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, when a printed image line is formed on a substrate having a concavo-convex shape formed by an ink pile or the shape of the substrate, and a latent image formed by the concavo-convex shape can be visually recognized when observed by tilting with reflected light In addition, there is a technique in which a latent image can be visually recognized when the substrate is formed with different shapes and arrangements of the perforations in the background region and the latent image region on the substrate, and observed by tilting with transmitted light.

  As a technique for forming a printed image line on a material having a concavo-convex shape formed on the base material with a heap of ink and visually observing the latent image formed by the concavo-convex shape when tilted with reflected light, for example, The printing material is raised with ink of the same or similar color to the printing material, either the various line patterns that represent the pattern by partially varying the angle, or the relief pattern, or both patterns And apply various line-drawing lines or halftone-dotting lines having a constant interval on the printed image line, or both of the image lines by the color of the printed image line and other different colored inks other than colorless and transparent. By observing from the front by printing with parallel or inclined to the print image line, only one of the various line image or halftone image line with the constant spacing or both image lines can be confirmed. , When viewed from the direction of the image, the pattern formed by the raised image lines can be easily confirmed by the non-constant positional relationship generated between the raised printed image lines and the printed image lines having a certain interval. A latent image printed matter has been disclosed in which the light and darkness of the pattern can be reversed and confirmed when observed from an oblique direction (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 it by tilting with reflected light, a latent image formed by the concavo-convex shape can be visually recognized. Different colors other than the color of the material and colorless and transparent on the material with the uneven shape formed by embossing any of the various line patterns, relief patterns, or both patterns representing the pattern by different angles Depending on the ink of other colors, either the various line-drawing lines or the dot-dotting lines with a constant interval, or both the drawing lines are parallel to the portion constituting the portion other than the above-mentioned concavo-convex pattern or By observing from the front by printing with an inclination, it is possible to confirm only one of various line-drawing lines, halftone-dotting lines, or both-line drawing lines composed of straight lines with a certain interval. When observed from the direction, the pattern formed by the concave / convex shape can be easily confirmed by the non-constant positional relationship generated between the concave / convex shape and the printed image line having the constant interval. A latent image pattern formed body is disclosed, which can be confirmed by observing the light and darkness of the pattern reversed when observed (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. When the true / false discrimination formed body is observed with reflected light, the background part and the information part cannot be seen separately, but tilted with transmitted light. A technique is disclosed in which the background portion and the information portion are viewed separately when observed (Patent Document 3).

On the base material, a number of fine background perforations that are difficult to see and information perforations arranged in a shifted manner from the background perforations are formed to constitute a true / false discrimination formed body. , Blue) is disclosed (Patent Document 4) that enables true / false discrimination by placing on a color element screen in which a large number of color elements exhibiting any one of (blue) is arranged.

(Image forming body A1)
FIG. 5 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 perforated image 4 a is formed in the predetermined area 5. The perforated image 4a is divided into a first region which is the background region 7 and a second region which is the latent image region 8, and a perforation 9a penetrating the base material 1 is provided in the first region which is the background region 7. The perforations 9b penetrating the base material 1 are arranged at a predetermined pitch in the second region which is arranged in a pitch and formed in a line shape and is a latent image region 8, and is formed in a line shape. The line-shaped arrangement direction composed of the perforations 9a of the first area which is the background area 7 and the line-shaped arrangement direction of the perforations 9b of the second area which are the latent image areas 8 are one direction (the same direction). Formed. Furthermore, the predetermined pitch of the line-shaped predetermined pitch that becomes the background area 7 and the predetermined pitch of the line-shaped predetermined pitch that becomes the latent image area 8 are formed at the same pitch and out of phase. 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. In the latent image area 8 and the background area 7, the pitch of the line consisting of the concave part 2 and the convex part 3 formed by squeezing the base material 1 has the same pitch as the line-like pitch formed by perforation. In addition, the image forming body A1 is formed with the same phase (the latent image region 8 and the background region 7 are not displaced in the concave portion 2 and the convex portion 3). The recesses 2 are preferably the same depth. It is preferable that the convex part 3 is the same height. It is preferable that the perforations 9a and the perforations 9b have the same diameter and the same shape. The concave portion 2 and the convex portion 3 are produced with the cross-sectional shape of FIG. The perforations 9a formed in the first region which is the background region 7 are formed along the concave portion 2, and the perforations 9b formed in the second region which is the latent image region 8 are formed along the convex portion 3. Is done. In other words, the perforations 9 a formed in the first region that is 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 is 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 formed body A1 is observed from the vertical direction with respect to the image formed body A1 with reflected light as shown in FIG. 6A, the perforated image 4a is visually recognized as shown in FIG. 6B. The latent image area 8 and the background area 7 cannot be identified. This is a range in which the phase shift between the perforations 9a formed in the background region 7 and the perforations 9b formed in the latent image region 8 cannot be identified with the naked eye. Therefore, the perforated image 4a can be visually recognized, but the latent image region 8 and the background region 7 cannot be identified.

