Description

The present invention relates to an anti-counterfeit medium that can be applied to valuable items such as banknotes, passports, securities, stamps, product tags, toll road tickets, and various tickets.

Anti-counterfeiting technology has been applied to valuable goods such as banknotes, passports, securities, stamps, product tags, toll road tickets, and various tickets. Therefore, authenticity determination is performed on such valuables by attaching a transfer foil such as a hologram to the surface of the base material. Threads, holograms, and the like made of optically changing elements are one of anti-counterfeiting elements that are particularly effective from the viewpoint of copy prevention and copy prevention, and have been applied to many valuable items.

As a technique in which a thread is used, for example, a forgery prevention paper is disclosed in which a thread formed by slitting a sheet having a multilayer thin film layer on a base material is slit into a base paper (see Patent Document 1). ).

As a technique in which a hologram is used, for example, an anti-counterfeit label in which a hologram transfer foil layer is formed on the surface of a base material is disclosed (see Patent Document 2).

In addition, there is disclosed a hologram-attached securities characterized in that in a securities provided with a hologram, a different pattern is engraved on each leaf like a split between the hologram and the paper (see Patent Document 3).

Further, it is a precious printed matter composed of a base material and a sheet of the optically variable element attached to one surface of the base material, and the base material includes a portion to which the sheet is attached. A plurality of holes are formed through the laser beam, and the plurality of holes can be confirmed from the front side / rear side where the sheet is attached. There is disclosed a valuable printed matter characterized in that the material and the sheet of the optically variable element have a structure in which a plurality of holes are formed so that the material is broken and cannot be restored (see Patent Document 4). .

Furthermore, it is a heterogeneous combination voucher that combines a first voucher, an admission ticket, a gift certificate, etc. and a second voucher, a stamp, a stamp, or a seal, and the second voucher is included in the first voucher. One or more are formed. A perforation is provided around the second voucher so that the second voucher can be separated from the first voucher, and a hologram, a thread, A technique for applying anti-counterfeiting (authentication) means such as a barcode is disclosed (see Patent Document 5).

Japanese Patent Laid-Open No. 10-10053 (pages 1-7, FIGS. 1 and 2) JP 61-182580 A (1st page, Fig. 1-4) JP 2000-355183 A (page 1-3, FIGS. 1 and 2) Japanese Patent No. 3336378 (pages 1-6, FIGS. 5 and 6) JP 2003-136872 A (page 1-4, FIG. 1-8)

As in Patent Document 2 (Japanese Patent Application Laid-Open No. 61-182580), simply attaching a hologram to a base material may cause forgery or tampering. For this reason, as disclosed in Patent Document 3 (Japanese Patent Laid-Open No. 2000-355183), a technique for preventing an act of imprinting a pattern between a hologram and a base material and peeling off the hologram to prevent falsification is disclosed. . The information of the mark can be confirmed with the naked eye, and since it is formed by printing, there is a possibility that the mark is easily duplicated. In addition, there is a possibility of duplication in the same manner as described above with a thread-only technique as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 10-100533). Patent Document 4 (Japanese Patent No. 3336378) did not describe any form of tally. Patent Document 5 (Japanese Patent Laid-Open No. 2003-136872) is provided with perforations in the hologram, but is for perforation or separation, and is not intended to prevent the separation of the hologram. For this reason, it is excellent in prevention of peeling, and even if it is attached to a medium that has been peeled off and invalidated, even if the medium is counterfeited, the medium has an anti-counterfeiting effect and a high authenticity discrimination effect. Has been required.

The present invention is intended to solve the above-described problems, and in an anti-counterfeit medium in which an optical change element is provided on a part of the base material, the optical change element is provided on a part of the base material. An anti-counterfeit medium excellent in anti-peeling, anti-tampering, anti-duplication, and anti-counterfeiting effect, in which a tally image is formed by a fine perforation group across the boundary between the area to which the optical change element is not applied It is what we propose.

The present invention relates to a forgery prevention medium in which a part of a base material is provided with an optical change element, wherein the part of the base material is provided with a region provided with the optical change element and the optical change element. This is an anti-counterfeit medium in which a split image is formed by fine perforations so as to sandwich a boundary of a non-region.

The present invention relates to an anti-counterfeit medium in which an optical change element is provided on a part of a base material, and a boundary between a region where an optical change element is provided on a part of the base material and an area where no optical change element is provided. Is a forgery prevention medium in which a tally image is formed by a fine perforation group without applying a seal or printing as in the past, and by a perforation group finer than a tally that is formed by a conventional seal or printing It is difficult to duplicate because it forms a tally.

