Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a label suitable for recording a barcode with invisible ink, and more particularly to a method for producing a label using a transparent film substrate. The present invention also relates to a label manufactured by such a manufacturing method.

[0002]

2. Description of the Related Art In recent years, it has been widely practiced to obtain personal information from various cards or to obtain product information described in products and catalogs by reading a printed barcode by optical means. A common barcode currently in widespread use is a barcode using a carbon black material and composed of a white bar and a black bar. However, such barcodes can be easily recognized by the naked eye,
In some cases, the information is read improperly or the design of a product box or the like may hinder the design.

[0003] For this reason, a bar code that is invisible, for example, a bar code called a stealth bar code, which is colorless, highly transparent, and hard to be seen by the naked eye, has been developed. Such a stealth barcode is formed, for example, by printing a barcode composed of a photoluminescence layer using a phosphor emitting in the infrared wavelength region on a printed material such as a catalog. Here, "stealth" is a registered trademark of Hitachi Maxell, Ltd., and "stealth barcode" is a registered trademark of Pioneer Corporation.

In reading the above-mentioned stealth bar code, the reader emits excitation light in the infrared wavelength range, and the phosphor contained in the stealth bar code reads emitted light emitted in response to the excitation light. Japanese Patent Application Publication (JP-A) No. 3-290780 discloses a stealth barcode recording material manufactured by forming a colorless and transparent substance that reflects infrared light on a substrate that transmits infrared light. And the reading method is published. Thus, a stealth barcode cannot be read without using a dedicated reader. Because of these features,
Stealth barcodes are used for applications in which security is important, such as prevention of forgery or falsification and confidentiality of information, such as various cards and tickets. In addition, since it has high transparency and can read a barcode from overprinting even when overprinting, it is also used in applications where the design of a decorative box or catalog of a product is important.

[0005] An example of an application in which security is emphasized is use in a pachinko game machine. In pachinko gaming machines, various legal regulations are set in order to maintain the fairness of the game. For example, after manufacturing an electronic board used for a pachinko gaming machine, R
A label for preventing unauthorized replacement is attached to the OM so that the ROM can identify an electronic board that has been incorrectly replaced.

However, in recent years, crimes in which a ROM is illegally removed and replaced with a fake ROM and a forged improper replacement prevention label is attached have become widespread.
In order to cope with such an act, a pachinko machine manufacturer has covered the entire ROM attached to the board with a transparent protective cover so that the ROM cannot be removed. Furthermore, based on the regulations of the law, a management label specified by the Security Electronics and Communications Technology Association (hereinafter, abbreviated as “TSC”) is attached to the protective cover. This management label,
It is specified for each assembly including a board, a ROM, a board, and a frame.

[0007] In addition to the above management label, a ROM
In order to determine a model corresponding to the above, a product label on which a product name, a lot number, a production date, and the like are printed is attached to the protective cover in a state where the ROM is covered with the protective cover after the board unit is created.

[0008] By the way, the pachinko machine maker is R
It is necessary to report the ID of the OM and the control number of the assembly unit of the pachinko gaming machine to the Police Agency. When requested by the Police Service Agency, the ROM ID and the control number of the assembly unit must be answered at any time. Therefore, it is necessary that the ID of the ROM can be visually recognized from outside the protective cover.

However, since the protective cover for covering the ROM is intended to prevent unauthorized removal of the ROM and to protect the ROM, the size of the protective cover is minimal enough to cover the ROM. If a plurality of types of labels, such as the management label specified by the above-mentioned security association and the product label indicating the contents of the ROM, are attached to such a protective cover, the appearance will deteriorate, and the contents will be removed from outside the protective cover. Will be invisible.

[0010]

For this reason, it is conceivable to manufacture a label by printing a stealth bar code having high security on a transparent film substrate which does not hinder visual recognition. Generally, in printing a stealth barcode, stealth ink is transferred to a substrate using a stealth ink ribbon. The base material needs to be capable of transferring a stealth ink ribbon and reading a stealth bar code by a dedicated reader.
However, when printing is performed using a stealth ink ribbon on a normal transparent film substrate, reading by a dedicated reader becomes impossible. Furthermore, in this case,
The stealth barcode looks thin even with the naked eye, making it impossible to ensure concealment.

