Description

  The present invention is based on a copying machine or a PC-related device in the field of valuable printed materials such as banknotes, passports, securities, identification cards, cards, and passports, which are security printed materials that require anti-counterfeiting effects. The present invention relates to a relief printing material that is difficult to copy or reproduce.

  Counterfeiting and anti-counterfeiting measures are important elements in valuable securities such as banknotes, stock certificates and bonds, various certificates and important documents. Therefore, the printed surface of the precious printed matter forms a pattern with extremely fine lines.

  As a method that has been used for a long time in measures for preventing counterfeiting and alteration of printed matter, there is a method of applying a collective pattern of characters with a character angle of 1 mm or less, called a minute character, to the printed matter.

  As an example, a technique for preventing forgery by applying a collective pattern with minute characters using a special typeface is disclosed (for example, see Patent Document 1).

  In addition, an engraving intaglio printed matter is disclosed in which minute characters corresponding to positive or negative are incorporated into the image line portion in the aggregate pattern by changing the image line depth (see, for example, Patent Document 2). .

  However, the techniques of Patent Document 1 and Patent Document 2 are useful techniques for preventing copying. However, due to recent developments in the resolution of copying machines and the development of PC-related equipment, special characters such as small characters and marginal characters are used. There is a possibility that the zone is also reproduced.

  SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems, and forms a special typeface by a copying machine and a PC-related device by forming at least one micro character having a minute marginal zone area in a relief printing image line. The present invention provides an anti-counterfeit printed matter capable of preventing the reproduction of minute characters and marginal zones.

The present invention has a printed image line group formed by arranging a plurality of first printed image lines on the base material in the form of numbers, characters and / or symbols having a first marginal zone,
The print image line group includes the first print image line including a second print image line forming information including a second marginal zone in the first print image line. This is an anti-counterfeit printed matter

  The present invention is the anti-counterfeit printed matter, wherein the first print image line and the second print image line are formed by a ring of a numbering machine.

  The anti-counterfeit printed matter of the present invention is a number having a fine marginal zone formed in a relief printing line having the shape of a number, character and / or symbol even when a PC-related device or a copying machine is used. Since the micro characters forming the shape of characters and / or symbols cannot be reproduced by a PC-related device and cannot be copied by a copying machine, the anti-counterfeiting effect is excellent.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments described below, and includes various other embodiments within the scope of the technical idea described in the scope of claims.

  FIG. 1 shows an anti-counterfeit printed matter (1) in the embodiment. The present embodiment is an example in which the print image group (3) is formed by letterpress printing and the first print image line (3a) is formed by numbers. The print image line group (3) is formed by arranging a plurality of first print image lines (3a) having the shape of numbers, characters and / or symbols. FIG. 1A is a front view of an anti-counterfeit printed matter (1). The anti-counterfeit printed matter (1) is a first printed image line (3a) having a number shape on a base material (2). A printed image line group (3) in which a plurality of images are arranged is formed. FIG. 1B is a partially enlarged view of the first print image line (3a) that forms the print image line group (3) of the anti-counterfeit printed matter (1). The first print image line (3a) has the second print image line (4) in the image line.

  The first printed image line (3a) only needs to be formed by letterpress printing, and may be in the form of not only numbers but also letters and / or symbols. The color of the first print image line (3a) is a color different from that of the substrate (2). The substrate (2) may be paper, plastic, metal, etc., as long as the printed image line group (3) can be formed, and the material thereof is not limited. In the present embodiment, a plurality of first print image lines (3a) are arranged to form a print image line group (3). It may also be formed by combining symbols and / or numbers, letters and / or symbols by known letterpress printing.

  FIG. 2 shows a first print image line (3a) and a second print image line (4). FIG. 2A is a partially enlarged view of the first print image line 3a, and FIG. 2B is a cross-sectional view taken along the line AA 'of the first print image line 3a. is there. As shown in FIG. 2 (a), the first printed image line (3a) is formed by letterpress printing, and therefore has a darker color and the same color as the first printed image line (3a) around the image line. It has a first marginal zone (3b) of hue.

