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

  FIG. 1 is a plan view of an anti-counterfeit medium (A1) provided with a three-dimensional display formed body (1) according to the present invention. On the base material (2) used for general printing such as paper and plastic cards, and on the base material (2) having glitter such as paper coated with sheet-like aluminum or pearl ink, the store name and Information such as ticket type is given by commonly used inks such as cyan and magenta. The anti-counterfeit medium (A1) includes the three-dimensional display formed body (1) at least partially on the base material (2). As shown in the enlarged view, the stereoscopic display formed body (1) has a virtual image (3) that is viewed stereoscopically when observed from a predetermined angle with respect to the substrate (2).

  FIG. 2 is a plan view showing the three-dimensional display formed body (1). As shown in FIG. 2, the three-dimensional display forming body (1) of the present invention regularly forms a micro arc-shaped image area (7b) having a concave or convex arc-shaped image line (7a) having a glitter property. It has arcuate image line regions (7) arranged in a matrix at a pitch. In the present invention, the matrix form is one in which the minute arc-shaped image area (7b) is regularly arranged. The pitches for arranging the fine arc-shaped image line regions (7b) may be the same or different as long as they are regular pitches, but are preferably arranged at the same pitch. By arranging them at the same pitch, the virtual image (3) is clearly displayed.

  Further, the virtual image (3) composed of the letter “B” is formed by a plurality of arcuate image lines (7a). The plurality of arc-shaped image lines (7a) is one of the original symbol parts of the virtual image (3), and the arc-shaped image lines (7a) of the minute arc-shaped image line region (7b) adjacent in the vertical and horizontal directions. Since they are the closest parts of the original pattern, a virtual image (3) is formed by the moire expansion phenomenon of a plurality of arcuate image lines (7a) having different shapes.

  FIG. 3 is an example showing an arcuate image line region (7). A group of minute arc-shaped image areas (7A) in which a plurality of minute arc-shaped image areas (7b) having an arc-shaped image line (7a) are arranged in the first direction (S1) and the first pitch (P1). Is a plan view showing an arcuate image line region (7) in which a plurality of lines are arranged in the second direction (S2) and the second pitch (P2). The arcuate image line (7a) is one of the parts (5) of the original pattern (4) of the virtual image (3), and the parts (5) are adjacent to each other (5). And the nearest part of the original pattern (4) are sampled and arranged in the adjacent minute arc-shaped image area (7b). The virtual image (3) is formed by a plurality of parts (5) formed by the arcuate image line (7a). In addition, each pitch (P1 and P2) and size which arrange | position the micro arc-shaped image line area | region (7b) which has an arc-shaped image line (7a) are the virtual elements (6a) which produce the stereoscopic display formation body mentioned later. Therefore, for convenience of explanation, the relationship between the arc-shaped image line (7a), the virtual element (6a), and the music image line (8a) will be described together.

  FIG. 4 is an example diagram showing the relationship between the arcuate image line (7a) and the virtual element (6a). As shown in FIG. 4, the virtual area (6) is a virtual element of the character “B” having the same shape as the original pattern of the virtual image (3), which has a width (W1) and a vertical width (W2). A virtual element group (6A) in which a plurality of 6a) are arranged in the first direction (S1) and in the first pitch (P1) is converted into the second direction (S2) and the second pitch (P2). Regularly arranged in multiple numbers. Further, each arc-shaped image line (7a) is arranged in each virtual element (6a). The arcuate image line (7a) arranged in each virtual element (6a) is one of the parts (5) of the original pattern (4) of the virtual image (3). Since the part (5) is a part where the adjacent parts (5) are different from each other in the original design (4) and the nearest part of the original design (4), the shape of each arc-shaped image line (7a) Is different.

