Description

The present invention relates to a printed matter capable of authenticity determination, which is excellent in authenticity determination effect, in which a plurality of fine constituent elements each composed of at least two pixels are regularly arranged in a lattice shape.

Anti-counterfeiting technology has been applied to valuable items such as banknotes, passports, securities, cards, stamps, product tags, toll road tickets, and various tickets. Therefore, a special print pattern is applied to such valuables, and the latent image is visually recognized by authenticating the print pattern by overlaying a discriminator consisting of a line filter or a discriminator consisting of a lenticular lens. A determination has been made.

For example, as a technology for discriminating authenticity with a discriminator consisting of a line filter, a background image portion printed with a line drawing line and a latent image portion with a line drawing angle with a different line angle from the background image portion are printed. At first glance, the background image portion and the latent image portion are difficult to see separately, but when the line filter is observed with a predetermined angle superimposed on the printed matter, the background image portion and the latent image portion are separated. A technique is known that can be visually recognized after being separated.

As a technique for discriminating authenticity by a discriminator composed of a lenticular lens, n is a predetermined integer of 2 or more, a band is formed by first to n bands arranged in parallel in the order of first to n, and a plurality of the aforementioned A printed matter forming an image by a band, wherein two are selected as bands to be exclusively pasted from the first to n bands corresponding to the band of the first predetermined image, and the outline of the hidden image Disclosed is a printed material in which a hidden image is revealed by superimposing a lenticular lens on a printed material on which an image formed by changing the pasting band from one selected belt to the other is printed. (See Patent Document 1).
JP 2003-094790 A (Pages 1-8, FIGS. 1-7)

However, in the printed matter whose authenticity is discriminated by the discriminator composed of the line filter and the printed matter described in Japanese Patent Laid-Open No. 2003-094790, is the latent image portion that becomes a hidden image and the surrounding background image portion constituted by line drawings? Alternatively, the latent image portion to be a hidden image and the background image portion around it are composed of lines drawn by halftone dots, and further, the arrangement of the lines of the latent image portion and the background image portion is misaligned. Therefore, there is a problem that the boundary between the latent image portion and the background image portion can be visually recognized even when only the printed material is observed. In addition, the design of the latent image portion is limited because it is formed with a line drawing.

In addition, the discriminator consisting of a line filter, when superimposed on a printed material, allows the latent image portion to be visually recognized only at a certain specific angle, so the tolerance for deviation when superimposed at a certain specific angle is narrow, It took time and effort to make the latent image portion appear at the stage where the authenticity is determined by superimposing it with the determination tool. Also, the line pitch of the line filter needs to match the pitch of the line pattern of the printed matter, and the line pitch of the line filter and the pitch of the line pattern forming the printed matter need to be almost the same. There was a limitation on the pitch width of the line filter. Further, the line filter is blocked by the line portion of the line line, and the latent image portion is not clearly visible.

In addition, since JP-A-2003-094790 forms a latent image with a line drawing line, the structure is simple and there is a risk of duplication. Further, a line-shaped lenticular lens is connected to a line of printed matter. Thus, there is a problem that it is difficult to visually recognize the latent image when the image is superimposed in a perpendicular direction or a line direction.

In view of the above, the present invention aims to solve the above-mentioned problems. A printed pattern is provided on a substrate, and the printed pattern is regularly formed by a fine component composed of at least two pixels. In a printed matter comprising a plurality of arranged and including at least one latent image portion composed of a first fine component and a background image portion composed of a second fine component in the periphery thereof, the fine component is , Having at least two colors and having different shapes of the first fine component and the second fine component, or having the same shape, the first fine component and the second fine component are mutually By changing the arrangement angle and the arrangement position, there is no possibility that the boundary between the latent image portion and the background image portion is visible with the naked eye even when only the printed material is observed, and the design of the latent image portion is not limited. Also, the lenticular on the discriminator By using a lens and forming a printed matter with a micro-structure, there is a wide tolerance for misalignment when overlapping at a certain angle, and it takes no effort at the stage of overlapping with a lenticular lens to determine authenticity. Therefore, it is not necessary to make the concavo-convex pitch of the lenticular lens and the arrangement pitch of the fine components of the printed material substantially the same, and the latent image portion is more clearly visible than before, and differs depending on the position or angle at which the printed material and the lenticular lens are superimposed. Since the latent image of a different color can be visually recognized, the authenticity discrimination effect is excellent. In addition, since the fine structure composed of at least two pixels can be formed in a complicated manner, it can be a printed material that is difficult to duplicate. Further, it is not necessary to make the lines of the image line misaligned in the latent image portion and the background image portion, and to make the number of screen lines different. Further, since the copy copied by the copying machine is visually recognized with different color tones between the background image portion and the latent image portion, it has a copy prevention effect. The present invention proposes the above-described printed matter capable of authenticating authenticity.

