Description

 Specification

 Anti-counterfeit printing

 Technical field

 The present invention relates to a forgery-prevention printed matter which is applied to a printed matter which needs to prevent forgery or alteration of banknotes, stock certificates, passports, securities, passports, cards, product tags and the like.

 Background art

 [0002] In printed materials, such as banknotes, stock certificates, passports, securities, passports, cards, and product tags, that need to prevent forgery or falsification, oblique observation is performed by obliquely observing printed materials. As a device that determines the authenticity of an image by changing the appearance or color of an image, a device that produces a latent image using the image configuration of an intaglio print, or a device that changes color using an optically changing ink And the like. As a typical technique in which an image continuously changes when observed in a horizontal direction gradually from a vertical direction with respect to a substrate, holo-dalum is cited.

 [0003] In the case where a latent image is made to appear by using the object configuration of an intaglio printed material, for example, an image portion that becomes a latent image on an intaglio-printed line is composed of a high-level image and an image. The intaglio printing of the object is constituted by an object which is lower than the object which is a latent image. As a result, when the printed matter is observed at different angles, a latent image appears. Further, there is a type in which a latent image is developed due to uniform widths of image lines and different directions. Patent Document 1 is disclosed below as a disclosure of such a technique.

 [0004] Japanese Patent Publication No. 56-19273 (Page 1, Figure 115)

 A multicolor printed matter in which a specific pattern is printed using a pearlescent ink, the specific pattern indicating interference light that changes color depending on the viewing angle, and the color of the pearlescent ink by copying with a color copier Patent Literature 2 discloses a printed matter in which the printed matter is reproduced in different colors that can be visually identified.

 JP-A-9-240133 (pages 1-3, FIG. 1)

However, the printed matter disclosed in Patent Document 1 has a latent image composed of an intaglio image. When a printed material was created by providing a printed pattern on the base of an image to be printed, and when the printed material was observed obliquely, there was a problem that the latent image could not be confirmed. In addition, there was little room for improvement in anti-counterfeit technology. On the other hand, in the printed matter disclosed in Patent Document 2, only a specific pattern is printed with a pearly glossy ink, and the anti-counterfeiting effect is poor and may be easily duplicated, leaving room for improvement. In addition, when observing the base material gradually from the vertical direction to the horizontal direction, a hologram is a typical technique that continuously changes the image. Power holograms are expensive and unsuitable for small-scale production.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Next, with reference to the drawings, a description will be given of a forgery-prevention printed matter according to an embodiment of the present invention. The present invention is not limited to the following embodiments, and various modes can be adopted within the technical scope of the claims.

[0036] A predetermined image C including a first region 2, a second region 3, and a third region 4 on the base material 1 is illustrated. Shown in 1.

 The predetermined image C is printed with glossy ink.

In each of the first area 2, the second area 3, and the third area 4, a line object is formed, and the line object 2a formed in the first region 2 is formed. The arrangement direction of the line objects 3a formed in the second region 3 and the arrangement direction of the line objects 4a formed in the third region 4 are gradually different.

For example, when the arrangement direction of the line objects 2a formed in the first area 2 is 0 degrees, the arrangement direction of the line objects 3a formed in the second area 3 is 45 degrees, The arrangement direction of the line image 4a formed in the region 4 may be 90 °.

In FIG. 1, the force forming the arrangement direction of the line objects 2a to 4a counterclockwise is good even if the arrangement direction of the line objects 2a to 4a is formed clockwise. ,. In addition, the present invention is not limited to the force in which the arrangement direction of the line objects 2a, 3a, and 4a is 0 °, 45 °, and 90 °.

 For example, the condition of the angle of the line 2a, the angle of the line 3a, the angle of the line 4a, or the angle of the line 4a, the angle of the line 3a, and the angle of the line 2a May be satisfied.

 Further, the line drawing 2a, the line drawing 3a, and the line drawing 4a are composed of fine lines with swelling.

 In FIG. 1, the predetermined image C includes three regions, ie, a first region 2, a second region 3, and a third region 4. The number of regions according to the present invention is not particularly limited as long as it is 3 or more. It may have n (n is an integer of 3 or more) regions. Preferably, n of the n regions is an integer of 3 or more and 100 or less.