  First, the virtual area (6) formed by the virtual element (6a) and the plurality of virtual elements (6a) will be described. FIG. 5 is an example of the virtual area (6). As shown in FIG. 5, the virtual area (6) is a virtual element (B) having the same shape as the original pattern of the virtual image (3), which has a width (W1) and a vertical width (W2). A virtual element group (6A) in which a plurality of 6a) are arranged in the first direction (S1) and in the first pitch (P1) is converted into the second direction (S2) and the second pitch (P2). Regularly arranged in multiple numbers. A virtual image (3) is formed by the plurality of arc-shaped image lines (7a).

  The shape of the original pattern (4) that forms the virtual image (3) is not particularly limited, and characters, figures, symbols, and the like can be used. The horizontal width (W1) and vertical width (W2) of the virtual element (6a) are each 5 to 1000 μm. The 1st pitch (P1) and 2nd pitch (P2) of a virtual element (6a) are 5-1000 micrometers. When each width (W1 and W2) or each pitch (P1 and P2) is less than 5 μm, it becomes difficult to form an arcuate image line (7a) described later. Moreover, when each width (W1 and W2) or each pitch (P1 and P2) exceeds 1000 micrometers, the visibility at the time of visually recognizing the virtual image (3) falls. Note that the virtual element (6a) in the present invention is a virtual element provided for convenience in order to clarify the relationship of the part (5) described later, and does not actually exist. The first pitch (P1) and the second pitch (P2) may be the same or different.

  FIG. 6 is an example diagram showing the relationship between the arcuate image line (7a) arranged in the virtual element (6a) and the part (5). As shown in FIG. 6 (a), the arc-shaped image line (7a) is one of the parts of the original pattern of the virtual image (3), and the arc-shaped image lines (7a) adjacent in the vertical and horizontal directions are , A portion having a different original design, and a portion closest to the original design. Therefore, the parts (5) are the parts where the adjacent parts (5) are different from each other in the original design (4) and the closest part of the original design (4). Further, the virtual image (3) is formed as a single virtual image (3) due to the moire expansion phenomenon composed of a plurality of parts (5) arranged in the virtual region (6). Each part (5), as shown in FIG. 6 (b), consists of a concave or convex arcuate image line (7a) having brilliant properties, and a plurality of arcuate image lines (7a) are regularly arranged. The virtual image (3) is expressed by the minute arc-shaped image region group (7A) formed in this manner.

  Next, the arcuate image line (7a) will be described. As shown in FIG. 7 (a), the arcuate image line (7a) has the image line width (W3) having the width (W4) and the vertical width (W5), and the curved line (8a). A curved line group (8A) formed by arranging a plurality of lines in one direction (S1) and the third pitch (P3) is formed on each virtual element (6a) as shown in FIG. 7 (b). One curve line (8a) is arranged on at least a part of the line, and the curve line (8a) and the virtual element (6a) are formed only at the overlapping portion.

  The arcuate image line (7a) is appropriately determined in association with the curved image line (8a) forming the virtual image (3) and the virtual element (6a), and the height when the arcuate image line (7a) is convex. Can be appropriately set within a range of 5 to 1000 μm. When the height is 1000 μm or more, it is difficult to produce a concave or convex image line with respect to the base material (2). Moreover, it is preferable that the shape of the arcuate image line (7a) in the depth or height direction has a smooth curved surface such as a saddle shape, a semicircular shape, or a semielliptical shape. When the cross-sectional shape in the depth or height direction of the arcuate image line (7a) is the above-described shape, the bright spot moves smoothly along the curved surface.

  Next, the curved line (8a) forming the arcuate line (7a) will be described. As shown in FIG. 8 (a), the curved line (8a) is a curved line group (8A) formed by arranging in the first direction (S1) and the third pitch (P3). Further, a curved line area (8) regularly arranged in the second direction (S2) and the fourth pitch (P4) is formed. The third pitch (P3) of the curved line (8a) is appropriately set at a different pitch from the first pitch (P1) within the range of 5 to 1000 μm. The fourth pitch (P4) is appropriately set at a different pitch from the second pitch (P1) within a range of 5 to 1000 μm. If the pitches are the same, moire does not appear, so a virtual image cannot be formed. When each pitch (P3, P4) is less than 5 μm, it is difficult to form the arcuate image line (7a) on the substrate (2), which is not preferable. When each pitch (P3, P4) exceeds 1000 μm, a region having no glitter between adjacent arcuate image lines (7a) can be visually recognized. Thereby, in the virtual image (3), there is an area that does not have glitter, and the visibility when the virtual image (3) is viewed three-dimensionally is not preferable. The third pitch (P3) and the fourth pitch (P4) may be the same or different.

