Description

  The present invention relates to a printed matter with a scratch concealment layer represented by an instant ticket, and more specifically, when scratch-off (scratching off) the scratch concealment layer, individual information representing a win or the like is scraped off, The present invention relates to a printed matter with a scratch concealment layer on which anti-counterfeiting measures such as tampering are prevented.

  Conventionally, for example, in an instant ticket or a game card, in order to conceal individual information such as “winning”, “disappearance” or grade, and a picture or symbol corresponding to them, concealment and scratch-off (scratch) The individual information is concealed with ink having ease of removal), and the customer or the sales office, etc., scratches off the scratch concealment layer with coins, nails, etc., and the individual information is visually recognized or read by a machine. Accompanying printed materials are known and used in various fields.

  As the printed matter with the scratch concealing layer, for example, as shown in the laminated sectional view of FIG. 6, individual information (12) such as a pattern, characters, numbers, etc. is printed on a base sheet (10) made of paper or the like. A transparent easily peelable layer (32) made of a transparent release varnish or the like is formed so as to cover the individual information (12), and a scratch concealing layer containing aluminum powder or the like on the transparent easily peelable layer (32) ( 34) and a printed matter (2) with a scratch concealment layer provided with a transparent protective layer (17) for protecting the scratch concealment layer (34).

  The customer who purchased the printed matter with the scratch concealment layer (2) or the sales office, etc., scratches off the scratch concealment layer (34) with a coin, a nail, or a special scratch peeling device. Individual information (12) such as “win”, “displacement”, 1st, 2nd, etc., or a corresponding pattern, symbol, etc. is visually observed through the transparent easily peelable layer (32), or the individual information (12) is In the case where the contents such as a bar code or a security code cannot be seen by visual recognition, it can be recognized by reading with a dedicated OCR (optical character symbol reader).

  However, in the conventional printed matter with a scratch concealment layer, the scratch concealment layer (34) on which a forgery prevention measure is applied with a coin or a nail is scratched off, for example, as shown in FIG. A lottery with a scratch concealment layer (not shown) selected as individual information (12) in order of “1”, “2”, and “3” in each print frame (40) In the case of the printed matter (3), the individual information (12) as shown in FIG. 7 (b) is the right end of the printed matter (3) with a lottery that is an outlier in the order of “1”, “2”, “2”. Cut out including “2” in the print frame (40), and the individual information (12) as shown in FIG. 7 (c) is an extra ticket arranged in the order of “3”, “2”, “2”. Cut out the “3” in the print frame (40) at the left end of a certain printed matter (3) The printed information with a lottery (3) shown in (b) is pasted into the rightmost printing frame (40), and the individual information (12) as shown in FIG. 7 (a) is “1”, “2”. When “3” is arranged in order, there is a large problem that the printed matter with lottery (3), which is a winning ticket to be won, is falsified.

  For example, as shown in FIG. 8A, “1”, “2”, and “3” are printed as individual information (12) as one measure for preventing such forgery due to tampering. Within the three print frames (40), the variable information printed matter (4) is provided with a forgery prevention measure in which a fine pattern (13) made up of random patterns is printed under the individual information (12). Is.

  If the variable information printed matter (4) is to be tampered with, forgery prevention is won when "1", "2", and "3" are arranged in order as individual information (12) in the three print frames (40), respectively. In the case of the variable information printed matter (3) to which the measure is applied, forgery prevention in which the individual information (12) as shown in FIG. 8B is a slip-off ticket arranged in the order of “1”, “2”, “2” The variable information printed matter (4) to which the measure is applied is cut out including “2” in the print frame (40) at the right end and the fine pattern (13) around it, as shown in FIG. 8 (c). “3” in the print frame (40) at the left end of the variable information printed matter (4) on which the forgery prevention measure is applied, where the individual information (12) is a slip-off ticket arranged in the order of “3”, “2”, “2”. ”And the surrounding striped pattern (13) were cut out, and the counterfeit prevention measures, which is a slip-off ticket shown in FIG. The winning information print (4) is pasted into the print frame (40) at the right end, and the individual information (12) as shown in FIG. 8 (a) is arranged in order of “1”, “2”, “3”. When the variable information printed matter (4) to which the counterfeit prevention measure which is a ticket is applied becomes the variable information printed matter (4) which is supposed to be the winning ticket shown in FIG. 8B is cut out from the left end of FIG. 8C in the right end printing frame (40), and the thin pattern (13) around the individual information (12) composed of “3” and the outside are pasted together. The thin strip pattern (13) has no continuity and is discontinuous, and the variable information printed matter (4) on which the forgery prevention measure determined to be forgery by such a discontinuous strip pattern (13) is applied. ).

