Description

  The present invention relates to a scratch printed matter on which a scratch concealment layer for concealing confidential data or the like is printed, and a scratch printing method.

  Conventionally, a scratch printed matter having a concealing layer for concealing confidential data such as a lottery result, a winning product name, an ID number, and a barcode printed on a lottery ticket or a prepaid card is known. The concealing layer has a concealing property for preventing the confidential data from being visually recognized from the outside, and a releasability for allowing the owner of the scratch printed matter to visually recognize the confidential data by rubbing with a coin or a nail.

  FIG. 6 is a schematic diagram showing a laminated cross section of a conventional scratch print 300. As shown in FIG. 6, the conventional scratch print 300 is such that confidential data 12 made up of numbers or the like is printed on the surface of a base material 11 such as paper or plastic, and a transparent peeling varnish or the like that covers the confidential data 12. A release layer 13 is formed, and a concealing layer 14 is applied on the release layer 13.

  When using a base material 11 with high light transmittance, such as thin paper, when the strong light is applied from the back surface of the base material 11, the shadow of the confidential data 12 may be seen through from the opposite surface, and the concealability There was a problem.

  In order to solve this problem, for example, the masking layer 14 can be formed by silk screen printing that can be printed with a thick ink layer, or the masking layer 14 can be overprinted by offset printing. It is conceivable to reduce the light transmittance of the hiding layer 14.

  In the technique described in Patent Document 1, a concealing layer 14 in which confidential data 12 is pressed into a normal printing color ink layer and a non-image area of the release layer 13 is proposed.

As shown in FIG. 2, the scratch printed material 100 is configured such that confidential data 12, a release layer 13, a dummy concealment layer 14 a, and a solid concealment layer 14 b are sequentially printed on a base material 11.

The method for printing the confidential data 12 on the substrate 11 is preferably an ink jet method capable of variable printing.
The method for printing the release layer 13, the dummy concealing layer 14a, and the solid concealing layer 14b on the substrate 11 is preferably a method capable of thin film printing. For example, in addition to offset printing, a gravure method with good production efficiency and a resin relief plate are used. The conventional roll coat method or flexo method is preferred.

  The substrate 11 may be paper or plastic. Examples of the paper include paper such as art paper, coated paper, and high-quality paper, and paperboard such as coated balls, coated manila, and double-sided cards. Examples of the plastic include white PET (polyethylene terephthalate), white PVC (polyvinyl chloride) sheet, and the like, which are appropriately selected according to the application. The effect of the present invention can be particularly exhibited in the base material 11 having high light transmittance.

  The ink forming the confidential data 12 is a normal black ink for printing, and is appropriately selected according to the base material 11.

  The ink for forming the release layer 13 is an ink in which the dummy concealing layer 14a and the solid concealing layer 14b are easily scratched off. For example, silicon or wax (polyethylene wax or the like) as an additive to a polyurethane acrylic resin, a polyamide resin, or a nitrocellulose resin. ) Is added about 5% by weight.

  Further, a release varnish obtained by adding about 5% by weight of a lubricant (silicon, polyethylene wax, etc.) to a printing ink vehicle (a component excluding coloring pigments and additives of the printing ink) may be used.

  The composition of the ink for forming the masking layers 14a and 14b is, for example, 15 to 25 parts by weight of aluminum powder for imparting masking property, 15 to 25 parts by weight of a color pigment including an extender pigment such as alumina white, ) 15-25 parts by weight of a synthetic rubber resin such as SBR and NBR, and 35 to 45 parts by weight of an aromatic hydrocarbon solvent such as toluene, xylene, and methyl isobutyl ketone, and an auxiliary agent such as an antifoaming agent 5 to 15 A weight part is added and it mixes according to each printing system.

Can also be used. The composition of the ink is, for example, an aluminum paste for imparting concealability and scratch properties (a fine aluminum powder is surface-treated with a fatty acid or the like and made into a paste form with a high boiling point mineral spirit or the like) and a color pigment of 20 to 45 parts by weight, 25 to 50 parts by weight of a polyurethane-based synthetic resin as a binder, and 1 to 10 parts by weight of an auxiliary agent such as an antifoaming agent are dispersed in 10 to 35 parts by weight of water and less than 5 parts by weight of isopropyl alcohol. Is mentioned. The ink composition for forming the masking layer 14a may be the same as or different from the ink composition of the masking layer 14b.

  Ordinary black ink may be used for the dummy masking layer 14a and the solid masking layer 14b. However, since black ink remains in the release layer, it is preferable to use silver ink for the dummy masking layer 14a and the solid masking layer 14b. When the dummy concealment layer 14a and the solid concealment layer 14b are printed thinly, even if the shadow of the confidential data 12 is reflected on the scratch print 100, the dummy characters of the dummy concealment layer 14a are also shadowed and reflected together, thereby concealing effect. There is.

  When printing the solid concealment layer 14b a plurality of times, the dummy concealment layer 14a may be printed a plurality of times after the dummy concealment layer 14a is printed on the substrate 11 and then the solid concealment layer 14b is printed a plurality of times. You may print so that it may pinch | interpose between.

  FIG. 3 is a diagram illustrating an example of a print pattern of each layer constituting the scratch printed material 100.

  As shown in FIG. 3A, the information included in the confidential data 12 is character information such as an ID number and a numbering (management number), and is printed by changing the information for each scratch card 1.

  The printed pattern of the release layer 13 is a uniform pattern that covers the confidential data 12 as shown in FIG.

As shown in FIG. 3C, the printing pattern of the dummy concealment layer 14a is an irregular arrangement pattern of characters such as numbers. The characters constituting the pattern of the dummy concealment layer 14a are preferably the same or similar font or / and the same or similar size as the characters included in the confidential data 12. Moreover, it is preferable to arrange the characters constituting the pattern of the dummy concealment layer 14a so as to overlap each other at a font size ratio.
The printing pattern of the solid concealment layer 14b is a uniform pattern that covers the confidential data 12 as shown in FIG.

  FIG. 4 is an image view that is seen through when the scratch printed material 100 according to the first embodiment and the conventional scratch printed material 300 are respectively held over the backlight.

  FIG. 4A shows a shadow that can be confirmed on the surface of the scratch printed product 300 when the conventional scratch printed product 300 is held over strong light from the back side. In the example of the scratch printed material 300 shown in FIG. 4A, the concealing layer 14 is overprinted four times by offset printing on the confidential data 12, but the confidential data 12 is seen through.

  FIG. 4B shows a shadow that can be confirmed on the surface of the scratch printed material 100 when the scratch printed material 100 is held over strong light under the same conditions as in FIG. In the example of the scratch print 100 shown in FIG. 4B, the dummy concealment layer 14a is printed once on the same confidential data 12 as in FIG. 4A by offset printing under the same conditions as in FIG. Although the solid concealment layer 14b is overprinted three times, the confidential data 12 cannot be determined. The layer structure may be overcoated with the solid hiding layer 14b, the dummy hiding layer 14a, and the solid hiding layer 14b on the release layer.

  In the case of the conventional scratch printed material 300, since the film thickness of the concealing layer 14 is uniform, the light transmission when strong light is applied from the back surface becomes uniform, and the confidential data 12 can be identified. On the other hand, in the case of the scratch printed material 100, the dummy concealment layer 14a makes the light transmission non-uniform and makes it difficult to identify the confidential data 12.
