Description

Verfahren zur Herstellung von bedruckten Smart Cards Process for the production of printed smart cards
Die vorliegende Erfindung betrifft ein Verfahren zur Herstel¬ lung von bedruckten Smart Cards gemäss dem Wortlaut des Patent¬ anspruchs 1. Unter dem Begriff Smart Card wird eine Kreditkarte verstanden, welche besonders günstig hergestellt werden kann und demzufolge auch einen WegwerfCharakter hat.The present invention relates to a method for producing printed smart cards in accordance with the wording of patent claim 1. The term smart card is understood to mean a credit card which can be produced particularly cheaply and consequently also has a disposable character.
Bisher wurden zum Bedrucken von Kunststoffen verschiedene Druckverfahren eingesetzt, wie etwa der Siebdruck, der Flexo- druck, der Tampon- und der Tiefdruck. Diese Verfahren wurden vor allem wegen ihrer guten Trocknungseigenschaften verwendet. Insbe¬ sondere werden bei Sieb-, Flexo- und Tiefdruck sehr leichtflüch¬ tige Lösungsmittel verwendet, wie Benzolderivate, oder ähnliche dieser Art. Hieraus ergibt sich ein Nachteil dieser Verfahren, da diese Lösungsmittel nicht unbedenklich eingesetzt werden können und zur Einhaltung der maximal zulässigen Arbeitplatzkon¬ zentrationen (MAK-Werte) meist aufwendige AbluftSysteme, bzw. Ventilationsanlagen eingesetzt werden müssen.So far, various printing processes have been used to print plastics, such as screen printing, flexographic printing, tampon printing and gravure printing. These processes were mainly used because of their good drying properties. In particular, very volatile solvents, such as benzene derivatives, or the like, are used in screen, flexographic and gravure printing. This results in a disadvantage of these processes, since these solvents cannot be used safely and to maintain the maximum permissible workplace ¬ concentrations (MAK values) mostly complex exhaust air systems or ventilation systems must be used.
Im weiteren sind Offsetdruckverfahren bekannt, welche heute weltweit zu den meistverbreiteten Verfahren zählen und zufolge von Druckqualität und der Leistungsfähigkeit des Verfahrens für den Druck von Prospekten, Akzidenzen und Verpackungen eine breite Verwendung finden. Das Ultraviolett-Offsetverfahren, oder UV- Offsetverfahren verwendet UV-Druckfarben, welche einen Fotoini¬ tiator enthalten und nach dem Auftragen mittels UV zum Vernetzen gebracht werden. Dadurch kann auf ein Lösungsmittel verzichtet werden. Dieses Verfahren eignet sich vorwiegend zum Bedrucken von Oberflächen, die aus nichtsaugenden Materialien bestehen, insbe¬ sondere aus Kunststoffen.In addition, offset printing processes are known, which are among the most widespread processes worldwide and are widely used due to the print quality and the efficiency of the process for printing brochures, commercial documents and packaging. The ultraviolet offset process, or UV offset process, uses UV printing inks which contain a photo initiator and are crosslinked after application by means of UV. This eliminates the need for a solvent. This method is primarily suitable for printing on surfaces which consist of non-absorbent materials, in particular plastics.
Die Aufgabe der Erfindung ist es, ein Verfahren zur Herstel¬ lung von bedruckten Smart Cards vorzuschlagen, welches mittels eines UV-Prozesses ein rohes Druckerzeugnis liefert, wobei dieses konfektioniert wird und in ein Form eingebracht zu einer bedruck¬ ten Smart Card weiterverarbeitet wird.The object of the invention is to propose a method for the production of printed smart cards, which means of a UV process provides a raw printed product, which is then assembled and processed into a mold and processed into a printed smart card.
Erfindungsge äss wird diese Aufgabe mit einem Verfahren gemäss dem Wortlaut des Patentanspruchs 1 gelöst. Ausführungsar¬ ten sind in den Patentansprüchen 2 bis 4 umschrieben. Patentan¬ spruch 5 zeigt eine bevorzugte Anwendung. Das erfindungsgemässe Verfahren wird unter Bezug auf das Flussdiagramm (einzige Figur) näher erläutert, wobei in der einzigen Figur die allgemeinen Schritte dargestellt sind. Dabei werden für die Beschreibung der verschiedenen Verfahrensschritte diejenigen Referenzzahlen des Flussdiagrammes verwendet, die für die Gliederung der einzelnen Schritte angeführt sind. In den Beispielen 1 - 3 werden Ausfüh¬ rungsbeispiele dazu beschrieben.This task is solved according to the invention with a method according to the wording of claim 1. Embodiments are described in claims 2 to 4. Patent claim 5 shows a preferred application. The method according to the invention is explained in more detail with reference to the flow diagram (single figure), the general steps being shown in the single figure. For the description of the different process steps, those reference numbers of the flow chart are used which are given for the structure of the individual steps. Examples 1-3 are described for this purpose.
