Description

  The present invention relates to a formed body applied to printed matter that needs to prevent counterfeiting and alteration of banknotes, postal tickets, passports, stock certificates, securities, pass tickets, credit cards, and the like.

  Conventionally, in order to prevent forgery or alteration using a copying machine or a scanner, there are those using holograms or optically changing ink. However, since these are very expensive, there is a problem that it is expensive to manufacture in large quantities. Therefore, in order to manufacture at low cost, use halftone dots of different sizes, and make one half a dot that can be recognized by a copier and the other half as a halftone dot that cannot be recognized. There are technologies that are possible. In the present situation, the forgery or alteration can be made precisely by the development of copying technology such as the resolution of a scanner or the like and the high-quality printing by a printer. Therefore, embossing is applied to the base material to give a concavo-convex structure, and the image of the valley is not recognized by changing the observation angle by printing an image on the ridge and valley of the concavo-convex structure. (For example, refer to Patent Document 1). In addition, there is one that obtains the same effect as embossing by printing raised ink of the same color as the base material to give the base material a concavo-convex structure and printing on the top of the base line. (For example, refer to Patent Document 2). Further, there is a lenticular as a technique for selectively recognizing an image using a lens effect. The lenticular can obtain a 3D effect and an image switching effect by selecting and recognizing the image printed on the lower part of the lens. It is widely used for advertising media in the market. Furthermore, as a method for producing a lens on the surface of a substrate, there is a method for producing a prism lens using an ultraviolet curable transparent screen ink (see, for example, Patent Document 3).

JP 2002-19255 A (page 7, FIG. 3) Patent 2600094 (5th page, FIG. 4) Japanese Patent Laid-Open No. 10-300904 (6th page, FIG. 4)

  However, the latent image display medium described in Japanese Patent Laid-Open No. 2002-19255 described above has a concavo-convex structure directly on the base material, and has a concavo-convex degree that allows the latent image display medium to be recognized by fine paper having a thickness of about 100 μm. When the structure is provided, the embossed trace remains on the back surface, which not only impairs the aesthetic appearance of the product, but also has a high possibility of being counterfeited or altered by analyzing the embossed trace. In addition, the quality of high-quality paper, etc., decreases only when it is embossed, and in order to prevent this, if embossing is applied to the entire surface using intaglio printing pressure, it will not match with the printed matter that has been printed first. It becomes very difficult.

  The latent image printed matter for preventing counterfeiting described in Japanese Patent No. 2600094 gives a latent image pattern by printing a raised line with ink of the same color as the base material and printing a straight line on the raised ink. ing. It is difficult to print a precise straight line on top of the raised ink with high accuracy. The raised ink convexity has good ink setting (adhesion), but the concave ink has poor ink setting. Become. Furthermore, the ink used for the raised ink in Japanese Patent No. 2600094 is limited to the same color as the base material.

  In addition, the lenticular that is a known technique continuously arranges the concave and convex lenses without gaps, so that no message image is given to the lens part, and the image below the lens is selected and recognized, An image cannot be recognized unless an image is placed below the lens. Further, in the lenticular, an image always appears and a latent image cannot be added.

  Further, as a method for manufacturing a prism lens (Japanese Patent Laid-Open No. 10-300904), there is a method in which a lens effect is imparted on a base material using a transparent screen ink. The purpose is to make them recognize.

  According to the present invention, a message is formed on the first image printed on the substrate and the second image printed thereon with a transparent or translucent material, and a background is formed on the third image. The second and third drawing lines are parallel to each other and are shifted in pitch only, and the first drawing line and the second and third drawing lines have the same pitch and are parallel to each other. In addition, when the second and third image lines are printed with a swelled transparent or translucent material, the second and third image lines are observed from directly above by the lens effect (light refraction and diffraction). In this case, the message is not recognized, and the message and the background become apparent by changing the observation angle, so that a copy cannot be made using a copier or a scanner.

  Even when there is no background of the third drawing line and only the message of the second drawing line is formed, the message becomes obvious. In this case, the background is the substrate or the color printed on the substrate.