  As an example, it is the 2nd printing image line (4) which consists of a micro character formed in the 1st printing image line (3a). Although it is set as a micro character as an example, this invention is not limited to this, A number, a character, a symbol, and / or a pattern etc. are mentioned. The second print image line (4) has the same hue as the first print image line (3a), and is light or blank. As shown in the sectional view of FIG. 2B, the first printed image line (3a) has a first marginal zone (3b) around the image line. The second printed image line (4) also has a second marginal zone (4a) of the same color as the first marginal zone (3b) around the image line. The reason why the second marginal zone (4a) is formed will be described later.

  The first print image line (3a) will be described with reference to FIG. As shown in FIG. 3 (a), the width (W1) or height (h1) of the first printed image line (3a) is in the range of 0.01 mm to 1 mm, more preferably 0.1 mm. It is the range of -0.5mm. When the width (W1) or the height (h1) exceeds 1 mm, it is likely to be imitated. When the width (W1) or the height (h1) is smaller than 0.01 mm, it becomes difficult to form a second print image line (4) described later.

  The typeface of the first printed image line (3a) is a known typeface that is generally used. Specifically, as shown in FIGS. 3 (b) to 3 (e), Mincho type, Gothic type. Font, line font, font type, etc., or an original font that is not generally used may be used. However, in consideration of the ease of forming the second print image line (4), it is Gothic. It is desirable to be. This is because the Gothic type has a wider character width than the Mincho type, line type or type type type, and it is easy to form the second printed image line (4).

  With reference to FIG. 4, the second printed image line (4) having the shape of a micro character will be described. As shown to Fig.4 (a), since the color of the 2nd printing image line (4) is the same as the ink which forms the 1st printing image line (3a), the 1st printing image line (3a ) And the same hue and light color, or white spots due to the absence of ink. The width (W2) or height (h2) of the second print image line (4), which is a micro character, is within the range of the width (W1) and height (h1) of the first print image line (3a) described above. Is set as appropriate. Specifically, it is in the range of 0.009 mm to 0.9 mm. If it is less than 0.009 mm, it is difficult to identify the second printed image line (4) with a magnifying glass. When it exceeds 0.9 mm, the printability of the first print image line (3a) described above is adversely affected.

  The typeface of the second print image line (4) may be the same or different from the typeface of the first print image line (3a) described above. The typeface used is a well-known typeface that is generally used as shown in FIGS. 4B to 4E, like the typeface of the first print image line 3a described above. A Mincho style, Gothic style, line typeface, font typeface, etc., or an original style that is not generally used may be used. The Gothic font has a wider width (W2) than the Mincho font, the line font, or the font font, and the second marginal zone (4a) can be easily formed.

  The color of the second marginal zone (4a) is the same as the ink that forms the first print image line (3a), and the second print image line (4) is formed by relief printing. It is the same color as one marginal zone (3b) and darker than the second print image line (4).

  The anti-counterfeit printed matter of the present invention has a fine second marginal zone (4a) generated in the contour of the second printed image line (4) formed in the first printed image line (3a). The interval between the first marginal zone (3b) and the second marginal zone (4a) is also fine. Furthermore, since the color of the first printed image line (3a) is lighter than both marginal zones (3b, 4a), it cannot be reproduced by a PC-related device.

  When copied by a copying machine, the second printed image line (4), the first marginal zone (3b), and the second marginal zone (4a) are fine and cannot be reproduced due to the resolution of the copying machine. Or it becomes a reproduction | regeneration defect.

Next, the relief printing plate surface for producing the first print image line (3a) and the second print image line (4) and the principle of the present invention will be described.