The anti-counterfeit medium of the present invention, when trying to peel off the optically changing element, the optically changing element is destroyed and cannot be reused, even if it is peeled off and pasted to an invalid medium, The area where the optically variable element is not applied because the split image is formed by a fine perforation group across the boundary between the area where the optically variable element is applied and the area where the optically variable element is not applied It cannot be tampered with because it does not match the perforated group formed on the surface.

The anti-counterfeit medium according to the present invention is difficult to discriminate authenticity because the optical change element is not provided when the optical change element is peeled off in the course of distribution. Since a perforation group is formed in a region where no is given, authenticity determination is possible depending on the presence or absence of the perforation group.

In the anti-counterfeit medium of the present invention, a variation is obtained in the information forming method by forming a tally image with fine perforations, for example, visual information by forming letters, numbers, symbols, designs, etc. By changing at least one of the size, shape, and interval of the perforations, it is impossible to see and is discriminated by the machine. It can be authenticated.

From the above, the anti-counterfeit medium of the present invention is excellent in anti-peeling effect, anti-falsification effect, anti-duplication effect, authenticity discrimination effect, banknotes, passports, securities, stamps, product tags, toll roads, etc. It can be applied to valuables such as coupon tickets and various tickets.

The best mode for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the best mode for carrying out the invention described below, and includes various other embodiments within the scope of the technical idea described in the scope of claims.

(Forgery prevention medium)
In FIG. 1, the optical change element (2) is affixed to the surface of the substrate (1) in a spot shape, and the region where the optical change element (2) is affixed and the optical change element (2) are not affixed An anti-counterfeit medium (A1) in which a tally image is formed by fine perforated groups (3) across a region boundary and a cross-sectional view thereof are shown. The fine perforated group (3) penetrates the optically variable element (2) and the substrate (1).

(Modification 1)
The present invention is not limited to the anti-counterfeit medium (A1) shown in FIG. 1, and the fine perforation group (3) like the anti-counterfeit medium (A2) shown in FIG. It does not have to penetrate through the substrate (1).

(Modification 2)
In FIG. 3, the boundary between the region where the optical change element (2) is inserted and the region where the optical change element (2) is not inserted is inserted into the band of the base material (1). The forgery prevention medium (A3) formed by the perforated group (3) in which the split image is fine with the image sandwiched therebetween and a sectional view thereof are shown. The fine perforated group (3) penetrates the optically variable element (2) and the substrate (1).

(Modification 3)
The present invention is not limited to the anti-counterfeit medium (A3) shown in FIG. 3, and the fine perforation group (3) like the anti-counterfeit medium (A4) shown in FIG. It does not have to penetrate through the substrate (1).

(Modification 4)
The optically variable element (2) formed in a band shape may be shaped like a forgery prevention medium (A5) shown in FIG.

The optically variable element can use an aluminum foil or a hologram having a diffraction grating on the aluminum foil, and the hologram is not particularly limited, such as a transmission hologram or a reflection hologram. Further, the shape of the optically variable element is not particularly limited, such as a circular shape, an elliptical shape, a polygonal shape, a special shape such as a star shape, or a thread shape. Therefore, it can be read by at least one sensor such as reflected light, transmitted light, and magnetism.

The index image formed by the fine perforations can be formed by laser light from a laser processing machine, and the type of laser is not particularly limited, such as YAG laser or carbon dioxide laser. The information of the tally image is not particularly limited, but it is possible to form a plurality of perforations, image lines, etc., and form characters, symbols, numbers, colored patterns, logo marks, designs, or the like. When the split image is formed by perforation, the diameter of each perforation is preferably formed in the range of 50 μm to 1000 μm, and the pitch of the perforations is preferably formed in the range of 100 μm to 2000 μm. The shape of the perforations can be formed by a circle diameter, an ellipse, a polygon and a special shape or a combination thereof. Further, the information formed on the anti-counterfeit medium can be variable information for each sheet. For example, the numbers may be different, such as “12345” for the first sheet and “12346” for the second sheet. The index formed on the anti-counterfeit medium is difficult to duplicate by forming with fine perforations. Further, since the index formed on the forgery prevention medium is formed by a laser processing machine, variable information can be easily formed.

In addition, the index image of the forgery prevention medium of the present invention can be given information by the perforation group. An example is shown below. As shown in FIG. 6, the perforation group (3A) includes a large number of fine background perforations (12) that form a background image that is difficult to see on the base material, and a latent image for the background perforations (12). The information perforations (13) arranged to be shifted in the X direction are formed. Further, as shown in FIG. 7, the perforation group (3B) includes a large number of fine background perforations (12) that form a background image that is difficult to see on the base material, and a latent image with respect to the background perforations (12). The first information perforations (13A) arranged to be shifted in the X direction and the second information perforations (13B) arranged to be shifted in the Y direction are formed. In addition, as shown in FIG. 8, the perforation group (3C) has a large number of fine background perforations (12) that become a background image that is difficult to see on the substrate (11) and a latent image. It is formed by information perforation (13) having a different perforation size compared to perforation (12). In this case, the shape of the perforations in the X direction or the Y direction may be different, and the shape of the perforations may be different as long as the sizes of the perforations in the X direction or the Y direction are different. In addition, as shown in FIG. 9, the perforation group (3D) has a large number of fine background perforations (12) that become a background image that is difficult to see on the base material (11) and a latent image. It is formed by the information perforation (13) having a different perforation shape compared to the perforation (12).