Die einzige Figur zeigt das Flussdiagramm für ein Verfahren zur Herstellung von bedruckten Smart Cards, welches durch die Schritte 1 - 6 nachstehend beschrieben wird:The single figure shows the flow diagram for a method for producing printed smart cards, which is described by steps 1-6 below:
1. Bedrucken mit UV-Farben1. Printing with UV inks
Ausgangspunkt des Verfahrens ist ein Kunststoff-Substrat (KS- Substrat) . Dieses besteht im allgemeinen aus einem Folienmate¬ rial, welches meistens in Rollenform verfügbar ist. Als Kunst¬ stoffe kommen etwa Acrylnitril/Butadien/Styrol (ABS) , Polycarbo- nat (PC) , Polyvinylchlorid (PVC) , Polypropylen (PP) , Polyethylen (PE) , Polystyrol (PS) und andere mehr in Frage, in Dicken von 20 - 150 μm, typischerweise 50 - 100 μm. Das Rollenmaterial wird in Bogen zerschnitten und so in Stapeln einer Offsetdruckmaschine zugeführt. Als Druckfarben werden sogenannte Ultraviolett-Druck- farben für Nass- und Trockenoffset verwendet.The starting point of the process is a plastic substrate (KS substrate). This generally consists of a film material, which is usually available in roll form. Examples of suitable plastics are acrylonitrile / butadiene / styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene (PS) and others, in thicknesses of 20 - 150 μm, typically 50 - 100 μm. The roll material is cut into sheets and fed to an offset printing machine in stacks. So-called ultraviolet printing inks for wet and dry offset are used as printing inks.
2. Trocknen2. Drying
Nach dem Druckvorgang wird der bedruckte Bogen oder das bedruckte Folienmaterial in bekannterweise getrocknet, was etwa mittels einer Anordnung von UV-Strahlern erfolgt. Nach der Trocknung liegt ein bedrucktes rohes Druckerzeugnis vor. 3. VerarbeitenAfter the printing process, the printed sheet or the printed film material is dried in a known manner, which is done, for example, by means of an arrangement of UV lamps. After drying, a printed raw printed product is available. 3. Process
Das rohe Druckerzeugnis, welches beispielsweise als Bogen mit Mehrfachnutzen vorliegt, wird nun gestanzt, oder geschnitten, wodurch das gewünschte Format des Endproduktes erreicht wird. So kann beispielsweise das Stanzwerkzeug so gewählt werden, dass es bereits die endgültige Format einer Kreditkarte vorweist, einschliesslich der an diese geforderten Toleranzen entsprechend den Standards ISO 7810 und ISO 7816. Nach diesem Verarbeitungs¬ schritt liegt ein konfektioniertes Druckerzeugnis, auch Label genannt, im Endformat vor.The raw printed product, which is available, for example, as a sheet with multiple uses, is now punched or cut, whereby the desired format of the end product is achieved. For example, the punching tool can be selected so that it already shows the final format of a credit card, including the tolerances required for it in accordance with the ISO 7810 and ISO 7816 standards in front.
4. Beschicken der Form4. Feed the mold
Mit dem konfektionierten Druckerzeugnis wird nun eine Form aus¬ gelegt, welche beispielsweise eine Spritzgussform sein kann, und dies kann in einfacher oder zweifacher Art erfolgen, abhängig davon, ob eine einseitig oder beidseitig bedruckte Smart Card erzeugt werden soll.The finished printed product is then used to lay out a mold, which can be, for example, an injection mold, and this can be done in a simple or double manner, depending on whether a smart card printed on one or both sides is to be produced.