According to the present invention, a printed pattern is provided on a base material, and the printed pattern is formed by regularly arranging a plurality of microscopic components composed of at least two pixels, and includes at least one latent layer composed of a first microscopic component. In a printed material including an image image portion and a background image portion including a second fine component around the image image portion, the fine component has at least two colors, and the first fine component and the first fine component It is a printed matter having a different shape of the second fine structure and capable of determining authenticity, and the latent image portion is visually recognized when a lenticular lens is superimposed on the printed matter capable of determining authenticity. It is a printed matter that can be falsely identified.

According to the present invention, a printed pattern is provided on a base material, and the printed pattern is formed by regularly arranging a plurality of fine components each including at least two pixels, and includes at least one of the first fine components. In a printed material including one latent image portion and a background image portion formed of a second fine component around the latent image portion, the fine component has at least two colors, and the first fine component And the second micro-constructor are formed in the same shape, and the first micro-constructor and the second micro-constructor are prints that can authenticate authenticity with different arrangement angles. When a lenticular lens is superimposed on a printed matter capable of authenticating authenticity, the printed image is capable of authenticating authenticity formed by visually recognizing the latent image portion.

According to the present invention, a printed pattern is provided on a base material, and the printed pattern is formed by regularly arranging a plurality of fine components each including at least two pixels, and includes at least one of the first fine components. In a printed material including one latent image portion and a background image portion formed of a second fine component around the latent image portion, the fine component has at least two colors, and the first fine component And the second micro-constructor are formed in the same shape, and the printed matter capable of determining authenticity is different in the arrangement positions of the same color pixels forming the first micro-constructor and the second micro-constructor. When the lenticular lens is superimposed on the printed matter capable of authenticating authenticity, the printed matter can be determined genuinely by visually confirming the latent image portion.

According to the present invention, a printed pattern is provided on a substrate, and the printed pattern is formed by regularly arranging a plurality of fine components each including at least two pixels, and at least one latent image including the first fine components. In a printed material including an image portion and a background image portion including a second fine component around the image portion, the fine component has at least two colors, and the first fine component and the second fine component The shapes of the constituent elements are different, or the shapes are the same, and the first and second fine constituent elements are arranged at different angles to each other. Since the latent image portion and the background image portion are formed by the micro-constructor without forming the image image portion and the background image portion, the latent image portion and Non-visualization with no background image Excellent sex.

In addition, when the lenticular lens is observed over the printed material of the present invention, the latent image portion and the background image portion are separated and can be visually recognized as a latent image, so it is possible to determine whether the printed material is genuine. . By using the lenticular lens, the latent image portion can be visually recognized more clearly than before. Furthermore, by changing the position or angle at which the printed material of the present invention and the lenticular lens are superimposed, latent image images of different colors can be visually recognized, so that the authenticity discrimination effect is excellent. In addition, a latent image having a gradation in color is visually recognized depending on a position or an angle to be overlapped. Therefore, the present invention can be applied to valuable items such as banknotes, passports, securities, cards, stamps, product tags, toll road tickets, and various tickets.

In addition, since the latent image portion and the background image portion are formed with fine construction elements, it is possible to form a complicated design. Also, a lenticular lens is used as a discriminator and a printed matter is formed with the fine construction elements. By doing so, since the allowable range for the deviation when overlapping at a certain angle is wide, the latent image can be easily visually recognized at the stage of overlapping with a line-shaped lenticular lens and determining authenticity. In addition, it is not necessary to make the uneven pitch of the line-shaped lenticular lens and the arrangement pitch of the fine structure of the printed matter substantially the same, and the difference between the uneven pitch of the line-shaped lenticular lens and the arrangement pitch of the fine structure of the printed matter A wide allowable range can be formed.