  In addition, by providing a transparent or translucent layer between the raised transparent or translucent material consisting of the first image line and the second and third image lines printed on the base material, the difference was further increased. It becomes possible to recognize the message by the observation angle.

  By forming a message when the line width is different or the line is shifted in part of the first line, a density difference due to the line width difference is visually recognized when the formed body is observed from directly above. Thus, the latent image pattern can appear by tilting the formed body.

  Further, in the second and third image lines, when the arrangement angle of either the message or the background is not parallel to the first image line, for example, the first image line is the three primary colors. When the red line, yellow line, and blue line are at 0 degrees (horizontal), when the second line message is arranged at 0 degrees and the background of the third line is 5 degrees, the viewing angle is tilted. Sometimes rainbow colors are mixed, and it is possible to obtain a forgery prevention effect.

  The forgery prevention formed body of the present invention is not only a formed body that needs to prevent counterfeiting or alteration of banknotes, postal tickets, passports, stock certificates, securities, coupons, cards, etc., but also the authenticity of a brand called brand protection. In addition to discrimination, it can be used for tags for assuring quality, and it can also be used for general printed materials that are called greeting cards such as Christmas cards and gift message cards.

  Next, an embodiment of a forgery prevention formed body according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a basic configuration of a first image line having a non-image line portion in the present invention. 2 is a cross-sectional view taken along line AA ′ in FIG. Further, a to c are enlarged views of the overlapping state of the first image line 2 and the relief patterns of the second and third image lines 3. In a, a relief pattern of the second and third image lines 3 is printed on the first image line 2, and in b, the second and third image lines straddle the first image line 2 and the non-image area portion 4. The relief pattern of the image line 3 is printed, and c shows a state in which the relief patterns of the second and third image lines 3 are printed on the non-image area 4. Although any state can constitute the present invention, it is more preferable that the second image line is in the state a and the third image line is in the state c. Note that the second and third image lines 3 are preferably configured with a pitch m times the pitch of the first image line 2, and in this case m is a number of 0 or more, but more preferable. Is an integer of 1 or more.

  FIG. 3 is a diagram for explaining the basic principle of FIG. 1 in the present invention. When the formation is observed from directly above, the second and third image lines 3 are hardly recognized, and only the first image line 2 is observed, and the second and third image lines 3 are changed by changing the observation angle. Due to the lens effect of the transparent or semi-transparent ink, the reflected light from the first image line 2 is refracted when passing through the ink in the second and third image lines 3, as if the second and third It is recognized as appearing on the ink surface of the image line 3. In a, since the first and second image lines are printed with one second and third image line, when the formed body is observed obliquely, the second and third lines are bordered by the arcuate vertex of the ink. The first image line 2 below the image line 3 is recognized by being refracted inside the ink. In b, the second and third image lines 3 are printed across the non-image area 4 and the first image line 2, and in this case, the color of the substrate is visible when observed from the opposite side of the broken line portion. Is done. In c, the color of the non-image portion 4 is recognized.

  FIG. 4 is a diagram showing the state of the image lines used for the first image line, the second image line, and the third image line. a is a solid line, b and c are dotted lines, and d is a dotted line, indicating that the line spacing is discontinuous. Although e is a wavy line, it is preferable that the wave has a small magnitude or amplitude. In this figure, a sine wave is imitated, but a rectangular wave or the like can also be used, but a straight line as shown in a is preferable. f, g, and h are branched from one line, and a further forgery prevention effect can be obtained by partially using such a branched line. f is a state in which the branched line is separated without touching, and g is in contact with the branched line compared with f. h has three branched lines instead of two. It is also possible to apply dotted lines such as b, c, d to branch lines. In addition, i is a micro character (a micro character, which is a well-known technique for preventing counterfeiting, such as a small character of about 100 μm to 1000 μm, a technology that makes the character crushed and unreadable when copying such as copying or scanning). It is also possible to configure all the lines and a part of the lines.