5. Spritzen, Blasen, Tiefziehen5. Injection, blowing, deep drawing
In einem Spritzguss-, Blas- oder Tiefziehverfahren wird nun ein zweiter Kunststoff derart appliziert, dass an das eingelegte Druckerzeugnis, bzw. an die eingelegten Druckerzeugnisse, ein zweiter Kunststoff gespritzt, geblasen oder tiefgezogen wird. Dadurch bildet das rohe Druckerzeugnis mit dem applizierten, zweiten Kunststoff einen Verbund. Die Wahl dieses zweiten Kunststoffes erfolgt aufgrund des in Schritt 1 verwendeten KS- Substrates. Er sollte vorteilhafterweise der gleichen Kunststoff¬ gruppe angehören und ist im Idealfall mit dem KS-Substrat identisch. Bedingung für eine Eignung ist die Verarbeitbarkeit, d.h. die Labels müssen auf der Smart Card eine hinreichend gute Haftung aufweisen. Überraschenderweise hat sich gezeigt, dass auf diese Art ein hochfestes Verbundmaterial erhalten wird, welches sämtliche Anforderungen an eine Smart Card in hohem Masse erfüllt, wie etwa Bruchfestigkeit, Elastizität, Formstabilität. Qualitativ erwiesen sich diese Smart Cards den bisherigen Kredit¬ karten als ebenbürtig, jedoch bezüglich der Geschwindigkeit ihrer Herstellung und der Kostenstruktur sind sie jenen deutlich über¬ legen. Nach dem Entfernen des Produktes aus der Form liegt eine bedruckte Smart Card vor, in welcher im allgemeinen ein Fenster für den Chip vorgesehen ist.A second plastic is then applied in an injection molding, blowing or deep-drawing process in such a way that a second plastic is injected, blown or deep-drawn onto the inserted printed product or onto the inserted printed products. As a result, the raw printed product forms a composite with the applied second plastic. This second plastic is selected on the basis of the KS substrate used in step 1. It should advantageously belong to the same plastic group and is ideally identical to the KS substrate. Processability is a prerequisite for suitability, ie the labels must have sufficient adhesion on the smart card. Surprisingly, it has been shown that a high-strength composite material is obtained in this way, which fulfills all requirements for a smart card to a high degree, such as breaking strength, elasticity, dimensional stability. In terms of quality, these smart cards proved to be on a par with the previous credit cards, but they are clearly superior to those in terms of the speed of their production and the cost structure. After the product has been removed from the mold, there is a printed smart card in which a window is generally provided for the chip.
6. Einfügen des Chips6. Insert the chip
In das erwähnte Fenster wird der Chip eingefügt, was in bekann¬ terweise durch Einkleben, Einschmelzen oder Versiegeln erfolgen kann, was hier nicht näher beschrieben wird. Selbstverständlich kann statt eines Chip auch ein Magnetband, bzw. ein Magnetstrei¬ fen eingefügt werden, oder ein programmierbarer Informationsträ¬ ger irgendwelcher Art. Somit steht nun eine fertige bedruckte Smart Card zur Verfügung, die nur noch programmiert werden muss.The chip is inserted into the window mentioned, which can be done in known manner by gluing, melting or sealing, which is not described in more detail here. Of course, instead of a chip, a magnetic tape or a magnetic strip or a programmable information carrier of any kind can also be inserted. A finished printed smart card is now available which only needs to be programmed.
Das hier mit den Schritten 1 - 6 beschriebene Verfahren er¬ möglicht die Einsparung wesentlicher Arbeitsgänge, da kein Kartenrohling mehr vorliegen muss, welcher in einem zweiten Schritt mit Etiketten versehen oder bedruckt werden muss. Das vorgestellte Verfahren stellt gewissermassen ein Umkehrverfahren dar, indem der Druckvorgang vorangestellt wird und die volumi¬ nösen Karten jeweils On demand' , d.h. auf Anfrage in einem Spritz-, Blas- oder Tiefziehverfahren hergestellt werden. Ein weiterer Vorteil besteht in der Tatsache, dass für eine beidsei- tig bedruckte Smart Card, diese in einem Schritt 'an die Labels' gespritzt werden kann. In bisher bekannten Verfahren wurden hier¬ für ausgehend von einem Kartenrohling, ein erster Druckvorgang für die Vorderseite, und anschliessend ein zweiter Druckvorgang für die Rückseite notwendig, was bekannterweise ein umständliches Handling erfordert, und beim erfindungsgemässen Verfahren ent¬ fällt.The method described here with steps 1-6 makes it possible to save essential work steps, since there is no longer any need for a blank card which must be provided with labels or printed in a second step. To some extent, the method presented represents a reversal method in that the printing process is preceded and the voluminous cards are each on demand, i.e. can be produced on request in a spray, blow or deep-drawing process. Another advantage is the fact that for a smart card printed on both sides, it can be injected 'onto the labels' in one step. In previously known processes, starting from a blank card, a first printing process for the front and then a second printing process for the back were necessary, which is known to require laborious handling, and is eliminated in the process according to the invention.
