Description

  The present invention relates to a variable information printed matter such as a scratch lot, and in particular, has an effect of preventing forgery / forgery that is extremely difficult to falsify game parts and numbers, and improves design and adds game characteristics. Furthermore, the present invention relates to a variable information printed material that can machine-read variable information.

  As is known for scratch lots, etc., information (variable information) such as letters and symbols is printed on a substrate such as paper or plastic, and an opaque printing ink such as silver ink for screen printing is used on the printed information. There is known a printed matter in which a concealing layer is formed and a portion on which information (variable information) is printed is concealed. The printed material is rubbed with a coin or the like to peel off the concealing layer and display printed information (variable information) such as characters and symbols in the lower layer, thereby serving as a lottery.

  In such a scratch lottery ticket falsification, all or a part of the variable information (for example, characters such as 1st, Atari, etc.) of other tickets are cut out and pasted on the ticket to be falsified to be falsified as a winning ticket. There are many cases. As a measure for preventing tampering by cutting and pasting, a method is generally used in which a coloring pattern or the like is provided by printing on the background of variable information so that tampering by cutting and pasting is difficult. In consideration of the fact that variable information is read by a machine, the chromatic pattern at this time is applied with a thin red line, a halftone dot of each color, a light color, and the like. However, when continuous thin lines are used as the chromatic pattern, it is insufficient as a measure for preventing tampering.

  8 and 9 are explanatory diagrams showing an example of falsification of a winning ticket for a scratch lot. FIG. 9 is an explanatory diagram in the case where the winning ticket has been falsified successfully, and FIG. 9 is an explanatory diagram in the case where the winning ticket has not been falsified. 8 and 9, (a) shows a state of a ticket to be tampered before tampering, (b) shows a state during tampering, and (c) shows a state after tampering. For convenience of explanation, in FIG. 8 and FIG. 9, all of the concealing layer is in a peeled state.

  As shown in FIG. 8 (a), in the ticket (100) to be tampered, a thin line (101) continuous as a chromatic pattern is printed on the base material, and variable information represented by numbers on the base material is displayed at each position. It is printed on. The continuous thin line (101) is printed identically on all the tickets. Further, this example is an example in which a winning number is obtained when three consecutive numbers appear in the scratch lot as “123”, and the ticket (100) to be tampered with is a lost ticket.

  As shown in FIG. 8B, first, the variable information part (102) printed with “2” on the right side of the ticket (100) to be tampered is cut and discarded. Next, the variable information part (112) printed with “3” on the left side of the other ticket (110) is cut out, and the variable information part (102) of the ticket (100) to be tampered is cut off. to paste together. The falsified ticket (100 ′) obtained in this way is a series of three “123” as shown in FIG. 8C.

  The falsified ticket (100 ′) obtained in this way has three consecutive “123” s as shown in FIG. 8C, and is printed on the base material. The continuous thin line (101) and the thin line (111) of the pasted variable information section (112) are continuous at the boundary of the pasting, and this tampering has been successfully performed.

FIGS. 9A to 9B are explanatory diagrams when the winning ticket is not falsified successfully. In the ticket (120) to be tampered with, random thin lines (121) are printed as chromatic patterns in all number frames displaying the number of variable information represented by numbers on the base material. Further, this example is an example in which a winning number is obtained when three consecutive numbers appear in the scratch lot as “123”, and the ticket (120) to be tampered with is a lost ticket.

  As shown in FIG. 9A, first, the variable information part (122) printed with “2” on the right side of the ticket (120) to be tampered is cut and discarded. Next, another ticket on which “3” is printed at the same position as the variable information section (122) is selected, and variable information on which “3” on the left side of the selected other ticket (130) is printed. The portion (132) is cut out, and the variable information portion (122) of the ticket (120) to be tampered is pasted to the cut mark.

  The falsified ticket (120 ′) obtained in this way has a fine line (121) printed on the base material and a fine line (131) of the variable information section (132) pasted together. It becomes discontinuous at the boundary, and the authenticity of the ticket (120 ′) after falsification is known.

