  Embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments to be described below, and various other embodiments can be implemented within the scope of the technical idea described in the claims.

(First embodiment)
FIG. 1 is a plan view and an enlarged view of a latent image showing a forgery prevention formed body (hereinafter referred to as “formed body”) (S) in the present invention.

  The printed matter (T) shown in FIG. 1A is a valuable printed matter such as a banknote, a passport, and an identification card, and is a gift certificate in FIG. 1A. The formed body (S) has the formed body (S) in a printing region (Z) provided at least in part on the base material (1) which is a medium that can be printed on the surface of paper, plastic card, or the like. ing.

  FIG.1 (b) is a schematic diagram which shows the structure of a formation body (S), and FIG.1 (c) is sectional drawing of a formation body (S). As shown in FIG. 1B and FIG. 1C, the formed body (S) overlaps the first latent image (A), the second latent image (B), and the visible image (C). Are arranged.

  As shown in FIGS. 2 (a) and 2 (b), the formed body (S) can be visually recognized by superimposing the visible image (C) visible from the front and the discriminating tool (F). Latent image (A) and a second latent image (B) that can be visually recognized by changing the observation angle. Hereinafter, the configuration will be described in detail.

  First, the first latent image (A) formed on the substrate (1) will be described using the configuration diagram of FIG. FIG. 3A is a plan view for explaining the first latent image (A). One latent image (A) is an image that can be visually recognized by overlapping the discriminating tool (F). The image lines constituting the first latent image (A) will be described in detail later, but when the substrate (1) is tilted and observed, the image lines constituting the visible image (C) are shielded. It is an image.

  FIG. 3B is an enlarged view of a part of the region (P) in FIG. The first latent image (A) has a first image line (2) having a bulge, which is regularly arranged in the first direction (X1) at a first pitch (D1). Become.

  The first pitch (D1) takes into consideration the printing method and the line width (W1) of the first line (2), and the line width (W1) of the first line (2), which will be described later. It is appropriately set within the range of the image line width that is the sum of the image line width of the third image line (4) forming the visible image (C) and 500 μm or less.

  The formed body (S) of the present embodiment will be described later in detail on the visual recognition principle, but the third image line (4) forming the visible image (C) is changed from the other image lines by changing the observation angle. By being shaded, the image that can be visually recognized changes. Therefore, the first pitch (D1) has the image line width (W1) of the first image line (2) and the image line width of the third image line (4) forming the visible image (C). If it is less than the added line width, an image that can be visually recognized due to a change in observation angle cannot be clearly recognized, which is not preferable.

  On the contrary, when the first pitch (D1) exceeds 500 μm, the plurality of first image lines (2) constituting the first latent image (A) are visually distinguished and visually recognized one by one. Is done. Therefore, when the area which comprises a printing area | region (Z) is narrow, since the designability of a 1st latent image (A) falls, it is unpreferable.

  The first latent image (A) has a pattern portion (A1), a background portion (A2), and a contour portion (A3) because the phases of some of the plurality of first image lines (2) arranged are different. It is divided into. In FIG. 3A, the pattern portion (A1) represents the number “123”, but is not limited thereto, and may be a character, a figure, a pattern, or the like.

  Note that the different phases in the present embodiment means that the phases are different in the first direction (X1) in which the plurality of first image lines (2) are arranged.

  In the first image line (2), it is most desirable that the phases are different at a pitch that is substantially half of the first pitch (D1) where the first image line (2) is arranged. This is to maintain high visibility of an image that can be visually recognized by a change in an observation angle, which will be described later, and a visible image (C). Hereinafter, the first image line (2) forming the pattern portion (A1) is defined as the 1a image line (2b), and the first image line (2) forming the background portion (A2) is defined as the first image line (b). This will be described as a line (2a).

  FIG. 3C is a cross-sectional view taken along the line X-X ′ in FIG. The image line width (W1) and image line height (h1) of the first image line (2) are determined in consideration of the first pitch (D1) and the image line widths of other image lines. ) It is appropriately set within a range of 50 to 450 μm.

  When the line width (W1) of the first image line (2) is less than 50 μm, it is not preferable because it is difficult to form a sufficient image line height (h1) depending on the ink used. When the image line width (W1) exceeds 450 μm, the range in which the third image line (4) that forms the visible image (C) can be arranged at a position that does not overlap with the first image line (2) is narrow. Thus, the line width (W1) of the third line (4) becomes narrower. Therefore, it is difficult to visually recognize the visible image (C), which is not preferable.

  The drawing height (h1) of the first drawing line (2) having a rise is taken into consideration in consideration of the first pitch (D1) and the drawing width and drawing height of other drawing lines. (H1) It is appropriately set within a range of 20 to 60 μm.

  When the height (h1) of the first image line (2) is less than 20 μm, the third image line (4) that forms the visible image (C) is sufficiently obtained when the observation angle is changed. It is not preferable because it cannot be shielded. Further, when the image line height (h1) exceeds 60 μm, it is difficult to visually recognize the visible image (C), and it is difficult to stably maintain the shape of the first image line (2). Absent.

  As shown in FIG. 3B, the contour portion (A3) that is the contour of the pattern portion (A1) and the contour portion (A3) has a smaller area ratio than the first image line (2). It is formed by an image line (2c).

  FIG. 4 is a schematic diagram for explaining the contour line (2c). FIG. 4A shows a plurality of first image lines (2) arranged in the first direction (X1).

  For example, the pattern of the first image line (2N1, 2N2, 2N3, 2N4), which is a part of the plurality of arranged first image lines (2), is made different in the first direction (X1). When the area (A1) and the background part (A2) are divided, as shown in FIG. 4 (b), the first image line (2b) and the background part (A2) constituting the pattern part (A1) are formed. In the image line (2a) of 1b, discontinuity of the image line occurs in the contour of the pattern portion (A1) indicated by the predetermined region (K1, K2) in FIG. 4 (b).

  Note that the contour of the pattern portion (A1) in the present embodiment is not the entire boundary between the pattern portion (A1) and the background portion (A2), but as shown in FIG. In X1), the 1a image line (2b) forming the pattern portion (A1) and the 1b image line (2a) forming the background portion (A2) are arranged adjacent to each other. .

  A density difference is generated at a portion where the discontinuity of the image line occurs compared to a region where the image line is continuous. Therefore, as shown in FIG. 5A, the boundary between the pattern portion (A1) and the background portion (A2) can be visually recognized with the naked eye, and the pattern portion (A1) which is a latent image is visually recognized in a state of relief. Will be.

  Therefore, as shown in FIG. 4C, the contour portion (A3) is formed in order to reduce the density difference at the boundary between the pattern portion (A1) and the background portion (A2). The contour portion (A3) is composed of a contour image line (2c) arranged between the 1a image line (2b) and the 1b image line (2a).

  In a discontinuous portion of the image line, the 1a image line (2b) and the 1b image line (2a) are adjacent to each other in the first direction (X1) without a gap as in the predetermined region (K1). If this occurs, the contour image line (2c) is arranged by replacing the 1a image line (2b) and the contour image line (2c).

  In the present invention, the term “adjacent” means that at least a part of two adjacent drawing lines are in contact with each other.

  In addition, when a discontinuous portion of the image line occurs due to an excessive gap between the 1a image line (2b) and the 1b image line (2a) as in the predetermined region (K2), An outline image line (2c) is arranged between the 1b image line (2a) and the 1a image line (2b).

  The contour image line (2c) is formed in a predetermined area (K1, K2) with an image area ratio approximately half of the 1b image line (2a) forming the background portion (A2). By arranging the contour line (2c), as shown in FIG. 5 (b), the density imbalance between the pattern portion (A1) and the background portion (A2) in the naked eye is alleviated by the contour portion (A3). The

  As shown in FIG. 4C, the contour image line (2c) includes a 1a image line (2b) constituting the pattern portion (A1) and a 1b image line (2b) forming the background portion (A2). 2a) has a blank portion (2d) between them, and a plurality of them are arranged with different phases from the 1a image line (2b) and the 1b image line (2a). As shown in FIG. 4 (d), the 1b image line (2a) is not adjacent to the 1a image line (2b) and the 1b image line (2a), but in the predetermined area (K1, K2). By halving the image line width (W1), it is also possible to obtain a contour image line (2c) having a substantially half image line area ratio.