  FIG. 5 is a diagram showing a state in which the image lines shown in FIG. 4 are used in combination. a is a combination of FIG. 4 (a), which is a solid line, and FIG. 4 (b), which is a dotted line. As for b, FIG. 4 (a) of a solid line and FIG. 4 (e) of a wavy line are combined. c is a state branched from one line to two, and is the same as FIG. 4 (f) or FIG. 4 (g). d is a solid line in FIG. 4A and the branched line is a dotted line, and is a combination of FIG. 4H and FIG. 4B or FIG. 4C. e is a combination of FIG. 4 (a), which is a solid line, and FIG. 4 (i), which is a minute character. As for f, FIG.4 (b) of a dotted line and FIG.4 (i) of a minute character are combined. g indicates a state where the dotted line of f is divided, and h indicates a combination of the states of c and d. It is possible to apply the line shapes from a to h to some or all of the first, second, and third lines, and the lines are visually observed (a state that is about 30 cm away from the observation object with the naked eye). The effect of the present invention can be obtained in any shape as long as the shape can be recognized, but a solid line as shown in FIG. 4A is more preferable.

  FIG. 6 is a partially enlarged view of the state of the lines used for the first image line, the second image line, and the third image line, as in FIGS. 4 and 5. In a, a solid line shown in FIG. 4A is used for the message 6 in the second image line, and a minute character shown in FIG. 4I is used for the background 7 in the third image line. It is a figure which shows the case where a seed is used. In this case, all line types including (a) to (i) shown in FIG. 4 and (a) to (h) shown in FIG. 5 can be used. In b, c, d, and e, the first, second, and third lines are arranged with different line types, and some of the lines are shown in FIGS. 5A to 5H. It becomes the same as the state. For the first, second, and third image lines in the present invention, any combination such as the line type shown in FIG. 4 and the image line combination shown in FIG. 5 or the image line arrangement shown in FIG. 6 can be used. is there.

  FIG. 7 is a diagram showing the situation of the message 6 in the second image line and the background line 7 in the third image line, and the diagrams from a to e expand the overlapping state of the message and the background image line. It is shown. In a, the message and the background line are separated from each other, in b, the line is shifted, and in c, the message line is thicker than the background line. In d, the message line is thinner than the background line, and in e, the message line is combined with the background line but shifted (relief pattern). The present invention can be configured in any state, and a combination of a to e is possible, but preferably the message and background lines are the same thickness as shown in a, b, and e, and the pitch The ones that are only off are better.

  In addition, when the second and third lines are divided into a message and a background, and the message has a relief pattern with a pitch shifted from that of the background, it is preferable that the relief pattern is raised within the range of the background pitch. That is, in the case of a line pattern with an image line width of 150 μm and a pitch of 300 μm, the pitch deviation interval of the message may be set from 1 μm to 299 μm. Further, it is preferable that the thickness is 100 μm to 200 μm because the visibility is improved.

  FIG. 8 is a diagram showing a configuration when a message image is added on the first image line 2. a is a message image 8 added to a part of the first image line 2 by narrowing the image line width. When the background image line is 150 μm, the message image 8 line is set to 100 μm. Thus, a density difference (in this case, the message becomes lighter than the background) occurs depending on the line width of the line, and the message image can be visually recognized even when observed from directly above. b is a message image added by increasing the line width to a part of the first image line. When the background image line is 100 μm, the message image line is set to 150 μm. A density difference (in this case, the message becomes darker than the background) occurs depending on the line drawing width of the line, and the message image can be visually recognized even when observed from directly above. In order to clearly recognize the difference in the line width at this time, 10 μm or more is necessary, and about 50 μm is preferable. However, if a difference more than necessary such as 1000 μm occurs, it will be difficult to recognize the image when the formed body is tilted.

  FIG. 9 is a plan view showing the first image line 2 in which the base material is concealed, and FIG. 10 is a cross-sectional view taken along the line BB ′ in FIG. Further, a to d are enlarged views of the overlapping state of the first image line 2 and the second and third image lines 3. In a, two second and third lines are printed with respect to two first lines (for example, three 150 μm lines are arranged in the first line to form 450 μm lines). In the case of one pattern, it is desirable that the second and third image lines have a line width of 300 μm and a pitch of 450 μm.) In b, the second and third image lines are per one first image line. One is printed (for example, if the first image line has a line width of 150 μm and a pitch of 300 μm, it is desirable that the second and third image lines also have a line width of 150 μm and a pitch of 300 μm). C In FIG. 2, the second and third image lines are printed across the two first image lines. In d, the second and third image lines are printed thinner than the first image line. It shows the state being done. The present invention can be configured in any state, and a combination of a to d is also possible.