  In this way, as a measure to prevent tampering by cutting and pasting, even if a colored pattern is provided on the background of variable information by printing, a simple colored pattern can be printed by combining variable information at the same position on other tickets. Continuity will be reproduced. In addition, with a simple chromatic pattern, the chromatic pattern itself can be easily forged.

  As methods for compensating for such weak points of the chromatic pattern, for example, methods of adding a phosphor to the chromatic pattern, making the chromatic pattern complicated, or converting the chromatic pattern into micro characters have been proposed. With this method, it is difficult to easily carry out an authenticity evaluation of a ticket after falsification at a glance.

  The present invention has been made to solve the above-described problems, and has a forgery / forgery prevention effect that makes it very difficult to falsify variable information such as a game section and a number, and makes it possible to easily verify authenticity at a glance. The purpose is to provide variable information printed matter that can be used for scratch lottery, etc. that can improve the design that is constrained in Saimon, add game properties, and machine-readable variable information. .

To achieve the above objectives, ie

  That is, in the variable information printed matter of the present invention, the latent image line pattern in the image forming body layer is printed with a special ink such as a fluorescent ink, so that it cannot be visually recognized with ordinary sunlight or room light, thereby deteriorating the design. In addition, it is possible to machine-read variable information, and the design and game characteristics are further improved as a variable information printed matter such as a scratch lot.

  Further, in the variable information printed matter of the present invention, since the peeling varnish layer can be formed before the scratch concealment layer is formed, the scratch concealment layer can be easily scraped off and the variable information is broken. There is no end to it.

  Further, in the variable information printed matter of the present invention, since the ink receiving layer can be formed before the printing layer for displaying variable information is formed, the adhesion of the printing ink in the water-based inkjet printing is particularly good. This improves printing unevenness and does not hinder reading.

  As shown in FIG. 1, the variable information printed matter 10 of the present invention as an example is printed on a base material 1 with a special layer ink on which a latent image line pattern due to a lined moire pattern is floated. The image forming body layer 3, the ink receiving layer 4, and the printing layer 5 for displaying variable information are sequentially laminated, and a peeling varnish layer 6 and a scratch concealing layer 7 are sequentially laminated so as to cover the laminated body. Variable information printed matter. The image forming body layer 3 has two to several types of lines in which lines on the base layer 2 are arranged at different line angles at the same line pitch with a line ratio between the line part and the non-line part being 1: 1. A line pattern is formed, and a latent image line pattern formed by shifting the line phase by a half pitch with respect to the line pattern in one or several types of line pattern areas among the line patterns is provided. .

  As shown in FIG. 2, the variable information printed matter 20 of the present invention as another example is formed on the base material layer 1 by printing with a special ink in which a latent image line pattern by line moire is raised. The body layer 3, the patterned undercoat layer 2, the ink receiving layer 4, and the printing layer 5 for displaying variable information are sequentially laminated, and a peeling varnish layer 6 and a scratch concealing layer 7 are successively arranged so as to cover the laminated body. It is the variable information printed matter of the laminated structure. Then, the image forming body layer 3 is arranged in the same manner as described above on the base material 1 in which the lines with the same line pitch with 1: 1 line ratio between the line part and the non-line part are arranged at different line angles. Several types of line patterns are formed, and a latent image line pattern formed by shifting the line phase by a half pitch with respect to the line pattern within one to several types of line pattern areas of the line patterns. I have.

  As a base material which comprises the base material layer 1 in this invention, paper, a synthetic paper, a plastic sheet, or it can use individually or in combination.

  In addition, when the substrate is composed of a plastic sheet, a sheet of polyamide (nylon), cellulose diacetate, cellulose triacetate, polystyrene, polyethylene, polypropylene, polyester (polyethylene terephthalate, etc.), polyimide, polycarbonate, or other resin is used. Can be used.

  In the present invention, the image forming body layer 3 formed by printing with the special ink in which the latent image pattern due to the line moiré floats is displayed. The body is formed with two or several types of line patterns on the base layer, in which lines with the same line pitch of 1: 1 line ratio between the line part and the non-line part are arranged at different line angle. , Characterized in that it has a latent image line pattern formed by shifting the line phase by a half pitch with respect to the line pattern in one or several types of line pattern areas of the line pattern, Visualization line sheets in which a line pattern for visualization having the same line ratio and the same line pitch as the line pattern is formed on a transparent film on the two or several types of line patterns are mutually connected. Corner There polymerized to match, when irradiated with ultraviolet light, each parallel line angles formed to the corresponding line pattern region a latent image line pattern is visualized.