  However, although the details of the formed body (S) of the present invention will be described later, it is formed by laminating fine image lines constituting each image. Specifically, the image line is further laminated on the first image line (2) constituting the first latent image (A).

  As shown in FIG. 4D, when the line width of the contour line (2c) is half the line width of the 1b line (2a), the line area ratio is approximately half. It is necessary to further narrow the line width of the line to be stacked thereon. Therefore, high printing accuracy is required at the time of manufacture.

  In recent years, it has become possible to create a raised image line by an ink jet printer. However, when the formed body (S) having the configuration shown in FIG. If an ink jet printer having a small nozzle diameter is not used, the image lines cannot be stacked, and the ink falls on the substrate (1). In addition, since inks are stacked, high ink landing position accuracy is required during manufacturing.

  Furthermore, even when it is created, it is difficult to maintain its shape in the process of distributing it as a precious printed matter, and the image line may be lost and the latent image may become invisible.

  From the above, the contour line (2c) constituting the contour part (A3), the background line (2b) constituting the pattern part (A1), and the background as shown in FIG. It is not adjacent to the 1b image line (2a) constituting the part (A2), and is arranged at a substantially half image area ratio.

  In FIG. 4C, the line width (W1) of the 1b image line (2a) and the image line width of the contour image line (2c) are the same, but this is not restrictive. If the space (2d) is arranged between the image line (2b) and the 1b image line (2a), a circle shown in FIG. 4 (e), a rectangle shown in FIG. 4 (f), Although not shown, any shape such as an ellipse or a triangle can be used.

  Further, the outline image line (2c) can be arranged at an arbitrary position in the predetermined area (K1, K2) as long as it does not overlap with other image lines, but the 1a image line (2b). It is preferable to arrange it at the center between the 1b and the 1b image line (2a).

  By disposing in the center between the 1a image line (2b) and the 1b image line (2a), it is possible to further alleviate the density imbalance of the first latent image (A). Become.

  Note that in FIG. 4 described above, the rectangular first latent image (A) has been described as an example, but a second latent image (B) described later is placed on the first latent image (A). Any shape can be selected as long as the size can be arranged.

  In the region (P) of FIG. 5B, a hatched contour portion (A3), a pattern portion (A1), and a background portion (A2) are arranged. In this case, since the arrangement of the contour line (2c) that alleviates the density imbalance of the first latent image (A) is different, it will be described with reference to the drawings.

  FIG. 6 is a schematic diagram for explaining the contour line (2c) in the region (P) of FIG. FIG. 6A shows a plurality of first image lines (2) arranged in the first direction (X1).

  In FIG. 6A, a predetermined region (K3) indicates a part of the pattern portion (A1) that is the region (P) of FIG. 5A described above, that is, a part of the numeral “2”.

  The first image line (2N1, 2N2, 2N3, 2N4), which is a part of the plurality of first image lines (2) arranged in a part of the numeral “2” shown in the predetermined area (K3). ) In the first direction (X1) and divided into the pattern portion (A1) and the background portion (A2), as shown in FIG. 6B, as shown in FIG. 6B. In addition, the 1a image line (2b) constituting the pattern portion (A1) and the 1b image line (2a) constituting the background portion (A2) are not drawn in the outline of the pattern portion (A1). Continuation occurs.

  In FIG. 4 described above, as shown in the predetermined region (K3) of FIG. 6B, the outline of the pattern portion (A1) is the pattern portion (A1) in the first direction (X1). It was a place where the 1a image line (2b) to be formed and the 1b image line (2a) forming the background part (A2) were all arranged adjacent to each other. Even in places that are partially adjacent to each other, such as the 1a image line (2b) that forms the pattern portion (A1) and the 1b image line (2a) that forms the background portion (A2), In this embodiment, the contour of the pattern portion (A1) is used.

  Next, as shown in FIG. 4 (c), as shown in FIG. 6 (c), in order to reduce the density difference at the boundary between the pattern portion (A1) and the background portion (A2), the first 1a image is displayed. The contour line (2c) is arranged between the line (2b) and the 1b line (2a).

  Depending on the shape of the pattern portion (A1), the distance between the contour image line (2c) and the adjacent first image line (2) arranged with the blank portion (2d) may be different. For example, in FIG. 6C, a predetermined area (K4) indicated by a thick line is an outline image line (2c) and a 1b image line (2a) which is the adjacent first image line (2). The distance (J) is too empty compared to the contour line (2c) in the other FIG.

  In the plurality of contour lines (2c), the distance between the contour line (2c) and the adjacent first first line (2), the 1a line (2b) and the 1b line (2a), is If they are different, a density difference occurs at the boundary between the pattern portion (A1) and the background portion (A2). For example, as shown in the predetermined area (K4) in FIG. 6 (c), when the gap is too large compared to the contour line (2c) in the other FIG. 6 (c), the density is low (white). ) By being visually recognized, the concealability of the first latent image (A) that can be visually recognized using the discriminator decreases.

  Since there is no density difference at the boundary between the pattern portion (A1) and the background portion (A2), as shown in the predetermined region (K4) in FIG. The shape of a part of the contour image line (2c) is made different so that the distances between the 1-image line (2b) and the 1-b image line (2a), which are the 1-image line (2), are equal. Are preferably arranged.

  In the predetermined region (K4) indicated by a thick line in FIG. 6D, the distance between the first 1a image line (2b) and the 1b image line (2a) is equal to the blank portion (2d). The shape of the contour line (2c) is different from other contour lines (2c). For example, in FIG. 6D, the two contour lines (2c) are arranged, so that the shape is different from the place where the other one contour line is arranged. In addition, when making distance equal, as shown in FIG.6 (d), it may be arrange | positioned adjacently or may be arrange | positioned with a clearance gap.

  In addition, as an arrangement in which the shapes of the other contour lines (2c) are made different from each other, by increasing the line width of one contour line (2c) arranged in the predetermined region (K4), It is also possible to equalize the distance to the image line (2).

  Thus, the user can freely design the shape of the pattern portion (A1) by arranging the contour line (2c) that forms the contour portion (A3) as appropriate in accordance with the shape of the pattern portion (A1). It becomes possible to do.

  In the predetermined area (K4) in FIG. 6D, the contour line (2c) is adjacent to the first direction (X1) without any gap, but the visibility of the pattern portion (A1) is reduced. If not, they can be arranged separately as appropriate.

  The first image line (2) having a bulge is formed on the substrate (1) by performing planographic printing and letterpress printing using a bulging material such as foamed ink as ink. Further, as another forming method, intaglio printing and stencil printing, or hard copy output by an ink jet printer or the like capable of printing a swelled ink is used.

  The color material used for the first image line (2) is not particularly limited, but the third image line (4) that forms a visible image (C) when the substrate (1) is tilted and observed. It is desirable that the color material has a lightness lower than that of the color material used for the third image line (4).

  Next, the first image line (2) will be described. FIG. 7 is a diagram illustrating an example of an image line. The image line is a known image line such as a straight line, a sine wave, a triangular wave, a sawtooth wave, or a rectangular wave as shown in FIGS. 7A, 7B, 7C, and 7D. That is. In addition, as shown in FIGS. 7E, 7F, 7G, 7H, 7I, and 7J, a circular shape, a polygonal shape, and a character shape are used. A pixel in which the pixels and the dots are configured in a linear shape is also an image line in the present invention. In the present embodiment, the image line is described as a linear image line illustrated in FIG.

  Next, the second latent image (B) formed on the first latent image (A) will be described. FIG. 8A is a plan view for explaining the second latent image (B). The second latent image (B) is a symbol that is visible when observed obliquely with respect to the substrate (1). In FIG. 8A, the alphabet of NPB is used, but not limited to this, it may be a letter, a number, a pattern, or the like.