 The outer shape P in FIG. 1 is formed as a circle. However, the present invention is not limited to a circular shape, and can select an arbitrary shape such as an ellipse, a polygon, a logo mark, or the like. Only the inside of 2, 3, 4) is formed with a line drawing, and the outline P does not have to form a drawing.

FIG. 2 is a cross-sectional view taken along a line AB in FIG. As shown in Fig. 2, line drawing 2a, line drawing The objects of the line 3a and the line object 4a have the height W of the swell.

FIG. 3 shows a state in which the printed matter of FIG. 1 is observed from the vertical direction.

 When the printed material is observed in the vertical direction, the first area 2, the second area 3, and the third area 4 are composed of fine line objects 2a, line objects 3a, and line objects 4a. Is difficult to identify. At the same time, the first area 2, the second area 3, and the third area 4 are printed with glossy ink, and are difficult to confirm under the influence of light due to diffused light. For this reason, the first area 2, the second area 3, and the third area 4 are visually recognized in a state in which it is difficult to distinguish them, and are recognized as areas close to solid.

 When the printed matter according to the present embodiment is viewed from the vertical direction, in order to be recognized as a solid printed matter, the line drawing of the first area 2, the second area 3, and the third area 4 is required. More preferably, the pitch width of each line is 60 zm force, and the range of 2000 xm, and each line width of the line is 30 zm force and the range of 1000 μm is more preferable. The line width of each line of a line is in the range of 120 μm to 400 μm, and the width of each line is 60 μm and the range is 800 μm. preferable. If the object width is smaller than 30 / im, it is difficult to make the image. In addition, the ratio between the width of each object and the width of each non-object is preferably 1: 1.

When the printed matter according to the present embodiment is observed while being gradually tilted from the vertical direction to the horizontal direction, the first region 2, the second region 3, and the third region 4 are formed. Since the arrangement direction of the line objects 2a, 3a, and 4a is different, the amount of specular reflection and diffusion at the line objects (2a, 3a, 4a) that form the respective areas (2, 3, 4) There is a difference in light quantity. As shown in FIG. 4, at a specific observation angle, the amount of reflected light in the third region 4 exceeds the amount of reflected light in the first region 2 and the second region 3, so that the third region 4 becomes apparent. At a deep observation angle, the amount of reflected light in the second region 3 exceeds the amount of reflected light in the first region 2 and the third region 4 as shown in FIG. When the depth is further increased, as shown in FIG. 6, the amount of reflected light in the first region 2 exceeds the amount of reflected light in the second region 3 and the third region 4, so that the first region 2 becomes apparent. When observing gradually from the vertical direction to the horizontal direction in this way, since the arrangement direction of the line drawing in each region is different, the reflected light amount of the line drawing forming each region is different, and the third region has a different reflected light amount. Color in the first area according to the direction Since the color or brightness changes gradually, a predetermined image can be visually recognized with a sense of movement. In the drawing, the color or brightness changes gradually as the third area moves toward the first area. Depending on the observation method, the color or lightness changes as the first area moves toward the third area. The darkness changes gradually and is visually recognized. Further, the above-described effect can be obtained by continuously changing the angle of incident light such as spot light without tilting the printed matter.

 Further, the printed matter according to the present embodiment has a copy preventing effect of a copying machine, an image input device, and the like. This has a copy-preventing effect due to the fact that printing is performed with glossy ink and the relationship between the arrangement direction of the lines and the scanning lines of a copying machine or the like.

 The principle of the visual effect in the present embodiment will be described with reference to FIG.

 For example, when light is applied from the direction of D to a printed material with a swelling image using glossy ink, the amount of light reflected at e and f is smaller than the amount of light reflected from d. When the light irradiation angle is changed, the amount of light reflected from the portion f exceeds the amount of light reflected from the portion d, and the portion f becomes apparent. In this way, using a glossy ink with a mirror surface to create a raised image, and changing the angle of the image, you can change the visible timing.

[0050] In the present embodiment, if the height force S of the raised line drawing is in the range of 5 μΐη to 150 / im, the effects of FIGS. 4 to 6 are improved, and thus the line drawing is improved. Is preferably set in the range of 5 / im to 150 / im.

