Description

Technical Field

[0001] The present invention relates to a three-dimensional pattern printed matter for preventing forgery and alteration in the field of precious printed matters that require individual identification, such as banknotes, passports, securities, identity certificates, cards, tickets, etc., which are security printed matters that require anti-forgery effects.

Background Art

[0002] Conventionally, in precious printed matters such as banknotes, stock certificates, securities, tickets, cards, etc., where it is necessary to prevent forgery and alteration, in order to give a visual anti-forgery effect, an anti-forgery relief pattern is often applied to some or a plurality of locations such as the background image on the face of the note. This relief pattern is a pattern that three-dimensionally represents some motif on a two-dimensional plane. The relief pattern is generally formed from a plurality of ten thousand lines created to form ground patterns, colored patterns, patterns, etc. that are widely used in the design of security printed matters.

[0003] FIG. 10 is a diagram showing an example of a relief pattern of a conventional three-dimensional pattern printed matter. The conventional relief pattern 100 shown in FIG. 10 has a pattern portion 102 and a background portion 103. The pattern portion 102 is composed of a binary image (cherry blossom pattern) serving as a motif. The pattern portion 102 is formed by a plurality of pattern lines 105, and the background portion 103 is formed by a plurality of background lines 104. The boundary between the pattern line 105 and the background line 104 is zigzag. Thereby, a shadow (darkness) is expressed at a portion where the line pitch becomes narrow at the boundary between the pattern line 105 and the background line 104, and light (brightness) is expressed at a portion where the line pitch becomes wide. In this way, in the conventional three-dimensional pattern printed matter, by giving light and darkness to the boundary between the pattern portion 102 and the background portion 103, the binary image of the motif is visually recognized three-dimensionally.

[0004] In recent years, further improvement in design has been required to make the motif visually recognized more three-dimensionally. As a technique for visually recognizing the motif three-dimensionally, for example, there is one as described in Patent Document 1. FIG. 11 is a diagram showing an example of a relief pattern according to the technique disclosed in Patent Document 1. The relief pattern 200 shown in FIG. 11 has a pattern portion 202 formed by a binary image (cherry blossom pattern) serving as a motif and a background portion 203. The pattern portion 202 is formed by a plurality of pattern lines 205, and the background portion 203 is formed by a plurality of background lines 204.

[0005] In the region A that forms "bright" in the relief pattern 200 shown in Patent Document 1, the background lines 204 and the pattern lines 205 are eliminated. And in the region B that forms "dark", the ends of the background lines 204 and the ends of the pattern lines 205 are arranged so as to sandwich each other.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, in the technique described in Patent Document 1, in order to form "dark" in the relief pattern, the background lines and the pattern lines are arranged so as to sandwich each other. As a result, in the technique described in Patent Document 1, a region where the interval between the lines becomes dense is generated, and it has been difficult to express a complex pattern.

[0008] An object of the present invention is to provide a three-dimensional pattern printed matter having a relief pattern that can cope with complex patterns and has an increased three-dimensional effect in consideration of the above problems.

Means for Solving the Problems

[0009] In order to solve the above problems and achieve the object of the present invention, a three-dimensional pattern printed matter includes a base material and a relief pattern formed on the base material and constituted by a ten thousand-line pattern formed by a plurality of ruled lines. The relief pattern has a pattern portion formed by a plurality of pattern ruled lines, a background portion formed by a plurality of background ruled lines, and a boundary portion formed by a boundary ruled line surrounding at least a part of the periphery of the pattern portion. The first ruled line width of the pattern ruled line, the second ruled line width of the background ruled line, and the third ruled line width of the boundary ruled line are formed with different thicknesses respectively.

[0010] Further, in the three-dimensional pattern printed matter, the first ruled line width is formed thicker than the second ruled line width and the third ruled line width, and the third ruled line width is formed thinner than the second ruled line width.

[0011] Furthermore, in the three-dimensional pattern printed matter, the first ruled line width is formed thinner than the second ruled line width and the third ruled line width, and the third ruled line width is formed thicker than the second ruled line width.

Advantages of the Invention

[0012] In the three-dimensional pattern printed matter having the above configuration, it is possible to cope with complex patterns and provide a relief pattern with enhanced three-dimensional effect. Also, when the pattern portion and the boundary portion are formed with the thickest ruled lines and the thinnest ruled lines respectively within the relief pattern, the largest contrast in shading occurs between the pattern portion and the boundary portion, so that the pattern portion has a more three-dimensional effect and is more visible.