  FIG. 8B is an enlarged view of a part of the region (P) in FIG. In FIG. 8A, only the second image line (3) is schematically shown, but the first image line (2) is shown in FIGS. 8B and 8C. In order to show the stacked state of the second image line (3), the first image line (2) is shown by a dotted line.

  In the second latent image (B), the second image line (3) having a bulge is regularly plural in the same first direction (X1) as the direction in which the first image line (2) is arranged. It is arranged.

  As described above, the formed body (S) of the present embodiment can be viewed by the third image line (4) constituting the visible image (C) being shielded by another image line due to a change in the observation angle. The image will change. Thus, in order to shield the third image line (4) with the first image line (2) and the second image line (3), the three image lines (2, 3, 4) are in the same direction. To place.

  The second image lines (3) constituting the second latent image (B) are all stacked on the first image line (2) constituting the first latent image (A). To do. Therefore, in accordance with the shape (symbol) of the second latent image (B), as shown in FIG. 8B, the 1a image line (a) constituting the first latent image (A) described above (see FIG. 8B). 2b), the second image line (3) is arranged on the 1b image line (2a) and the contour image line (2c).

  Therefore, the second latent image (B) is formed on the 2a image line (3b) formed on the 1a image line (2b) and on the 1b image line (2a). The second image line (3a) and the second image line (3c) formed on the contour image line (2c). Similar to the first latent image (A), the 2a image line (3b) and the 2b image line (3a) have different phases, but the 2c image line (3c) causes non-uniform density. By being relaxed, it is possible to visually recognize as an image having a uniform density to the naked eye.

  FIG. 8C is a cross-sectional view taken along the line X-X ′ in FIG. The image line width (W2) of the second image line (3) takes into consideration the image line widths of the first pitch (D1) and other image lines (2, 4), and the first image line (2). In the same manner as above, the image line width (W2) is appropriately set within the range of 50 to 450 μm. If the line width (W2) of the second image line (3) exceeds the image line width (W1) of the first image line (2) arranged below, the second latent image that can be visually recognized by being tilted. The image image (B) becomes visible even in the front, which is not preferable.

  The height (h2) of the second image line (3) having a swell is the first pitch (D1) and the image lines of the first image line (2) and the third image line (4). In consideration of the width and the image line height, similarly to the first image line (2), the image line height (h2) is appropriately set within a range of 20 to 60 μm. The second image line (3) having a swell is applied on the base material (1) by the same formation method as the first image line (2) described above, and the description thereof is omitted.

  The second image line (3) is formed of the second color material, and the second color material includes the first image line (2) disposed below the second image line (3). The first color material to be formed has the same color. By making the first color material and the second color material have the same color, it is possible to distinguish and visually recognize the first image line (2) and the second image line (3) when viewed from the front. The second latent image (B) cannot be identified.

  In addition, the same color in the present invention includes a difference in hue that is indistinguishable or difficult to distinguish when two image lines are viewed under natural light.

  As another configuration, the second color material is a color material having transparency, and the first color material is a color material having a lightness lower than that of the second color material. For example, when the first image line (2) is formed of a black color material and the second image line (3) is formed of cyan having transparency, the cyan color having transparency is arranged below. It is permeated and absorbed by the black color, and is visually recognized as black from the front.

  The transmission absorption in the present embodiment means that when a color material having a lightness lower than that of the semi-transparent color material is formed under the semi-transparent color material, and the two color materials are viewed from the front, the lightness It means that a translucent color material cannot be identified by a low color material.

  Therefore, the second color material is a translucent color material, and the first color material is a color material having a lightness lower than that of the second color material. In addition, when viewed from the front, the first image line (2) and the second image line (3) cannot be distinguished and viewed, and the second latent image (B) cannot be identified. Become. Hereinafter, in the present embodiment, the second color material will be described as a translucent color material, and the first color material will be described as a color material having a lightness lower than that of the second color material.

  Next, a visible image (C) that is an image visible from the front will be described. FIG. 9A is a plan view for explaining the visible image (C). In FIG. 9A, the visible image (C) is a figure of three diamonds, but is not limited to this, and may be a letter, a number, a pattern, or the like.

  FIG. 9B is an enlarged view of a part of the region (P) in FIG. Although the visible image (C), the first latent image (A) and the second latent image (B) described above are arranged in the region (Z) on the substrate (1), The third image line (4) constituting the visible image (C), the first image line (2) and the second image line (3) arranged in a stacked manner are arranged at positions where they do not overlap. Therefore, the third image line (4) and the first image line (2) and the second image line (3) arranged in a stack are alternately arranged one by one in the first direction (X1). By arranging, the third image line (4) is shielded by the first image line (2) due to the change in the observation angle.

  In the visible image (C), the third image line (4) is regularly arranged in the same first direction (X1) as the direction in which the first image line (2) and the second image line (3) are arranged. It is arranged in plural.

  As described above, the formed body (S) of the present embodiment can be viewed by the third image line (4) constituting the visible image (C) being shielded by another image line due to a change in the observation angle. The image will change. Thus, in order to shield the third image line (4) with the first image line (2) and the second image line (3), the three image lines (2, 3, 4) are in the same direction. To place.

The third image line (4) constituting the visible image (C) is less than or equal to the image line length of the first image line (2) constituting the first latent image (A). Place it at a position that does not overlap with the image line (2).
The drawing line length of the first drawing line (2) is the length of the first drawing line (2) in the direction (X2) perpendicular to the first direction (X1) that is the drawing line width direction. It is.

  Note that the third image line (4) is adjacent to the first image line (2) as shown in FIG. 9 (b) if it does not overlap the first image line (2). Even if it arrange | positions and it arrange | positions with a clearance gap although not shown in figure, either is possible. However, in order to make the third image line (4) constituting the visible image (C) easily shielded by other image lines due to the change in the observation angle, as shown in FIG. It is preferable to be arranged adjacent to the image line (2).

  By arranging the third image line (4) below the image line length of the first image line (2) having a bulge, all the third image lines (4) are changed by the observation angle. It is shielded by the first image line (2). Thus, the formed body (S) has a complete image change effect from the visible image (C) to the second latent image (B).

  Therefore, in accordance with the shape (symbol) of the visible image (C), as shown in FIG. 9 (b), the first a-line (2b) and the first image line (2b) constituting the first latent image (A) described above. The third image line (4) is arranged at a position adjacent to the image line (2a) and the contour image line (2c) of 1b in the first direction (X1).

  As described above, the visible image (C) is disposed at a position adjacent to the 3a line (4b) and the 1b image line (2a) disposed at a position adjacent to the 1a image line (2b). The third image line (4a) and the third image line (4c) disposed adjacent to the contour image line (2c). Similar to the first latent image (A), the 3a image line (4b) and the 3b image line (4a) have different phases, but the 3c image line (4c) causes non-uniform density. By being relaxed, it is possible to visually recognize as an image having a uniform density to the naked eye.

  FIG. 9C is a cross-sectional view taken along the line X-X ′ in FIG. The image line width (W3) and image line height (h3) of the third image line (4) consider the image line widths of the first pitch (D1) and the other image lines (2, 3), The line width (W3) is set to 25 to 250 μm and the line height (h3) is 15 μm or less as appropriate.

  When the line width (W3) of the third line (4) is less than 25 μm, it is difficult to reproduce with a general printing method, and it is difficult to identify a visible image (C) that can be viewed from the front. Therefore, it is not preferable.

  On the contrary, when the line width (W3) of the third image line (4) exceeds 250 μm and the image line height (h3) of the third image line (4) exceeds 15 μm, the observation angle Since the image line that forms an image that can be visually recognized due to the change in the image line has to be formed at an image line height of 250 μm or more, the image line is missing and the durability of the formed body (S) decreases. It is not preferable.