  The horizontal width (W4) and the vertical width (W5) of the curved line (8a) are appropriately set within a range of 5 to 3000 μm in consideration of each pitch (P3, P4). When the horizontal width (W4) and the vertical width (W5) are less than 5 μm, it is difficult to form the arcuate image line (7a) on the substrate (2), which is not preferable. When the horizontal width (W4) and the vertical width (W5) are 3000 μm or more, it is necessary to increase the shape of the virtual element (6a) corresponding to the horizontal width (W4) and the vertical width (W5). When the virtual element (6a) is enlarged, it is difficult to stereoscopically view the virtual image (3) due to binocular parallax. The line width (W3) of the curved line (8a) is appropriately set within a range of 5 to 100 μm. When the image line width (W3) is less than 5 μm, the expression of the virtual image (3) is lacking. On the other hand, if it exceeds 100 μm, the virtual image (3) is difficult to stereoscopically view.

  FIG. 8C is an enlarged view of one of the music drawing lines 8a. The curved line (8a) is an arc-shaped line having a start point (U), a vertex (T), and an end point (D).

  Although the details of the stereoscopically viewable image of the present invention will be described later in detail, it can be dynamically visually recognized by changing the observation angle with respect to the base material (2). The reason for dynamically recognizing is that by changing the observation angle with respect to the base material (2), the location where the illumination light of the curved line (8a) having brilliant properties changes with the change in the observation angle. Because. Since the curved line (8a) has an arc shape, the portion of the curved line (8a) that reflects the illumination light continuously changes on the line, so the virtual image (3) continuously moves. Is visually recognized.

  In the curved line (8a), when a straight line connecting the start point (U) and the end point (D) is a reference line (H1), an arcuate curved line (8a) with respect to the reference line (H1) at the start point (U). The angle (θ1) formed by the rising line (H2), which is a tangent line, can be appropriately set within a range of 2 to 90 degrees.

  Between the start point (U) and the end point (D) of the curved line (8a), the incident light from the light source is reflected in different directions within a range where binocular parallax is possible, and thus is visually recognized as a virtual image (3). The When the angle (θ1) formed by the rising line (H2) that is the tangent to the arcuate curved line (8a) with respect to the reference line (H1) at the start point (U) is less than 2 degrees, reflection from the light source Since light is reflected in substantially the same direction, binocular parallax becomes impossible at an appropriate observation distance, which is not preferable.

  On the contrary, when the angle (θ1) formed by the rising line (H2) that is the tangent to the arcuate curved line (8a) with respect to the reference line (H1) at the start point (U) exceeds 90 degrees, Although the incident light is reflected in different directions on the U) side and the end point (D) side, it is not preferable because it falls outside the binocular parallax range.

  Further, at the end point (D), the angle (θ2) formed by the falling line (H3) that is the tangent to the arcuate curved line (8a) with respect to the reference line (H1) is also different from the above-mentioned start point (U) side. For the same reason, it can be appropriately set within a range of 2 to 90 degrees.

  The curve line (8a) is the angle (θ1) formed by the rising line (H2) that is the tangent line of the curve line (8a) to the reference line (H1) and the reference line (H1) at the start point (U). It is preferable that all the composition lines (8a) are the same. In addition, at the end point (D), the angle (θ2) formed by the falling line (H3) that is the tangent line of the reference line (H1) and the drawing line (8a) with respect to the reference line (H1) is also set to all the drawing lines ( In 8a), the same angle is preferable.