In addition, since the latent image images of different colors can be visually recognized depending on the angle at which the printed material and the line-shaped lenticular lens are overlapped, the authenticity determination effect is excellent. In addition, by using a discriminator consisting of a line-shaped lenticular lens instead of a discriminator consisting of a conventional line filter, the latent image appears more clearly than the line filter. Visible.

In addition, since the fine structure composed of at least two pixels can be formed in a complicated manner, it can be a printed material that is difficult to duplicate. Further, depending on the design of the micro-constructor, it is not necessary to make the image lines misaligned between the latent image portion and the background image portion, and it is not necessary to make the number of screen lines different. Further, depending on the design of the fine structure, when copying with a copying machine, the copied material is divided into a latent image portion and a background image portion due to the scanning line of the copying device, and is visually recognized as a latent image. Therefore, it has a copy prevention effect. Even in a display image taken with a high-resolution camera-equipped mobile phone, digital video camera, or digital camera, the colors of the latent image portion and the background image portion can be distinguished and visually recognized.

Further, in FIG. 1, the two color pixels (5a, 5b) and the pixels (6a, 6b) forming the fine structure are formed apart from each other, but even if they are in contact with each other, some of them overlap each other. It may be. Therefore, the first fine component (5) and the second fine component (6) can be formed in a shape as shown in FIG. However, FIG. 2 is an example, and the present invention is not limited to this. In FIG. 1, the second microstructural elements (6) are regularly arranged by rotating clockwise by 30 ° with respect to the first microstructural elements (5). The fine structure (6) can be formed by rotating between 10 ° and 350 ° with respect to the first fine structure (5). More preferably, the latent image can be clearly recognized by forming the image by rotating within a range of 30 ° to 150 ° or 210 ° to 330 °. FIG. 3A shows the second fine component (6) rotated clockwise by 90 ° with respect to the first fine component (5), and FIG. 3 (b) shows the second fine component.

And regularly arranged at regular intervals in the Y direction. That is, each fine component of the first fine component (5) and the second fine component (6) is provided in a lattice shape. By forming in this way, when the printed matter (A1) that can authenticate the authenticity without overlapping the lenticular lenses as shown in FIG. 7 to be described later is observed with the naked eye, the first print region (3) and the first print region (3) When the printed region (4) of 2 is excellent in non-visibility and is not visually recognized, and the printed material (A1) can be discriminated with a lenticular lens as shown in FIG. The first print area (3) and the second print area (4) are separated, and the visibility that is visually recognized as a latent image is excellent. In FIG. 4, the lattice-like shape is regularly formed at regular intervals. However, as shown in FIG. 5, the first fine structure (5) and the second fine structure have a deviation (S) as shown in FIG. The child (6) may be arranged. Further, the present invention can be produced without making the number of screen lines different between the latent image portion and the background image portion. That is, the first fine component (5) and the second fine component (6) are provided in each unit.

Further, the second fine component (6) of the printed matter (A1) capable of authenticating authenticity is rotated at a predetermined angle (30 ° clockwise in the drawing) with respect to the first fine component (5). However, as shown in FIG. 6A, the second fine component (6) is shifted to a predetermined position with respect to the first fine component (5). A plurality of them may be regularly arranged.

Further, in the description of FIG. 1, the fine structure is rotated, but at least one type of pixel forming the second fine structure has the same color as at least one type of pixel forming the second fine structure. The effect of the present invention can also be obtained by shifting the pixel forming the first fine component to a predetermined position and / or rotating at a predetermined angle.

FIG. 7 is a diagram in the case where only the printed matter (A1) that can be determined as authenticity without overlapping the line-shaped lenticular lenses is observed with the naked eye. As shown in FIG. 7, the second fine structure (6) forming the second print region (4) is replaced with the first fine structure (5) forming the first print region (3). On the other hand, a plurality of pixels are regularly arranged by rotating 30 ° clockwise, but the shape is the same, and the pixel (5a) of the first fine component (5) and the second fine component ( The area of the pixel (6a) of 6) is the same or substantially the same, and the area of the pixel (5b) of the first fine structure (5) and the area of the pixel (6b) of the second fine structure (6) are the same. Or, since the first fine component (5) and the second fine component (6) are fine components, the first print region (3) and the second print are visually recognized. The area (4) is not divided, the first print area (3) and the second print area (4) are visually recognized in the same or almost the same color tone, and the latent image is visually recognized. It can not be. Therefore, only the printed pattern (2) is visually recognized, and the color of the printed pattern (2) is green, which is a mixed color of the pixels (5a, 5b) composed of cyan and yellow and the pixels (6a, 6b) composed of cyan and yellow. Visible.