MODE FOR CARRYING OUT THE INVENTION

[0014] Hereinafter, the three-dimensional pattern printed matter according to the embodiment example will be described with reference to FIGS. 1 to. In addition, the same code | symbol is attached | subjected to the common member in each figure.

[0015] 1. First Embodiment Example First, the structure of the three-dimensional pattern printed matter according to the first embodiment example (hereinafter referred to as "this example") will be described with reference to FIGS. 1, 2, and 3. FIG. 1 is a plan view showing the three-dimensional pattern printed matter of this example.

[0016] The three-dimensional pattern printed matter S of this example shown in FIG. 1 is a printed matter used for, for example, banknotes, passports, securities, identity certificates, cards, tickets, etc. As shown in FIG. 1, the three-dimensional pattern printed matter S includes a base material P and a relief pattern 1 formed on at least a part of the base material P. In this example, a cherry blossom is applied as a motif. Note that the motif is not limited to a cherry blossom, and various other motifs such as a circle and a star can be applied.

[0017] Figure 2 is a view showing the relief pattern of the three-dimensional pattern print of the present example shown in Figure 1. The relief pattern 1 is composed of a myriad line pattern formed by a plurality of wavy ruled lines. In this example, the pitch interval of the ruled lines is formed to be constant. The relief pattern 1 has a pattern part 2 that forms the motif of a cherry blossom flower, a background part 3 that forms the background of the relief pattern 1, and a boundary part 6 that forms the contour of the motif. The boundary part 6 is arranged so as to surround at least a part of the periphery of the pattern part 2.

[0018] The pattern part 2 is formed by a plurality of pattern ruled lines 5, the background part 3 is formed by a plurality of background ruled lines 4, and the boundary part 6 is formed by a plurality of boundary ruled lines 7. The pattern ruled lines 5 and the background ruled lines 4 are connected via the boundary ruled lines 7 in the region where the boundary part 6 is formed. And the region where the boundary part 6 formed by the plurality of boundary ruled lines 7 is arranged, the region A shown in Figure 2 represents the "light" of the motif.

[0019] Also, in the region B which becomes the "dark" of the motif, there is no boundary ruled line 7 between the background ruled line 4 and the pattern ruled line 5, and the background ruled line 4 and the pattern ruled line 5 are directly connected. The region B is arranged at a position on the opposite side of the region A with the pattern part 2 in between. That is, the boundary part 6 is formed only on one side of the pattern part 2. Thereby, it can be expressed so that the pattern part 2 appears to protrude in one direction (in the example shown in Figure 2, diagonally downward to the right), and the three-dimensional effect of the pattern part 2 can be enhanced.

[0020] In this example, an example in which the boundary part 6 is formed only on one side of the pattern part 2 has been described, but it is not limited to this, and the boundary part 6 may be formed on both sides of the pattern part 2, that is, so as to surround the entire pattern part 2. When the boundary part 6 is formed so as to surround the entire pattern part 2, it can be expressed so that the pattern part 2 appears to protrude to the center, and similarly the three-dimensional effect of the pattern part 2 can be enhanced. Also, the boundary part 6 may be formed on at least a part of the periphery of the pattern part 2.

[0021] Figure 3 is a view showing an enlargement of the region A shown in Figure 2, that is, the boundary part 6. As shown in FIG. 3, the pattern line 5 is formed with a first line width W1, the background line 4 is formed with a second line width W2, and the boundary line 7 is formed with a third line width W3. The lengths of the first line width W1, the second line width W2, and the third line width W3 are formed to have different lengths respectively.

[0022] Also, in this example, the first line width W1 is formed thicker than the second line width W2 and the third line width W3. And the third line width W3 is thinner than the second line width W2, that is, it is formed to be the thinnest. Therefore, the first line width W1 of the pattern line 5, the second line width W2 of the background line 4, and the third line width W3 of the boundary line 7 have a relationship of W1>W2>W3. Also, in this example, the difference in length between the first line width W1 and the third line width W3 is formed larger than the difference in length between the second line width W2 and the third line width W3.