  As described above, when the virtual image (3a) is stereoscopically viewed with binocular parallax, the curved line (8a) has an angle (θ1) on the start point (U) side and an angle (θ2) on the end point (D) side. When the angles are the same, the direction of the reflected light from the curve line (8a) is the same in all the curve lines (8a). Therefore, the virtual image (3) can be clearly recognized with the naked eye. On the other hand, as shown in FIG. 8D, when the angle (θ1) on the start point (U) side is different from the angle (θ2) on the end point (D) side, reflection from the curved line (8a) is performed. Variations occur in the direction of light. Thereby, the virtual image (3) is visually recognized as a blurred image, which is not preferable.

  Further, the number of curved lines (8a) forming the arc-shaped line (7a) is not limited to one as shown in FIG. 9 (a), and a plurality of curved lines (8a) having the same period are used. May be formed adjacent to or close to each other. By forming the curved line (8a) having the same period adjacent or close to each other, the amount of light reflected by the curved line (8a) increases, and the virtual image becomes clear. However, the total width of the curved line (8a) forming one arcuate line (7a) needs to be appropriately set within the range of 5 to 100 μm. In addition, the curved line (8a) is not limited to the arc-shaped line illustrated in the example, but a circular line illustrated in FIG. 9B and a wavy line having a certain period illustrated in FIG. 9C. The ellipse shown in FIG. 9D can be used. In addition, when using a circular drawing line for a music drawing line (8a), since the pitch of each virtual element (6a) and each music drawing line (8a) differs, each virtual element (6a) and each music drawing A portion where the line (8a) overlaps gradually shifts, and there is a case where one curved line (8a) overlaps a plurality of adjacent virtual elements (6a). In this case, since noise is generated in the virtual image (3) during observation, each virtual element (6a) and each virtual element (6a) are extracted when all the overlapping portions of the virtual elements (6a) and the curved lines (8a) are extracted. Considering the arrangement pitch of the curved line (8a), only the portion where each virtual element (6a) and each curved line (8a) overlap on a one-to-one basis is extracted to create an arcuate line (7a).

  In the concave or convex arcuate image line (7a) having a glitter property forming the part (5), when the arcuate image line (7a) is convex, the light and dark flip-flop property and / or the color flip-flop property A method of forming a raised image line such as intaglio printing, screen printing, and flexographic printing is used. The light / dark flip-flop property means that the lightness changes due to the change in the observation angle, and the color flip-flop property means that the hue changes due to the change in the observation angle.

  Examples of materials having light and dark flip-flops and / or color flip-flops include common metal powder pigments such as aluminum powder, copper powder, zinc powder, tin powder, brass powder or iron phosphide, and iris pearl. There are inks containing general pearl pigments such as pigments or scaly pigments, and transparent inks or glossy inks.

  Moreover, when forming a concave arcuate image line (7a), it uses for the base material (2) which consists of a material which has a light-dark flip-flop property and / or a color flip-flop property. For materials with light and dark flip-flops and / or color flip-flops, pearl ink and smooth surfaces can be formed in addition to general metal materials such as aluminum or stainless steel and resin materials such as films or plastics. There is a base material (2) to which a coating material or the like is applied. In addition, as a method of forming the base material (2) by deforming it into a convex shape or a concave shape, the base material (2) having a glittering property is deformed by embossing or laser processing. A known processing machine capable of processing is used.

  In addition, even when the base material (2) having no glitter is used, after being deformed into a concave shape or a convex shape, ink having a glitter property is applied to the deformed portion of the base material (2) by printing. By doing so, it is possible to form the arcuate image line (7a). For example, after the base material (2) is deformed into a concave shape or a convex shape by sweeping using a known paper machine, a glossy ink is applied onto the deformed portion by solid printing. An arcuate line is formed. The numerical values such as the shape of the arc-shaped drawing line, drawing line width, height or depth described in the present embodiment are stock certificates, securities, certificate cards, gift certificates, etc., passports, passbooks, driving This is an example of a good numerical value for printed matter that requires anti-counterfeiting such as a license or identification card, and when used for large printed matter such as signs or posters, A numerical value such as the line width, height, or depth may be enlarged in proportion to the size of the intended printed matter to be used.

