Description

The present invention relates to an ID card manufacturing method, an ID card sheet, an ID card set, and a card position determination method.

ID cards such as identification cards have a photograph of a person's face and text information such as the person's address and name written on the surface of the card so that the person can be individually recognized. In addition, personal information may be recorded in the memory of an electronic component provided inside the card.

Various measures have been taken for such ID cards so that it can be easily determined whether or not they have been forged or altered. For example, characters are printed on the surface of cards using holograms or special ink whose optical properties change, or micro characters are printed that can only be seen with a magnifying glass. Also, a pattern is provided inside the card by watermark printing so that the owner does not recognize that the pattern is printed on the card. For example, cards have been proposed in which the card user does not recognize the watermark pattern during normal use, but can only discern the pattern inside the card in certain cases, for example when the card is viewed through sunlight or indoor lighting. (See Patent Documents 1 and 2).

Conventionally, cards with patterns printed on them have been manufactured by punching out large sheets into card units from the viewpoint of productivity. The watermark pattern was printed on the entire sheet, and each of the cards punched out from the sheet had a common (identical) watermark pattern printed on it.

If you want to know the manufacturing history of an ID card, you will need location information that shows which part of the sheet it was punched from, but with ID cards manufactured using conventional methods, it is not possible to identify the punching position. could not.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In addition, in the drawings attached to this specification, for convenience of illustration and ease of understanding, the scale and the vertical and horizontal dimensional ratios are appropriately changed and exaggerated from those of the actual drawings.

FIG. 1 is a schematic front view of an ID card according to an embodiment of the present invention viewed from the information recording layer side, and FIG. 2 is a sectional view taken along line II-II in FIG. 1. The ID card 10 includes a card core layer 1 containing an electronic component 7, a front base material layer 2 provided on one side of the card core layer 1, and an information recording layer provided on the surface of the front base material layer 2. It has layer 3. The information recording layer 3 is printed with image information 5a and character information 5b that are recorded when the ID card is issued, in addition to format printing that is preformed when the ID card is manufactured. The electronic component 7 is an integrated circuit (IC), and the ID card 10 is also called an IC card.

An information recording layer 3 is provided on one side of the front base material layer 2, and a pattern 4 is printed on the other side. The pattern 4 is, for example, a pattern in which patterns (pattern elements) such as letters and marks are repeated at predetermined intervals. In addition, this pattern 4 cannot be recognized when the surface of the ID card is viewed under normal brightness, but when the ID card is held up to sunlight or indoor lighting, etc., the pattern cannot be recognized. It may also be a so-called watermark pattern whose shape can be recognized. A watermark pattern allows users to recognize the shape of the pattern printed on the inside of an ID card by utilizing the fact that the amount of light that passes through the ID card differs between the patterned part and the non-patterned part. . Therefore, although the light transmittance in the thickness direction of the ID card must not be 0%, as long as it has a certain degree of transmittance, the watermark pattern can be recognized.

FIG. 3 is a view of the ID card viewed from the information recording layer 3 (protective layer 6) side with light irradiated from the back base layer 8 (writing layer 9) side. When looking through the ID card, as shown in FIG. 3, not only the character information and image information printed on the information recording layer but also the IC chip 7a, antenna 7b, and pattern 4 housed inside the card can be seen. be able to.

First, pattern 4 will be explained. An ID card is manufactured by sandwiching an inlet containing an electronic component 7 between a front base material layer 2 provided with an information recording layer 3 and a back base material layer 8, and laminating them together with an adhesive. The pattern 4 is formed by printing a predetermined pattern on one side of the front base material layer 2 before laminating the front base material layer 2 and the back base material layer 8. From the viewpoint of productivity, a pattern is printed on a large sheet, and a plurality of ID cards are punched out card by card from the sheet to produce an ID card set consisting of a plurality of ID cards.

In consideration of the disposal of the sheet after ID card punching, the pattern is not printed on the entire surface of the sheet, but is printed in a matrix, for example, in a size slightly larger than the size of the ID card. That is, pattern printing areas of a size slightly larger than the ID card size or smaller are arranged in a matrix on the sheet. One ID card is punched out from one pattern printing area. Personal information such as a face image and address may be printed on the information recording layer 3 after punching out each ID card. Further, a print pattern common to each ID card may be format-printed at the sheet stage.

FIG. 4 shows how a sheet 11 with a pattern 4 printed on the back side of the front base layer 2 is irradiated with light from the back side (pattern side) of the front base layer 2 when viewed from the information recording layer 3 side. It is a diagram. In FIG. 4, pattern printing areas 12a to 12i are provided in 3 columns x 3 rows for ease of understanding, but from the viewpoint of productivity etc., about 50 pattern printing areas are printed on one sheet. Preferably, a pattern printing area is included.

