Description

The present invention relates to an image forming body that is applied to a valuable item such as banknote, passport, card, product tag, brand protection, etc. for which anti-counterfeiting, authenticity determination, and copy protection are required.

Valuables such as banknotes, passports, cards, product tags, and brand protection are not easily counterfeited or altered due to their nature, and a technical element that can determine whether the valuables are genuine is required. For example, as one of the technical elements, there is known a technique in which a latent image is visually recognized by observing a valuable item while being tilted, and authenticity determination is performed based on the presence or absence of the visual recognition. For example, a technology in which a printed image line is formed on a material having a concavo-convex shape formed by printing or the shape of a base material, and a latent image formed of the concavo-convex shape can be visually recognized when observed by tilting with reflected light. In addition, there is a technique in which the latent image is visually recognized when the shape and arrangement of the perforations are made different between the background region and the latent image region, and the tilted image is observed with transmitted light.

  As a technique for forming a printed image line on a material having a concavo-convex shape formed by the printing shape and viewing a latent image formed of the concavo-convex shape when observed by tilting with reflected light, for example, a partial The printed lines are printed with various line patterns, or relief patterns, or both patterns, which are expressed by different angles, raised with ink of the same or similar color as the printing material. Either various line-drawing lines or halftone-dotting lines having a fixed interval on the line, or both of the lines are printed on the printing line by the color of the printing line and other colored inks other than colorless and transparent. When viewed from the front by printing with parallel or inclined, it is possible to confirm only one of the various line or halftone lines or the two lines with the regular intervals, from an oblique direction. Observation Then, the pattern constituted by the raised image line can be easily confirmed by the non-constant positional relationship generated between the raised printed image line and the printed image line having the constant interval, and the reverse oblique direction. A latent image printed matter is disclosed in which the light and darkness of the pattern can be reversed and confirmed when observed from (Patent Document 1).

As a technique for forming a printed image line on a material having a concavo-convex shape formed by the shape of the substrate and observing the image with a concavo-convex shape when observed by tilting with reflected light, for example, a partial angle Various materials other than the color of the material and colorless and transparent to the material having the uneven shape formed by embossing any of the various line patterns, or relief patterns, or both patterns representing the pattern by making different Depending on the color of the ink, either one of the various line-drawing lines or the halftone-dotting lines with a certain interval, or both of the drawing lines may be parallel or inclined with respect to the portion constituting the portion other than the above-mentioned concavo-convex pattern. When printed from the front, when viewed from the front, only one of the various line-drawing lines or halftone-dotting lines composed of straight lines with a fixed interval, or both drawing lines, can be confirmed. As a result, the pattern formed by the concavo-convex shape can be easily confirmed by the non-constant positional relationship generated between the concavo-convex shape and the printed image line having the constant interval, and observed from the opposite oblique direction. A latent image pattern formed body is disclosed in which the light and darkness of a pattern can be reversed and confirmed (Patent Document 2).

As a technique for forming a perforated shape, arrangement, etc. in the background area and the latent image area on the base material, and observing the image by tilting with transmitted light, the latent image can be visually recognized. To make a latent image appear, for example, on a base material, fine perforations constituting the background portion and perforations constituting the information portion are formed, and perforations in the background portion and the information portion are perforated. The shape, size, and pixel angle are formed so that at least one of them is different, and when the authenticity determination formed body is observed with reflected light, the background portion and the information portion cannot be distinguished and cannot be visually recognized. A technique is disclosed in which the background portion and the information portion are visually recognized when observed by the method (Patent Document 3).