(Visual principle)
The three-dimensional display formation body (1) of this invention can be visually recognized dynamically by changing the observation angle with respect to a base material (2). The reason for being visually recognized dynamically is that the illumination light of the convex or concave arcuate image line (7a) having brilliancy is generated by changing the observation angle with respect to the substrate (2). This is because the location where the light is reflected changes. By making the part (5) arc-shaped, the location where the illumination light is reflected continuously changes along the arc-shaped image line.

  FIG. 10 is a schematic view showing the visual recognition principle of the three-dimensional display formed body (1) of the present invention. As shown in FIG. 10, the material having the glittering property that forms the arc-shaped image line (7a) reflects incident light from the light source (S). When the arc-shaped image line (7a) is irradiated with light, the reflected light (V1, V2, V3, V4, and V5) is scattered by the arc-shaped image line (7a). Lights scattered in the vicinity interfere with each other, and light is reflected from the arcuate image line (7a) with directionality, with the direction of the plane orthogonal to the arc as the main component (maximum intensity). Although this light has directionality, the light source is white light, and the arc-shaped image line (7a) is not completely scattered, and has a distribution spread over a certain angle range. By irradiating the arc-shaped image line (7a) with light, all the points in the arc-shaped image line (7a) scatter light, but the light scattered at each point (V1, V2, V3, V4 and V5) are radiated with the aforementioned directionality. When the eye is placed at a certain position in space, among the light scattered at various positions on the arc, the positions of points on the circumference of the arc that can deliver scattered light to the eye with the maximum intensity are shown in FIG. become that way.

  FIG. 11 shows the case where the light source and the eyes are in the same direction with respect to the center of the arc, the position of the light source: S, the observation position (eye): G, the center of the arc: O, and the bright spots on the arc: m1, m2. The positional relationship is shown. Bright points that appear bright on the arc: m1 and m2 are points where the plane including the triangle Gom1 and the arc on the substrate intersect. When the eye is moved, the bright spot moves along the arc. A bright spot can shine anywhere on an arc, but only two specific points determined by the aforementioned triangle appear bright. Even if the arc is observed from various places at the same time, only the place corresponding to the position looks bright, so the movement of the bright spot becomes smooth. In addition, it is preferable that the shape of the arcuate image line (7a) in the depth or height direction has a smooth curved surface such as a saddle shape, a semicircular shape, or a semielliptical shape. When the cross-sectional shape in the depth or height direction of the arcuate image line (7a) is the above-described shape, the bright spot moves smoothly along the curved surface.

  As shown in FIG. 12A, since the viewing angle of the left eye (L) of the observer is θL, the reflected light (V1 and V2) within the viewing angle θL is visually recognized by the left eye (L). The On the other hand, the reflected light (V3, V4, and V5) is not visually recognized because it is outside the range of the viewing angle θL. Therefore, as shown in FIG. 12 (b), the arcuate image line (7a) has a glitter property in the left eye (L) of the observer, as shown in FIG. 12 (b). However, the solid line portion on the end point (D) side outside the viewing angle θL is visually recognized as an image line having no glitter.

  On the other hand, since the viewing angle of the right eye (R) of the observer is θR, reflected light (V4 and V5) within the viewing angle θR is visually recognized by the right eye (R). On the other hand, the reflected lights (V1, V2, and V3) are not visually recognized because they are outside the range of the viewing angle θR. Therefore, in the arc-shaped image line (7a), in the right eye (R) of the observer, as shown in FIG. 12 (c), the dotted line portion on the end point (D) side within the viewing angle θR has glitter. However, the solid line portion on the start point (U) side outside the viewing angle θR is visually recognized as an image line having no glitter.