  FIG. 11 is a diagram for explaining the basic principle of FIG. When the formation is observed from directly above, the second and third image lines 3 are hardly recognized, and only the first image line 2 is observed, and the second and third image lines 3 are changed by changing the observation angle. Due to the lens effect of the transparent or translucent ink, the reflected light from the first image line 2 is refracted when passing through the ink inside the second and third image lines, as if the second and third images. It is recognized as appearing on the ink surface of line 3. In a, the second and third image lines are printed by one for the first image line, and the second and third image lines are bordered by the arcuate vertex of the ink (broken line portion). The first image line at the bottom of the ink is recognized by being refracted inside the ink. Moreover, when it observes from the other side of a broken line part, the adjacent 1st image line is visually recognized. In b, since the second and third image lines are printed across the first image line, the first image line is a mixed color (for example, green for blue and yellow, purple for red and blue). Can be visually recognized. In c, since the second and third lines are printed with respect to the first line, if the observation angle is changed, the lower first line can be visually recognized. When viewed from another angle, no other image or color appears.

  FIG. 12 is a diagram showing a configuration when a message image is given to a part of the first image line 2 where the base material is concealed. As in the first image line 2 in FIG. 6, a message image 8 is given by narrowing the image line width of a part of the image line, and a is a message image when the background image line is 150 μm. When the line is set to 100 μm, a density difference (becomes lighter than the background) occurs depending on the line width of the line, and the message image can be visually recognized even when viewed from directly above. b is a message image added by increasing the line width to a part of the first image line. When the background image line is 100 μm, the message image line is set to 150 μm. A density difference (darker than the background) occurs depending on the line width of the line, and the message image can be visually recognized even when observed from directly above. In order to clearly recognize the difference in the line width at this time, 10 μm or more is necessary, and preferably about 50 μm is necessary. However, if a difference more than necessary such as 1000 μm occurs, it will be difficult to recognize the image when the formed body is tilted.

  In FIG. 13, the first image line 2 is printed on the substrate 1, the layer 5 made of transparent or translucent ink is printed on a part or the whole of the first image line 2, and the second and third parts are printed on the part or the whole. It is a figure which shows the formed body which printed the image line 3 of this. a is a layer provided between the first image line 2 and the second and third image lines 3 in FIG. 2, and b is the first image line 2 and the second and third image data in FIG. A layer is provided between the lines 3. By providing this layer, the observation angle can be changed.

  The thickness of the layer is preferably in the range of 1 μm to 300 μm. When the ink height (ink height) of the second and third image lines is 20 μm, the thickness of the layer is more preferably about 10 μm to 100 μm. Although it is possible to perform the process outside this range, when using the lens effect of the ink in the second and third image lines, the lens effect must be set so as not to be impaired. When the thickness of the layer is provided in excess, it becomes difficult to clearly recognize the latent image pattern when the formed body of the present invention is tilted.

  In addition, the layer between the first image line and the second and third image lines can be a transparent or translucent film other than a transparent or translucent ink. In this case, the material is not particularly limited as long as it is a transparent material, and in addition to a general film, a thermocompression-type thin piece or the like can be pasted or laminated. However, it is preferable to configure the first image line, the second image line, and the third image line in consideration of the manufacturing process and cost.

  FIG. 14 is a diagram showing an arrangement state of the second and third drawing lines. a shows a state in which the third image line (background) and the second image line (message) are arranged in parallel. b shows a state in which the messages are arranged with a 0 degree arrangement, and the background arrangement angle (in this figure, about 45 degrees is used to clarify that the arrangement angle is changed). It is a thing. c is a diagram showing the third image line (background) set to 0 degree and the arrangement angle of the second image line (message) changed. Although it is possible to constitute the present invention at any arrangement angle of a, b or c, the parallelism as shown in a is preferable.