6 to 9, the drilling positions of the background drilling and the information drilling are shifted, the size is different, or the shape is different. However, since the drilling is fine, the background drilling and the information drilling are visually observed. It is not possible to visually distinguish them. The perforated group in FIG. 6 or FIG. 7 allows the latent image to be visually recognized by superimposing the discriminating tools formed with stripes extending in the vertical or horizontal direction, and the perforated group in FIG. 8 or FIG. The latent image can be visually recognized by observing at an angle. For example, the discriminating tool in which stripe lines are formed can be formed by, for example, YCM (yellow, cyan, magenta), YCM, YCM,... In the order of stripes extending in the vertical or horizontal direction, or RGB (red, green, Yellow), RGB, RGB... Can be formed in the order of stripes extending in the vertical direction or the horizontal direction, or lines can be formed by unevenness.

  Furthermore, the tally information of the anti-counterfeit medium of the present invention can embed confidential information in the perforation group. An example is shown below. The circles and polygons in the drawings described in FIGS. 10A to 10D are perforations. FIG. 10A is an example in which “0” and “1” are expressed by the row perforation intervals, and the perforation intervals (S, S ′) in the second row from the top are wide (S). The perforation interval is divided into narrower (S ′) than the perforation interval (S), and the perforation intervals are large, large, large, small, small, and small, and thus, “111000” or “000111”. Information can be expressed. Similarly, the punching intervals (S, S ′) in the third row are the small, large, large, small, small, and large punching intervals, thereby expressing information as “011001” or “100110”. be able to. Information can be similarly assigned to the first line and the fourth and subsequent lines.

  FIG. 10B is an example in which “0” and “1” are expressed by the positions of the drilling holes. When the drilling position (T) of the first line is used as a reference position, If the perforation (U ′) shifted from the perforation position (T) in the first row is “1” and the perforation (U) not shifted is “0”, the information can be expressed as “0101010”. it can. Also, if the perforation (U ′) shifted from the position (T) of the first line is “0” and the non-displaced perforation (U) is “1”, the information is expressed as “1010101”. Can do. Similarly, information can be given to the first row and the third and subsequent rows.

  FIG. 10C shows an example in which “0” and “1” are expressed according to the size of the perforation. In the perforation in the second row from the top, the large diameter perforation (V ′) is “1”, If the small perforation (V) is “0”, information can be expressed as “0101010”. In addition, when a large diameter perforation (V ′) is “0” and a small perforation (V) is “1”, information can be expressed as “1010101”. Information can be similarly assigned to the first row and the third and subsequent rows.

  FIG. 10D shows an example in which “0” and “1” are expressed depending on the type of perforation. In the perforation in the second row from the top, polygonal perforation (W ′) is “1”, a circular shape. When the perforation (W) is “0”, information can be expressed as “0101010”. If the polygonal perforation (W ′) is “0” and the circular perforation (W) is “1”, information can be expressed as “1010101”. Information can be similarly assigned to the first row and the third and subsequent rows.

  The perforation group in which the confidential information is embedded by the perforation group of FIGS. 10A to 10D is “a true / false discrimination forming body having fine perforations and a true / false discrimination device: see Japanese Patent Laid-Open No. 2000-233561. , Japanese Patent Laid-Open No. 2000-235631 ”,“ Anti-counterfeit forming body having a perforated row to which information is given and its reading discrimination method: see Japanese Patent Laid-Open No. 2000-233562 ”, and“ Authenticity having fine perforations ” Discrimination device: described in Japanese Patent Application Laid-Open No. 2001-138699. Therefore, different information (variable information) can be given for each medium.

  In the anti-counterfeit medium (A6) shown in FIG. 11, the individual print information (4) and the index image of the base material (1) are formed of fine perforations (3). The fine perforation group (3) is provided with secret information (5) that cannot be visually observed. FIG. 12 is an explanatory diagram of a method for authenticating the forgery prevention medium (A6). As shown in FIG. 12, in STEP1, the authentication client terminal reads the individual print information (4) and the confidential information (5). Confidential information can be read using the reading device described in “Reading device for binarized data given by fine punching: see Japanese Patent No. 3385357”, and printing information can read characters, designs, etc. It can be read by a general reading device.