[0023] Note that the relationship of the lengths of the first line width W1, the second line width W2, and the third line width W3 is not limited to the example described above. For example, the thicknesses of the first line width W1 and the second line width W2 may be the same. Also, the thickness of the lines constituting each part is not limited to be the same, but even in that case, the first line width W1 of the pattern line 5, the second line width W2 of the background line 4, and the third line width W3 of the boundary line 7 have a relationship of W1>W2>W3. For example, in a plurality of pattern lines 5, when the line width W1 is 50 μm and 60 μm, the second line width W2 of the background line 4 is formed thinner than 50 μm.

[0024] Thus, according to the three-dimensional pattern printed matter of this example, by providing a boundary portion 6 with different line thicknesses between the pattern portion 2 and the background portion 3 in the relief pattern 1, the contour of the pattern portion 2 can be made clear by the boundary portion 6. Thereby, the three-dimensional feeling of the pattern portion 2 can be increased. Also, as described above, by forming the third line width W3 of the boundary portion 6 thinner than the other lines, the contour of the pattern portion 2 can be emphasized.

[0025] Furthermore, the pattern lines 5 forming the pattern portion 2, the background lines 4 forming the background portion 3, and the boundary portion 6 are represented by changing the thickness of a single line. Thereby, it is possible to provide a three-dimensional pattern printed matter that can also handle complex patterns.

[0026] 2. Second Embodiment Example Next, the configuration of the three-dimensional pattern printed matter according to the second embodiment example will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing the relief pattern of the three-dimensional pattern printed matter according to the second embodiment example. FIG. 5 is an enlarged view showing the boundary portion according to the second embodiment example.

[0027] As shown in FIG. 4, the relief pattern 1B of the three-dimensional pattern printed matter according to the second embodiment example is an inverted image, that is, a negative image, with respect to the relief pattern 1 of the three-dimensional pattern printed matter according to the first embodiment example. Therefore, here, the same reference numerals are given to the portions common to the relief pattern 1 of the three-dimensional pattern printed matter according to the first embodiment example, and the overlapping description is omitted.

[0028] As shown in FIG. 4, the relief pattern 1B has a pattern portion 2B, a background portion 3B, and a boundary portion 6B. The pattern portion 2B is formed by a plurality of pattern lines 5B, the background portion 3B is formed by a plurality of background lines 4B, and the boundary portion 6B is formed by a plurality of boundary lines 7B. In the region where the boundary portion 6B is arranged, the pattern lines 5B and the background lines 4B are connected via the boundary lines 7B, and in the region where the boundary portion 6B is not arranged, the pattern lines 5B and the background lines 4B are directly connected.

[0029] As shown in FIG. 5, the pattern line 5B is formed with a first line width W1, the background line 4B is formed with a second line width W2, and the boundary line 7B is formed with a third line width W3. In the second embodiment, the first line width W1 is formed thinner than the second line width W2 and the third line width W3. And the third line width W3 is thicker than the second line width W2, that is, it is formed thickest. Therefore, the first line width W1 of the pattern portion 2B, the second line width W2 of the background portion 3B, and the third line width W3 of the boundary portion 6B have a relationship of W1 < W2 < W3.

[0030] Even in the relationship of the line widths described above, the boundary portion 6B can emphasize the contour of the pattern portion 2B and increase the three-dimensional effect of the pattern portion 2B. In the first embodiment, the third line width W3 of the boundary portion 6 was formed thinnest compared to other lines to emphasize the contour of the pattern portion 2, but in the second embodiment, the contour of the pattern portion 2 can be emphasized by forming it thickest.

[0031] Other configurations are the same as those of the relief pattern 1 of the three-dimensional pattern printed matter according to the first embodiment, so their descriptions are omitted. Also by the relief pattern 1B of the three-dimensional pattern printed matter having such a configuration, the same operational effects as those of the three-dimensional pattern printed matter according to the first embodiment described above can be obtained.

[0032] 3. Third Embodiment Next, the configuration of the three-dimensional pattern printed matter according to the third embodiment will be described with reference to FIG. 6. FIG. 6 is a diagram showing the relief pattern of the three-dimensional pattern printed matter according to the third embodiment.

[0033] The difference between the relief pattern 1C of the three-dimensional pattern printed matter according to this third embodiment and the relief pattern 1 of the three-dimensional pattern printed matter according to the first embodiment is the configuration of the lines forming the myriad line pattern. Therefore, here, the same reference numerals are given to the parts common to the relief pattern 1 of the three-dimensional pattern printed matter according to the first embodiment, and the overlapping descriptions are omitted.