  In addition, when the first image line is set to 0 degree, the arrangement angle of the second and third image lines can be changed in the range of 0 degree to 90 degrees, but the effect of the present invention is clearly shown. A range of 0 to 45 degrees is preferred for obtaining. Furthermore, when the decorativeness of the design is taken into consideration, the range of 2 degrees to 10 degrees is more preferable. When the arrangement angle of the first image line and the second and third image lines is changed, a moire phenomenon due to the image lines occurs, and when the first image line is printed in red, blue, yellow, etc. When the colors of the second and third image lines are mixed, it becomes a rainbow shape and the decorativeness is further improved.

  Further, in the case where a layer is provided between the first image line and the second and third image lines as shown in FIG. 13, the same effect can be obtained by changing the arrangement angle of the second and third image lines. It is possible to obtain the effect, and it is also possible to obtain the same effect by changing not only the arrangement angle of the second and third drawing lines but also the arrangement angle of the first drawing line. In this case, the arrangement angles of the first image line and the second and third image lines may be different. However, as described above, the arrangement angle is preferably in the range of 0 to 45 degrees, and more preferably in the range of 2 to 10 degrees.

  In addition, the line width that the first line can be recognized by the transparent or translucent ink of the second and third lines is higher than the height of the ink of the second and third lines (from the surface of the substrate). ) Is in the range of 5 μm to 300 μm, and the line width of the first image line is preferably in the range of 30 μm to 1000 μm. For example, when the ink height of the second and third image lines is 20 μm, The visibility is further improved when the line width of the line is in the range of 100 μm to 350 μm.

  The materials constituting the first image line, the second image line, and the third image line of the present invention include ultraviolet curable ink, electron beam curable ink, ink having both ultraviolet curable and oxidative polymerization functions, oxidative polymerization ink, and solvent evaporation drying. Type ink, two-component reactive ink, etc. can be used, and as the equipment to be produced, not only offset printing, gravure printing, intaglio printing, screen printing, letterpress printing, but also commercially available printers can be used It is. The materials used for the second and third image lines and the layer provided between the first image line and the second and third image lines are UV curable ink, electron beam curable ink, UV curable ink and UV curable ink. An ink having an oxidation polymerization function, an oxidation polymerization ink, a solvent evaporation drying ink, a two-component reaction ink, and the like can be used, but an ultraviolet curable ink is preferably used.

  The printing machine used for the second and third image lines and the layer provided between the first image line and the second and third image lines produced in the present invention is offset printing, gravure printing, intaglio. Printing, screen printing, and the like can be used. However, when a printing machine capable of depositing a transparent or translucent ink from 5 μm to 20 μm or more at a time is preferably printed by an intaglio printing and a screen printing machine. In consideration of the imprinting of the first image line and the second and third image lines, intaglio printing is preferably performed by screen printing because the substrate itself may be stretched by the printing pressure. It can be carried out by using gravure overprinting. In addition, even if printing is performed by screen printing or intaglio printing on a substrate such as high-quality paper that is easily infiltrated with ink, it is difficult to obtain an ink deposit for obtaining the effect of the present invention. Therefore, as a surface treatment of the base material, a colorless material such as varnishing, varnish, or medium is soaked in the base material in advance, and the second and third image lines are printed on the base material.

  As the substrate used in the present invention, any paper can be used. For example, high-quality paper, art paper, coated paper, finely coated paper, recycled paper and the like can be used, but it is preferable to use paper with good smoothness. Other than paper, a base made from petroleum, such as vinyl chloride, pet resin, polyethylene, polystyrene, polypropylene, etc., can be used as long as the ink is fixed. In addition, when a transparent or translucent substrate is used, the first image line is printed on the back surface of the substrate, and the second and third image lines are printed on the surface of the substrate. Similar effects can be obtained. In this case, the substrate itself serves as a layer provided between the first image line and the second and third image lines according to the present invention. Therefore, the thickness of the substrate is preferably in the range of 1 μm to 500 μm.