  A portion visually recognized by the arcuate image line (7a) visually recognized by the left eye (L) shown in FIG. 12 (b) and a right eye (R) shown in FIG. 12 (c). The part visually recognized with the glitter of the arcuate image line (7a) has a phase difference on the left and right with respect to the reference line (H1) which is a straight line connecting the start point (U) and the end point (D). Visible as a stroke. Therefore, without forming a plurality of the same images side by side, as shown in FIG. 12D, the observer can visually recognize the arcuate image line (7a) as a three-dimensional image line by binocular parallax.

(Production method)
Next, a system for producing the three-dimensional display formed body (1) according to the present embodiment will be described with reference to FIG. The system includes at least an input unit (100), a processing unit (101), and an output unit (103). The input unit (100) inputs data necessary for producing the three-dimensional display formation body (1) of the present embodiment and gives the data to the processing unit (101). The processing unit (101) performs arithmetic processing, image processing, and the like necessary for producing the stereoscopic display formed body (1) with the image processing apparatus, and gives the obtained result to the output unit (103). The output unit (103) outputs the data given from the processing unit (101) to an external device such as a laser engraving machine or a printing machine (not shown). Note that a storage unit (102) for recording given data and produced data may be included.

  A method of manufacturing the three-dimensional display formation body (1) according to the present embodiment using such a system will be described with reference to FIGS. 14 to 21 showing the procedure. As shown in FIG. 14, the three-dimensional display formed body (1) according to the present invention includes a virtual element manufacturing step (T1), a virtual region manufacturing step (T2), a curved line manufacturing step (T3), It consists of a curved line region production step (T4), a composite region production step (T5), a minute arc-shaped line region group production step (T6), and an arc-shaped line region production step (T7).

In the virtual element production step ( T1 ), data corresponding to the original design is produced based on the data input from the input unit (100), or the virtual element (6a) is produced in the processing unit (101). In the virtual region creating step (T2), a virtual element group (6A) in which a plurality of virtual elements (6a) are regularly arranged in the first direction and the first pitch is arranged in the second direction and the first direction. A plurality of virtual regions (6) arranged at a second pitch that is the same as or different from the first pitch is created in the processing unit (101). In the curved line creation step (T3), data for a curve having a predetermined stroke width is created based on the data input from the input unit (100), or the curved line (8a) is processed in the processing unit (101). ). In the curved line area production step (T4), the curved line group (8A) in which a plurality of curved line lines (8a) are arranged in the first direction and the third pitch is converted into the second direction, and A curved line area (8) regularly arranged in a fourth pitch that is the same as or different from the third pitch is produced in the processing section (101). In the composite area creation step (T5), the virtual area (6) and the curved line area (8) are arranged so that a part of each curved line (8a) overlaps a part of each virtual element (6a). Thus, the synthesis region (9) is created in the processing unit (101). The minute arc-shaped image line area group production step (T6) includes a plurality of arc-shaped image lines (7a) in a portion where each curved line (8a) and each virtual element (6a) overlap from the synthesis area (9). The processing unit (101) creates a small arc-shaped image area group (7A) from which the image is extracted. In the arc-shaped image area production step (T7), the surface of the substrate is convex or concave by the output unit (103) of a laser processing apparatus or a printing machine based on the minute arc-shaped image area group (7A). An arcuate image region (7) having a glitter property is produced.

  Next, each step will be described in detail. As shown in FIG. 15, the virtual element production step (T1) is a virtual region (6a) corresponding to a virtual image produced by the processing unit (101) or inputted from the outside by the input unit (100) ( 6) is input, and the processing unit (101) creates a virtual element (6a) having the same shape as the virtual image having the horizontal width (W1) and the vertical width (W2).

  In the virtual region manufacturing step (T2), as shown in FIG. 16, the virtual element (6a) having the width (W1) and the vertical width (W2) thus produced is processed in the first direction by the processing unit (101). (S1) and a plurality of virtual element groups (6A) arranged at the first pitch (P1) and arranged in a plurality are regularly arranged in the second direction (S2) and the second pitch (P2). The arranged virtual region (6) is set and created by the processing unit (101).