In the example shown in FIG. 4, the pattern printing areas 12a to 12i are rectangular (including a substantially rectangular shape) slightly larger than the size of the ID card 10. In the example shown in FIG. Further, in this example, the pattern printing areas 12a to 12i have the same size, and the intervals between the pattern printing areas are constant. That is, in the sheet 11, the vertical positions of the pattern printing areas 12a, 12d, and 12g are the same. Similarly, in the sheet 11, the vertical positions of the pattern printing areas 12b, 12e, and 12h are the same. In the sheet 11, the vertical positions of the pattern printing areas 12c, 12f, and 12i are the same. Moreover, in the sheet 11, the horizontal positions of the pattern printing areas 12a, 12b, and 12c are the same. Similarly, in the sheet 11, the horizontal positions of the pattern printing areas 12d, 12e, and 12f are the same. In the sheet 11, the horizontal positions of the pattern printing areas 12g, 12h, and 12i are the same.

As shown in FIG. 4, the same pattern 4 is printed in nine pattern printing areas 12a to 12i. In this embodiment, as shown in FIG. 5, the punching position (solid line rectangle in the figure) of the ID card is changed for each pattern printing area 12a to 12i. In the example shown in FIG. 5, the ID card is punched out in the upper left part of the pattern printing area 12a in the figure. In the pattern printing area 12c, an ID card is punched out at the lower left portion in the figure. In the pattern printing area 12e, an ID card is punched out at the center. In the pattern printing area 12i, an ID card is punched out at the lower right portion in the figure. As a result, the patterns 4 of the nine ID cards 10 punched from the pattern printing areas 12a to 12i have the same pattern, but the pattern positions (pattern element positions) are slightly different.

FIG. 6 shows an example of the pattern 4 of the ID card 10 punched out from the pattern printing areas 12a and 12b. For example, in the ID card 10 punched from the pattern printing area 12a, the pattern (pattern element) starts from the upper left corner of the card. In the ID card 10 punched from the pattern printing area 12b, the pattern is interrupted at the upper edge of the card. Information on the pattern of each ID card 10 punched out from the pattern printing areas 12a to 12i is recorded in association with the position of the pattern printing area. For example, data associating pattern information with the position of a pattern printing area is recorded in a storage unit (not shown) of a computer.

By providing such a pattern inside the ID card, it is possible to determine from which pattern printing area of the sheet 11 the ID card 10 is punched from the pattern position (pattern element position) of the pattern. You can easily check the manufacturing history.

The size of the pattern printing area is about 100% or more and 111% or less in both the vertical and horizontal directions compared to the size of the ID card 10. This makes it easier to produce a plurality of ID cards 10 with different pattern positions and with patterns printed on the entire surface (almost the entire surface) of the card by shifting the card punching positions. Moreover, the pattern remaining area on the sheet 11 after card punching becomes smaller, and the cost of disposing of the used sheet 11 can be reduced. The size of the pattern printing area described above is the size when the pattern is printed on the entire surface of the card, and this does not apply when the pattern is printed not on the entire surface of the card but only on a part of the card.

In order to prevent the pattern (pattern element) from being recognized from the pattern remaining area on the used sheet 11, the width of the pattern remaining area is set to be 30% or less of the pattern size (pattern element size). It is preferable to do so.

In the above embodiment, as shown in FIG. 5, an example was explained in which the card punching area is shifted vertically and horizontally in the pattern printing areas 12a to 12i, but as shown in FIG. 7, the rotation angle (tilt) of the card punching area is changed. The pattern may be changed for each ID card.

In the example shown in FIG. 5, the vertical positions of the card punching areas in the horizontally aligned pattern printing areas are aligned, and the horizontal positions of the card punching areas in the vertically aligned pattern printing areas are aligned. For example, the vertical positions of the card punching areas in the pattern printing areas 12a, 12d, and 12g are the same. Furthermore, the horizontal positions of the card punching areas in the pattern printing areas 12a, 12b, and 12c are the same. However, as shown in FIG. 8, the vertical and horizontal positions of the card punching areas do not have to match in adjacent pattern printing areas. That is, in the sheet 11, the card punching areas may be arranged at irregular intervals in the vertical and horizontal directions.

Further, as shown in FIG. 9, the card punching areas are arranged at regular intervals (equal intervals) on the sheet 11, and the pattern printing areas 12a to 12i are arranged at irregular intervals, so that the pattern changes for each ID card. You can do it like this. By arranging the pattern printing areas 12a to 12i at irregular intervals, the vertical and horizontal positions of adjacent pattern printing areas do not match. Manufacturing is easy because it is sufficient to punch out the sheets 11 at equal intervals.