When the image forming body A1 is observed with the reflected light as shown in FIG. 7A at a specific angle from the X1 direction or the X2 direction shown in FIG. 5, as shown in FIG. The latent image area 8 and the background area 7 of the perforated image 4a are identified, and the latent image 8 can be visually recognized. As shown in FIG. 7C, the perforation 9b formed on the line of the convex portion 3 of the latent image area 8 can be seen as it is, but the perforation 9a formed on the line of the concave portion 2 of the background area 7 is It is blocked by the line of the convex portion 3 and cannot be visually recognized. For this reason, only the perforation 9b formed in the line of the convex part 3 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 naked eye with transmitted light as shown in FIG. 8 (a), the perforated image 4a is visually recognized as shown in FIG. 8 (b). can do. Further, the lines of the concave portion 2 and the convex portion 3 can be confirmed. 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. 8C, the recesses of the background region 7 and the latent image region 8 are formed on the substrate 1 more than the protrusions of the background region 7 and the latent image region 8. Since the thickness is thin, the amount of transmitted light is strong. Furthermore, since the perforated area is formed in the concave area of the background area 7 and the convex area of the latent image area 8, the amount of transmitted light is strong. Thus, the visibility of the penetration 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 A1 is observed with the naked eye with transmitted light as shown in FIG. 9A at a specific angle from the X1 direction or the X2 direction shown in FIG. 5, as shown in FIG. The latent image area 8 and the background area 7 of the perforated image 4a are identified, and the latent image 8 can be visually recognized. As shown in FIG. 9C, the transmitted light of the perforation 9b formed on the line of the convex part 3 of the latent image area 8 can be seen as it is, but is formed on the line of the concave part 2 of the background area 7. The transmitted light of the perforation 9a is blocked by the line of the convex portion 3 and cannot be visually recognized, or the amount of transmitted light is reduced.

When the image forming body A7 is observed from the vertical direction with respect to the image forming body A7 with reflected light as shown in FIG. 24 (a), the perforated image 4g is visually recognized as shown in FIG. 24 (b). The latent image area 8 and the background area 7 cannot be identified. This is a range in which the phase shift between the perforations 9a formed in the background region 7 and the perforations 9b formed in the latent image region 8 cannot be identified with the naked eye. Therefore, the perforated image 4g can be visually recognized, but the latent image region 8 and the background region 7 cannot be identified. The embossing of the concave portion 2 and the convex portion 3 is generally a technique that can be visually recognized by reflected light. However, since the concave portion 2 and the convex portion 3 are camouflaged by the perforations 9, they are difficult to visually recognize.

The transmitted light of the perforation 9a is blocked by the line of the convex portion 3 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 3 of the latent image region 8 is visually recognized, and the latent image (P) formed by the transmitted light of the perforated 9b can be visually recognized.

Therefore, the back surface of the base material is the back surface of the image forming body A7, and the perforations formed in the first region which is the background region are formed along the convex portion, and are formed in the second region which is the latent image region. A perforation is formed along the recess. When the rear surface of the image forming body A7 is observed with the naked eye with reflected light or transmitted light in a specific direction and a specific angle, the latent image region and the background region can be identified and the latent image can be visually recognized. The perforations formed in the convex line in the background area can be visually recognized as they are, but the perforations formed in the concave line in the latent image area are blocked by the convex line and cannot be visually recognized.

Furthermore, the predetermined pitch of the line-shaped predetermined pitch that becomes the background area 7 and the predetermined pitch of the line-shaped predetermined pitch that becomes the latent image area 8 are formed at the same pitch and out of phase. 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. In the latent image region 8 and the background region 7, the pitch of the line consisting of the concave portion 2 and the convex portion 3 having the first inclined region 11 a and the second inclined region 11 b formed by embossing on the substrate 1 is perforated. The image forming body A8 has the same pitch as the line-shaped pitch to be formed and has the same phase (the latent image area 8 and the background area 7 have no deviation between the concave portion 2 and the convex portion 3). . The recesses 2 are preferably the same depth. It is preferable that the convex part 3 is the same height. It is preferable that the perforations 9a and the perforations 9b have the same diameter and the same shape.

The perforations 9a formed in the first region which is the background region 7 are formed along the first inclined region 11a, and the perforations 9b formed in the second region which is the latent image region 8 are the second It is formed along the inclined region 11b. The effect of the image forming body A8 will be described below.

