Un­terschriftsfeldes angepaßt werden kann. Auch die farb­liche Abstimmung des Sicherheitsdruckbildes auf Unter­schriftsfeld und Umgebung läßt eine Fälschung nicht zu. Das Unterschriftsfeld, das bislang eine optische deutlich in Erscheinung tretende Eigenständigkeit besaß, kann bei der erfindungsgemäßen Ausweiskarte mühelos in das Gesamt­erscheinungsbild der Karte einbezogen werden.In the case of the identification card according to the invention, the security print image which is present anyway on the card body for security purposes extends beyond the signature field applied, for example, using screen printing technology. The predetermined pattern of the security print image is continuous at the boundary between the signature field and the surroundings of the signature field. A detachment of the material of the signature field and a replacement of the detached field by another field is practically not possible, since the security print image - if it should be imitable at all - can certainly not be continuously adapted to the print image in the area surrounding the signature field. The color matching of the security print image to the signature field and surroundings also does not allow forgery. The signature field, which so far had a distinct visual appearance, can be effortlessly incorporated into the overall appearance of the card in the ID card according to the invention.

Insbesondere läßt sich das Herstellen des Unterschrifts­feldes gut in den Herstellungsprozeß des Kartenkörpers einbeziehen. Sowohl Sicherheitsdruckbild als auch Unter­schriftsfeld können z. B. im Siebdruckverfahren herge­stellt werden. Um die Karte nach dem Aufbringen des Sicherheitsdruckbildes zu schützen, wird vorzugsweise eine transparente Schutzschicht auf das Sicherheitsdruck­bild aufgebracht, wobei die Schutzschicht ein Fenster freiläßt, durch welches die Unterschrift nachträglich auf das Unterschriftsfeld aufgebracht werden kann.In particular, the production of the signature field can be included in the manufacturing process of the card body. Both the security print image and the signature field can e.g. B. can be produced by screen printing. In order to protect the card after the security print image has been applied, a transparent protective layer is preferably applied to the security print image, the protective layer leaving a window through which the signature can subsequently be applied to the signature field.

Als weitere Maßnahme zur Erhöhung der Fälschungssicher­heit ist vorgesehen, daß das Sicherheitsdruckbild von Karte zu Karte aperiodisch ist. Üblicherweise besitzen Sicherheitsdruckbilder, z. B. Guilloche-Aufdrucke, periodische Muster und erfindungsgemäß ist z. B. dann die Kartenlänge nicht ein ganzzahliges Vielfaches der Muster-Periodizität.As a further measure to increase the security against counterfeiting, it is provided that the security print image is aperiodic from card to card. Usually have security print images, e.g. B. guilloche prints, periodic patterns and the invention is such. B. then the card length is not an integer multiple of the pattern periodicity.

Bei dem erfindungsgemäßen Verfahren wird zunächst das Unterschriftsfeld aufgebracht und erst anschließend das Sicherheitsdruckbild und zwar derart, daß das Druckbild das Unterschriftsfeld zumindest teilweise überlappt. Die besonderen Vorteile des Verfahrens zeigen sich dann, wenn das Unterschriftsfeld z. B. im Siebdruck hergestellt wird und anschließend der Sicherheitsdruck kontinuierlich von der als Kunststoffläche vorliegenden Umgebung aus über das Unterschriftsfeld hinweg aufgebracht wird. Bei beiden Verfahrensschritten handelt es sich um übliche Druckver­fahren, die mit relativ geringem Aufwand durchgeführt werden können. Um ein sehr feines Sicherheitsdruckbild insbesondere im Unterschriftsfeld und im Bereich der Grenze zwischen Unterschriftsfeld und Umgebung zu erhal­ten, kann man zwischen dem Siebdruck- und dem Sicher­heitsdruckvorgang eine Zwischenkaschierung durchführen. Durch diese Zwischenkaschierung wird die Oberfläche des mit dem Unterschriftsfeld versehenen Kartenkörpers ge­glättet, so daß das Sicherheitsdruckbild auf eine homo­gene, bündige Oberfläche aufgebracht werden kann.In the method according to the invention, the signature field is first applied, and only then is the security print image applied, in such a way that the print image at least partially overlaps the signature field. The special advantages of the method show up when the signature field z. B. is produced in screen printing and then the security printing is continuously applied from the environment present as a plastic surface over the signature field. Both process steps are conventional printing processes that can be carried out with relatively little effort. In order to obtain a very fine security print image, especially in the signature field and in the area of the border between the signature field and the surrounding area, intermediate lamination can be carried out between the screen printing and the security printing process. This intermediate lamination smoothes the surface of the card body provided with the signature field, so that the security print image can be applied to a homogeneous, flush surface.