  However, even in the variable information printed matter (4) in which the anti-counterfeiting measure in which the fine pattern (13) is provided in the print frame (40), in the case of a simple fine pattern, it is the same or extremely similar. By cutting and pasting the individual information (12) to which the fine pattern (13) has been applied, it is possible to make the fine pattern (13) have continuity. There is a risk of tampering such as cutting and replacing the entire printed frame with the pattern, and there is a problem that it is not a complete anti-counterfeiting measure.

  The present invention solves the problems of the prior art, and the problem is to scratch off the scratch concealment layer that conceals the individual information representing the failure, etc., and intentionally cut and falsify the individual information. It is an object of the present invention to provide a printed matter with a scratch concealment layer on which anti-counterfeiting measures are taken without fear of being lost.

  In order to achieve the above-mentioned problems in the present invention, in the invention of claim 1, in the printed matter with a scratch concealment layer in which the individual information representing the hit or the like is covered with the scratch concealment layer on the base material sheet, The information is formed by a plurality of lines composed of line patterns extending in the same direction at the same pitch, and the phases of the line patterns of the lines are shifted by 1 / plurality, on the plurality of lines. A line composed of an image line portion and a non-image line portion extending in the same direction at the same pitch as the plurality of image lines via a transparent varnish layer having a predetermined thickness is applied to the image line portion and the non-image line portion. The printed matter with a scratch concealment layer is provided with a forgery prevention measure characterized in that the ratio is a plurality of 1: 1.

  According to a second aspect of the present invention, the thickness of the transparent varnish layer depends on the width of the line-drawn portion and the non-image-line portion of the line, and is 0.5 to 3 times the non-image-line portion. A printed matter with a scratch concealment layer to which the forgery prevention measure according to claim 1 is applied.

  Further, in the invention of claim 3, forgery of any one of claims 1 to 2, wherein any one of the plurality of image lines constituting the individual information is formed of fluorescent ink. This is a printed matter with a scratch concealment layer to which a preventive measure has been applied.

  Since this invention is the above structure, there exist the following effects.

  That is, according to the first aspect of the present invention, in the printed material with the scratch concealment layer in which the individual information representing the hit or the like is covered with the scratch concealment layer on the base sheet, the individual information is in the same direction at the same pitch. A transparent varnish formed of a plurality of lines composed of extending line patterns, wherein the line patterns of the lines are shifted by 1 / plurality and have a predetermined thickness on the plurality of lines. A line consisting of an image line portion and a non-image line portion extending in the same direction at the same pitch as the plurality of image lines is provided through a layer, and a ratio of the image line portion and the non-image line portion is a plurality of 1: 1. When the scratch concealment layer is scratched off and the viewing angle is changed from the direction intersecting the extending direction of the line pattern of each image line, a plurality of image lines (information) are observed. Compared to conventional (single) plane information Security and authenticity determination function is being applied may be a scratch concealing layer provided prints anti-counterfeit measures have been subjected to allowed to be improved design.

  Moreover, according to the invention which concerns on the said Claim 2, by setting the thickness of the said transparent varnish layer to 0.5 to 3 times the said non-image line part of the line which consists of an image line part and a non-image line part, Even if the viewing angle (information) due to a change in viewing angle is easily visible as a sharp image, and the thickness of this transparent varnish layer is less than 0.5 times the non-drawing portion of the line, If the image line is cut off more than 3 times, it is not preferable because a transparent varnish layer having a uniform thickness cannot be obtained by printing or coating.

  Furthermore, according to the invention according to the third aspect, any one of the plurality of image lines constituting the individual information is formed of fluorescent ink that is difficult to visually recognize under visible light. Since it is observed with a dedicated black light for the determination of authenticity, it is possible to obtain a printed matter with a scratch concealment layer on which a forgery prevention measure that makes forgery more difficult is applied.

  Therefore, the present invention is a printed matter with a scratch concealment layer represented by an instant ticket, especially when the scratch concealment layer is scratched off (scratched off), and individual information representing the hit or the like is scraped off or falsification such as tampering is performed. As a printed matter with a scratch concealment layer to which an anti-counterfeit measure is not applied, an excellent practical effect is exhibited.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  In the present invention, for example, as shown in the side cross-sectional view of FIG. 1, individual information (12) representing winning or the like is applied on the base sheet (10) so as to cover the individual information (12). A printed matter with a scratch concealment layer such as an instant ticket in which a scratch concealment layer (34) is formed via a transparent easy release layer (32). In particular, forgery prevention measures have been taken on this individual information (12). The present invention relates to a printed matter (1) with a scratch concealment layer.

  As an anti-counterfeiting measure, as shown in FIG. 1, the line (14) extending in the same direction as the line pattern and having the same pitch on the individual information (12) having a line pattern is formed on the transparent varnish layer (16 ), And one of the individual information (14) emerges from the gap (non-image portion) of the line (14) and is visually recognized. This is an application of the method.