Das Verfahren hat im weiteren den besonderen Vorteil, dass die auf diese Weise erzeugten Smart Cards bei Verwendung gleich¬ artiger Kunststoffe für KS-Substrat und zweiten Kunststoff re- zyklierfähig sind, da sie aus einem monomeren Verbund bestehen.The method also has the particular advantage that the smart cards produced in this way are used when using the same type of plastic for the KS substrate and the second plastic. are cyclable because they consist of a monomeric composite.
Beispiel 1 beschreibt die Herstellung einer Smart Card aus¬ gehend von einer 80 μm dicken ABS-Folie. Rollenmaterial einer 80 μm dicken Acrylnitril/Butadien/Styrol-Folie (Kunststoffwerk Staufen (KWS) , Deutschland) von 1 Breite wurde zu Bogen von 50 x 35 cm zugeschnitten. Diese Bogen wurden mit UV-Farben (SICPA, Lausanne, CH) mittels einer Offsetdruckmaschine (Miller TP74) mit UV-Offsetdruckplatten bei 4'500 Drucken/h bedruckt. Danach wurden die bedruckten Bogen mit UV-Lampen von 3 x 120 W/cm2 getrocknet. Mit einem erodierten Stanzwerkzeug auf einer Stanzmaschine Busch wurden die Label ausgestanzt, wonach sie in ihrem Endformat vorlagen. Die konfektionierten Druckerzeugnisse wurden nun paarweise an die Innenseite eines Spritzwerkzeugs gebracht. Das Spritzgiessen erfolgte bei 280°C mit ABS (KWS, Deutschland) . Nach dem Entfernen des Produktes aus dem Werkzeug wurde in dieses ein Chip (Siemens) eingefügt. Damit lag eine beidseitig bedruckte Smart Card vor.Example 1 describes the production of a smart card based on an 80 μm thick ABS film. Roll material of an 80 μm thick acrylonitrile / butadiene / styrene film (Kunststoffwerk Staufen (KWS), Germany) of 1 width was cut into sheets of 50 x 35 cm. These sheets were printed with UV inks (SICPA, Lausanne, CH) using an offset printing machine (Miller TP74) with UV offset printing plates at 4,500 prints / h. The printed sheets were then dried with UV lamps of 3 × 120 W / cm 2 . The labels were punched out using an eroded punching tool on a Busch punching machine, after which they were available in their final format. The assembled printed products were now brought in pairs to the inside of an injection mold. The injection molding was carried out at 280 ° C with ABS (KWS, Germany). After removing the product from the tool, a chip (Siemens) was inserted into it. This was a smart card printed on both sides.

Diese Bogen wurden mit UV-Farben (Amra, Lachen, CH) mittels einer Offsetdruckmaschine (Miller TP74) mit UV-Offset¬ druckplatten bei 3'000 Drucken/h in 2 Schritten bedruckt. Nach den ersten beiden Druckfarben erfolgte eine Zwischentrocknung mit UV-Lampen von 2 x 70 W/cm2, während die Endtrocknung nach Bedrucken mit den restlichen Farben 3 x 120 W/cm2 erfolgte. Mit einem erodierten Stanzwerkzeug auf einer Stanzmaschine Busch wurden die Label ausgestanzt, wonach sie in ihrem Endformat vorlagen. Das so konfektionierte Druckerzeugnis (Label) wurde nun einzeln an die Innenseite eines Spritzwerkzeugs gebracht. Das Spritzgiessen erfolgte bei 160°C mit Hart-PVC (Polyvinylchlorid) . Nach dem Entfernen des Produktes aus dem Werkzeug wurde in dieses ein Chip (Philips) eingefügt. Damit lag eine einseitig bedruckte Smart Card vor.Example 2 describes the production of a smart card starting from a 100 μm thick polycarbonate film.

Danach wird ein Chip eingefügt, wodurch eine mindestens einseitig bedruckte Smart Card erzeugt wird, ohne dass ein Rohling im üblichen Sinne notwendig ist. Dieses interessante Verfahren ist ein Herstellungsverfahren für Smart Cards im IML- Verfahren (In Mould Labelling) . It is essential to the invention that a plastic substrate is printed with lab printing using UV printing inks in UV offset printing and dried. The labels are put together in a form in which they are processed with a second plastic into a composite material. Then a chip is inserted, whereby a smart card printed on at least one side is produced without a blank being necessary in the usual sense. This interesting process is a manufacturing process for smart cards using the IML process (In Mold Labeling).