  The third image line (4) is formed on the substrate (1) by hard copy output by lithographic printing, intaglio printing, an ink jet printer or the like. The third image line (4) is formed by hard copy output by printing on the base material (1) using a known printing method and a printing plate, ink, or the like suitable for the printing method.

  The third image line (4) is formed of the third color material. The third color material is not particularly limited, but a color having low brightness and clearly distinguishable from the surface color of the substrate (1) is desirable. For example, when the surface color of the base material (1) is a high brightness color such as white or cream, and the third color material is a high brightness color such as yellow, the surface color of the base material (1) and the first color The color material 3 is not preferable because it is difficult to distinguish.

  Next, the laminated state of the first latent image (A), the second latent image (B), and the visible image (C) will be described. FIG. 10A is a schematic diagram showing a stacked state of the first latent image (A), the second latent image (B), and the visible image (C) on the substrate (1). A visible image (C) is formed in the print region (Z) on the substrate (1), and a first latent image (A) is formed on the visible image (C), and the first image is further formed. A second latent image (B) is formed on the latent image (A).

  Note that the overlapping of the first latent image (A), the second latent image (B), and the visible image (C) means that the images overlap each other, and each image is configured as described above. This does not mean that all the lines to be overlapped.

  FIG.10 (b) is a schematic diagram which shows the enlarged view of the one part area | region (P) in Fig.10 (a), FIG.10 (c) cut | disconnected XX 'in FIG.10 (b). It is sectional drawing. In addition, FIG.10 (b) shows the state by which all the images (A, B, C) were laminated | stacked on the base material (1).

  As shown in FIGS. 10B and 10C, the second image line (3) forming the second latent image (B) forms the first latent image (A). The first image line (2) is stacked on the first image line (2) so as to be equal to or smaller than the image line width. Further, the third image line (4) forming the visible image (C) is arranged at a position not overlapping the first image line (2) and the second image line (3) arranged in a stacked manner. The

  When the third image line (4) overlaps the first image line (2) and the second image line (3) arranged in a stacked manner, the visible image (C) visually recognized from the front is obtained. It is visually unclear and undesirable. Further, a part of the second latent image (B) which is a latent image is visually recognized from the front, which is not preferable.

  Next, the visual recognition state of the formed body (S) having the above configuration will be described. Fig.11 (a) is a schematic diagram at the time of observing a formation body (S) from the 1st observation angle (E1) which is a front with respect to a base material (1), FIG.11 (b) is shown in FIG. FIG. 11A is an enlarged view of a part of the region (P) in FIG. 11A, and FIG. 11C is a cross-sectional view taken along the line XX ′ in FIG.

  In addition, since the 1st observation angle (E1) with respect to a formation body (S) and the 1st observation angle (E1) with respect to a base material (1) are the same, below, a base material (1) is abbreviate | omitted. The formed body (S) is observed from the first observation angle (E1), and the other observation angles are the same.

  Since the third image line (4) is arranged at a position that does not overlap the first image line (2) and the second image line (3) arranged in a stacked manner, the first observation angle ( When observed from E1), it becomes visible and the visible image (C) is visually recognized.

  The first image line (2) arranged in a stacked manner is formed by a first color material having low brightness, and the second image line (3) is formed by a second color material having colored transparency. Yes. Further, the image line width of the first image line (2) is formed to be equal to or larger than the image line width of the second image line (3).

  Therefore, the color material of the second image line (3) formed in the upper layer is transmitted and absorbed by the first image line (2) formed in the lower layer, and the two image lines (b1, c1) are distinguished with the naked eye. The first latent image (A) composed of a plurality of first image lines (2) arranged in the lower layer is visually recognized.

  As described above, when the formed body (S) is observed from the first observation angle (E1), the visible image (C) and the first latent image (A) are visible as shown in FIG. However, the visible image (C) is significantly visually recognized by the difference in area ratio and / or hue between the visible image (C) and the first latent image (A). Hereinafter, in the present embodiment, even when two images (for example, image A and image B) become visible at a predetermined observation angle, one image (for example, the difference in area ratio and / or hue) , Image A) is significantly visible.

  The hue referred to in the present invention distinguishes the relative color difference of the entire image, such as “reddish color” or “blued color”, and includes “red” or “blue It does not indicate an absolute color such as “

  Next, a case where the formed body (S) is tilted and observed will be described. FIG. 12A is a schematic diagram when the formed body (S) is observed from the second observation angle (E2) that is oblique with respect to the base material (1), and FIG. FIG. 12A is an enlarged view of a part of the region (P) in FIG. 12A, and FIG. 12C is a cross-sectional view taken along the line XX ′ in FIG. The second observation angle (E2) is an observation angle when observed from the same direction as the first direction (X1) with respect to the formed body (S).

  As shown in FIG. 12C, when the formed body (S) is observed from the second observation angle (E2), the third image line (4) is the first image line arranged in a stacked manner. The blind spot (G1) of (2) and the second image line (3) becomes a blind spot (G1) and is not visible, so that the second latent image (B) composed of a plurality of second image lines (3) is visually recognized. Is done.

  Since the second image line (3) is raised and arranged on the first image line (2), a part of the surface color of the substrate (1) A second latent image composed of a plurality of second image lines (3) that is transmitted and absorbed by the second color material forming the image line (3) and is visually recognized with the hue of the second image line (3). An image (B) is visually recognized.

  Further, the first image line (2) on which the second image line (3) is not stacked is visually recognized while maintaining the density and hue of the first image line (2).

  Therefore, when the formed body (S) is observed from the second observation angle (E2), as shown in FIG. 12A, the first latent image (A) and the second latent image (B). Can be visually recognized, but the second latent image (B) is visually recognized due to the difference in area ratio and / or hue between the first latent image (A) and the second latent image (B). The

  Next, the case where the formed body (S) is observed using the discriminating tool (F) will be described. FIG. 13A is a schematic diagram when the discriminating tool (F) is observed while being superimposed on the printing region (Z) applied to the formed body (S), and FIG. FIG. 13C is an enlarged view of a part of the region (P) in FIG. 13A, and FIG. 13C is a cross-sectional view taken along the line XX ′ in FIG. The discriminating tool (F) uses a lenticular lens.

  As shown in FIG. 13A, when the discriminating tool (F) overlaps the print area (Z), the first latent image (A) becomes obvious and the pattern portion (A1) becomes visible.

  As described above, a lenticular lens is used for the discriminating tool (F). Since the lens pitch of the lenticular lens is the same as the first pitch (D1), as shown in FIG. 13C, the center of the lens (L1) that is the focal point of the lenticular lens that is the discriminator (F). ) When the 1a-th image line (2b) constituting the pattern portion (A1) is arranged below, the observer views the 1a-th image line (2b) constituting the pattern portion (A1) from the first. It seems to have expanded in the direction (X1).

  Therefore, when the discriminating tool (F) is superposed on the formed body (S) and observed, the pattern portion (A1) of the first latent image (A) becomes visible as shown in FIG. .

  When the formed body (S) is observed using the discriminating tool (F), the image to be visualized is changed by overlapping the discriminating tool (F). FIG. 14A is a schematic diagram when the discriminating tool (F) is observed while being shifted in the print region (Z) applied to the formed body (S), and FIG. FIG. 14C is an enlarged view of a part of the region (P) in FIG. 14A, and FIG. 14C is a cross-sectional view taken along the line XX ′ in FIG. The discriminator (F) uses the same lenticular lens as in FIG.

  In FIG. 13 described above, the 1a image line (2b) constituting the pattern portion (A1) is arranged below the center (L1) of the lens that is the focal point of the lenticular lens that is the discriminator (F). By superimposing, the pattern portion (A1) was made visible. Therefore, as shown in FIG. 14C, the overlapping is performed so that the 1b image line (2a) constituting the background portion (A2) is arranged below the center (L1) of the lens which is the focal point of the lenticular lens. In such a case, it appears to the observer that the 1b image line (2a) constituting the background portion (A2) is expanded in the first direction (X1).