(Image forming body A1)
FIG. 3 shows an image forming body A1 and a partially enlarged view thereof. A predetermined area 5 on one surface of the substrate 1 is provided, and a cut-in image 4 a is formed in the predetermined area 5. The cut-in image 4a is divided into a first region that becomes the background region 7 and a second region that becomes the latent image region 8, and the first region that becomes the background region 7 has a line of the concave portion 2a and a line of the convex portion 3a. Are alternately arranged at a predetermined pitch and formed in a line shape, and the lines of the concave portions 2b and the lines of the convex portions 3b are alternately arranged at a predetermined pitch in the second region to be the latent image region 8, It is formed to have a concavo-convex shape. The arrangement direction of the line of the concave part 2a and the line of the convex part 3a is arranged in the first area to be the background area 7, and the arrangement direction of the line of the concave part 2b and the line of the convex part 3b is arranged in the second area to be the latent image area 8. It is formed in one direction (same direction). The cut-in image 4a is produced with the cross-sectional shape of FIG. Further, the predetermined pitch of the concave portion 2a and the convex portion 3a serving as the background region 7 and the predetermined pitch of the concave portion 2b and the convex portion 3b serving as the latent image region 8 are formed at the same pitch and out of phase. The The predetermined pitch for the background region 7 and the predetermined pitch for the latent image region 8 are the same pitch, and are preferably shifted from each other by approximately a half pitch. It is preferable that the line of the recessed part 2a and the line of the recessed part 2b are the same depth. The image forming body A1 is formed by arranging the perforations 9 penetrating the base material at a predetermined pitch in the first area to be the background area 7 and the second area to be the latent image area 8 in a line shape. The perforations 9 formed so as to penetrate the substrate 1 have the same predetermined pitch as the concave and convex portions in the latent image region 8 and the background region 7 and have the same phase (latent image region 8 and background region). 7 has no perforation shift). The perforations 9a formed in the first region to be the background region 7 are formed along the concave portion 2a, and the perforations 9b formed in the second region to be the latent image region 8 are formed along the convex portion 3b. Is done. In other words, the perforations 9 a formed in the first region that becomes the background region 7 are formed along the concave portion that is the lowest portion of the substrate 1, and the perforations 9 b that are formed in the second region that becomes the latent image region 8. Is formed along the convex portion which is the highest portion of the substrate 1. The effect of the image forming body A1 will be described below.

When the image forming body A1 is observed from the vertical direction with respect to the image forming body A1 with reflected light with the naked eye as shown in FIG. 4A, as shown in FIG. It cannot be visually recognized, and only the perforated group 10 is visually recognized. The penetration is a technique that cannot be visually recognized by reflected light, and is generally visible by transmitted light. Further, the penetration image 4a is camouflaged by the perforations 9, and thus is difficult to visually recognize. . Further, since the perforations 9 penetrate through the base material, a contrast is generated between the region where the perforations 9 are formed and the region where the perforations 9 are not formed, so that the perforation group 10 is visible.

When the image forming body A1 is observed with the reflected light as shown in FIG. 5 (a) at a specific angle from the X1 direction or the X2 direction shown in FIG. 3, as shown in FIG. 5 (b), A latent image 8 made up of the inserted image 4a can be visually recognized. As shown in FIG. 5C, the perforation 9b formed on the line of the convex portion 3b of the latent image region 8 can be visually recognized as it is, but the perforation 9a formed on the line of the concave portion 2a of the background region 7 It is blocked by the line of the convex portion 3a and cannot be visually recognized. For this reason, only the perforation 9b formed in the line of the convex part 3b of the latent image area | region 8 is visually recognized, and the latent image image (P) formed by the perforation 9b can be visually recognized.

When the image forming body A1 is observed from the vertical direction with respect to the image forming body A1 with the transmitted light with the naked eye as shown in FIG. 6A, as shown in FIG. It can be visually recognized. The penetration is a technique that cannot be visually recognized by reflected light but generally visible by transmitted light. Further, as shown in FIG. 6C, the area of the recess 2a in the background area 7 and the area of the recess 2b in the latent image area 8 is larger than the area of the protrusion 3a in the background area 7 and the protrusion 3b in the latent image area 8. Since the thickness of the substrate 1 is thin, the amount of transmitted light is strong. Further, since the perforations 9 are formed in the region of the concave portion 2a in the background region 7 and the region of the convex portion 3b in the latent image region 8, the amount of transmitted light is strong. By increasing the amount of transmitted light in this way, the visibility of the inserted image 4a is improved. However, in this case, the thickness is limited to a substrate having a thickness of about 80 μm to 150 μm (particularly a paper substrate), and in the case of a clear penetration having gradation or the like, the sharpness may be lost by perforation.