Zum Schutz der Karte wird vorzugsweise eine transparente Deckfolie vorgesehen, wobei der Bereich des Unter­schriftsfeldes ausgespart wird. Statt einer Deckfolie, die immerhin eine Dicke von etwa 80 µm besitzt, kann auch eine wesentlich dünnere Lackschicht aus Kunstharz, z. B. 2-Komponentenharz, UV-härtbarem Harz oder derglei­chen, wiederum unter Aussparung des Unterschriftsfeldes aufgebracht werden. Eine solche Lackschicht hat etwa die gleiche Höhe wie der Siebdruck des Unterschriftsfeldes (etwa 10 µm). Bei der Lackierung des Kartenkörpers mit Kunstharz kann das Fenster drucktechnisch ausgebildet werden. Nach dem Lackieren kann die Karte zur Komplettie­rung nochmals kaschiert werden, damit die Kartenober­fläche vollständig glatt ist.To protect the card, a transparent cover film is preferably provided, the area of the signature field being left out. Instead of a cover film, which at least has a thickness of about 80 microns, a much thinner lacquer layer made of synthetic resin, eg. B. 2-component resin, UV-curable resin or the like, again with the signature field recessed. Such a layer of paint has about same height as the screen printing of the signature field (about 10 µm). When painting the card body with synthetic resin, the window can be designed using printing technology. After painting, the card can be laminated again so that the card surface is completely smooth.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf eine erfindungsgemäße Ausweiskarte,
  • Fig. 2 eine Teil-Querschnittsansischt einer Aus­weiskarte, und
  • Fig. 3 eine Teil-Querschnittsansicht einer wei­teren Ausführungsform einer erfindungsgemä­ßen Ausweiskarte.
Exemplary embodiments of the invention are explained in more detail below with reference to the drawing. Show it:
  • 1 is a plan view of an identification card according to the invention,
  • Fig. 2 is a partial cross-sectional view of an identification card, and
  • Fig. 3 is a partial cross-sectional view of another embodiment of an identification card according to the invention.

Wie aus Fig. 1 hervorgeht, ist etwa in der Mitte eines hier als Vollplastikkarte ausgebildeten Kartenkörpers 1 ein Unterschriftsfeld 2 vorgesehen. Das Unterschrifts­feld ist beispielsweise eine im Siebdruck unter Verwen­dung wegschlagfähiger Druckfarben aufgebracht Druck­schicht, also eine Schicht, die z. B. Kugelschreibertin­ten oder andere in gängigen Schreibgeräten verwendete Tinten bleibend aufnehmen. Andere Druckverfahren für die Aufbringung von Schichtmaterialien mit der Eigenschaft der nachträglichen Beschriftbarkeit sind z. B. das Tief­druckverfahren oder der Tampondruck. Die das Unter­schriftsfeld bildende Schicht kann auch im Transferver­fahren, insbesondere nach dem bekannten Heißprägeverfah­ren, auf die Kartenoberfläche übertragen werden. Ein als Guilloche-Aufdruck ausgebildetes Sicherheitsdruckbild 3, welches in Fig. 1 nur symbolisch angedeutet ist, über­ deckt zumindest einen Teilbereich des Unterschriftsfeldes 2 und zu diesem benachbarte Bereiche der Oberfläche des Kartenkörpers 1. Wie aus Fig. 1 ersichtlich ist, gibt es in dem Muster des Sicherheitsdruckbildes 3 an der Grenze des Unterschriftsfeldes 2 keinerlei Unterbrechungen. Da­durch ist das Unterschriftsfeld praktisch nicht aus­tauschbar oder überdruckbar, ohne daß eine solche Manipu­lation an einer Unregelmäßigkeit im Sicherheitsdruckbild 3 erkennbar wäre.As can be seen from FIG. 1, a signature field 2 is provided approximately in the middle of a card body 1 designed here as a fully plastic card. The signature field is, for example, a printing layer applied in screen printing using impact-resistant printing inks, that is to say a layer which, for. B. ballpoint inks or other inks used in common writing instruments permanently. Other printing methods for the application of layered materials with the property of subsequent writing are z. B. the gravure process or pad printing. The layer forming the signature field can also be transferred to the card surface using the transfer method, in particular according to the known hot stamping method. A security print image 3 in the form of a guilloche print, which is only indicated symbolically in FIG. 1, via covers at least a partial area of the signature field 2 and adjacent areas of the surface of the card body 1. As can be seen from FIG. 1, there are no interruptions in the pattern of the security print image 3 at the border of the signature field 2. As a result, the signature field is practically not interchangeable or overprintable without such manipulation being recognizable by an irregularity in the security print image 3.