  The technique disclosed in Japanese Patent Application Laid-Open No. 2001-213042 can be applied to the image forming body on which the latent image line pattern by the line moire constituting the image forming body layer 3 in the present invention is formed. Hereinafter, an image forming body to which “line moiré” is applied will be briefly described.

  An image forming body to which the conventional “line moiré” is applied has a structure as shown in FIGS. 10A to 10D and FIG. 11, and image formation to which the conventional “line moiré” is applied. Since the body has a relatively simple pattern, it has a low effect as an anti-counterfeiting measure. The image forming body to which the “line moire” according to the present invention is applied can be easily performed at a glance as shown in FIGS. 3 (a) to 3 (e).

  First, a printed matter using the conventional “line moire” will be described. FIG. 10A shows a normal print image 31 without a line pattern formed on the paper 30 by printing, and FIG. A line pattern 40 composed of parallel straight lines in which a large number of parallel straight lines having the same line width printed and formed on the paper 30 are arranged at the same pitch (equal interval) as the line width, FIG. 30 is a printed matter A in which the normal print image 31 and the line pattern 40 are overprinted.

  The line pattern 40 shown in FIG. 10B is provided with a latent image line pattern 40a (for example, a heart-shaped pattern portion as shown), and the latent image line pattern 40a in the line pattern 40 is shown in FIG. As shown in the enlarged view of the M portion in (d), the pitch phase of each parallel straight line (line) of the inner region and the outer region of the latent image line pattern 40a is changed to a boundary equivalent part (latent image line pattern 40a of both regions). Are formed by shifting by a half pitch along the contour line.

  The parallel straight lines (line lines) constituting the line pattern 40 have a fine line width that is thin enough not to interfere with the print design of the normal print image 31, and in the inner region of the line pattern 40. Since the lines of the formed latent image line pattern 40a are only shifted in pitch phase with respect to the lines in the outer region, and the lines are fine, the latent image line pattern 40a is visually Specifically, nothing is visually observed as an image (in appearance), and only the normal print image 31 and the line pattern 40 are observed on the printed matter A.

  As shown in FIG. 4, a line sheet B in which a line pattern 60 having the same line width and pitch as the line pattern 40 of the print A is formed on the surface of the transparent film 50 on the print A (FIG. 10C). When the lines are overlapped in parallel, the lines in the inner area and the outer area of the latent image pattern portion 3a of the line pattern 40 formed on the printed matter A are shifted by half a pitch. The lines overlap each other on each line shifted by a half pitch between the inner area and the outer area of the latent image line pattern 40a of the line pattern 40 formed on the printed matter A (the lines of the line pattern 40). And a part that does not overlap (a line of the line pattern 40 is not hidden) occurs.

  As a result, for example, the line of the line pattern 40 that does not overlap with the line of the line pattern 60 changes the line pattern 40 in the area of the latent image line pattern 40a (for example, a heart-shaped pattern portion as shown). If the line is a line, the line is visually observed through a transparent portion (transparent line; white line) between each line (opaque line; black line) of the line pattern 60 and is a latent image. The line pattern 40a is visualized and observed as a positive image.

  On the other hand, for example, the line of the line pattern 40 that does not overlap the line of the line pattern 60 constitutes the line pattern 40 outside the latent image line pattern 40a (for example, a heart-shaped pattern portion as shown). If the line is a line, the line is observed through the transparent portion (transparent line; white line) between each line (opaque line; black line) of the line pattern 60 and the latent image The line pattern 40a is visualized and observed as a negative image.

On the other hand, in the image forming body using the “line moiré” in the present invention, as an example, the visualized line sheet is superimposed on the line pattern on which the latent image line pattern is formed, and the overlapping is performed. When the surface is rotated, it is possible to easily determine the authenticity of the printed matter because it has a multi-order change function that visualizes different images according to the latent image pattern one after another.