When the image forming body A1 is observed with the naked eye with transmitted light as shown in FIG. 7A at a specific angle from the X1 direction or the X2 direction shown in FIG. 3, as shown in FIG. A latent image 8 made up of the inserted image 4a can be visually recognized. As shown in FIG. 7C, the transmitted light of the perforation 9b formed on the line of the convex part 3b of the latent image area 8 can be seen as it is, but is formed on the line of the concave part 2a of the background area 7. The transmitted light of the perforation 9a is blocked by the line of the convex portion 3a and cannot be visually recognized, or the amount of transmitted light is reduced. For this reason, the transmitted light of the perforation 9b formed in the line of the convex part 3b of the latent image area | region 8 is visually recognized, and the latent image image (P) formed with the transmitted light of the perforation 9b can be visually recognized.

In the image forming body A1, the perforations 9a formed in the first region serving as the background region 7 are formed along the concave portion 2a, and the perforations 9b formed in the second region serving as the latent image region 8 are convex. Although formed along the portion 3b, the perforation 9a formed in the first region serving as the background region 7 is formed along the convex portion 3a and formed in the second region serving as the latent image region 8. The perforation 9b may be formed along the recess 2b. When manufactured in this way, the latent image (P) described with reference to FIGS. 5 and 7 is visually recognized with the negative and the positive reversed.

(Image forming body A2)
FIG. 8 shows an image forming body A2 and a partially enlarged view thereof. A predetermined area 5 is provided on one surface of the base material 1, and a scraped image 4 b is formed in the predetermined area 5. The cut-in image 4b is divided into a first area that becomes the background area 7 and a second area that becomes the latent image area 8, and the first inclined area 11a and the second area are divided into the first area that becomes the background area 7. The lines of the concave portions 2a having the inclined regions 11b and the lines of the convex portions 3a are alternately arranged at a predetermined pitch, are formed in a line shape, and the first inclined regions 11a and the second regions to be the latent image regions 8 The line of the concave part 2b having the second inclined region 11b and the line of the convex part 3b are alternately arranged at a predetermined pitch, are formed in a line shape, and have an uneven shape. The arrangement direction of the line of the concave part 2a and the line of the convex part 3a is arranged in the first area to be the background area 7, and the arrangement direction of the line of the concave part 2b and the line of the convex part 3b is arranged in the second area to be the latent image area 8. It is formed in one direction (same direction). The cut-in image 4b is produced with the cross-sectional shape of FIG. Further, the predetermined pitch of the concave portion 2a and the convex portion 3a serving as the background region 7 and the predetermined pitch of the concave portion 2b and the convex portion 3b serving as the latent image region 8 are formed at the same pitch and out of phase. The The predetermined pitch for the background region 7 and the predetermined pitch for the latent image region 8 are the same pitch, and are preferably shifted from each other by approximately a half pitch. It is preferable that the line of the convex part 3a and the line of the convex part 3b are the same height. The image forming body A2 is formed by arranging the perforations 9 penetrating through the base material at a predetermined pitch in the first area serving as the background area 7 and the second area serving as the latent image area 8 in a line shape. The perforations 9 formed so as to penetrate the substrate 1 have the same predetermined pitch as the concave and convex portions in the latent image region 8 and the background region 7 and have the same phase (latent image region 8 and background region). 7 has no perforation shift). The perforations 9a formed in the first region to be the background region 7 are formed along the first inclined region 11a, and the perforations 9b formed in the second region to be the latent image region 8 are the second It is formed along the inclined region 11b. The effect of the image forming body A2 will be described below.

When the image forming body A2 is observed from the vertical direction with respect to the image forming body A2 with the naked eye with reflected light as shown in FIG. 9 (a), as shown in FIG. It cannot be visually recognized, and only the perforated group 10 is visually recognized. The penetration is a technique that cannot be visually recognized by reflected light but is generally visible by transmitted light. Further, since the penetration image 4b is camouflaged by the perforations 9, it is difficult to visually recognize by the naked eye. . Further, since the perforations 9 penetrate through the base material, a contrast is generated between the region where the perforations 9 are formed and the region where the perforations 9 are not formed, so that the perforation group 10 is visible.

