JP4612503B2 - Printed material with confidential information - Google Patents

Description

  The present invention relates to a printed matter having confidential information in which an area in which confidential information is invisible is disguised with a watermark pattern.

Conventionally, as a means of invisibility of information to be concealed, a method of printing using colorless fluorescent ink, or information to be concealed is printed with colored ink, and on top of it is ink with a large shielding property. A coating method such as scratch printing is used.
Information printed using colorless fluorescent ink is visualized by ultraviolet irradiation, and information invisible with a scratch material is visualized by removing the covering portion with a coin or the like.
The invisibility of information by the scratch printing method has a drawback that when the printed substrate is thin, it is visible from the back of the substrate, and there is a problem that relatively thick paper must be used. When thick paper could not be used, aluminum foil was bonded between the two thin papers to compensate for the shortcomings of the thin paper (see, for example, Patent Document 1).
According to the technique described in Patent Document 1, a lottery ticket base material is formed by forming a metal layer having a large light shielding property between thin papers, and lottery information is printed on the base material. The lottery information is shielded. In this technology, since a metal layer having a large light shielding property is formed between thin papers, curling is likely to occur on the base material, and defective products are likely to be generated during the manufacturing process. Therefore, the material cost is high.

Therefore, a scratch printed material is provided that is an inexpensive base material and is unlikely to generate a defective product due to curling in the manufacturing process (see, for example, Patent Document 2).
According to the technique described in Patent Document 2, in order to solve the problems of the technique described in Patent Document 1, the content is concealed on at least a part of the upper surface of the first sheet-like base material with poor concealment. A scratch concealing layer that can be scratched to cover the top of the print is laminated, and is formed on the lower surface of the first sheet-like base material at a position corresponding to the printing on the upper surface. The present invention provides a scratch-printed product in which a second sheet-like substrate having poor concealment property is laminated through a light shielding layer comprising a composition containing the light-shielding colorant in a resin vehicle.

Hereinafter, the printed matter having the confidential information of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining an example of a printed matter having confidential information of the present invention, FIG. 2 is a diagram for explaining a cross section taken along the line CC of FIG. 1, and FIG. 3 is a diagram for explaining confidential information of the present invention. FIG. 4 is a diagram for explaining an example of watermark printing of a printed matter, and FIG. 4 is a diagram for explaining another example of watermark printing of a printed matter having confidential information according to the present invention.

With reference to FIG. 1, an example of a printed matter having confidential information according to the present invention will be described.
As shown in the figure, the printed matter 1 having confidential information is a printed matter mainly composed of, for example, gift certificates, lottery tickets, scratch tickets, and the like.
Although the printed matter 1 having the confidential information is not shown, the confidential information 2 is formed on one side of the sheet-like base material that transmits light in the visible region. One pattern and a camouflage pattern having the same shape as the first pattern are formed, a second pattern is formed so as to cover the first pattern and the camouflage pattern, and a third pattern is covered so as to cover the second pattern Is formed.
On the surface of the third pattern, print information A13 such as “mark” and print information B12 specifying a printed matter such as “gift certificate” and “10,000 yen” are printed.
In the example of FIG. 1, the secret information 2, the first pattern (not shown) covering the secret information, and the print information A13 are printed so as to overlap, but the print information A13 is different from the first print area. In some cases, the image is printed in an area.
In the case of a printed matter having confidential information according to the present invention, an area where the confidential information is printed is removed except for a printed matter such as a scratched lot that removes the shielding layer that covers the confidential information and confirms “hits” and “miss”. There is little to specify.

With reference to FIG. 2, a cross section taken along line CC in FIG. 1 will be described.
As shown in the figure, the printed matter 1 having the confidential information includes a printing ink on which the confidential information 2 is printed on the surface of the sheet-like substrate 6, a printing ink of the first pattern 3 covering the confidential information 2, and the confidential information 2. Printed on the peeling pattern 7 printing ink formed between the first patterns, the imitation pattern 3d printing ink, the second pattern 4 printing ink, the third pattern 5 printing ink, and the third pattern. The printing ink of printing information A11 and the printing ink of printing information B12 are formed.

  The sheet-like substrate 6 is, for example, non-coated paper such as high-quality paper, medium-quality paper, lower grade paper, and colored high-quality paper, coated paper such as art paper, coated paper, and lightweight coated paper, embossed paper, cast coated paper , Kraft paper, various plastic films, etc., but since it is necessary to transmit light in the visible region, when a relatively thick substrate is selected, an inorganic paint is applied to the surface of the substrate. Select from uncoated uncoated paper.

For example, in the case of a lottery, the confidential information 2 is character information such as “winning” and “out of”, and character information such as “1st”, “2nd”, “3rd”, and the like.
In the case of a lottery ticket or the like, number information using numbers in which alphabets and kana are mixed is the mainstream.
When printing as watermark information, information associated with other information printed on the printed matter 1 having confidential information is printed.

  The first pattern 3 and the camouflaged pattern 3d have the same shape in order to camouflage the presence of the first pattern shielding the confidential information. The camouflaged pattern 3d is preferably printed with the same ink as the first pattern for the same reason as described above, and is printed together with the first pattern on the same plate.

  The ink for printing the first pattern 3 (hereinafter also referred to as the shielding layer 3) is required to have high shielding properties in order to make the confidential information 2 invisible, and silk screen ink is preferably used. Printing ink for printing the shielding layer is selected from resins such as acrylic resin, vinyl resin, rubber resin, diene resin, etc., and vehicles are produced, and colored pigments and shielding effects are applied to these vehicles. For example, a metal such as aluminum, brass, or copper, or fine powders of oxides thereof are added, and a solvent is added.