  As shown in FIG. 3A, the image forming body A according to the present invention has a line ratio of line portions and non-line portions on the underlayer 30 of 1: 1, and a line pattern 40 having the same line pitch. The line pattern 40 is composed of two to several types of line pattern areas formed at different line angles.

  Each pattern region formed at different line angles of the line pattern 40 is provided with a latent image pattern by a latent image line pattern 40a formed by shifting the line phase by a half pitch.

  On the line pattern 40 of the image forming body A in the present invention, as shown in FIG. 3B, the same line ratio as the line pattern 40 (the line ratio between the line part and the non-line part is 1: The line sheet B on which the line pattern 60 having the same line pitch as in 1) is formed on the transparent substrate 50 is superposed with its line direction aligned.

  3 (c) to 3 (d), the line sheet B is superposed on the line pattern 40 of the image forming body A, and each line image is aligned with the line angle on the one or several kinds of latent image line patterns. This shows a state in which the latent image pattern formed by the latent image line pattern 40a corresponding to the angle is visualized when polymerization is performed at an angle (parallel).

  In FIG. 3C, the visualized line sheet B is superimposed on the line pattern 40, and the line of the line pattern 60 is set in the horizontal direction (angle 0 °), for example, with the letter “T”. By superposing and aligning with the horizontal line direction (angle 0 °) of the latent image line pattern 40a, the letter “T” is visualized through the visualized line sheet B.

  In FIG. 3D, the visualized line sheet B is overlaid on the line pattern 40, and the line of the line pattern 60 is inclined in the direction of 45 ° so that, for example, the latent character “P” is hidden. By superimposing in alignment with the direction of the line inclined to 45 ° of the image line pattern 40a, the letter “P” is visualized through the visualized line B.

  As a result, latent image line patterns (for example, latent image patterns of characters of T, O, and P) formed in each line pattern region corresponding to each line angle are converted into visualized line sheets, respectively. By adjusting the angle, the image is visualized as a visualized image (for example, characters of T, O, and P). For example, the line of the line pattern of the image forming body that does not overlap the line of the line pattern of the visualized line sheet may be a line constituting the line pattern in the latent image line pattern area. For example, the lines are observed through the transparent part (transparent line; non-line part) between each line (opaque line; black line; line part) of the line pattern, and the latent image line. The pattern is visualized and observed as a positive image.

  On the other hand, for example, the lines of the line pattern of the image forming body that do not overlap with the lines of the line pattern of the visualized line sheet constitute the line pattern outside the latent image line pattern area. If this is the case, the line is visually observed through the transparent part (transparent line; non-line part) between each line (opaque line; black line; line part) of the line pattern. The line pattern is visualized and observed as a negative image.

For the printing of the latent image line pattern formed on the image forming body layer 3 in the present invention described above, the latent image line pattern is arbitrarily shifted using, for example, a plate having a total of 20 vertical 4 × 5 horizontal surfaces. Innumerable different patterns can be formed by printing while printing. For example, if the printing is shifted by 1 degree per rotation, there are 360 different patterns, and even if 1000 sheets are printed, only 3 printed materials having the same latent image line pattern are generated. . Further, by adding control for shifting printing, the latent image line pattern can be broadened. If the latent image line pattern is printed by ink jet printing without using a plate, unlimited different latent image line patterns can be formed. When an ink jet printing method is applied, it is preferable to provide an ink receiving layer described later on the base.

  The print density of the latent image line pattern in the present invention has a PCS value (Point Contrast Signal value; relative reflectance; a value indicating contrast) represented by the following formula (1) of 0.2 or less (A filter). It is desirable. When the PCS value exceeds 0.2, there is a concern that some printing is performed with the naked eye.

PCS value = (Line non-linear part reflectance-line line part reflectivity) / line non-line part reflectivity
(1)
In the line pattern formation region in the variable information printed material of the present invention, a normal print image or color by a completely independent design or the like may be formed as a background image or background color. However, in consideration of the reproducibility and visualization of the latent image pattern by the latent image line pattern, it is better to avoid the color approximate to the color tone adopted for the latent image pattern because it may cause camouflage. In addition, a normal print image and coloring by a completely independent design may be formed in an area other than the line pattern formation area. Thus, since the image with gradation is provided by printing, there are no restrictions on the design as in the case of the color pattern, and the design is beautiful. In addition, since the image having gradation is provided by printing as described above, game characteristics are added to the variable information printed matter.