FIG. 8 is a diagram in the case where the lenticular lens (L) is superimposed on the printed matter (A1) capable of determining authenticity and observed with the naked eye. In the lenticular lens (L), a plurality of bowl-shaped lenses are formed like a line. FIG. 8A is a view when the first fine component (5) forming the first print region (3) is overlapped at an angle of 0 °, and FIG. FIG. 8C is a view when the first fine component (5) forming one print region (3) is overlapped at an angle of 10 °, and FIG. 8C is a diagram illustrating the first print region (3). It is a figure at the time of overlapping at an angle of 90 degrees with respect to the 1st micro structure (5) which forms.

As shown in FIG. 8A, when the first fine structure (5) forming the first print area (3) is overlapped at an angle of 0 °, the first print area (3 ) Is visually recognized as a mixed color of cyan and ground color, the second print area (4) is visually recognized as cyan, and the first print area (3) and the second print area (4) are divided by the difference in color. The second print area (4) is visually recognized as a latent image. Further, when the first fine component (5) forming the first print region (3) is overlapped at an angle of 0 °, the first print region (3) has yellow and ground colors. The second print area (4) is visually recognized as yellow, the first print area (3) and the second print area (4) are divided by the difference in color, and the second print area ( 4) is visually recognized as a latent image.

As shown in FIG. 8B, when the first fine component (5) forming the first print region (3) is overlapped at an angle of 10 °, the first print region (3 ) And the second print area (4) are visually recognized as stripes of cyan, yellow, and ground color, but there is a phase difference between the stripes in the first print area (3) and the second print area (4). As a result, the first print area (3) and the second print area (4) are divided by the phase difference of the stripe, and the second print area (4) is visually recognized as a latent image.

As shown in FIG. 8C, when the first fine component (5) forming the first print region (3) is overlapped at an angle of 90 °, the first print region (3 ) Is visually recognized as a mixed color of cyan, yellow, and background color, and the second print area (4) has almost no enlarged area of the background, and is visually recognized as a mixed color of cyan and yellow. The area (3) and the second print area (4) are divided, and the second print area (4) is visually recognized as a latent image. In this way, since the latent image images of different colors can be visually recognized depending on the position or angle at which the printed material (A1) and the lenticular lens that can authenticate are overlapped, the authenticity determination effect is excellent. However, in the present invention, the position where the printed material and the lenticular lens are overlapped with each other depending on the color of the fine structure, the shape of the fine structure, the arrangement pitch of the fine structure, and the number of lines of the lenticular lens to be discriminated or Since the angle is different and the color in which the latent image is viewed is different, the present invention is not limited to the above description.

9 to 13 show the relationship between the first fine component (5) and the second fine component (6) of the printed matter (A1) capable of authenticating authenticity and the lenticular lens. However, the number of lines of the lenticular lens is an example, which is equal to the pitch of the first fine component (5) and the second fine component (6). FIGS. 9A and 10A are enlarged views of the boundary portion between the first print area (3) and the second print area (4) of the printed matter (A1) having a white background and capable of authenticating. This shows a portion that is magnified when the lenticular lenses are overlapped at 0 °. The lenticular lens enlarges a part or background of the pixel (5a, 5b) in the first print area (3) and a part or background of the pixel (6a, 6b) in the second print area (4). To enlarge.

