Definitions

• 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.
• UV 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.
• 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.
• the single figure shows the flow diagram for a method for producing printed smart cards, which is described by steps 1-6 below:
• KS substrate plastic substrate
• This generally consists of a film material, which is usually available in roll form.
• 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 ⁇ m, typically 50 - 100 ⁇ m.
• ABS acrylonitrile / butadiene / styrene
• PC polycarbonate
• PVC polyvinyl chloride
• PP polypropylene
• PE polyethylene
• PS polystyrene
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• Example 1 describes the production of a smart card based on an 80 ⁇ m thick ABS film.
• Roll material of an 80 ⁇ m thick acrylonitrile / butadiene / styrene film (Kunststofftechnik 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).
• a chip (Siemens) was inserted into it. This was a smart card printed on both sides.
• Example 2 describes the production of a smart card starting from a 100 ⁇ m thick polycarbonate film.
• Roll material of a 100 ⁇ m thick polycarbonate film (General Electric, USA) with a width of 1.5 m was cut into sheets of 50 x 35 cm. These sheets were printed with UV inks (Amra, Lachen, CH) using an offset printing machine (Miller TP74) with UV offset printing plates at 3,000 prints / h in 2 steps. After the first two printing inks, there was an intermediate drying with UV lamps of 2 x 70 W / cm 2 , while the final drying was carried out after printing with the remaining inks 3 x 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 printed product (label) assembled in this way was now individually brought to the inside of an injection mold.
• the injection molding was carried out at 160 ° C with hard PVC (polyvinyl chloride). After removing the product from the tool it was put into this a chip (Philips) inserted. This was a smart card printed on one side.
• Example 3 describes the production of a smart card based on an 80 ⁇ m thick polystyrene film. Sheet material with the dimensions 70 x 100 cm of an 80 ⁇ m thick polystyrene film
• 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).