  Therefore, as shown in FIG. 14A, the background portion (A2) of the first latent image (A) is visible.

  As described above, in the formed body (S) of the present invention, the visible image (C) and the second latent image (B) are changed due to the change in the observation angle by forming a thick image line in a multilayer structure. It is visually recognized and further changed from the visible image (C) to the first latent image (A) by being overlapped with the discriminating tool (F). The first latent image (A), the second latent image (B), and the visible image (C) can have different colors and shapes by having a multi-layer structure. Are better.

  Therefore, the formed body (S) of the present invention can not only easily determine the authenticity of the formed body (S) by visual inspection and the discriminating tool (F), but also has a design property that is higher than conventional ones. The formed body (S) is provided with an excellent latent image.

  In addition, the formed body (S) of the present invention can be composed of only the first latent image (A) and the second latent image (B) without having the visible image (C). is there. At that time, as shown in FIG. 15, the first latent image (A) and the second latent image (B) are stacked.

  Further, as shown in FIG. 16, the first latent image (A) is visible in the formed body (S) consisting of only two latent image images as shown in FIG. Since the image (A) is an image in which meaningful information appears when the discriminating tool is superimposed, a solid image with a uniform density is visually recognized by the naked eye. Hereinafter, the formed body (S) of the present invention will be described as a formed body (S) composed of three images: a visible image (C), a first latent image (A), and a second latent image (B). To do.

  In addition, it is also possible for at least one color material among the color materials forming the image lines (2, 3, 4) described above to include one functional material. The functional material is a material having a known functionality such as a fluorescent pigment, a phosphorescent pigment, a phosphorescent pigment, a photochromic pigment, an infrared reflection, fluorescent light emission, magnetism, or a material having an action by various electron beams. When the functional material is included, various functionalities can be added to the formed body (S) in addition to the effect of changing the image by changing the observation angle.

  For example, when a fluorescent material is added to the second image line (3), the visible image (C) is visually recognized from the first observation angle (E1), and the second latent image from the second observation angle (E2). When the image image (B) is visually recognized, the first latent image (A) is visually recognized by the discriminator (F), and further irradiated with ultraviolet wavelength light, the emitted second latent image (B) Is visible.

  As another configuration, in the case where a magnetic material is added to the second color material forming the second image line (3), in addition to the authenticity determination based on the change of the observation angle, the reading having a known magnetic head is performed. By reading the magnetic intensity with the apparatus, it is possible to determine the authenticity of the formed body (S) by mechanical reading.

  Conventional anti-counterfeit prints also use printed materials to which the functionality of the functional material is added by using a color material containing a functional material. There was a problem that the functional material could not be contained in a large amount and the functional effect of the functional material could not be fully exhibited.

  However, since the formed body (S) of the present invention is composed of image lines having swells, the color material forming each image line (2, 3, 4) sufficiently contains a functional material. It becomes possible. Therefore, authenticity determination can be performed by secondary authentication corresponding to the functionality of the functional material.

  Furthermore, since the formed body (S) of the present invention has a laminated structure, it is possible to include different functional materials in the color materials constituting each layer, and the formed body (S) with improved anti-counterfeit effect. It becomes.

  The visible image (C) described above is a binary image, but can also be a gradation image. Next, an example in which the visible image (C) is a gradation image will be described. FIG. 17A is a schematic diagram when the formed body (S) is observed from the first observation angle (E1) which is the front surface with respect to the base material (1), and FIG. FIG. 17A is an enlarged view of a part of the region (P) in FIG. 17A, and FIG. 17C is a cross-sectional view taken along the line XX ′ in FIG.

  In the visible image (C) described above with reference to FIG. 9, the image line width of the third image line (4) constituting the visible image (C) is constant. However, as shown in FIG. 17B, the plurality of third image lines (4) have different image line widths (W3) in at least two places within one third image line (4). By having a plurality of lines, a partial change occurs in the line area ratio of the visible image (C) made up of the plurality of third lines (4), so that an arbitrary floor can be added to the visible image (C). It is possible to add a toned image.

  For example, when the image line width (W3) is increased, the image area ratio of the visible image (C) is increased, and when the image line width (W3) is decreased, the image line of the visible image (C) is increased. The area ratio becomes low.

  In FIG. 17, gradation is given to the shape of the fish which is a visible image (C). Even in the case of providing gradation, the color material for forming the third image line (4) is the same as the color material described above, and thus the description thereof is omitted. Further, in the image line width (W3), the stacked first image line (2) and second image line (3) are arranged in the above-described range without overlapping.

  Next, a method of creating image data used when creating the above-described formed body (S) will be described. In addition, as demonstrated using FIG.15 and FIG.16, the formation body (S) of this invention does not have a visible image (C), but a 1st latent image image (A) and a 2nd latent image. Although it is possible to constitute only the image (B), a formed body (S) consisting of three images of a visible image (C), a first latent image (A) and a second latent image (B). ) Will be described below as a method for creating image data.

  FIG. 18 shows the forming device (M) of the formed body (S). The creation device (M) includes at least an input unit (U1), an editing unit (U2), and a storage unit (U3).

  The input unit (U1) is a means for acquiring data necessary for creating the formed body (S) and giving it to the editing unit (U2).

  The editing unit (U2) stores the given data in the storage unit (U3), performs all of arithmetic processing, image processing, and the like necessary for creating the formed body (S), and outputs the obtained results to the printing unit. To (U4).

  The storage unit (U3) is a means for storing various data necessary for the calculation of the editing unit (U2) and the calculation results thereof as data necessary for forming the formed body (S).

  The stroke data used when creating the formed body (S) can be created by the input unit (U1), the editing unit (U2), and the storage unit (U3) described above. In order to print the formed body (S), it is possible to further include a printing unit (U4), a communication interface (U5), and a display body (U6).

  The printing unit (U4) is means for printing the data given from the editing unit (U2) to obtain the formed body (S). For the printing unit (U4), a plateless digital printing apparatus such as a laser printer, an ink jet printer, a film setter, or a plate setter capable of printing an image line having a bulge is used. By not using the printing plate, not only the plate making process is eliminated, but the details will be described later, but when forming a plurality of formed bodies (S), images formed for each formed body (S) are different images. It is possible to perform variable printing.

  Conventionally, when creating a printed matter in which a latent image appears by changing the observation angle, it has been created by previously imparting irregularities to the substrate (1). Therefore, it has been essential to use the printing unit (U4) capable of printing without damaging the unevenness of the substrate (1). On the other hand, in the formed body (S) obtained by the production method of the present invention, the unevenness is formed by a pile of ink. Therefore, if it is possible to print an image line having a rise, the printing unit (U4) can be a printing unit (U4) that performs a known printing method.

  The communication interface (U5) connects a computer terminal (not shown) and the editing unit (U2), and transfers information between the computer terminal and the editing unit (U2) as necessary. For example, with the communication interface (U5), it is possible to obtain various data necessary for creating the formation (S) such as images and texts from an external database server registered in advance.

  The display unit (U6) is a means for displaying information necessary for the creator, such as input data, calculation results, data necessary for creating the formed body (S), input conditions, commands, etc., for example, CRT, At least one liquid crystal display or the like is provided.

  A method of creating the formed body (S) according to the present embodiment using the creating apparatus (M) of FIG. 18 will be described using the flowchart of FIG. 19 showing the procedure.

  First, as the image data acquisition step f1, the pattern portion image data (iA) that is the original image of the first latent image (A) and the second latent image that is the original image of the second latent image (B). Image image data and visible image data that is an original image of the visible image (C) are respectively created.

  In the present embodiment, all the data is stored in the storage unit (U3). However, in order to explain in detail, the data is schematically shown in the drawings below.

  First, as f1-1, in order to acquire the image data of the first latent image (A), the pattern portion image data (iA) that is the original image of the first latent image (A) is edited ( The pattern part image data (iA) created by U2) or created and / or acquired in advance is acquired from the input unit (U1) and stored in the storage unit (U3) via the editing unit (U2).