  The special ink used for printing the latent image line pattern to be formed on the image forming body layer 3 in the present invention is irradiation with black light (visible light that emits visible light when hit with a fluorescent material). A fluorescent ink containing a fluorescent substance that develops color is used. As the fluorescent material, various inorganic fluorescent materials may be used, but fluorescent whitening agents and the like are also used from the viewpoint of cost.

  As these fluorescent substances, fluorescent dyes and fluorescent pigments are used. Specifically, as fluorescent dyes, fluorescent dyes such as fluorescein, coumarin, oxazole, pyrazoline, thiadiazole, spiropyran, pyrenesulfonic acid, benzimidazole, diaminostilbene, etc. Both organic and inorganic fluorescent pigments can be used. Specific examples of organic fluorescent pigments include fluorescein, eosin, rhodamine 6G, rhodamine B, basic yellow HG and the like on resins such as polyvinyl chloride resin, alkyd resin, polymethacrylate resin, urea resin, and melamine resin. Examples include those obtained by uniformly dissolving and pulverizing a dye.

Specific examples of inorganic fluorescent pigments include zinc sulfide activated with copper, silver, manganese, etc., zinc silicate activated with manganese, zinc cadmium sulfide activated with silver, copper, etc., bismuth, etc. Activated by calcium sulfide, strontium sulfide activated by samarium, cerium, etc., calcium tungstate activated by lead, etc., Sr (PO ₄ ) ₃ Cl activated by europium, etc., Zn ₂ activated by manganese, etc. Examples thereof include Y ₂ O ₂ S activated with GeO ₂ , europium and the like, Y ₂ O ₃ activated with europium and the like. In addition, a sensitizer such as anthraquinone or acetophenone can be used in combination with these as appropriate.

  The fluorescent ink is not limited to printing for offset, and the latent image line pattern of the image forming body layer can be formed using, for example, an organic fluorescent pigment as fluorescent ink for letterpress printing, gravure printing, or flexographic printing.

The underlayer 2 with a pattern according to the present invention is provided with a random pattern by printing.

  As the printing layer 5 for displaying variable information in the present invention, an ink suitable for each of ordinary printing methods such as ordinary offset printing, gravure printing, flexographic printing, various transfer printing, or ink jet printing without using a plate is used. Can be used. Also, there is no special limitation on the design and the like, and variable information such as numbers, symbols, and characters is printed.

  In particular, in the case of an aqueous inkjet printing method, an ink receiving layer is provided. The ink receiving layer 22 in the present invention is a composition mainly composed of a pigment and a binder satisfying characteristics such as color reproducibility and high definition with respect to an ink containing a dye component used in a commercially available ink jet recording apparatus. It is a layer which fulfill | performs the function which adheres the ink which consists of.

  The pigment used for the ink receiving layer 4 is not particularly limited, and one or more known pigments can be used. For example, light calcium carbonate, heavy calcium carbonate, kaolin, talc, calcium sulfate, barium sulfate, titanium dioxide, zinc oxide, chisan white, zinc carbonate, magnesium carbonate, aluminum silicate, calcium silicate, magnesium silicate, synthetic amorphous silica , Colloidal silica, colloidal alumina, pseudoboehmite, aluminum hydroxide, alumina, lithopone, zeolite, hydrohalosite, magnesium hydroxide and other inorganic pigments, acrylic plastic pigment, styrene plastic pigment, microcapsule, urea resin, melamine resin And organic pigments such as Among these, porous inorganic pigments are preferable, and examples include porous synthetic amorphous silica, porous magnesium carbonate, and porous alumina. Particularly, porous synthetic amorphous silica having a large pore volume is preferable in terms of cost. .