Hereinafter, the present invention will be described in more detail. In the invention according to claim 1, the individual information (12) shown in FIG. 1 is, for example, “1” having a line pattern as shown in FIG. 2 (a). Etc. "and the phase of the" long "line pattern extending in the same direction as this line pattern and having the same pitch are formed by being shifted by 1/2 pitch.

  In FIG. 2A, both “1st grade” and “this” are bordered for ease of explanation, but in actuality, for example, as shown in the enlarged view of FIG. In other words, the line width (W) and the pitch (P) are formed as a single line pattern having a line width (W) of about 1: 2 to 3.

  Further, as the individual information (12), “1 etc.” composed of a line pattern and “this” formed with a ½ pitch shift from this line pattern are passed through a transparent varnish layer (14). For example, as shown in FIG. 3, the line information extends in the same direction as the “1 etc.” and “this” line pattern constituting the individual information, has the same pitch (P), and has a line width of ½ pitch. (W), that is, a line (14) in which the image area (14a) and the non-image area (14b) are 1: 1 is formed.

  Scratch concealment of printed matter with scratch concealment layer (1) with anti-counterfeiting measures in which "1 etc." and "one" as two individual information (12) are formed as described above (1) When the layer (34) is scratched off and observed from the viewpoint A (A), for example, as shown in FIG. 4A, the transparent line (32) passes through the transparent line (14) and the non-image of the line (14). From the line part (14b), one of the two pieces of individual information (12a, 12b) shown in FIG. 4 (a) is changed to “the” as the individual information (12a) as shown in FIG. 4 (b). Letters are observed.

  Further, when the viewing angle is changed, for example, as shown in FIG. 4A, when viewed from the viewpoint B (B), the transparent line (32) passes through the non-image portion ( 14b), one of the two pieces of individual information (12a, 12b) shown in FIG. 4 (a) is converted into two pieces of individual information (12a, 12b) shown in FIG. “1 etc.” as other individual information (12b) in 12b) is observed.

  The two pieces of individual information (12a, 12b) shown in FIG. 4 (a) are “to” and “1 etc.”. For example, as shown in FIG. 5 (a), instead of one piece of individual information. The sheet number (15) can also be used. For example, the scratch concealment layer of the printed matter with the scratch concealment layer (1) to which the forgery prevention measures shown in FIG. When observed, through the transparent easily peelable layer, from the non-image part (14b) of the line (14), as shown in FIG. When observed from the viewpoint B (B), as shown in FIG. 5 (c), a part (15a) of the face number is “789” from the non-image portion (14b) of the line (14). ”And the individual information and the ticket number (15) are matched in this way, Kyuriti properties may be enhanced.

  Although not shown, for example, a background pattern or the like may be inserted as a background instead of “one” which is individual information. In the case of this background pattern, it is not necessary to apply a line pattern, and a low-density light color is used. I just need it.

  Furthermore, the individual information (12) can also be constituted by three pieces of information (image lines) having a line pattern. At this time, the phase of the line pattern forming each individual information (image line) is shifted by 1/3 pitch. One of the three pieces of information (image line) can be used as a background portion made of a background pattern or the like.

  The number of lines constituting the individual information (12) is plural in the claims. However, if the number of lines is limited to three including the background, and more than that, each line can be observed through the line (14). The information (image line) is cut off, which is undesirable from the viewpoint of design.

Moreover, the invention according to claim 2 is, for example, as shown in FIG.
The thickness (D) of 6) depends on the width of the image line part (14a) and the non-image line part (14b) of the line (14), and is 0.5 of the non-image line part (14b). -3 times, preferably 1-2 times.

  If the thickness (D) of the transparent varnish layer (16) is less than 0.5 times the non-image portion (14b) of the line (14), for example, the viewpoint A (A) shown in FIG. And the angle of the viewpoint B (B), that is, the observation angle needs to be increased considerably, and even if the angle is increased, other image lines (12b with respect to 12a) may not be observed. If it exceeds 3 times, it is difficult to obtain a transparent varnish layer (16) having a uniform thickness by printing or coating. When the width of the non-image portion (14b) of the line (14) is preferably set to 1 to 2 times, each sharp image line (12a, 12b) is observed.

  Furthermore, in the invention according to claim 2, for example, “this” in the individual information (12) composed of “this” and “1 etc.” shown in FIG. It is made of fluorescent ink that cannot.

  As described above, the individual information (12) that is formed with the fluorescent ink has a scratch-off layer after being scratched off. For example, as shown in FIG. At view point B (B), information (12b) of “1st magnitude” is observed from the gap of the line (14), that is, from the non-image portion (14b). Will not be visible.

  When the black light emitting ultraviolet rays is irradiated from the viewpoint A (A) with the changed viewing angle, the “to” image line (12a) is observed to emerge with fluorescence, and from the viewpoint B (B) with the changed viewing angle. Will not be visible.