  As described above, the first latent image (A) is an image formed by being superimposed on the visible image (C), and is an image that can be visually recognized by the determination tool (F).

  In the present embodiment, when the case of acquisition by the input unit (U1) and the case of creation by the editing unit (U2) are described together, the input unit (U1) and the editing unit (U2) are used. Will be described.

  If the original image acquired by the input unit (U1) is not binary image data or outline graphic data (hereinafter referred to as “digital data”) using a bitmap, it is necessary to convert it into digital data. The unit (U2) needs to further include data conversion means for converting the original image into digital data.

  Therefore, the input unit (U1) converts the acquired original image into digital data and the input unit (U1) that acquires the pattern image data (iA) that is the original image of the first latent image (A). It is preferably a reading device such as a scanner provided with data conversion means in one device or an imaging device such as a digital camera, a video camera, or a portable terminal. By using the input unit (U1) provided with data conversion means, it is possible to acquire an image and convert it into digital data at a time.

  When image data created and / or acquired in advance is used as the pattern portion image data (iA), the input unit (U1) is a CD- that has already recorded the original image created and / or acquired as digital data. Input / output devices such as an MO drive, a CD-ROM drive, an FD drive, and an image card reader that acquire digital data from an information recording medium such as a ROM, FD, or USB memory may be used.

  In this case, as described above, since the original image has already been converted into digital data, it is not necessary to go through the editing unit (U2). Therefore, after obtaining by the input unit (U1), it is stored in the storage unit (U3) without going through the editing unit (U2).

  Pixels in image data are points that are arranged in a grid pattern to form image data, and have information about color as numerical values. The image format for forming an image with pixels is not limited as long as the image can be formed with pixels such as TIFF format and BMP format. In any creation or acquisition method, the image data stored in the storage unit (U3) is composed of a plurality of pixels, but is composed of a plurality of lines on the output.

  Next, in order to obtain image data of the second latent image (B) as f1-2, the second latent image data that is the original image of the second latent image (B) is edited. (U2) or externally via the communication interface (U5), acquired as second latent image data from the input unit (U1), and stored in the storage unit (U3) via the editing unit (U2). Store. The stored second latent image data consists of a plurality of pixels.

  As described above, the second latent image (B) is a symbol that can be visually recognized from the second observation angle (E2) with respect to the base material (1).

  Next, in order to obtain the image data of the visible image (C) as f1-3, the visible image data that is the original image of the visible image (C) is created by the editing unit (U2) or communicated from the outside. It is acquired from the input unit (U1) as visible image data through the interface (U5) and stored in the storage unit (U3) through the editing unit (U2). The stored visible image data is composed of a plurality of pixels.

  As described above, the visible image (C) is a symbol that is visible when observed from the first observation angle (E1) with respect to the substrate (1). As shown in FIG. 17, when the visible image is a gradation image, the visible image data that is the gradation image is acquired in f1-3. The image data acquisition step f1 has been described in the order of f1-1, f1-2, and f1-3. However, the image acquisition order is an example, and the order of acquiring each image data is not particularly limited. Absent.

  Next, as the basic line data creation step f2, the position coordinates, the pitch, and the arrangement direction are set with respect to the line-shaped image line serving as the reference of the image line constituting the first latent image (A), Basic line data is created by the input unit (U1) or the editing unit (U2). The created basic line data is stored in the storage unit (U3).

  First, position coordinates, a pitch, and an arrangement direction are set with respect to a line-shaped image line serving as a reference of the image line constituting the first latent image (A).

  As described above with reference to FIG. 3, the first latent image (A) is different in the phase of a part of the plurality of first image lines (2), and thus the first image line (2b). And a background part (A2) consisting of the 1b image line (2a). Since the first latent image (A) is configured based on the first image line (2), there is only one reference image line. Therefore, the first image line (2) is set as the reference image line.

  First, as f2-1, a position coordinate, a pitch, and an arrangement direction are set with respect to a line-shaped image line serving as a reference of the image line constituting the first latent image (A).

  The first pitch (D1), which is the pitch of the first image line (2), takes into account the output method on the substrate (1) and the image line width (W1) of the first image line (2). These are set as appropriate within the range described above with reference to FIG. The arrangement direction of the first image line (2) is set to an arbitrary direction so that the line-shaped image lines are parallel to each other.

  FIG. 20 is a schematic diagram showing basic line data (L1), which is line data of a line-shaped image line that is a reference of the image line constituting the first latent image (A).

  As described above, the first latent image (A) is an image formed by being superimposed on the visible image (C), and is an image that can be visually recognized by the determination tool (F). As shown in FIG. 1, when the image is observed from the first observation angle (E1), the image line constituting the second latent image (B) is concealed by the first latent image (A). When the image is observed from the second observation angle (E2), the image line constituting the visible image (C) becomes the blind spot of the first latent image (A), so that an image that can be visually recognized is obtained. Change.

  Therefore, in order to hide the visible image (C) and the second latent image (B) arranged in the same area, the first latent image (A) is composed of visible line data (L1). The image data is larger than the second latent image data.

  For example, when the size of the visible image data (vertical × horizontal) is 500 pixels × 1400 pixels and the size of the second latent image data is 600 pixels × 1300 pixels, the large image data is the basic line data ( The size of L1) is set to be larger than the number of pixels of the visible image data and the second latent image data both vertically and horizontally. In the case of the above-described numerical values, the size of the basic line data (L1) is set larger than 600 pixels in the vertical direction and larger than 1400 pixels in the horizontal direction.

  In FIG. 20, the basic line data (L1) is a rectangular figure. However, the basic line data (L1) is not limited to this, as long as the image data is larger than the visible image data and the second latent image data. Is possible. Needless to say, the image line constituting the basic line data (L1) is not limited to the linear image line shown in FIG. 20, and various image lines shown in FIG. 7 can be used. .

  At least three points are set as reference points in the basic line data with respect to the line-shaped image line that is the reference of the image line constituting the first image line (2). In FIG. 20, among the four corners of the basic line data (L1), three points (P1, P2, P3) are set as reference points. Since the basic line data is composed of a plurality of pixels, a point refers to a single pixel.

  In the basic line data (L1), first, the first reference point (P1) is set as the coordinates of the zero point (0, 0), and then the X1 direction from the first reference point (P1) The point at the distance is set as the second reference point (P2), and further, the point at the distance Y1 from the first reference point (P1) in the Y direction is set as the third reference point (P3). .

  Thus, P1, P2, and P3 are set as reference points in the basic line data (L1). Next, position coordinates that are unique position information indicating the distance to the zero point (0, 0) are set for a plurality of pixels constituting the basic line data (L1).

  Note that a general image format such as the TIFF format, JPEG format, or BMP format has a characteristic that pixels are always arranged in parallel along two axial directions perpendicular to each other in the vertical and horizontal directions. Therefore, when all the pixels constituting each image data have the characteristic that they are always arranged in parallel along two orthogonal vertical and horizontal axis directions, the vertical and horizontal directions of each image data are self-explanatory, and rotation is performed. Since there is no need to consider, only one reference point is required. Hereinafter, the present invention will be described as a configuration in which the reference line data has three reference points.

  Although the basic line data creation step f2 has been described after the image data acquisition step f1, this creation order is merely an example, and either f1 or f2 may be performed first.

  Next, as the first latent image data creation step f3, the editing unit (U2) converts the basic line data into the pattern portion (A1), the background portion (A2), and the contour based on the pattern portion data (A1i). First latent image data divided into parts (A3) is created. The created first latent image data is stored in the storage unit (U3).

  As described above with reference to FIG. 3, the first latent image (A) is different in the phase of a part of the plurality of first image lines (2), and thus the first image line (2b). The pattern portion (A1) is composed of a background portion (A2) composed of a 1b image line (2a) and a contour portion (A3) composed of a 1c image line (2c).

Therefore, from the basic line data consisting of one image line, the image data of the 1a image line (2b) constituting the pattern portion (A1) and the 1b image line (2a) forming the background portion (A2). And the image data of the contour image line (2c) constituting the contour area (A3) are created.