  In the curved line creation step (T3), as shown in FIG. 17A, the curved line (8a) having a circular arc shape or a circular shape is created by the processing unit (101), or the input unit from the outside. A curved line (8a) having an image line width (W3) having a width (W4) and a vertical width (W5) is input by the processing unit (101) by inputting an arcuate or circular curve by (100). Is made.

  In the curved line area production step (T4), as shown in FIG. 17B, the produced curved line (8a) is processed by the processing unit (101) in the first direction (S1) and the third pitch. A curved line area (8) in which a plurality of curved line groups (8A) set by (P3) are regularly arranged in the second direction (S2) and the fourth pitch (P4) is arranged. The setting is made by the processing unit (101). The size of the music stroke line area (8) is preferably the same as or substantially the same as the virtual area (6) described above. When the sizes of the curved line area (8) and the virtual area (6) are the same or substantially the same, by aligning the center of the curved line area (8) with the center of the virtual area (6) as a reference, The synthesis region (9) to be described later can be easily produced.

  As shown in FIG. 18, the composite region creation step (T5) is based on the created virtual region (6) and the curved line region (8), and each composition is formed in a part of each virtual element (6a). The composition area (9) is set by the processing unit (101) by superimposing the curved line area (8) on the virtual area (6) so that a part of the line (8a) overlaps. In addition, as an example of the synthesis region creation step (T5), any at least three points at positions where the virtual region (6) and the curved line region (8) are common are used as reference points in each region. Set to.

  FIG. 19 is a schematic diagram showing respective reference points in the virtual area (6) and the music stroke line area (8). When setting the reference point, arbitrary three points in the virtual region (6) are selected. In the virtual region (6), first, after setting the first reference point (K1), a point at a distance of X1 in the X direction from the first reference point (K1) is set as the second reference point. A point (K2) was set, and a point at a distance Y1 from the first reference point (K1) in the Y direction was set as a third reference point (K3). Thus, K1, K2, and K3 were set as reference points in the virtual region (6). Next, the reference point of the curved line area (8) is set at a position common to the three reference points set in the virtual area (6).

  In the curved line area (8), first, the first reference point (K1 ') is set, and then the first reference point (K1') is moved in the X direction in the same manner as the virtual area (6). , A point at a distance of X1 is set as a second reference point (K2 ′). Further, a point at a distance of Y1 in the Y direction from the first reference point (K1 ′) is taken as a third reference point (K3 ′). The distance between the three reference points in each area is the same. In this way, any three points at positions where the virtual region (6) and the music stroke line region (8) are common are set as the respective reference points.

  When each region has the same size, it is possible to set a reference point at a common position in each region by setting at least three corners among the four corners in each region as reference points.

  As shown in FIG. 20, in the micro arc-shaped image line group production step (T6), each processing line (8a) and each virtual image line are virtualized by the processing unit (101) based on the produced synthesis area (9). Only a plurality of arc-shaped image lines (7a) where the element (6a) overlaps are extracted, and a small arc-shaped image line region group (7A) is produced.

  As shown in FIG. 21, the step (T7) of forming the arc-shaped image area on the substrate is performed on the basis of the produced micro arc-shaped image area group (7A), such as a laser processing apparatus or a printing machine. By (103), an arcuate image line region (7) having a convex or concave glitter is formed on the surface of the substrate.