As shown in FIG. 10, the pattern patterns of the pattern printing areas 12a to 12i may be different from each other. In this case, it is necessary to prepare the same number of patterns as the number of ID cards to be punched out from the sheet 11.

Hereinafter, the configuration of each layer of the ID card according to the embodiment of the present invention will be described with reference to FIG. 2. The front base material layer 2 is a layer that supports the information recording layer on which image information 5a and the like are printed, and also supports the card core layer 1 provided between it and the back base material layer 8. A pattern 4 is printed on the surface of the front base material layer 2 that is opposite to the surface on which the information recording layer 3 is provided.

As the front base material layer 2 and the back base material layer 8, materials used as materials for various card base materials can be used, such as polyethylene terephthalate, polybutylene terephthalate, polyethylene terephthalate-isophthalate copolymer. Polyesters such as polyethylene, polypropylene, polyolefins such as polymethylpentene, polyfluorinated ethylene resins such as polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, nylon 6, nylon Polyamides such as 6.6, polyvinyl chloride, vinyl chloride-vinyl acetate copolymers, ethylene-vinyl acetate copolymers, ethylene-vinyl alcohol copolymers, polyvinyl alcohol, vinyl polymers such as vinylon, biodegradable fats Biodegradable resins such as group polyester, biodegradable polycarbonate, biodegradable polylactic acid, biodegradable polyvinyl alcohol, biodegradable cellulose acetate, biodegradable polycaprolactone, cellulose resin such as cellulose triacetate, cellophane, polymethane Examples include acrylic resins such as methyl acrylate, polyethyl methacrylate, polyethyl acrylate, and polybutyl acrylate; and synthetic resin sheets such as polystyrene, polycarbonate, polyarylate, and polyimide; among these, polyethylene terephthalate is preferred. It can be used for.

The thickness of the front base material layer 2 and the back base material layer 8 is 30 μm or more and 300 μm or less, preferably 50 μm or more and 200 μm or less. By setting the thickness to 50 μm or more, it is possible to effectively suppress thermal shrinkage when heated when the front base material layer and the back base material layer are bonded to each other via an adhesive. Note that the sheet member may be subjected to an annealing treatment to reduce the thermal shrinkage rate.

The pattern 4 is formed on the surface of the above-mentioned front base material layer 2 opposite to the surface on which the information recording layer 3 is provided. When the pattern 4 is a watermark pattern, it is sufficient that it is printed with an ink having low light transmittance, and it can be formed using a commonly used opaque ink. Since the light transmittance of the part with the pattern (pattern element) is lower than that of the part where the pattern (pattern element) is not printed, light is transmitted from the back base material layer 8 (writing layer 9) side of the ID card 10. When irradiated with light and viewed from the front base material layer 3 (protective layer 6) side, or when irradiated with light from the front base material layer side 3 (protective layer 6) and viewed from the back base material layer 8 (writing layer 9) side. Then, it can be recognized as a "watermark pattern."

The information recording layer 3 is a layer in which image information 5a such as a face photograph and character information 5b such as the card type, name, address, date of birth, expiration date, etc. are recorded. Furthermore, in addition to the above-described image information 5a and character information 5b, the information recording layer 3 may have format printing (not shown) such as a frame of the image information 5a and fixed characters other than the character information 5b. Further, the ID card may be provided with a protective layer 5 on the information recording layer 3 in order to protect the image and character information recorded on the information recording layer 3 described above.

The image information 5a and the character information 5b are printed on the information recording layer 3 by transferring sublimation dye or heat-melting ink using a thermal transfer recording method. Therefore, the information recording layer 3 is preferably formed from a material to which a heat-transferable coloring material such as a sublimable dye or a heat-melting ink is easily transferred. Conventionally known resin materials can be used as such materials, such as polyolefins such as polypropylene, halogenated resins such as polyvinyl chloride or polyvinylidene chloride, polyvinyl acetate, and vinyl chloride-vinyl acetate copolymers. , vinyl resins such as ethylene-vinyl acetate copolymers or polyacrylic esters, polyesters such as polyethylene terephthalate or polybutylene terephthalate, polystyrene, polyamides, copolymers of olefins such as ethylene or propylene with other vinyl polymers, ionomers or cellulose resin such as cellulose diastase, polycarbonate, etc., and vinyl chloride, acrylic-styrene, or polyester are particularly preferred.

Format printing may be performed on the information recording layer 3 using commonly used Bk ink or the like.

The information recording layer 3 can be formed by preparing a coating liquid in which each of the above-mentioned components is dispersed or dissolved in a solvent, applying the coating liquid to one side of the front base material layer 2 to be described later, and drying the coating liquid. The thickness of the information recording layer 3 is generally about 1 μm or more and 50 μm or less, preferably about 2 μm or more and 10 μm or less.