  FIG. 21 is a schematic diagram showing a first latent image data creation step. First, as shown in FIG. 21A, the basic line data (L1) and the pattern portion image data (iA) are overlapped by the editing unit (U2).

  Next, in the editing unit (U2), as shown in FIG. 21 (b), the phase of a part of the basic line data (L1) overlapping the pattern portion image data (iA) is set in the first direction (X1). The pattern portion data (A1i) and the background portion data (A2i) are divided.

  The line data of the 1a line (2b) constituting the pattern part data (A1i) and the line data of the 1b line (2a) constituting the background part data (A2i) are shown in FIG. ) In the outline of the pattern portion data (A1i) indicated by the predetermined areas (K1, K2) in the enlarged view of FIG.

  In the portion where the discontinuity of the image line occurs, in order to reduce the density difference between the pattern portion and the background portion when output as the formed body (S), as shown in FIG. In U2), between the image data of the 1a line (2b) constituting the pattern data (A1i) and the image data of the 1b image line (2a) constituting the background data (A2i). By arranging the image data (2ci) of the contour image (2c), the first latent image data (iA) is obtained.

  The line width of the line drawing data (2ci) of the outline line (2c) is set to the same line width as that of the basic line data (L1).

  In order to generate the contour portion (A3), the image line data (2ci) of the contour image line (2c) is the first 1b constituting the background portion data (A2i) within the predetermined area (K1, K2). It is arranged at a position that is not adjacent to each piece of line data constituting the pattern portion data (A1i) and the background portion data (A2i) with a line area ratio of about half of the line data of the line (2a).

  Next, as the mask processing step f4, the editing unit (U2) superimposes the first latent image data (iA), the second latent image data and the visible image data, which are other image data, After removing the first latent image data (iA) that does not overlap with each image data, mask image data is created. The created mask data is stored in the storage unit (U3).

  FIG. 22 is a schematic diagram showing a mask processing step in the second latent image data (iB). First, as f4-1, the first latent image data (iA) shown in FIG. 22A and the second latent image data (iB) shown in FIG. 22B are overlapped. FIG. 22C shows image data obtained by superimposing the first latent image data (iA) and the second latent image data (iB). In FIG. 22C, the outline of the second latent image data (iB) is indicated by a white line for the sake of schematic illustration.

  Next, the first latent image data (iA) that does not overlap with the second latent image data (iB) is removed to create first mask image data (i1). As described above with reference to FIG. 8, the image line constituting the second latent image (B) matches the shape (design) of the second latent image (B) with the first latent image ( It is necessary to arrange them all on the image line constituting A).

  By performing the process of removing the first latent image data (iA) that does not overlap with the second latent image data (iB), all the image lines constituting the first latent image (A) overlap. The first mask image data (i1) which is image data composed only of the image line is obtained.

  Therefore, since the image line constituting the first latent image (A) and the image line constituting the first mask image data (i1) are all overlapped, when output on the base material (1). The image line constituting the second latent image (B) is on the image line constituting the first latent image (A) in accordance with the shape (design) of the second latent image (B). It is possible to arrange them all in layers.

  As in f4-1, the visible image data is masked as f4-2. Specifically, the first latent image data and the visible image data are overlapped. Next, the first latent image data that does not overlap with the visible image data is removed to create second mask image data. The mask processing step f4 has been described in the order of f4-1 and f4-2. However, this processing order is an example, and the processing order is not particularly limited.

  Next, as the shape setting step f5, the editing unit (U2) uses the first image line (C) that forms the first latent image (A), the second latent image (B), and the visible image (C). 2) The image width and image height of the second image line (3) and the third image line (4) are set by the editing unit (U2). The set data of the line width and line height of each line is stored in the storage unit (U3).

  First, as f5-1, an image line width (W1) and an image line height (h1) of the first image line (2) constituting the first latent image (A) are set. The contour image line (2c) is set to the image line width (W1) and image line height (h1) of the first image line (2).

  FIG. 23A is a schematic diagram showing the first image line (2). Note that FIG. 23 schematically shows the base material (1) in order to explain in detail, but it is actually stored in the storage unit (U3) as digital data. The image line width (W1) and the image line height (h1) are appropriately set within the range described above with reference to FIG.

  Next, as f5-2, an image line width (W2) and an image line height (h2) of the second image line (3) constituting the second latent image (B) are set.

  FIG. 23B is a schematic diagram showing the second image line (3). The image line width (W2) and the image line height (h2) are appropriately set within the range described above with reference to FIG.

  Next, as f5-3, an image line width (W3) and an image line height (h3) of the third image line (4) constituting the visible image (C) are set.

  FIG. 23C is a schematic diagram showing the third image line (4). The image line width (W3) and the image line height (h3) are appropriately set within the range described above with reference to FIG. When the visible image data acquired in f1-3 is gradation image data, the image line width of the third image line (4) is appropriately increased within the range described above with reference to FIG. Or set narrower.

  Next, as a color setting step f6, the color of the color material forming the first image line (2), the second image line (3), and the third image line (4) is selected by the editing unit (U2). Set. The set color data of each image line is stored in the storage unit (U3).

  First, as f6-1, the color of the first color material that forms the first image line (2) shown in FIG.

  The first color material is not particularly limited, but when the third image line (4) is shaded by the first image line (2) when the substrate (1) is tilted and observed, It is desirable to set a color material having a lower brightness than a third color material set to a third image line (4) described later so that the third image line (4) can be sufficiently shielded.

  Next, the color of the second color material that forms the second image line (3) shown in FIG. 23B is set as f6-2.

  The second color material is set to the same color as the first color material that forms the first image line (2) disposed below the second image line (3). When the first color material and the second color material are set to the same color, the first image line (2) and the second image line (3) are distinguished and visually recognized when viewed from the front. The second latent image (B) cannot be identified.

  As other color materials, the second color material is a translucent color material, and the first color material is set to a color material having a lightness lower than that of the second color material. For example, when the first color material that forms the first image line (2) is set to a black color material, the second color material that forms the second image line (3) has transparency. Set to cyan color material. As a result, the cyan second color material having transparency is permeated and absorbed by the black first color material disposed below, and is visible as black from the front.

  The transmission absorption in the present embodiment means that when a color material having a lightness lower than that of the semi-transparent color material is formed under the semi-transparent color material, and the two color materials are viewed from the front, the lightness It means that a translucent color material cannot be identified by a low color material.

  Therefore, the second color material is set to a translucent color material, and the first color material is set to a color material having a lightness lower than that of the second color material. Similarly to the case, when viewed from the front, the first image line (2) and the second image line (3) cannot be distinguished and visually recognized, and the second latent image (B) is identified. It becomes impossible. Hereinafter, the present embodiment will be described assuming that the second color material is set to a translucent color material and the first color material is set to a color material having a lightness lower than that of the second color material.

  Next, as f6-3, the color of the third color material forming the third image line (4) shown in FIG. 23C is set.

  The third color material is not particularly limited, but is desirably set to a color that has low brightness and is clearly distinguishable from the surface color of the substrate (1). For example, when the surface color of the base material (1) to be used is a white color, a cream color or the like with a high brightness, and the third color material is a high brightness color such as yellow, the surface color of the base material (1) and The third color material is not preferable because it is difficult to distinguish.

  The shape setting step f5 has been described in the order of f5-1, f5-2, and f5-3, but this processing order is an example, and the order of setting the shape is not particularly limited. In the color setting step f6, f6-1, f6-2, and f6-3 have been described in this order. However, this processing order is an example, and the order of setting colors is not particularly limited.

  Furthermore, although the color setting step f6 has been described after the shape setting step f5, this setting order may be reversed. For example, after setting the image line width (W1) and image line height (h1) of the first image line (2) constituting the first latent image (A) as f5-1, f6-1. After setting the color of the color material that forms the first image line (2), the shape of the second latent image (B) can be set as f5-2.