  The binder used for the ink receiving layer 4 is not particularly limited, and one or more known binders can be used. For example, synthetic products include polyvinyl alcohol, silanol modified polyvinyl alcohol, partially acetalized polyvinyl alcohol, allyl modified polyvinyl alcohol, modified polyvinyl alcohol such as polyvinyl methyl ether, polyvinyl ethyl ether, and polyvinyl isobutyl ether, polyacrylate, Acrylic ester partial saponification products, polymethacrylic acid salts, polyacrylic acid derivatives such as polyacrylamide and polymethacrylic acid derivatives, polyethylene glycol, polyethylene oxide, polyvinyl pyrrolidone, vinyl pyrrolidone vinyl acetate copolymer, styrene butadiene copolymer , Nitrile butadiene copolymer, styrene acrylate copolymer, styrene maleic acid copolymer, styrene crotonic acid Polymers, vinyl containing copolymer chloride. Examples of natural products include proteins such as gelatin, starches such as potato, algae such as agar, plant mucilage such as mannan, and microbial mucilage such as glucan.

  The release varnish layer 6 in the present invention is preferably provided in the case where the peelability is poor when the concealing layer is scraped off and the variable information is broken. The material of the release varnish layer is not particularly limited as long as it is transparent, can read variable information through this layer, can visually recognize prints, and has a toughness that cannot be scraped off even when rubbed with a coin. It is not a thing. For example, an ultraviolet or electron beam curable acrylic ink or the like to which a lubricant such as silicon is added is used.

  The scratch concealment layer 7 in the present invention is a layer having a property of concealing the lower layer and being able to be scraped off relatively easily by rubbing with a coin edge or the like. A high pigment is a relatively large amount dispersed in a binder resin, and if necessary, a dye or a normal pigment may be blended for the purpose of coloring.

  Examples of highly concealing pigments constituting the scratch concealing layer 7 include metal powders such as aluminum powder, brass powder, or copper powder, calcium carbonate, zinc oxide, alumina, titanium dioxide, silica, barium sulfate, talc, kaolin, Clay, carbon black, resin powder or the like can be used.

  Further, as the binder resin constituting the scratch concealment layer 7, the above-mentioned pigment having high concealability is retained and one having good adhesion to the seal substrate is selected and used. For example, natural rubber or hydrochloric acid rubber Rubber-based natural resins such as polybutadiene, styrene / butadiene copolymer, acrylonitrile / butadiene copolymer, polyisoprene, polychloroprene, acrylic, vinyl chloride, or vinyl chloride / vinyl acetate copolymer.

  In order to laminate the scratch concealing layer 7, the above-described pigment having a high concealability, a binder resin, a solvent, and the like are mixed and dispersed to form a scratch layer forming ink composition or coating composition, Although printing or coating can be performed by a known printing method or coating method, generally, printing is performed by silk screen printing.

  The scratch concealment layer 7 is preferably one that can be easily removed when a certain level of force is applied. However, the scratch concealment layer 7 is a function that should conceal the lower layer under normal storage conditions and handling. Moreover, since it is not preferable, a protective layer may be formed on the scratch concealment layer 7.

  The protective layer can be formed by applying an appropriate resin solution. Examples of the resin include phenol resin, xylene resin, urea resin, melamine resin, ketone resin, alkyd resin, polyamide resin, acrylic resin, polyvinyl chloride resin, A vinyl chloride / vinyl acetate copolymer resin, a polyvinyl acetate resin, a polyvinyl alcohol resin, a polyvinyl butyral resin, a polystyrene resin, an epoxy resin, or a polyurethane resin can be used.

  Since the variable information printed matter of the present invention has the above-described configuration, even if an attempt is made to falsify the variable information printed matter of the present invention, it is possible to easily verify the authenticity at a glance. That is, FIGS. 4A to 4C are explanatory diagrams when falsification of a scratch ticket as an example of the variable information printed matter of the present invention is attempted. For convenience of explanation, in FIG. 4, all the concealing layers are in a peeled state. In the scratch lottery ticket (70) to be tampered with, random patterns (72) are printed in all the number frames displaying the number which is variable information on the base material. Further, a latent image line pattern (71) is printed on the image forming body layer using a special ink such as a fluorescent ink. Since the latent image line pattern (71) is printed using special ink such as fluorescent ink, it cannot be visually recognized by sunlight or room light. This example is an example of winning when the number of the scratch lot ticket is “123” in succession, and the scratch ticket (70) to be falsified is a lost ticket.