When the image forming body A8 is observed from the vertical direction with respect to the image forming body A8 with reflected light with the naked eye as shown in FIG. 29 (a), the perforated image 4h is visually recognized as shown in FIG. 29 (b). The latent image area 8 and the background area 7 cannot be identified. This is a range in which the phase shift between the perforations 9a formed in the background region 7 and the perforations 9b formed in the latent image region 8 cannot be identified with the naked eye. Therefore, the perforated image 4h can be visually recognized, but the latent image region 8 and the background region 7 cannot be identified. The embossing of the concave portion 2 and the convex portion 3 is generally a technique that can be visually recognized by reflected light. However, since the concave portion 2 and the convex portion 3 are camouflaged by the perforations 9, they are difficult to visually recognize.

When the image forming body A8 is observed with the naked eye with reflected light as shown in FIG. 30 (a) at a specific angle from the X1 direction shown in FIG. 28, as shown in FIG. 30 (b), the perforated image 4h The latent image area 8 and the background area 7 are identified, and the latent image 8 can be visually recognized. As shown in FIG. 30 (c), the perforations 9 b formed along the second inclined region 11 b of the latent image region 8 can be visually recognized as they are, but along the first inclined region 11 a of the background region 7. The perforations 9a formed in this manner cannot be visually recognized because they are formed along the first inclined region 11a. For this reason, only the perforations 9b formed along the second inclined region 11b of the latent image region 8 are visible, and the latent image (P) formed by the perforations 9b can be viewed. When observing at a specific angle from the X2 direction, the negative / positive of the latent image is reversed.

When the image forming body A8 is observed from the vertical direction with respect to the image forming body A8 with the transmitted light with the naked eye as shown in FIG. 31 (a), as shown in FIG. 3 cannot be visually recognized, and only the perforated image is visually recognized. Embossing is generally a technique that can be visually recognized with reflected light, and the embossing is difficult to visually recognize on a base material that can obtain a large amount of transmitted light. Furthermore, since the concave portion 2 and the convex portion 3 are camouflaged by the perforations 9, they are difficult to visually recognize with the naked eye.

When the image forming body A8 is observed with the naked eye with transmitted light as shown in FIG. 32 (a) at a specific angle from the X1 direction shown in FIG. 28, as shown in FIG. 32 (b), the perforated image 4h The latent image area 8 and the background area 7 are identified, and the latent image 8 can be visually recognized. As shown in FIG. 32 (c), the transmitted light of the perforation 9b formed along the second inclined area 11b of the latent image area 8 can be seen as it is, but the first inclined area of the background area 7 The transmitted light of the perforation 9a formed to form along 11a cannot be visually recognized because it is formed along the first inclined region 11a, or the amount of transmitted light decreases. For this reason, the transmitted light of the perforation 9b formed along the second inclined region 11b of the latent image region 8 is visually recognized, and the latent image (P) formed by the transmitted light of the perforated 9b can be visually recognized. When observing at a specific angle from the X2 direction, the negative / positive of the latent image is reversed.

In the image forming body A8, the perforations 9a formed in the first region which is the background region 7 are formed along the first inclined region 11a and are formed in the second region which is the latent image region 8. 9b is formed along the second inclined region 11b, but the perforation 9a formed in the first region which is the background region 7 is formed along the second inclined region 11b, and the latent image region The perforations 9b formed in the second region 8 may be formed along the first inclined region 11a. When manufactured in this way, the latent image (P) described with reference to FIGS. 30 and 32 is visually recognized with the negative and the positive reversed.

On the back surface of the image forming body A8, the line of the concave portion 2 formed on the surface becomes a convex portion, and the line of the convex portion 3 formed on the surface becomes a concave portion. Therefore, the back surface of the base material is the back surface of the image forming body A8. The perforations formed in the first region which is the background region are formed along the second inclined region, and the second region which is the latent image region. The perforations formed in are formed along the first inclined region. When the back surface of the image forming body A8 is observed with the naked eye with reflected light or transmitted light at a specific angle from the X1 direction, the latent image region and the background region can be identified and the latent image can be visually recognized. The perforations formed in the second inclined area of the background area can be viewed as they are, but the perforations formed in the first inclined area of the latent image area cannot be visually recognized. For this reason, only the perforations formed in the second inclined region of the background region are visually recognized, and the latent image (P) formed by the perforations can be visually recognized. That is, the negative and positive images are visually recognized by reversing from the latent image confirmed from the surface of the image forming body 2.

This is a range in which the phase shift between the perforations 9a formed in the background region 7 and the perforations 9b formed in the latent image region 8 cannot be identified with the naked eye. Therefore, the perforated image 4i can be visually recognized, but the latent image region 8 and the background region 7 cannot be identified. The embossing of the concave portion 2 and the convex portion 3 is generally a technique that can be visually recognized by reflected light. However, since the concave portion 2 and the convex portion 3 are camouflaged by the perforations 9, they are difficult to visually recognize.