  Next, as the image data creation step f7, the first image line (2), the second image line (3), and the third image line, which are the conditions set in the shape setting step f5 and the color setting step f6. Based on the line width, line height, and color material of (4), the editing unit (U2) uses the first line data (i3), the second line data (i4), and the third line. Data (i5) is created. Each created image line data is stored in the storage unit (U3).

  First, as f7-1, based on the line width, line height, and color material of the first line (2) set in f5-1 and f6-1, the first created in f3-1 The first image line data (i3) is created by applying it to the latent image data (iA) and performing an arrangement process at a predetermined position. FIG. 24A is a schematic diagram showing the created first image data (i3). The stroke width, stroke height, and application of color material are created separately by entering the set values each time as setting parameter information for stroke settings or by calling the set values from the setting parameter storage table etc. The first image line data (i3) is stored in the storage unit (U3).

  When forming the formed body (S), in most printing methods, an increase in the line area ratio or the dot area ratio due to dot gain is expected between the formed body (S) and the image line data. Needless to say, when creating line data, it is necessary to set the line area ratio or halftone dot area ratio in advance.

  Next, as f7-2, the first created in f4-2 based on the image line width, image line height, and color material of the second image line (3) set in f5-2 and f6-2. The second image line data (i4) is created by applying the mask image data (i1) and performing an arrangement process at a predetermined position. FIG. 24B is a schematic diagram showing the created second image line data (i4). The created second image data (i4) is stored in the storage unit (U3).

  Finally, as f7-3, the second created in f4-3 based on the image line width, image line height and color material of the third image line (4) set in f5-3 and f6-3. The third image data (i5) is created by applying the mask image data (i2) and performing an arrangement process at a predetermined position. FIG. 24C is a schematic diagram showing the generated third image data (i5). The created third image line data (i5) is stored in the storage unit (U3). The image data creation step f7 has been described in order as f7-1, f7-2, and f7-3. However, this processing order is an example, and the order of creating the image data is not particularly limited. .

  Each image line data for producing the formed body (S) obtained by the production method of the present invention is to make it possible to print an image line made of ink having a bulge on the flat substrate (1). Image line data having information on a desired line height is used.

  Therefore, by using each created image line data and outputting it to the base material (1), different latent image images appear by different discrimination methods of overlapping the observation angle and the discrimination tool (F). The formed body (S) can be created by on-demand printing using a digital printing machine.

  In addition, a plurality of image lines having swells are arranged in a stacked manner, and the visible image (C) and the second latent image (B) are changed by using a blind spot generated when the stacked image lines are tilted. And is visually recognized. Therefore, it is necessary for the formed body using the blind spot generated by the conventional uneven shape to form the uneven shape in advance on the base material (1) itself or the base material (1) by intaglio printing or the like. However, since it is not necessary, the user can freely create the image design, shape, color, and the like.

  As described above with reference to FIGS. 15 and 16, the formed body (S) of the present invention does not have the visible image (C), but the first latent image (A) and the second latent image. It is also possible to configure only from the image (B). In that case, it is not necessary to perform the step (fX) of creating the third image line data, which is necessary when creating the visible image (A) shown in FIG. Specifically, it is not necessary to perform the image data acquisition step f1-3, the mask processing step f4-2, the shape setting step f6-3, the color setting step f6-3, and the image line data step f7-3.

  In the formed body (S) having the above-described production method, secondary authentication can be given in addition to the primary authentication of the appearance of the image due to the change in the observation angle. When the secondary authentication is given to the formed body (S), in the color setting step f6, in addition to the color material color setting described above, it is included in the color material forming each image line (2, 3, 4). Set the functional material to be used.

  As described above, the forming method (S) of the present invention allows the user to easily add the desired functionality (secondary authentication) by setting the functional material simultaneously with the color setting. Become.

  In addition, in order to create a desired formed body (S) using each created image line data, after the image data creation step f6, each layer created in f6 in the printing unit (U4) as a layered output step f7 You may further have the step which forms a drawing line on a base material (1) based on drawing line data.

  As the substrate (1), a known printable material such as high-quality paper, coated paper, card, and sheet-like plastic is used. In this invention, an unevenness | corrugation is provided by laminating | stacking multiple color materials which have a swell with respect to a flat base material (1). Therefore, since it is not necessary to give unevenness to the base material (1) in advance by embossing, cleaning, intaglio printing, etc., there is no particular limitation on the base material (1) to be used, and it is designed more than before. And the width of the output machine widens.

  First, the first image line data (i3) is printed on the base material (1) by a digital printing method to form the first image line (2) having a plurality of bulges. The printing method is not particularly limited as long as the first image line (2) can be formed as a high-quality image line.

  Next, the second image line data (i4) is printed on the plurality of first image lines (2) printed on the substrate (1), and the second image line having a plurality of bulges ( 3) is formed. The printing method is the same as that of the first image line (2) described above.

  Finally, the third image data (i5) is printed at a position that does not overlap the first image line (2) and the second image line (3) printed on the base material (1). A formation body (S) is obtained by forming the plurality of third image lines (4).

  In addition, when the first image line (2) and the second image line (3) having a swell do not reach the desired image line height by one printing, the same place is repeated several times until the desired image line height is obtained. Printing is repeated to form an image line.

  The printing method for the formed body (S) of the present invention is preferably on-demand printing. The first latent image (A) that can be visually recognized by the discriminator (F), the second latent image (B), and the visible image that can be visually recognized by a change in the observation angle. (C) can be printed as a different image for each formed body (S). That is, the first latent image (A), the second latent image (B), and the visible image (C) can be handled as variable images.

  Furthermore, it becomes possible to form each image line (2, 3, 4) arranged on the base material (1) by using a different color material for each individual of the formed body (S). As described above, in the formed body (S) of the present embodiment, at least one color material among the color materials forming each image line (2, 3, 4) can include one functional material. It is. Therefore, by being able to form using different color materials, it becomes possible to impart functionality as a variable element to the formed body (S).

  Therefore, by creating with the creating device (M) having the printing unit (U4) which is a plateless digital printing device, an image that can be visually recognized by primary authentication of tilting, secondary authentication of functionality, and a discriminator ( An image that can be visually recognized by three authentication methods called secondary authentication, which is different from the functionality F), can be applied to one formed body (S) as a variable element.

  When the formed body (S) is created using the visible image (C), the first latent image (A), and the second latent image (B) as variable images, the image data acquisition step f1 Among the plurality of visible image data, the plurality of first latent image data (iA) and the plurality of second latent image data, at least two kinds of different image data in at least one type of image data, After being created by the input unit (U1) or the editing unit (U2), it is stored in the storage unit (U3).

  Further, when the functionality is a variable element, in the color setting step f6, in addition to the color setting described above, a functional material to be included in the color material forming each image line (3, 4, 6), A different functional material is set for each of the plurality of formed bodies (S). In addition, when setting for every some formation body (S), in each image in a formation body (S), a different functional material is set in at least 1 type of image.

  When forming the formed body (S) using each image as a variable image, the user can change from the plurality of image data stored in the storage unit (U3) in the image data acquisition step f1 before the lamination output step f7. It further has a data selection step f7.5 for selecting desired image data to be an image.

  In the stacking output step f8, each line data created in the line data creation step f7 is converted into different line data from the printing unit (U4) based on the desired image data selected in the data selection step f7.5. Output. The created plurality of formed bodies (S) are formed bodies (S) to which a desired image is given as variable information.

  For example, when three formed bodies (S) are created and the first latent image data (iA) of each image data is a variable image, five different image data are used as the first latent image data. After being created by the input unit (U1) or the editing unit (U2), it is stored in the storage unit (U3).

  Next, in the data selection step f7.5, the user selects a desired first latent image to be a variable image from among the five first latent image data stored in the storage unit (U3) in the image data acquisition step f1. Select three image data.

  Finally, in the layered output step f8, the first image line data created in the image line data creation step f7-1 is based on the three first latent image data selected in the data selection step f7.5.