In summary, the present embodiment forms a predetermined image including a first area, a second area, and a third area on a base material, and forms at least a part of the first area. The second region is formed such that the first region, the second region, and the third region are formed such that at least a part of the second region is adjacent or close to the second region. Area 3 is composed of raised lines composed of glossy ink, and the arrangement direction of the lines is arranged in different directions for the first area, the second area and the third area. When observing the anti-counterfeit printed matter gradually from the vertical direction to the horizontal direction, the anti-counterfeit print is directed from the first area to the third area or from the third area to the first area. The color or lightness and darkness gradually changes according to the force, so that the specified image can be seen with a lively feeling . [0052] Further, the printed matter forms a line image having a different arrangement direction for each region with glossy ink. For this reason, the arrangement direction of the line pattern in a certain area differs from the scanning line of a copying machine or the like, and when a copy is made by a copying machine or the like, the printed matter is different from the printed matter according to the present embodiment. The prevention effect is obtained.

 Further, the printed matter according to the present embodiment forms a predetermined image including n (n is an integer of 3 or more) regions on the base material, and the n regions are the first region and the second region. Area, a third area, an n-th area and an n-th area, and a second area is formed such that at least a part of the first area is adjacent or close to the first area. A third region is formed such that at least a part of the second region is adjacent or adjacent, and an n-th region is formed such that at least a portion of the (n−1) -th region is adjacent or adjacent. The area is composed of raised line objects made of glossy ink, and the arrangement direction of the line objects is the first region, the second region, the third region, the n-th region and the n-th region. By arranging the printed matter in different directions for each area, when the printed matter is observed gradually from the vertical direction to the horizontal direction, Since the color or lightness and darkness change gradually and continuously as the area n or the nth area moves toward the first area, a predetermined image can be visually recognized with a sense of liveliness.

 [0054] Further, since the printed matter forms a line pattern having a different arrangement direction for each area with glossy ink, the difference between the arrangement direction of the line pattern in a certain area and the scanning line of a copying machine or the like is different. Therefore, when a copy is made by a copying machine or the like, the printed matter is different from the printed matter of the present invention.

 Further, a second region is formed so as to surround the periphery of the first region, and a third region is formed so as to surround the periphery of the second region. The effects of FIGS. 4 to 6 are improved by forming the n-th region so as to surround the periphery of. In this case, the positional relationship between the regions may be any state as long as they are adjacent or close to each other.

Further, the arrangement direction of the line drawing in the first area is α 1, the angle in the arrangement direction of the line drawing in the second area is _α 2, The angle in the array direction of the line drawing in the area is increased by 3. When η is satisfied, the condition of 1 <<2 <<3 <... <<η-1 <<η or 1> ひ 2> 3 3> 4 to 6 are improved.

 [0057] The predetermined image in the printed matter according to the present embodiment shown in Fig. 1 needs to be printed with glossy ink. The glossy ink mentioned here may be a transparent or translucent ink as long as the image itself has swelling as long as the surface has a specular gloss. In order to improve the effects shown in FIGS. 4 to 6, it is necessary to include an optically variable pigment in the glossy ink. Pearl ink, flaky pigment, metal powder pigment, glass flake or cholesteric liquid crystal pigment, etc., must be used. Need to be blended.

 [0058] In the present embodiment, an ink containing a pearl pigment can provide the most remarkable effect.

 [0059] Further, the above-mentioned optically variable pigment preferably has planar orientation. Fig. 8 shows an enlarged view of an ink film printed with an ink containing a pigment without planar orientation, and Fig. 9 shows an enlarged image of an ink film printed with an ink containing an optically variable pigment with planar orientation. The figure is shown. When printing with an ink containing a pigment that does not have planar orientation, the orientation of the pigment in the ink film of the image is randomly oriented throughout the ink film as shown in Fig. 8. You can see that. When printing with an ink containing an optically variable pigment with planar orientation, the orientation of the pigment in the ink film of the object is perfectly aligned with the surface of the ink film as shown in Fig. 9. You can see that. Here, the planar orientation (leafing effect) refers to a pigment that has been subjected to water- and oil-repellent treatment. Since it is difficult to settle down on the surface, it is well oriented on the surface of the ink film. Pigment that has not been treated for water or oil repellency, that is, that does not have planar orientation, while drying, causes the ink to dry before the pigment is oriented. Since the orientation is not well-defined, the visual recognition effect is inferior to that of a pigment having water and oil repellency.