  Next, an example in which the curve line (8a) is circular will be described. Note that description of the same structure as the above-described manufacturing method is omitted, and only different portions are described. FIG. 22 shows a virtual region (6) produced by arranging a plurality of virtual elements (6a) and a plurality of circular curved lines (8a) by the method shown in the paragraphs (0062) to (0065). It is an example figure of the synthetic | combination area | region (9) formed based on the curved line area | region (8) produced by arranging, and as shown to an enlarged view, one curved line (8a) is two virtual elements ( It has a portion (10) that overlaps 6a). This is because when the curve line (8a) is circular, the pitch between the virtual element (6a) and each curve line (8a) is different, so that each virtual element (6a) and each curve line (8a) have different pitches. The overlapping part gradually shifts, and a part (10) that overlaps the two virtual elements (6a) occurs depending on the size of the circular drawing line. In this case, noise may occur in the virtual image (3) during observation. Therefore, in the minute arc-shaped image line region group production step (T6), from the portion (10) overlapping the two virtual elements (6a), a circle It is desirable to select one arcuate image line (7a) so that there is no virtual element (6a) on which no arcuate image line (7a) is formed. When only one arcuate image line (7a) is extracted from one virtual element (6a), the virtual image (3) becomes clear.

  In the overlapping portion (10), as shown in FIG. 23, two virtual elements (6a-1 and 6a-2) are provided so that there is no curved line (8a) that does not form the arcuate line (7a). The arc-shaped image line (7a) is extracted from the virtual element (6a-1) selected from the two virtual elements (6a-1 and 6a-2) from the part (10) overlapping with By not extracting the arcuate image line (7a) from the virtual element (6a-2), the minute arcuate image region group (7A) is produced. After the extraction, as shown in FIG. 24, the output unit (103) of the laser processing apparatus or the printing machine is used on the basis of the produced minute arc-shaped image region group (7A) by the same means as in the paragraph (0066). Thus, an arcuate image line region (7) having convex or concave glitter is formed on the surface of the substrate (2).

  Next, an example will be described in which the curve line (8a) includes a curve line obtained by mirror-inversion of the arc-shaped image line (the direction of the arc-shaped image line is reversed horizontally or vertically). Note that description of the same structure as the above-described manufacturing method is omitted, and only different portions are described. FIG. 25 shows a virtual region (6) produced by arranging a plurality of virtual elements (6a) by the method shown in the paragraphs (0062) to (0065), and two arc-shaped curved lines (8a- 1 and 8a-2) is an example of a synthetic region (9) formed on the basis of a curved line region (8) produced by arranging a plurality of regions, and as shown in an enlarged view, the synthetic region (9) The first composition line (9a-1) where the first curve line (8a-1) overlaps the virtual element (6a) and the first curve line (8a-1) are formed by mirror inversion. The second composition line (8a-2) has a second composite area (9a-2) overlapping the virtual element (6a).

  As shown in FIG. 26, the first synthesis region (9a-1) and the second synthesis region (9a-2) are formed by the curve line creation step (T3) in the curve stroke region creation step (T4). A first curved line area (8-1) in which the first curved line (8a-1) input or created is arranged in a matrix at a pitch different from that of the virtual element (6a), and the first curved line A second curved line region (8-) in which second curved lines (8a-2) formed by mirror-inversion of the printed line (8a-1) are arranged in a matrix at a pitch different from that of the virtual element (6a). 2) is prepared.

  Next, as shown in FIG. 27, the virtual area (6) and each curved line area (8-1 and 8-2) produced by the method shown in the paragraphs (0062) to (0065) described above are used as the basis. In addition, each curve line area (8-1) on the virtual area (6) so that a part of each curve line (8a-1 and 8a-2) overlaps a part of each virtual element (6a). And 8-2) are overlapped, and the first combined region (9a-1) and the second combined region (9a-2) are set by the processing unit (101). Next, based on the synthesized region (9) thus produced, the processing unit (101) causes the arcuate image line of the portion where each curve line (8a-1 and 8a-2) and each virtual element (6a) overlap. Only a plurality of (7a-1, 7a-2) are extracted, and a minute arc-shaped image line region group (7A) is produced.

  By means similar to paragraph (0066), as shown in FIG. 28, based on the produced minute arc-shaped image area group (7A), the output unit (103) of a laser processing apparatus or a printing machine etc. An arcuate image line region (7) having a convex or concave glitter is formed on the surface of (2).