[0034] As shown in FIG. 6, the relief pattern 1C has a pattern portion 2C, a background portion 3C, and a boundary portion 6C. The pattern portion 2C is formed by a plurality of pattern lines 5C, the background portion 3C is formed by a plurality of background lines 4C, and the boundary portion 6C is formed by a plurality of boundary lines 7C. In the region where the boundary portion 6C is arranged, the pattern line 5C and the background line 4C are connected via the boundary line 7C, and in the region where the boundary line 7C is not arranged, the pattern line 5C and the background line 4C are directly connected.

[0035] In addition, the pitch intervals of the plurality of lines constituting the relief pattern 1C are not all constant, and there are regions where some pitch intervals are different. That is, there are regions where the pitch interval is narrowed and regions where the pitch interval is widened. In the first embodiment example and the second embodiment example, the three-dimensional effect of the pattern portion 2 is enhanced by the difference in the length of the line widths constituting each part, but in the third embodiment example, the three-dimensional effect can be further enhanced by the difference in the pitch intervals of the lines. Specifically, in FIG. 6, in the region where the pitch interval is narrowed and the region where the pitch interval is widened, the widened region appears in the foreground, and the entire relief pattern 1C is visually recognized as a three-dimensional sphere.

[0036] Other configurations are the same as those of the relief pattern 1 of the three-dimensional pattern printed matter according to the first embodiment example, and thus their descriptions are omitted. Also by the relief pattern 1C of the three-dimensional pattern printed matter having such a configuration, the same operational effects as those of the three-dimensional pattern printed matter according to the above-described first embodiment example can be obtained.

[0037] 4. Fourth Embodiment Example Next, the configuration of the three-dimensional pattern printed matter according to the fourth embodiment example will be described with reference to FIG. 7. FIG. 7 is a diagram showing the relief pattern of the three-dimensional pattern printed matter according to the fourth embodiment example.

[0038] The difference between the relief pattern 1D of the three-dimensional pattern printed matter according to this fourth exemplary embodiment and the relief pattern 1 of the three-dimensional pattern printed matter according to the first exemplary embodiment lies in the configuration of the ruled lines forming the myriad-line pattern. Therefore, here, the parts common to the relief pattern 1 of the three-dimensional pattern printed matter according to the first exemplary embodiment are denoted by the same reference numerals, and the overlapping descriptions are omitted.

[0039] As shown in FIG. 7, the relief pattern 1D has a pattern portion 2D, a background portion 3D, and a boundary portion 6D. The pattern portion 2D is formed by a plurality of pattern ruled lines 5D, the background portion 3D is formed by a plurality of background ruled lines 4D, and the boundary portion 6D is formed by a plurality of boundary ruled lines 7D. In the region where the boundary portion 6D is arranged, the pattern ruled lines 5D and the background ruled lines 4D are connected via the boundary ruled lines 7D, and in the region where the boundary portion 6D is not arranged, the pattern ruled lines 5D and the background ruled lines 4D are directly connected.

[0040] Also, the plurality of ruled lines constituting the relief pattern 1D are not formed in a wavy line shape but in a straight line shape. Note that the pitch intervals of the ruled lines are not limited to a constant interval, and some pitch intervals may be made different intervals as in the third exemplary embodiment.

[0041] Other configurations are the same as those of the relief pattern 1 of the three-dimensional pattern printed matter according to the first exemplary embodiment, and thus the descriptions thereof are omitted. Also, with the relief pattern 1D of the three-dimensional pattern printed matter having such a configuration, the same operational effects as those of the three-dimensional pattern printed matter according to the above-described first exemplary embodiment can be obtained.

[0042] 5. Fifth Exemplary Embodiment Next, the configuration of the three-dimensional pattern printed matter according to the fifth exemplary embodiment will be described with reference to FIG. 8. FIG. 8 is a diagram showing the relief pattern of the three-dimensional pattern printed matter according to the fifth exemplary embodiment.

[0043] The difference between the relief pattern 1E of the three-dimensional pattern print according to this fifth embodiment and the relief pattern 1 of the three-dimensional pattern print according to the first embodiment lies in the configuration of the ruled lines forming the ten-thousand-line pattern. Therefore, here, the same reference numerals are given to the parts common to the relief pattern 1 of the three-dimensional pattern print according to the first embodiment, and the overlapping descriptions are omitted.