  FIG. 5 is an example of a ring used for a numbering device for forming a printed image line according to the present invention. FIG. 5 (a) is a side view of the ring (5), and FIG. It is a perspective view of a ring (5). As shown in FIG.5 (b), the ring (5) has the letterpress (6) which forms the 1st printing image line (3a) which is a type. In addition, although not described in FIG. 5, the recessed part formed in the letterpress (6) which forms the 2nd printing image line (4) is mentioned later.

  FIG. 6 is an enlarged view showing a part of the letterpress (6) which is the type of the ring (5). As shown to Fig.6 (a), the letterpress (6) which is the type of a ring (5) has the recessed part (6b) which is a type. As shown in the AA ′ sectional view of FIG. 6B, the relief plate (6) forms the projection (6a) and the second printed image line (4) formed on the projection (6a). It consists of a recess (6b). The depth of the concave portion (6b) is appropriately set within a range of 0.1 mm or more, although it depends on the height of the convex portion (6a). In the case of less than 0.1 mm, it becomes difficult to form a second marginal zone (4a) described later. The recess (6b) is formed by a laser.

  FIG. 7 shows an example of printing using the above-described ring (5). As shown in FIG. 7, when the ink (7) is applied to the relief plate (6), the ink (7) is not applied because the recess (6b) is fine, and the ink is applied only to the projection (6a). Is meated.

  As shown in FIG. 8A, the ink (7) supplied to the convex portion (6a) of the relief plate (6) is transferred to the substrate (2) by the printing pressure (S1) of the relief plate (6). . As shown in FIG. 8 (b), when the ink (7) is transferred to the base material (2) to form the first printed image line (3a), the printing pressure (S1) of the relief printing plate (6) is used. Since the ink (7) is crushed and pushed outward from the gap between the convex portion (6a) and the substrate (2), the first ink pool (7a) is generated at the end of the convex portion (6a). Thus, the first marginal zone (3b) is formed.

  Similarly, in the recess (6b), the ink (7) is crushed by the printing pressure (S1) of the relief plate (6) and pushed into the recess (6b) from the gap between the recess (6b) and the substrate (2). Therefore, the second ink pool (7b) is generated at the end of the recess (6b), whereby the second marginal (4a) is formed.

  Therefore, as shown in FIG. 9 (a), the first printed image line (3a) which is relief-printed with the ink (7) is formed around the first printed image line (3a). It has a first marginal zone (3b) formed by a first ink reservoir (7a) produced at the end. The second print image line (4) formed in the first print image line (3a) is the second print image line (7b) formed by the second ink pool (7b) generated at the end of the recess (6b). It has a marginal zone (4a).

  In this embodiment, since the first print image line (3a) and the second print image line (4) are formed with the same ink, the same hue and light color are obtained. By appropriately setting the depth of the concave portion (6b) of the relief (6) forming the image line (4), the second printed image line (4) is displayed as a white image as shown in FIG. 9B. It is also possible to form the second marginal zone (4a) around the image line of the second print image line (4), which is formed as a white line. As a method for forming white spots, the recess (6b) may be subjected to water or oil repellency treatment so that the ink does not enter the recess (6b).

  Therefore, the present invention provides intaglio printing by providing the concave portion (6b) on the convex portion (6a) of the relief plate (6) forming the first printed image line (3a) and the second printed image line (4). In the same manner as in the above, the second printed image line (4) consisting of a concave white portion due to the ink not entering the recess (6b), or the first formed by the ink entering the recess (6b). A second print image line (4) having the same hue and light color as the print image line (3a) of the first image is produced, and after transfer to the substrate (2), the relief image line formed by the relief plate (6) The contours of a certain first print image line (3a) and second print image line (4) are darkened by being raised by the first marginal zone (3b) and the second marginal zone (4a), respectively. It uses the principle. In this embodiment, both the first marginal zone (3b) and the second marginal zone (4a) are formed. As shown in FIG. 9C, the first print image line (3a) is formed. By appropriately setting the shape of the convex portion (6a) of the relief plate (6) that forms the first marginal zone (3b), it is possible to form only the second marginal zone (4a). .