When the image forming body A2 is observed with the naked eye with the reflected light as shown in FIG. 10A at a specific angle from the X1 direction shown in FIG. 8, as shown in FIG. The latent image 8 consisting of 4b can be visually recognized. When observed from the X1 direction at a specific angle, the region of the second inclined region 11b can be visually recognized, but the region of the first inclined region 11a cannot be visually recognized. Therefore, the perforation 9a formed along the first inclined region 11a formed in the first region serving as the background region 7 is formed in the second region serving as the latent image region 8 without being visually recognized. The perforations 9b formed along the second inclined region 11b are visually recognized. For this reason, only the perforations 9b formed in the second inclined region 11b of the latent image region 8 are visually recognized, and the latent image (P) formed by the perforations 9b can be visually recognized. Further, when observed from the X2 direction, only the perforation 9a in the background area is visually recognized, and the latent image (P) formed by the perforation 9a in the background area is visually recognized.

When the image forming body A2 is observed from the vertical direction with respect to the image forming body A2 with the naked eye with transmitted light as shown in FIG. 11 (a), the image forming body A2 shows a clean image 4b as shown in FIG. 11 (b). It can be visually recognized. The penetration is a technique that cannot be visually recognized by reflected light but is generally visible by transmitted light. Further, as shown in FIG. 11C, the perforations 9a formed in the first region that becomes the background region 7 are formed along the first inclined region 11a and become the second latent image region 8. Since the perforations 9b formed in the region are formed along the second inclined region 11b, the amount of transmitted light is increased. Therefore, the visibility of the inserted image 4b is improved by increasing the amount of transmitted light. However, in this case, the thickness is limited to a substrate having a thickness of about 80 μm to 150 μm (particularly a paper substrate), and in the case of a clear penetration having gradation or the like, the sharpness may be lost by perforation.

When the image forming body A2 is observed with the naked eye with transmitted light as shown in FIG. 12A at a specific angle from the X1 direction shown in FIG. 8, as shown in FIG.

The perforations formed in the latent image region, which are arranged along any one of the region and the lower region of the uneven shape, are formed in the first inclined region, the uneven shape of the uneven shape of the latent image region. This is different from the type in which the perforation of the background region is formed in any one of the types of the second inclined region, the high region of the uneven shape, and the low region of the uneven shape.

The perforation pitch is preferably about 3: 1 to 1: 3. More preferably, the perforation pitch is about 1: 1. The diameter of the perforations is not particularly limited, but is preferably about 50 μm to 500 μm. If it is smaller than 50 μm, it will be difficult to produce, and if it is larger than 500 μm, it will be easy to replicate and the forgery prevention effect will be reduced. By gradually changing the size of the perforations, brightness and darkness can be obtained in the latent image described later. Therefore, the pitch in the X direction and the pitch in the Y direction of the perforations 9 are preferably in the range of about 150 to 1500 μm. The shape of the perforation is not particularly limited, and can be manufactured in a circular shape, a polygonal shape, a special shape, or the like, and these can be combined. As shown in FIG. 29, a character (A) may be formed by a group of fine perforations, and the characters may be arranged at a predetermined pitch, or the perforations of a special shape (character: A) may be arranged at a predetermined pitch.

The perforations are preferably formed in a direction perpendicular to the substrate. However, even if the perforations are formed in an oblique direction with respect to the base material, the observation angle is different from that in which the perforations are formed in a direction perpendicular to the base material, but the effect of the present invention can be obtained. In addition, as shown in FIG. 30A, the diameter of the perforations may be smaller with respect to the depth direction of the base material. Further, as shown in FIG. 30B, perforation may be performed in an oblique direction with respect to the base material. Moreover, the perforation group 10 can form a character, a pattern, etc., as shown to Fig.31 (a). As shown in FIG. 31 (b), the diameters of the perforations may be different.