FIG. 9B shows an enlarged view of the pixels (5a, 5b) and the pixels (6a, 6b) shown in FIG. 9 (a). In the first print area (3), the pixel (5a) is shown. Since the white color of the background is enlarged, it is enlarged and displayed in low density cyan as shown in FIG. 9C, and there is almost no area where the white color of the background is enlarged in the second print area (4). Since the pixel (6a) is enlarged, it is enlarged and displayed in high density cyan as shown in FIG. 9 (c). Therefore, the first print area (3) and the second print area (4) can be separated and visually recognized, and the latent image can be observed. FIG. 10B shows an enlarged view of the pixels (5a, 5b) and the pixels (6a, 6b) shown in FIG. 10 (a). In the first print area (3), the pixel (5b) Since the white of the background is enlarged, it is enlarged and displayed in low density yellow as shown in FIG. 10C, and there is almost no area in which the white of the background is enlarged in the second print area (4). Since the pixel (6b) is enlarged, it is enlarged and displayed in high density yellow as shown in FIG. 10 (c). Therefore, the first print area (3) and the second print area (4) can be separated and visually recognized, and the latent image can be observed. From the above, when the lenticular lenses are overlapped at 0 °, the latent images with different colors can be observed by changing the position where the lenticular lenses are overlapped. Will appear and be able to observe.

  FIG. 11 is an enlarged view of the boundary between the first print area (3) and the second print area (4) of the printed matter (A1) whose background is white and which can be detected as authenticity. A portion enlarged when a lenticular lens having the same pitch as the pitch of the constituent (5) and the second fine constituent (6) is overlapped at 10 ° is shown. In the first print area (3) and the second print area (4), the pixel (5a), the pixel (5b), the pixel (6a), the pixel (6b), and the base are regularly selected and enlarged. Therefore, it is observed as a regular stripe pattern of cyan, yellow, and white of the background. However, in the image enlargedly displayed by the lenticular lens, the region of the fine component regularly selected in the first print region (3) and the second print region (4) is different, so as shown in FIG. A phase difference occurs in the observed stripe pattern. Therefore, the first print area (3) and the second print area (4) can be separated and visually recognized, and the latent image can be observed.

  FIG. 13A is an enlarged view of the boundary portion between the first print area (3) and the second print area (4) of the printed matter (A1) whose background is white and which can be detected as authenticity. A portion that is enlarged when a lenticular lens having the same pitch as that of the first and second fine components (5) and (6) is overlapped at 90 ° is shown. FIG. 13B shows an enlarged view of the pixels (5a, 5b) and the pixels (6a, 6b) shown in FIG. 13 (a). In the first print region (3), A part of the pixel (5a) and the pixel (5b) is selected and enlarged with the same area, and the second print region (4) has almost no white area to be enlarged, and the pixel (6a) and the pixel (5a). A part of (6b) is selected and enlarged in the same area. However, since the pixels (5a, 5b) of the first print area (3) to be enlarged and the pixels (6a, 6b) of the second print area (4) to be enlarged have different microstructural shapes, Therefore, as shown in FIG. 13C, in the area of the enlarged image by the lenticular lens, there is a difference between the first print region (3) and the second print region (4). Therefore, as the gray image, the first print area (3) and the second print area (4) have a difference in shade of green, which is a mixed color of cyan, yellow, and white of the background, and the first print area ( 3) and the second print area (4) can be separated and visually recognized, and the latent image can be observed.

FIG. 14 is an example of a printed matter (A2) capable of determining authenticity of the present invention and a partially enlarged view thereof. As shown in FIG. 14, a printed pattern (2) in which a plurality of first fine components and the second fine components are arranged in a lattice pattern is provided on a substrate (1). It is a printed matter (A2) including a first print area (3) serving as a background image part and a second print area (4) serving as a latent image part, which can be determined as authenticity. The first print area (3) is formed around the second print area (4). As shown in the enlarged view of FIG. 14, in the first print region (3), the first fine component (5) composed of pixels (5a, 5b) of two colors (yellow and cyan in the drawing) is regular. Are arranged in multiple numbers. In the second print region (4), the second fine structure having the same color as that of the first fine structure (5) composed of pixels (6a, 6b) of two colors (yellow and cyan in the drawing) is different. A plurality of children (6) are regularly arranged. The area (5a1) of the yellow color pixel forming the first fine structure (5) and the area (6a1) of the yellow pixel forming the second fine structure have the same or almost the same relationship. Need to be. Further, the area (5b1) of cyan pixels forming the first fine structure (5) and the area (6b1) of cyan pixels forming the second fine structure have the same or substantially the same relationship. It is necessary to have. That is, the first fine structure (5) and the second fine structure (6) have different shapes, and the area of each color pixel forming the first fine structure (5) and the second size. The areas of the pixels of the respective colors forming the fine structure (6) must have the same or almost the same relationship. The color is not particularly limited.