The protective layer 6 has the function of protecting the information recording layer and improving the durability of the ID card, and after printing the image information 5a etc. on the information recording layer 3 described above, using a protective layer transfer sheet, It is formed by transferring the protective layer 6 onto the information recording layer 3. As the protective layer, in order to protect the information recording layer, any conventionally known resin can be used as long as it has excellent durability and transparency, such as acrylic resin, cellulose, polyvinyl acetal, polyester, and polyamide. , epoxy resin, etc.

Card core layer 1 is a layer for accommodating electronic components 7. The electronic component 7 is composed of an IC chip 7a and a coiled antenna 7b, but an adhesive is applied to the above-mentioned front base material layer 2 and back base material layer 8, and the adhesive for the front base material layer is applied. The card core layer 1 is formed by placing the electronic component 7 on the surface and sandwiching it between the back base material layers 8. In order to maintain the smoothness of the ID card, instead of directly sandwiching the electronic component 7 between the front base material layer and the back base material layer via an adhesive, an inlet (not shown) may be sandwiched between the front base material layer and the back base material layer. In order to encapsulate electronic components in the adhesive applied to the base material, the inlet is used to encapsulate electronic components in a porous resin film, porous foamed resin film, flexible resin sheet, or porous resin. It is made into a sheet or non-woven sheet. The total thickness of the electronic component including the inlet is preferably 100 μm or more and 600 μm or less, more preferably 150 μm or more and 500 μm or less, particularly preferably 150 μm or more and 450 μm or less.

Methods for forming a laminated structure in which a card core layer containing electronic components 7 is provided between the front base material layer 2 and the back base material layer 8 include a thermal lamination method, an adhesive lamination method, and an adhesive coating method. and injection molding methods, but each member may be bonded together by any method. When using an adhesive for bonding, conventionally known adhesives can be used without particular limitations, but in the present invention, hot melt adhesives etc. can be suitably used. For example, ethylene - Examples include vinyl acetate copolymer (EVA) adhesives, polyester adhesives, polyamide adhesives, thermoplastic elastomer adhesives, and polyolefin adhesives. Among these, moisture-curing adhesives are preferred. The thickness of the card core layer is preferably 100 μm or more and 600 μm or less, more preferably 150 μm or more and 500 μm or less, particularly preferably 150 μm or more and 450 μm or less.

Further, a writing layer 9 may be provided on the surface of the back base material layer 8. The writing layer is a layer on which writing can be written on the back side of the ID card. As the writing layer, for example, a thermoplastic resin (polyolefin such as polyethylene, various copolymers, etc.) film containing inorganic fine powder such as calcium carbonate, talc, diatomaceous earth, titanium oxide, barium sulfate, etc. is used as the backing layer. It can be formed by providing it on the surface of a layer.

The pattern 4 may be formed on the other surface side of the front base material layer 2, for example, on the surface of the above-described back base material layer 8 on which the card core layer 1 is provided.

One sheet 11 has a first pattern printing area in which a pattern 4 is formed on the surface of the front substrate layer 2 opposite to the surface on which the information recording layer 3 is provided, and a back substrate layer 8. A second pattern printing area in which the pattern 4 is formed may be provided on the surface on which the card core layer 1 is provided. For example, the odd numbered columns are the first pattern printing area, and the even numbered columns are the second pattern printing area.

In the above embodiment, an example in which a pattern is printed on the entire surface of the card has been described, but the pattern may be printed only on a portion of the card. For example, as shown in FIG. 11, frame-shaped pattern printing areas 12m to 12u may be provided on the sheet 11. In the pattern printing areas 12m to 12u, the inner frame is smaller than the card size, and the outer frame is larger than the card size. ID cards punched out from the pattern printing areas 12m to 12u have the pattern printed only on the periphery of the card. The pattern printing areas 12m to 12u may be arranged at equal intervals and the card punching areas are arranged at irregular intervals, or the pattern printing areas 12m to 12u may be arranged at uneven intervals and the card punching areas are arranged at equal intervals.

Pattern printing areas smaller in size than the ID card may be arranged at equal intervals on the sheet 11, and card punching areas may be arranged at irregular intervals so as to include the pattern printing areas. Alternatively, pattern printing areas smaller in size than the ID card may be arranged at irregular intervals, and the card punching areas may be arranged at equal intervals so as to include the pattern printing areas. According to such a method, a plurality of ID cards punched from the sheet 11 have patterns printed in different positions. Further, since no pattern remains on the used sheet 11, it is easy to dispose of it.

It should be noted that the present invention is not limited to the above-described embodiments as they are, but can be implemented by modifying the constituent elements within the scope of the invention at the implementation stage. Moreover, various inventions can be formed by appropriately combining the plurality of components disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiments. Furthermore, components of different embodiments may be combined as appropriate.