Wie aus Fig. 2 hervorgeht, ist der Kartenkörper aus einer dicken Kunststoffschicht gebildet, auf die das Unter­schriftsfeld 2 in einem geeigneten Druckverfahren aufge­bracht ist. Nach dem Aufbringen des Unterschriftsfeldes kann gegebenenfalls die Oberseite der Karte kaschiert werden, um die Oberfläche zu glätten. Dann wird z. B. nach dem gleichen Druckverfahren oder in für Feinlinien­druck geeigneten anderen Druckverfahren das Sicherheits­druckbild 3 aufgebracht. Nach einem nochmaligen Kaschier­schritt wird als transparente glatte Abdeckung eine durchsichtige Kunststoffolie 4 aufgebracht. In dieser Deckfolie 4 ist ein Fenster 5 ausgestanzt, so daß das Unterschriftsfeld 2 für das nachträgliche Einschreiben der Unterschrift des Kartenbenutzers frei bleibt.As can be seen from FIG. 2, the card body is formed from a thick plastic layer, to which the signature field 2 is applied in a suitable printing process. After the signature field has been applied, the top of the card can be laminated to smooth the surface. Then z. B. after the same printing process or in other printing processes suitable for fine line printing, the security print image 3 is applied. After a further lamination step, a transparent plastic film 4 is applied as a transparent, smooth cover. A window 5 is punched out in this cover film 4, so that the signature field 2 remains free for the subsequent registration of the signature of the card user.

Die Größe des Fensters 5 ist in seinen Grenzen frei wähl­bar. Wie in Fig. 1 durch die strichtlierte Begrenzungs­linie 6 angedeutet ist, kann das Kunststoffenster das Unterschriftsfeld 2 etwas überlappen. Es kann jedoch auch ein kleiner umlaufender Spalt zwischen Druckfläche und Kunststoffabdeckung vorgesehen werden, wie in Fig. 2 an­gedeutet ist. Nach dem Aufbringen der Deckfolie 4 kann die Karte nochmals kaschiert werden, um die Oberfläche zu glätten. Als Deckfolie 4 sind dabei möglichst dünne Fo­lien zu wählen, so daß das Unterschriftsfeld nicht durch das dabei erweichende Deckfolienmaterial abgedeckt wird. Foliendicken von ca. 80 µm Dicke erfüllen diese Forde­ rung.The size of the window 5 is freely selectable within its limits. As indicated in FIG. 1 by the dashed boundary line 6, the plastic window can overlap the signature field 2 somewhat. However, a small circumferential gap between the pressure surface and the plastic cover can also be provided, as indicated in FIG. 2. After the cover film 4 has been applied, the card can be laminated again in order to smooth the surface. Foil which is as thin as possible is to be selected as the cover foil 4 so that the signature field is not covered by the cover foil material which softens in the process. Film thicknesses of approx. 80 µm thickness meet this requirement tion.

Statt einer Deckfolie kann eine Kunstharz-Lackschicht vorgesehen werden. Hierzu kann man mit drucktechnischen Mitteln das Fenster 5′ über dem Unterschriftsfeld 2 in einfacher Weise freilassen. In Fig. 3 ist das Sicher­heitsdruckbild 3 durch eine strichpunkierte Linie ange­deutet, der aus transparentem Kunstharz bestehende Lack ist durch eine gestrichelte Linie dargestellt.A synthetic resin lacquer layer can be provided instead of a cover film. For this purpose, you can leave the window 5 'above the signature field 2 in a simple manner with printing technology. In Fig. 3, the security print image 3 is indicated by a dash-dotted line, the paint consisting of transparent synthetic resin is represented by a dashed line.

Die Lackschicht 7 besteht beispielsweise aus UV-härtbarem Harz. Der Kartenkörper 1′ der Ausweiskarte nach Fig. 3 umfaßt zwei Kunststoffschichten. Da die Lackschicht 7 etwa so dick ist wie die Dicke des Unterschriftsfeldes 2 ( 10 µm), erhält man eine praktisch übergangslose, glatte Kartenoberfläche, deren Glattheit durch einen ab­schließenden Kaschierschritt sogar noch verbessert werden kann.The lacquer layer 7 consists, for example, of UV-curable resin. The card body 1 'of the identification card according to Fig. 3 comprises two plastic layers. Since the lacquer layer 7 is approximately as thick as the thickness of the signature field 2 (10 μm), a practically seamless, smooth card surface is obtained, the smoothness of which can even be improved by a final laminating step.