[0044] As shown in FIG. 8, the relief pattern 1E has a pattern part 2E, a background part 3E, and a boundary part 6E. The pattern part 2E is formed by a plurality of pattern ruled lines 5E, the background part 3E is formed by a plurality of background ruled lines 4E, and the boundary part 6E is formed by a plurality of boundary ruled lines 7E. In the region where the boundary part 6E is arranged, the pattern ruled lines 5E and the background ruled lines 4E are connected via the boundary ruled lines 7E, and in the region where the boundary part 6E is not arranged, the pattern ruled lines 5E and the background ruled lines 4E are directly connected.

[0045] Also, the plurality of ruled lines constituting the relief pattern 1E are not wavy but are formed in a circular shape. And the plurality of ruled lines are arranged concentrically from the center of the relief pattern 1E. Note that the pitch intervals of the ruled lines are not limited to a constant interval, and some of the pitch intervals may be different. Also, in the example shown in FIG. 8, an example of arranging the ruled lines concentrically from the center of the relief pattern 1E has been described, but it is not limited to this, and the center of the concentric circles of the ruled lines may be arranged at a position different from the center of the relief pattern 1E.

[0046] The other configurations are the same as those of the relief pattern 1 of the three-dimensional pattern print according to the first embodiment, so their descriptions are omitted. Also, with the relief pattern 1E of the three-dimensional pattern print having such a configuration, the same operational effects as those of the three-dimensional pattern print according to the above-described first embodiment can be obtained.

[0047] 6. Sixth Embodiment Next, the configuration of the three-dimensional pattern print according to the sixth embodiment will be described with reference to FIG. 9. FIG. 9 is a diagram showing the relief pattern of the three-dimensional pattern print according to the sixth embodiment.

[0048] The difference between the relief pattern 1F of the three-dimensional pattern print according to this sixth embodiment and the relief pattern 1 of the three-dimensional pattern print according to the first embodiment lies in the configuration of the ruled lines forming the myriad-line pattern. Therefore, here, the parts common to the relief pattern 1 of the three-dimensional pattern print according to the first embodiment are denoted by the same reference numerals, and duplicate descriptions are omitted.

[0049] As shown in FIG. 9, the relief pattern 1F has a pattern portion 2F, a background portion 3F, and a boundary portion 6F. The pattern portion 2F is formed by a plurality of pattern ruled lines 5F, the background portion 3F is formed by a plurality of background ruled lines 4F, and the boundary portion 6F is formed by a plurality of boundary ruled lines 7F. In the region where the boundary portion 6F is arranged, the pattern ruled lines 5F and the background ruled lines 4F are connected via the boundary ruled lines 7F, and in the region where the boundary portion 6F is not arranged, the pattern ruled lines 5F and the background ruled lines 4F are directly connected.

[0050] Also, the plurality of ruled lines constituting the relief pattern 1F are formed in a straight line. Also, the ruled lines are bent in the middle. And the arrangement directions of the plurality of ruled lines are directed in different directions in the middle. Therefore, the plurality of ruled lines of the relief pattern 1F shown in FIG. 9 form a hexagon. Note that the shape formed by the ruled lines is not limited to a hexagon, and may be other various shapes such as a pentagon or an octagon. Also, the shape of the ruled lines is not limited to a straight line, and may be a curved line. Furthermore, the pitch intervals of the ruled lines are not all limited to a constant interval, and some of the pitch intervals may be different intervals.

[0051] Other configurations are the same as those of the relief pattern 1 of the three-dimensional pattern print according to the first embodiment, and thus their descriptions are omitted. Also by the relief pattern 1F of the three-dimensional pattern print having such a configuration, the same operational effects as those of the three-dimensional pattern print according to the above-described first embodiment can be obtained.

[0052] Note that the present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention described in the claims.

[0053] The base material of the three-dimensional pattern printed matter of the present invention is not particularly limited, and paper materials such as high-quality paper, coated paper, and art paper can be used. Further, films, plastics, and composite materials thereof can also be used.

[0054] Furthermore, since it is essential that the relief pattern 1 is formed by the difference in the line widths of the pattern line 5, the background line 4, and the boundary line 6, the same operational effects as those of the three-dimensional pattern printed matter can be obtained even with the digital data before outputting to the base material P.

[0055] As the printing method of the three-dimensional pattern printed matter of the present invention, there is no particular limitation, such as offset printing, gravure printing, intaglio printing, screen printing, flexographic printing, digital printing, inkjet printer, laser printer, etc.