In view of the above, it is an object of the present invention to provide a method of manufacturing a label using a transparent base material, the label being capable of reading printed information by emitting and emitting infrared light. . Another object of the present invention is to provide a method for producing a label using a transparent substrate, which can maintain the concealment of print information. Another object of the present invention is to provide a label manufactured using such a manufacturing method.

[0012]

In order to solve the above-mentioned problems, a label manufacturing method according to the present invention prints a silver ink on a predetermined area of a transparent film substrate on which printing is performed with an invisible ink. Thus, a step (a) of forming a silver ink layer on a transparent film substrate and a step of forming a white ink layer on the silver ink layer by overlaying and printing white ink on the silver ink layer ( b)
And (c) forming a transparent film layer covering the white ink layer by subjecting the transparent film substrate to a laminating process, and forming a print layer on a predetermined region of the transparent film substrate from above the transparent film layer. (D).

[0013] The label according to the present invention comprises a transparent film substrate, and a silver ink layer formed in a predetermined area of the transparent film substrate on which printing is performed with invisible ink.
A white ink layer formed on the silver ink layer, a transparent film layer formed so as to cover the white ink layer, and a print layer in a predetermined region of the transparent film substrate from above the transparent film layer. .

According to the present invention, a bar code or the like is printed with invisible ink after printing silver and white ink on a transparent film substrate, so that a stealth bar code can be read by a reader. In addition, it is possible to provide a label which is hard to visually recognize and can keep the concealment of the print information.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
It is a perspective view which shows a part of continuous body containing the label which concerns on 1st Embodiment. The continuum includes a mount 90 and a plurality of labels 100 temporarily attached on the mount 90. Label 1
In the stealth printing area 110 of 00, a stealth barcode which cannot be recognized by the naked eye is printed. The normal printing area 120 of the label 100 is an area for printing characters, marks, pictures, and the like (hereinafter, referred to as “characters”) such as notices that can be recognized by the naked eye. In the normal printing area 120, characters and the like can be printed on the side of the user who uses the label.

FIG. 2 is a sectional view of the label shown in FIG. As shown in FIG. 2, transparent PET used as a substrate
(Polyethylene terephthalate) tack paper is 90
Is a continuous body in which a transparent PET layer 102 is formed via an adhesive layer 101. Label 100 has silver and white ink layers 103-1 printed on transparent PET tack paper.
05, a transparent film layer 106, and a print layer 107 formed by printing a stealth barcode.

In this embodiment, ink is printed in three layers in the stealth print area 110 of the label 100. The lowermost silver ink layer 103 is printed to prevent transmission of light in the stealth print area 110. That is, light transmission cannot be sufficiently prevented only by performing white printing twice on the transparent PET layer 102, and the concealing property of print information is also insufficient, but the silver ink layer 103 is formed as the lowermost layer. By providing such a cover, it is possible to secure a safe value in reading the stealth barcode and to enhance the concealment of the print information.

The first white ink layer 104 and the second white ink layer 105 superimposed on the silver ink layer 103 color the stealth print area 110 in white, so that the opacity of the ink by transfer from the stealth ribbon is improved. This is to ensure the function. By printing the silver ink layer 103 and the white ink layers 104 and 105, the stealth barcode to be printed can be read,
It becomes difficult to visually recognize the barcode with the naked eye. In addition,
Depending on the printing conditions, the second white ink layer 105 may be omitted.

A first transparent film layer 106 is formed on the white ink layer 105 by laminating. This is because if the stealth ink is transferred and printed directly on the printed white ink layer 105 via a stealth ribbon, the white ink may be melted and the accuracy of the barcode may be reduced, making reading difficult. This is for coating the white ink layer with the layer 106. As such a transparent film layer 106, for example, a transparent PET film having a thickness of 16 μm can be used.

On the transparent film layer 106, a stealth ink containing a phosphor which emits light in an infrared wavelength region having a wavelength different from that of the excitation light when irradiated with excitation light in the infrared wavelength region is transferred from the stealth ribbon. It is printed as a code. Thereby, the print layer 107 is formed. The information printed on the print layer 107 may be characters readable by a reader, an authentication mark, or the like, in addition to the barcode.