Here, in FIG. 14, the two-color pixels (5a, 5b) and the pixels (6a, 6b) forming the fine constituent elements are formed in contact with each other. The parts may overlap. Therefore, the first microstructure (5) and the second microstructure (6) can be formed in a shape as shown in FIG. However, FIG. 15 is an example, and the present invention is not limited to this. In addition, the area of each color forming the first micro structure (5) and the area (6) of each color forming the second micro structure need to have the same or almost the same relationship. Here, “substantially the same” means that, for example, when the area of yellow of the pixel (5a) forming the first fine structure (5) is 1, the second fine structure is formed. It is necessary to form the yellow area (6) of the pixel (6a) to be within about 80% to 120%. Similarly, when the cyan area of the pixel (5b) forming the first fine structure (5) is 1, the cyan area (6) of the pixel (6b) forming the second fine structure Needs to be formed within about 80% to 120%. If it is not formed within this range, the first printed area (3) and the second printed area (4) are separated when the printed matter is observed with the naked eye without overlapping the lenticular lenses described later, and the latent image There is a possibility that (hidden image) is visually recognized.

Furthermore, as shown in FIG. 16, the printed matter (A2) capable of authenticating authenticity shown in FIG. 14 has the first fine component (5) and the second fine component (6) in the X direction. And regularly arranged at regular intervals in the Y direction. That is, each fine component of the first fine component (5) and the second fine component (6) is provided in a lattice shape. By forming in this way, when the printed matter (A2) that can be determined as authenticity without overlapping lenticular lenses as shown in FIG. 19 described later is observed with the naked eye, the first print region (3) and the first print region (3) When the printed material (A2) is excellent in non-visibility in which the print area (4) of 2 is not visually recognized in a divided manner and the lenticular lens is overlapped as shown in FIG. The first print area (3) and the second print area (4) are separated, and the visibility that is visually recognized as a latent image is excellent. In FIG. 16, the lattice-like shape is regularly formed at regular intervals. However, as shown in FIG. 17, the first microstructure (5) and the second microstructure are provided with a deviation (S). The child (6) may be arranged. Further, the present invention can be produced without making the number of screen lines different between the latent image portion and the background image portion.

In the description of FIG. 1 described above, it is described and explained that the shapes of the first fine structure (5) and the second fine structure (6) need to be different, but the first fine structure having the same color as each other. If the pixel forming the constituent element and the pixel forming the second micro constituent element have the same area or substantially the same area, at least one type of pixel forming the second micro constituent element has the second micro constituent element. The effect of the present invention can be obtained by forming the pixel forming the first fine component having the same color as that of at least one kind of pixel forming the child with different shapes. Further, as shown in FIG. 18A, in addition to the different shapes of the first microstructure (5) and the second microstructure (6), the second microstructure (6) A plurality of the fine components (5) may be regularly arranged by shifting to a predetermined position. In FIG. 18A, there is a deviation (s). Further, as shown in FIG. 18B, in addition to the different shapes of the first fine structure (5) and the second fine structure (6), the second fine structure (6) One fine component (5) may be shifted to a predetermined position and rotated at a predetermined angle to regularly arrange a plurality. In other words, the first microstructure and the second microstructure are different in arrangement angle from each other. In FIG. 18 (b), there is a deviation (s) and it is rotated 30 ° clockwise. In FIG. 18B, there is a deviation (s).

FIG. 19 is a diagram in the case where only the printed matter (A2) that can be determined as authenticity without overlapping lenticular lenses is observed with the naked eye. As shown in FIG. 19, the second fine structure (6) for forming the second print region (4) and the first fine structure (5) for forming the first print region (3) Although formed with differently shaped microstructures, the area of the pixel (5a) of the first microstructure (5) and the area of the pixel (6a) of the second microstructure (6) are the same or nearly the same. And the area of the pixel (5b) of the first micro-constructor (5) and the area of the pixel (6b) of the second micro-constructor (6) are the same or substantially the same, and the first micro-constructor Since (5) and the second fine component (6) are fine components, the first print region (3) and the second print region (4) are not distinguished by the naked eye, and the first print region (3) and the second print area (4) are visually recognized in the same or substantially the same color tone, and the latent image cannot be visually recognized. Therefore, only the print pattern (2) is visually recognized, and the color of the print pattern (2) is green, which is a mixed color of the pixels (5a, 5b) made of yellow and cyan and the pixels (6a, 6b) made of yellow and cyan. Visible.

