Description

[Detailed explanation of the invention] This invention relates to voting tickets with anti-counterfeiting measures.
More specifically, under natural light they appear to be the same color tone, but by using a specific optical filter,
The present invention relates to a voting ticket which has anti-counterfeiting measures by combining ink that is visible as is and patterns using ink that becomes invisible or becomes difficult to see.

Traditionally, voting tickets for horse racing, bicycle racing, and boat racing have information on the front of the ticket, such as the annual event, the event date, and
Voting details such as amount, race number, winning number, organizer, ticket issuing machine number, serial number, etc. are displayed in advance by printing, processing, or printing using the ink ribbon or ink roller of the ticket issuing machine, so that they can be easily understood by voters. provided voting ticket information. Furthermore, it was common to display the expiration date and the lot number for producing the voting ticket on the back of the voting ticket.

However, such voting tickets and ticket issuing systems have a problem in that winning tickets can be forged or altered. Such falsification generally involves peeling off the surface layer of the display part of the winning ticket, or erasing it in some other way and altering it to display the winning ticket.
More often, the surface layer of the winning ticket equivalent display part of another winning ticket is peeled off and the display part is pasted on the erased winning ticket.

Measures to prevent such falsification include using penetrating ink on the ink ribbon or ink roller, which is generally used to provide information on winning or losing voting tickets, and using penetrating ink on the voting ticket paper, which exhibits absorbency due to capillary action. A method has been adopted in which a suitable fibrous paper is used to provide markings in the thickness direction of the paper, making it difficult to erase or alter the markings.

However, this method has drawbacks such as blurring of the display due to ink bleeding in the direction of the paper surface and ink penetration being hindered by repeated use of the ink ribbon.

The present invention overcomes the drawbacks of the conventional ticket issuing system described above and provides a means for making it difficult to forge or alter voting tickets.

In other words, the present invention uses two or more types of inks (hereinafter simply referred to as conditions) that have the same color tone in the visible region and have different reflectances for light that passes through a filter that transmits only light in a specific wavelength range in the visible region. The gist of the voting ticket is a voting ticket characterized by having two or more types of patterns formed on the paper using the same color ink (sometimes referred to as the same color ink).

Therefore, in the present invention, two or more colors have the same tone under natural light but have different spectral curves, and the same color ink is arbitrarily placed in each part of the pattern such as letters and patterns on the voting ticket. It is characterized by a kind of hidden printing that appears to be the same color to the naked eye.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are plan views of the voting ticket A of the present invention, respectively. In FIGS. 1 and 4, reference numeral 1 indicates a voting ticket paper, and reference numerals 2 and 3 and 4 and 5 indicate combination patterns of conditional isochromatic inks, respectively. That is, in FIG. 1, combinations of color-matching ink patterns are shown as free curves, and ink 2 and ink 3 are shown in every other curve. In Figure 4, the combination of conditional color ink patterns is character pattern 1.
Every other time, ink 4 and ink 5 are selected.
Of course, the pattern based on the conditional color ink combination is not limited to the embodiments shown in FIGS. 1 and 4, and patterns can be freely combined.

The color-matching inks used in the present invention include, for example, two or more inks that have the same color tone in the visible region and have different reflectances for light that passes through a filter that transmits only light with a wavelength of about 650 mμ or more. used. Examples of this include cationic dye (Violet F3RL) 80 parts by weight (hereinafter simply referred to as "parts"), oil dye (Yellow
7GLL) 10 parts and oil dye (Black BN) 10 parts
Dye composition P consisting of
These dye compositions P or Q8
1 part, 26 parts of polyamide resin and benzyl alcohol
There are two types of ink made by kneading 66 parts. or,
Other examples include acid dyes (violet FBW)
Dye R consisting of 46 parts of acid dye (Blue 6B),
Using a dye composition S consisting of 36 parts of acid dye (Violet F6R) and 18 parts of acid dye (FBW),
There are two kinds of inks made by kneading 5 parts of these dyes R or dye composition S, 20 parts of maleic acid resin, and 75 parts of a 10% aqueous solution of thioethylene glycol.

Now, in Figures 1 and 4, the voting ticket A is issued only after the voting ticket information 6 is printed on a ribbon or in advance. A structure as shown in Figure 7 was prepared. In Figure 7, 7 is an incandescent light bulb, 8 is an optical filter, 9 is a peephole,
10 is a light shielding case. A voting ticket A as shown in FIGS. 1 and 4 is set in the position shown in FIG. The state is shown in FIG. 2 or FIG. 5. Under natural light, the pattern 3 or 5 whose printing ink spectral characteristics are similar to the spectral characteristics of the light source selected by the filter 8 becomes invisible, and the printed pattern 2 or 4, which has different spectral characteristics, becomes visible with emphasis. 3 and patterns 4 and 5 appear to have the same color tone, selectivity in the visibility of the patterns appears by changing the spectral characteristics of the light source.

Furthermore, if the ink spectral characteristics of the voting ticket information characters formed by a ribbon, an ink roller, or pre-printing are made similar to the light source spectral characteristics, a simpler pattern is selected as shown in FIG. 3 or FIG. 6. When the pattern appears simplified as shown in FIGS. 3 and 6, there is an advantage that it becomes much easier to detect counterfeit tickets.

As described in detail above, according to the present invention, when rewriting the voting ticket information with an eraser or the like to forge a losing ticket into a winning ticket, part of the pattern as shown in Figures 1 or 4 can be replaced with a commercially available suitable When correction is made using a coloring material with specific spectral characteristics, an inappropriate pattern may occur at a position other than the intended pattern position, such as missing ink pattern 2 or 4 in Figure 3 or Figure 6. This makes it easier to detect forgeries.

Although the present invention focuses on voting tickets, the purpose of preventing forgery of the present invention can also be applied to forms, cash vouchers, securities, tags, etc.
