DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scratch-off lottery ticket in which all of a lottery pattern and a concealing layer are formed by an offset printing method using process color ink.

[0002]

2. Description of the Related Art Heretofore, lottery tickets such as lottery tickets, entrance tickets, game tickets, etc., which are hit by lottery patterns such as numbers, characters, patterns, and the like to determine a loss, have been known. For example, as shown in FIG. 4, the lottery section area on which the lottery pattern 32 formed by characters, numbers, patterns, and the like indicating the loss is printed on the base material 31 so as to cover the lottery section area. A lottery ticket provided with a concealed image portion 34 by printing with a transparent resin layer 33 and an ink having a scratch property (which can be easily scraped off with a coin or the like) so that the lottery pattern 32 in the area cannot be seen on the transparent resin layer 33; Lottery tickets are known. The user of this lottery ticket can scrape off the concealed image part 34 covering the lottery part area and identify the content of the lottery pattern 32 to confirm whether it is a winning ticket or a lost ticket. Lottery tickets have been put to practical use.

[0003] However, so-called forgery or tampering has occurred in which lottery patterns such as these numbers, characters, patterns, etc. are changed or modified to falsify a lost ticket into a winning ticket. For this reason, these securities have been subjected to forgery-prevention printing such as tint block and fine print, or forgery prevention by printing with special ink. However, the anti-counterfeiting effect and the ease of authenticity confirmation have not always been satisfactory.

Therefore, the applicants of the present application have made a metal foil as an intermediate layer, bonded papers on both sides thereof, applied desired printing on one side of the paper, and included a part of the printing containing a colored pigment and a fluorescent dye. A ticket printed with an ink and provided with an overcoat layer made of a transparent varnish on a printing section made of the ink containing the fluorescent dye, wherein the fluorescent dye is printed from the printing section in the thickness direction of the overcoat layer and the paper layer. In the range reaching the metal foil with, for example, even if the number is falsified, the fluorescent dye remains in the shape of the base number, so it can be tampered with by illuminating with the light beam for emission Can be easily determined, counterfeit prevention measures have been implemented
No. 907 has been disclosed and put to practical use.

As described above, the current scratch-off lottery has been sufficiently protected against forgery of the lottery pattern in the lottery area. However, the layer covering the lottery area is made of a metal powder such as aluminum. A concealing layer having a scratch property is formed by screen printing using a highly concealable rubber-based ink (for example, a silver ink or the like), and a simple image is formed on the layer by using a process ink of one or two colors. It was a countermeasure to prevent forgery and tampering with commercially available seals.

[0006]

However, this concealed image portion has a high concealing property, but is restricted by design because it uses rubber-based silver ink kneaded with metal powder such as aluminum. Because of printing, the production capacity was inferior to that of normal offset printing. Also,
When multi-color printing with process ink is performed on the concealed image area,
There is also a problem that the surface of the concealed image portion is solidified and the scratch property is reduced. Further, the printing on the concealed image portion has a problem that the production cost of the lottery ticket increases by increasing one color.

Accordingly, the present invention has been made in view of the above-mentioned problems, and when an oil-based ink layer is superimposed on an ultraviolet curing type (hereinafter, referred to as UV) ink of a normal process color ink to perform printing, both layers are printed. Focusing on the point that adhesion is low (scratching occurs), and to provide a scratch-off lottery ticket in which a lottery pattern, a hiding layer, and other picture layers are all formed by a printing method using UV ink and oil-based ink. is there.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method of forming characters, numbers, patterns, etc., for displaying a loss or the like on a substrate made of paper, a resin sheet or the like. A lottery ticket provided with a lottery pattern, and a concealing layer provided so as to cover the lottery pattern, wherein the base pattern portion and the lottery pattern are printed with an ultraviolet curing (UV) ink; A scratch-off lottery ticket characterized by being printed with a black process ink and having the concealing layer at a PCS concentration of 0.9 or more.

The scratch-off lottery ticket according to claim 1, wherein the base pattern portion and the lottery pattern are printed with an oily process ink, and the concealing layer is printed with a black UV ink. is there.

[0010] In the scratch-off ticket according to claim 1 or 2, a UV is applied so as to cover the concealing layer.
It is characterized in that a full-color (multicolor printing) picture portion is provided with ink or oil-based ink.