Next, the effect of the ink containing the optically variable pigment will be described. Examples of the optically changing pigment include pearl pigment, flake pigment, metal powder pigment, glass flake pigment, cholesteric liquid crystal pigment and the like. However, the interference light varies depending on the refractive index, shape, thickness, size, distribution of particles in the ink film, and the like of the optically variable pigment. Fig. 10 shows an oblique view of a printed material printed with an ink containing an optically variable pigment. As shown in Fig. 10, light from incident light X is reflected on the ink film, and the reflected light Y is reflected by the optically variable pigment and is observed from the vertical direction of the optically variable pigment. And a different color of light is generated and becomes interference light, which is visually recognized.

 [0061] The pearl pigment used here may be an iris pearl pigment, a dichroic pearl pigment, or another flaky pigment. The pearl pigment has a particle size of 1 zm 150 μm, preferably 5 μm 50 μm, and an average particle size of about 10 μm to 25 μm.

 When the anti-counterfeit printed matter according to the present embodiment is observed from the vertical direction to the horizontal direction gradually, the color or the brightness changes continuously and gradually, so that the predetermined image has a sense of dynamism. it can.

 When the anti-counterfeit printed matter according to the present embodiment is gradually observed from the vertical direction to the horizontal direction, it is necessary to make the image with a swelling in order for the color or lightness and darkness to change continuously and gradually. Yes, the height force of the object is preferably in the range of 5 μΐη to 150 / im. If the height of the ink is less than 5 μΐη, the above visual effect is difficult to confirm, and if it exceeds 150 μm, it becomes difficult to produce.

 [0064] The shape of the line pattern in the present embodiment can be formed in a straight line pattern, a curved line pattern, or the like, and is not particularly limited.

 Further, it is preferable to use a solid line as each of the line objects 2a, 3a, and 4a shown in FIG.

 However, a dashed line may be used like the line objects 2b, 3b, and 4b shown in FIG.

 Further, it is acceptable that solid lines, broken lines, and the like are formed by minute characters. In addition, by gradually or continuously changing the image width of each object of the line object, the forgery-preventing print according to the present embodiment is observed from the vertical direction to the horizontal direction, and the color Alternatively, light and dark are gradually and clearly changed, and a predetermined image can be visually recognized with a gradation expression.

[0068] In the present embodiment, the outer shape P of each region is a star as shown in FIG. 12A, a triangle as shown in FIG. 12B, a square as shown in FIG. 12C, or a circle, polygon, logo mark, or the like. Any shape such as an arbitrary figure may be used. As shown in FIG. 13A to FIG. 13C, a plurality of regions in the present embodiment are obtained by dividing the outer periphery of a predetermined image and an arbitrary point in the predetermined image in a vertical direction into plural regions. Each of the divided points serves as a reference for each of the boundary areas of the plurality of areas, and the shape of each of the boundary areas forms a plurality of areas with the same or similar shape as the outer shape of the predetermined image. Is formed.

 FIG. 13A and FIG. 13C show a case where an arbitrary point is provided at the center 21a of the outer contour 20 in a predetermined image, which corresponds to a case where the area is divided into two in the vertical direction 22 and three areas are provided.

 Further, FIGS. 14A to 14C show a case where an arbitrary point is provided at a point 21b shifted from the center of the outer contour 20 in a predetermined image. Corresponds to the case of providing. In the images shown in FIG. 13A—FIG. 13C and FIG. 14A, a second region is formed so as to surround the first region, and the third region is formed so as to surround the second region. An area is formed.

 The present embodiment is not limited to this. As shown in FIG. 15A, the second region 3 is formed so that at least a part of the first region 2 is adjacent to the first region 2, and the second region The third region 4 may be formed so that at least a part of the third region 3 is adjacent, and the fourth region 5 may be formed so that at least a part of the third region 4 is adjacent. Alternatively, as shown in FIG. 15B, the second region 3 is formed so that at least a part of the first region 2 is close, and the third region 4 is so formed that at least a part of the second region 3 is close. May be formed, and the fourth region 5 may be formed so that at least a part of the third region 4 approaches.