A peeling layer 7 may be formed between the shielding layer 3 and the secret information 2 to enhance the peeling effect of the shielding layer 3.
The release layer 7 is printed with a transparent offset ink so that the secret information 2 can be seen through.

The ink for forming the second pattern 4 “consisting of any one of marks, characters, designs, or combinations thereof” is matched to each suitable printing method such as offset ink, letterpress ink, flexographic ink, etc. To select.
In the description relating to the printing of the camouflaged pattern 3d, it has been described that the camouflaged pattern 3d is preferably printed together with the first pattern. However, the ink for printing the second pattern has high shielding properties. In this case, the camouflaged pattern 3d and the second pattern may be printed together on the same plate.

Since the 3rd pattern 5 is a pattern formed in the one surface whole surface of the printed matter (gift certificate) which has confidential information, the ink used for the printing of the 3rd pattern 5 has moderate transparency. It is necessary to be.
Also, the ink used for printing the printing information A and B formed on the surface must be easy to be adapted.
For this reason, offset ink, letterpress ink, flexographic ink, and the like used for the second pattern printing are used, and each is formed by a suitable printing method.

  When printing the printing information A and B formed on the outermost surface, the above-described offset ink, letterpress ink, flexographic ink, and the like are used, and each is formed by a suitable printing method.

With reference to FIG. 3, an example of watermark printing of a printed matter having confidential information according to the present invention will be described.
The printed matter 10 having the confidential information shown in FIG. 3 shows a state before printing the print information A11 and the printed information B12 of FIG. 1, and the printed matter 10 having the confidential information is exposed to light from the sheet-like substrate side. It shows the state as viewed.
The printed matter 10 having the confidential information includes the confidential information 20 printed as “Tsumami”, the first pattern 30 formed to shield the confidential information, and two impersonation patterns having the same shape as the first pattern. 30d, the second pattern 40 by “one of marks, characters, designs, or a combination thereof” and a solid third pattern (not shown) are formed.
Since these pieces of information and patterns can be seen through when the printed material 10 having confidential information is exposed to light, the effect as a watermark is exhibited.

In the figure, the confidential information 20 is shown in a visible state as “Ten thousand”, but the confidential information printed with “gray” offset ink is, for example, the “gray” silk screen ink containing metal powder or the like. Since it is integrated with the shielding layer, it is actually invisible.
The printing color of the second pattern 40 is printed with a dark color (for example, “gray” offset ink) approximate to the first pattern 30 and the camouflaged pattern 30d. The camouflaged pattern and the second pattern are recognized as integrated patterns, and it is difficult to find that the confidential information 20 is printed.

With reference to FIG. 4, another example of watermark printing of a printed matter having confidential information according to the present invention will be described.
The printed matter 100 having the confidential information shown in FIG. 4 is an example in which the second pattern 40 described in FIG. 3 is inverted to the “negative state”.
On the printed matter 100 having confidential information, the confidential information 200 printed as “Ten thousand”, the first pattern 300 formed to shield the confidential information, and two impersonation patterns having the same shape as the first pattern A second pattern 400 is formed by 300d, “any of marks, characters, designs, or a combination thereof”, and a solid third pattern (not shown) is formed.
Since these pieces of information and patterns can be seen through the printed material 100 having confidential information by illuminating it with light, an effect as a watermark is exhibited.

As in the case of FIG. 3, the confidential information 200 is shown in a visible state as “Samurai”, but is actually invisible for the same reason as described in FIG. 3.
Further, since the printing color of the second pattern 400 is printed with a dark color (for example, “gray” offset ink) approximate to the first pattern 300 and the camouflaged pattern 300d, The camouflaged pattern and the second pattern are recognized as integrated patterns, and it is difficult to find that the confidential information 200 is printed.

81.4 g / mm ² high-quality paper is used as the sheet-like substrate, confidential information consisting of 4-digit numbers is printed by the offset printing method, and further by the offset printing method (by a solid pattern covering the confidential information) The release layer was printed.
In addition, a shielding layer (scratch layer) and a camouflaged pattern are printed by a silk screen printing method, and a background pattern with numbers scattered as a second pattern is printed over the entire sheet-like base material. A solid pattern was printed.
The secret information and the second pattern were printed in “gray” using a commercially available UV (ultraviolet) curable offset ink.
The release pattern was printed with “colorless” using a commercially available UV curable offset ink.
The shielding layer and the camouflaged pattern were printed in gray using shielding ink (silk screen ink) manufactured by Teikoku Ink Mfg. Co., Ltd.
The third pattern was printed “white” using a commercially available mat type UV curable offset ink.
The text information of “gift certificate test” was printed on the third pattern, and a printed matter having confidential information was made as a prototype.

The “printing effect of confidential information” and the “watermark effect” were confirmed by the printed matter having the secret information manufactured as a prototype.
Moreover, the shielding layer of the part which printed confidential information was removed with the corner of the coin from the top of the white ink (third pattern printing ink), and it was confirmed that the confidential information can be clearly displayed.

  INDUSTRIAL APPLICABILITY The present invention can be used as a printing substrate for money vouchers such as gift certificates, and for an instant lottery ticket, lottery ticket, or the like in which a scratch portion is removed to confirm “winning / losing”.