FIG. 20 is a diagram in the case where the lenticular lens (L) is superimposed on the printed matter (A2) capable of authenticating authenticity and observed with the naked eye. The line-shaped lenticular lens (L) has a plurality of bowl-shaped lenses formed like lines. FIG. 20A is a diagram when the first fine component (5) forming the first print region (3) is overlapped at an angle of 0 °, and FIG. It is a figure at the time of overlapping at an angle of 90 degrees with respect to the 1st micro structure (5) which forms the 1st printing field (3).

Alternatively, the first print area (3) has almost no enlarged area of the background portion and is visually recognized in yellow, and the second print area (4) is visually recognized as a mixed color of yellow and the background color. The Therefore, the first print area (3) and the second print area (4) are divided by the difference in color, and the second print area (4) is visually recognized as a latent image. In this way, since the latent image images of different colors can be visually recognized depending on the position or angle at which the printed matter (A2) and the lenticular lens that can authenticate are overlapped, the authenticity determination effect is excellent. However, in the present invention, the position where the printed material and the lenticular lens are overlapped with each other depending on the color of the fine structure, the shape of the fine structure, the arrangement pitch of the fine structure, and the number of lines of the lenticular lens to be discriminated or Since the angle is different and the color in which the latent image is viewed is different, the present invention is not limited to the above description.

FIG. 21 and FIG. 22 show the relationship between the first fine component (5) and the second fine component (6) of the printed matter (A2) capable of authenticating authenticity and the lenticular lens. However, the number of lines of the lenticular lens is an example, which is equal to the pitch of the first fine component (5) and the second fine component (6). 21 (a), 21 (c), and 21 (e) show a first print area (3) and a second print area (4) of a printed matter (A2) whose background is white and whose authenticity can be determined. ) In which the pixels (5a, 5b) and the pixels (6a, 6b) are enlarged, and a portion that is enlarged when the lenticular lenses are overlapped at 0 ° is shown. The enlarged image by the lenticular lens of FIG. 21 (a) is shown in FIG. 21 (b), the enlarged image by the lenticular lens of FIG. 21 (c) is shown in FIG. 21 (d), and the enlarged image by the lenticular lens of FIG. This is shown in FIG.

In FIG. 21A and FIG. 21B, in the first print area (3), the white color of the pixel (5b) and the background is enlarged, so that it is enlarged and displayed in low density cyan. In the print area (4), since the white color of the pixel (6a) and the background is enlarged, it is enlarged and displayed in low density yellow. Therefore, the first print area (3) and the second print area (4) can be divided and visually recognized by the difference in color, and the latent image can be observed. In FIG. 21C and FIG. 21D, in the first print area (3), the white color of the pixel (5b) and the background is enlarged, so that it is enlarged and displayed in low density cyan. In the print area (4), since the pixel (6a) and the pixel (6b) are enlarged, there is almost no area where the white color of the background is enlarged, and the display is enlarged with a mixed color of yellow and cyan. Therefore, the first print area (3) and the second print area (4) can be divided and visually recognized by the difference in color, and the latent image can be observed. In FIG. 21 (e) and FIG. 21 (f), the first print area (3) has almost no white area to be enlarged, and the pixel (5a) is enlarged. In the second print area (4), the pixel (6a) and the white background are enlarged, so that they are enlarged and displayed in low density yellow. Therefore, the first print area (3) and the second print area (4) can be divided and visually recognized by the difference in color, and the latent image can be observed. From the above, when the lenticular lenses are overlapped at 0 °, the latent images with different colors can be observed by changing the position where the lenticular lenses are overlapped. Therefore, the latent images with different colors are alternately displayed by shifting the lenticular lenses. Appears and can be observed.