 [0073] As used herein, the term "adjacent" means that at least a part of a region is in contact, or at least a part of a region is overlapped and is in contact. Say that there is.

 [0074] In the present embodiment, the close distance, that is, the distance Q between the regions is preferably 5 mm or less.

 The printed material according to the present embodiment is not limited to the shapes shown in FIGS. 12 to 14, and may have a shape as shown in FIGS. 16A and 16D as another example.

FIG. 16A is formed by characters, and the arrangement angle of the line pattern in each character region is different. The outer shape gradually changes from the first area to the n-th area As an example, FIG. 16B shows a state where the shape gradually changes from a square to a triangle. In addition, the arrangement angles of the lines in the graphic regions are different.

[0077] Fig. 16C shows a pattern formed by petals, in which the arrangement angle of the line pattern in each petal region is different.

 FIG. 16D is formed by the logo mark, and the arrangement angle of the line pattern in a partial area of the logo mark is different.

 [0079] The angle in the arrangement direction of the objects in the printed matter according to the present embodiment may be an angular force S1 degrees or more and 179 degrees or less formed by the images in adjacent areas, and is preferably 5 degrees or more and 45 degrees or less. Desirable to be in the range.

 [0080] The predetermined image in the printed matter according to the present embodiment is an oxidation polymerization type ink, a UV curing type ink, an electron beam curing type ink, an ink having both ultraviolet curing and oxidation polymerization functions (see Patent No. 2113880), or a two-component ink. Mixed inks are preferred. The printing method is not particularly limited, but an intaglio printing method or a screen printing method is preferable.

 [0081] The pearl pigment used here may be an iris pearl pigment, a dichroic pearl pigment, or another flaky pigment. However, a material that has been subjected to a surface treatment of the pigment (for example, a water-repellent or oil-repellent treatment as disclosed in JP-A-2001-106937) so that the pigment is oriented on the surface of the object on which the swelling is present. By using the pigment, the orientation (leafing effect) of the flaky pigment can be improved, and as shown in FIG. 9, the pigment is oriented on the surface of the printed material, and the above-described visual recognition effect can be improved.

 [0082] In this case, since an image having a swelling needs to have quick curability, a UV curable ink, an electron beam curable ink, an ink having both UV curable and oxidative polymerization functions (see Patent No. 2113880), Alternatively, it is necessary to print with an ink containing a pigment that has been subjected to the surface treatment (water-repellent and oil-repellent treatment) described above to the two-component mixed ink, and after printing, irradiate with active energy rays such as an ultraviolet irradiation device. There is.

 [0083] Therefore, the pigment does not settle even when a raised image is used, and the pigment is oriented on the surface of the printed material as shown in Fig. 9, so that the above-mentioned visual recognition effect can be improved.

[0084] In the case where the water- and oil-repellent treatment has not been performed, the ink hardens before the flake pigment is oriented. The effect is inferior to that of a pigment which has been treated with water and oil repellency.

 [0085] Further, in the printed matter according to the present embodiment, the predetermined image is printed over the region where the light absorbing layer is provided, so that the visual recognition effect described with reference to FIGS. 4 to 6 is improved. The light absorbing layer mentioned here is formed by the color of printing or the color of the substrate having low light reflectance, that is, high density, and the black color is most effective. In addition, the effect of preventing forgery is improved by printing the region provided with the light absorbing layer with an ink containing an infrared absorbing material or a magnetic material. The printing method for undercoating a predetermined image is not particularly limited, but an offset printing technique is preferable. The printing method of the predetermined image is not particularly limited, but it is preferable to use an intaglio printing technique or a screen printing technique. The viscosity of the ink used for printing a predetermined image is about 5 poise to about 200 boil, and between printing and drying, the optically variable pigment having a planar orientation on the surface and the optically oriented pigment on the surface Variation A viscosity that can be separated into a pigment having no planar orientation below the pigment is preferable. In addition, no special adjustment is required for adjusting the printing press, and printing can be performed with general settings.

 [0086] As the base material in the printed matter according to the present embodiment, paper sheets, plastic films, metals, cloths, and the like can be used.