  In FIG. 4, (a) shows a state of a scratch ticket to be tampered before tampering, (b) shows a state during tampering, and (c) shows a state after tampering.

  As shown in FIG. 4 (a), first, the variable information part (73) on which “2” on the right side of the ticket of the scratch ticket (70) to be tampered is printed is cut out and discarded. Next, another ticket printed with “3” is selected in the variable information section, and the variable information section (83) printed with “3” on the left side of the selected other scratch ticket (80). The variable information part (73) of the scratch lottery ticket (70) to be tampered with is attached to the cut mark.

When the surface of the scratch ticket (70 ') after falsification obtained in this way is irradiated with ultraviolet light using black light or the like, as shown in FIG. 5 (c), a special ink such as fluorescent ink for the image forming body layer is used. The latent image line pattern (71) printed in (1) can only be visually observed as a random pattern (71 ') that is simply colored and cannot be discriminated.

  FIG. 6 is a plan view of the visualized line sheet 90 in which a visualization line pattern 60 for visualizing the latent image line pattern printed on the image forming body layer in the present invention is formed on the transparent film 50. FIG. As shown in FIG. 7A, when the visualized line sheet 90 is superimposed on the surface of the scratch ticket (70) to be tampered with and is irradiated with ultraviolet rays by a black light or the like, a latent image line is obtained. The pattern is visualized and the character pattern (70 ″) is visually observed. Similarly, as shown in FIG. 7 (b), it is superimposed on the surface of the scratched ticket (80) being tampered with, and when exposed to ultraviolet light such as black light, the latent image line pattern is visualized, The character pattern (70 ″) is visually observed. Further, as shown in FIG. 7 (c), when aligned with the surface of the scratched ticket (70 ') after falsification and irradiated with ultraviolet rays by black light or the like, the latent image line pattern is visualized and characters The pattern (70 ″) is visible.

  The scratch ticket (70 ') after falsification obtained in this way is composed of the character pattern (71') obtained by visualizing the latent image line pattern printed on the base material and the variable information pasted together. The character pattern (81 ′) obtained by visualizing the latent image line pattern of the part (83) becomes discontinuous at the boundary portion of the pasting, and the authenticity of the tampered ticket (71 ′) at first glance It is easy to understand.

  In the variable information printed matter of the present invention, even if a printed pattern is provided on the background of the conventional variable information by printing, the simple printed pattern can be combined with variable information at the same position on other tickets to continue the printed pattern. Will be reproduced. In addition, with a simple chromatic pattern, the chromatic pattern itself can be easily forged. As a method of compensating for such weak points of the chromatic pattern, for example, even if a method of adding a phosphor to the chromatic pattern, making the chromatic pattern complicated, or converting the chromatic pattern into micro characters, variable information can be used. In the method of providing a scented pattern or the like by printing on the background of the paper, it is possible to avoid the problem that it is difficult to easily perform the authenticity evaluation of the ticket after the alteration.

  As described above, the variable information printed matter of the present invention is provided with the image forming body layer printed with the special ink on which the latent image line pattern due to the line moiré is lifted, so that the latent image line pattern is provided on the variable information printed matter. It is extremely difficult to falsify even if trying to falsify by overlaying the visualized line sheet formed on the transparent film for visualizing the image, and irradiating with ultraviolet light by black light etc. The authenticity can be easily identified at first glance, and the variable information printed matter can be provided which improves the design that is restricted by the coloring pattern and the like, adds game characteristics, and is capable of machine reading of variable information.

  Further, in the variable information printed matter of the present invention, the image forming body layer is printed with special ink, so that it cannot be visually recognized by ordinary sunlight or room light, so that the design is not impaired, and the variable information can be read mechanically. This is possible, and the design and game characteristics are further improved as a variable information printed matter used for scratch lots and the like. Further, in the variable information printed matter of the present invention, since the peeling varnish layer can be formed before forming the concealing layer, the concealing layer can be easily scraped off and the variable information is broken. There is nothing. Further, in the variable information printed matter of the present invention, since the ink receiving layer can be formed before forming the print layer for displaying variable information in the variable information printed matter, printing in water-based inkjet printing in particular. Ink adhesion is improved, printing unevenness, etc. occur, and reading is not hindered.