  22 (a) and 22 (c) show the pixels (5a, 2a) of the first print area (3) and the second print area (4) of the printed matter (A2) whose background is white and which can be detected as authenticity. 5b) and the pixels (6a, 6b) are enlarged, and a portion enlarged when the lenticular lenses are overlapped at 90 ° is shown. An enlarged image of the lenticular lens in FIG. 22A is shown in FIG. 22B, and an enlarged image of the lenticular lens in FIG. 22C is shown in FIG.

22 (a) and 22 (b), since the white color of the pixel (5a) and the background is enlarged in the first print area (3), it is enlarged and displayed in low density yellow. In the print area (4), since the white color of the pixel (6b) and the background is enlarged, it is enlarged and displayed in low density cyan. Therefore, the first print area (3) and the second print area (4) can be divided and visually recognized by the difference in color, and the latent image can be observed. In FIG. 22C and FIG. 22D, there is almost no area in which the white background is enlarged in the first print area (3), and the pixels (5a) and (5b) are enlarged. In the second print area (4), there is almost no area in which the base white is enlarged, and the pixel (6a) is enlarged, so that the pixel (6a) is enlarged. Is displayed. Therefore, the first print area (3) and the second print area (4) can be divided and visually recognized by the difference in color, and the latent image can be observed. From the above, when the lenticular lenses are overlapped at 90 °, the latent images with different colors can be observed by changing the position where the lenticular lenses are overlapped. Therefore, by shifting the lenticular lenses, the latent images with different colors are alternately displayed. Appears and can be observed.

The printed matter capable of authenticating the authenticity of the present invention can be a printed matter that is difficult to duplicate because a fine structure constituted by at least two pixels can be formed in a complicated manner. In addition, depending on the design of the fine structure, the fine structure having different shapes in the first print area and the second print area, or the same direction but the arrangement direction in the first print area and the second print area Are formed with different fine components, and thus a duplicate of a printed matter is visually recognized with different color tones in the background image portion and the latent image portion. The “replicated copy” as used herein refers to a copy obtained by copying a printed material with a copying machine, a display image when it is photographed with a high-resolution camera mobile phone, a digital video camera, or a digital camera.

  The size of the pixel for printing the printed matter capable of authenticating the authenticity of the present invention needs to be about 50 μm to 500 μm. Therefore, the size of the fine component needs to be about 100 μm to 1000 μm. If the pixel is smaller than 50 μm, it is difficult to produce a printed material. If the pixel is larger than 500 μm, the first printed region and the second printed region are divided by the naked eye, which may cause a risk. More preferably, the size of the pixel needs to be about 100 μm to 150 μm, and the size of the fine component is preferably about 200 μm to 300 μm. In addition, the pitch of the fine component for printing the printed matter capable of authenticating authenticity of the present invention needs to be about 150 μm to 1500 μm, and the pitch of the fine component is preferably about 250 μm to 400 μm.

  The lenticular lens for discriminating the printed matter of which the authenticity can be determined according to the present invention is particularly limited to a line-shaped lens as shown in FIG. 23A, a dot-like lens as shown in FIG. Although not a thing, a line-like lenticular lens can obtain the effect of this invention most.

For example, when the fine component of a printed matter capable of authenticity determination of the present invention is 200 μm and the pitch of the fine component is 254 μm, the lenticular lens for determining the printed matter capable of determining authenticity is 80 to 100 lines (line / Inch) of lines.

And the color must be the same, and the color pixel (5b) forming the first microstructure (5) and the color pixel (2) forming the second microstructure (6) 6b) needs to have the same or almost the same area and the same color. Further, the color pixel (5a) forming the first fine structure (5) and the color pixel (5b) forming the first fine structure (5) must be different in color. The color pixel (6a) forming the second fine structure (6) and the color pixel (6b) forming the second fine structure (6) need to be different in color. Here, the first fine structure (5) and the second fine structure (6) are described with two colors of pixels (5a, 5b) or pixels (6a, 6b). Without being limited to the above, the first fine component (5) and the second fine component (6) can be configured with at least two or more colors. That is, when the first fine structure (5) and the second fine structure (6) are formed with three colors, the number of pixels is three, and the first fine structure (5) and the second color are formed with four colors. In the case of forming the two fine components (6), the number of pixels is four.
