Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for preventing forgery of valuable printed matter such as certificates and securities by a copying machine.

[0002]

2. Description of the Related Art Conventionally, latent image patterns used in this type of copy-proof printed matter are large or small in halftone dots, or
A latent image is formed due to the difference in the thickness of the lines such as lines, and these are recognized as printed matter having a uniform density when forming a pattern on the entire printing surface. When a printed matter having such a latent image is copied by a copying machine, a latent image appears by causing a density difference between the minute dots which are not reproduced and the minute dots which are reproduced. However, the printed matter produced by such a principle has a drawback that the boundary between the latent image portion and the background portion other than the latent image is easily recognizable when visually observed, and the latent image is visible even in the initial printed matter state. It was

[0003]

Generally, as a principle of a copying machine, an image is formed by projecting light on an object to be copied and detecting the reflected light. However, it is difficult to adjust the light projection of the copying machine to the intersections of the image lines, although the light projection amount of the copying machine becomes too large for the intersections where the image lines of the object to be copied are dense. As a result, light is fogged at the image line intersections of the printed matter, and the image lines tend to be thick or the intersections are likely to be deformed.

According to the present invention, when a latent image pattern (hidden image) for copy protection is formed on a printed matter, the size of halftone dots is not utilized, but the intersection of straight lines is easily enlarged by copying.
The printed matter produced by the method of the present invention is completely invisible because the boundary between the latent image portion and the background portion other than the latent image cannot be visually recognized. The object of the present invention is to produce a printed matter having an anti-counterfeiting effect in which a latent image appears clearly in a copy although it is imaged, and a warning character or the like appears in the copy.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a printed matter having a copy preventing effect and a method for producing the same according to the present invention will be described below.
Example 1 In the first pattern of FIG. 1, I is a unit rectangular drawing line, and 1, 2, 3, 3 ′ are straight line groups within the unit rectangular drawing line I. At this time, 1, 2, 3, and 3'are diagonal lines, of which the diagonal lines 3 and 3'change in angle at a certain point and exist on the extension of the straight line of the diagonal line 1 or the diagonal line 2.
In addition, a is the drawing area of diagonal line 1, d is the drawing area of diagonal line 2,
b and c are the drawing area of the diagonal line 3 and the diagonal line 3 '. Further, the slanted lines 1 and 2 are straight lines that have directionality and are in contact with one side or one corner of the unit rectangular drawing line I. The slanted lines 3 and 3 '
Has two directions, and the diagonal line 3 is 1 of the unit rectangular drawing line I.
The diagonal line 3 ′ is a straight line which is in contact with the side, and the diagonal line 3 ′ is a straight line which is not in contact with the unit rectangular drawing line I.

In the second pattern of FIG. 2, I'is a unit rectangular drawing line, 4 is a diagonal line having the same angle as the diagonal line 1 in FIG. 1, and 5 is a diagonal line having the same angle as the diagonal line 2 in FIG. It is a straight line that is not in contact with the image line I ′. Further, e is the drawing area of the diagonal line 4, and f is the drawing area of the diagonal line 5. At this time, if the total drawing area in the straight line group in FIG. 1 is A, A = 2a +
It becomes 2b + 2c + 2d. Further, when the total of the drawing area in the straight line group of FIG. 2 is A ′, A ′ = 2e + 2f, and the total of the drawing area in the straight line group is A = A ′, the unit rectangular drawing line I and the unit rectangle. The total area of the drawing lines in the straight line group within the drawing line I ′ is equal.

With such an image line configuration of the first and second patterns, a minute size which is usually difficult to visually recognize,
Further, by arranging the drawing structures in the unit rectangular drawing lines (I, I ′) of the first pattern and the second pattern at the same angle and the same direction as shown in FIG. Even if they are different, they are likely to look the same in appearance (portion W in FIG. 4). When the drawing line configurations of these two types of patterns are arranged and printed in, for example, a character shape L (portion shown by a phantom line in FIG. 4), that is, the shape of the English character “C”, as shown in FIG. The printed pattern D can be printed on the surface of the sheet, and the latent image cannot be confirmed because the print density is apparently the same.

As shown in FIG. 5, a copy of the printed matter on the paper P is C, T is the area printed and copied with the second pattern, and S is the first area. This is an area printed and copied with a pattern. At this time, the intersections of the slanted lines 1, 2, and 3 which are in contact with one side or one corner of the unit rectangular drawing line I having the first pattern of the drawing line configuration shown in FIG. The amount of light is too large, and the fogging of light causes thickening of the image lines and deformation of the image lines.

As a result, with respect to the printed pattern D shown in FIG. 4, the area S printed and copied in the drawing structure of the first pattern of the copy C shown in FIG. 5 is expressed with high density. On the other hand, the hatched lines 4 and 5 in FIG. 2 are reproduced as they are in the region T printed and copied in the second pattern of the copy C. Therefore, a density difference occurs between the first and second patterns as shown in FIG. 5, and the meaningful image of the English letter “C” can be easily recognized as a latent image.

[Embodiment 2] The first pattern of Embodiment 2 is
This is similar to FIG. 1 described above. In FIG. 6 which is the second putter, I ″ is a unit rectangular drawing line, slant lines 6 and slant lines 7 are slant lines at the same angle as slant line 1 in FIG. It is a slanted line and is a straight line that does not contact the unit rectangular drawing line I ″. The line widths of the slant lines 6 and 7 are half of the line width of the slant line 4 of FIG. 2, and the line widths of the slant lines 8 and 9 are 1 of the slant line 5 of FIG. It is configured with a line width of / 2. At this time, g is the area of the diagonal line 6, h is the area of the diagonal line 7, i is the area of the diagonal line 9, and j is the diagonal line 8.
And the distance between diagonal lines 6 and 7 and between diagonal lines 8 and 9 is k.

When the total drawing area of the straight line group in the first pattern is A, A = 2a + 2b + 2c + 2d (see FIG. 1 and the description above). Further, if the total of the drawing area in the straight line group in FIG. 6 is B, B = 2g + 2h + 2
i + 2j, and the total drawing area in the straight line group at this time is A = B, and the total drawing area in the unit rectangular drawing line I and the straight line group in the unit rectangular drawing line I ″ is equal.

With such an image line structure of the first and second patterns, the image size within the unit rectangular image line of the first and second patterns is further small, which is usually difficult to visually recognize. By arranging the line configurations at the same angle and the same direction as in FIG. 3, it is easy to look like the same shape even if the drawing line shapes are different. When these two types of image line configurations are arranged and printed in, for example, a character shape L ′ (portion shown by a phantom line in FIG. 7), that is, a shape of the English character “C”, as shown in FIG. Since the print pattern D ′ can be printed on the surface and the print densities are apparently the same, the latent image cannot be confirmed.

As shown in FIG. 8, a copy obtained by copying the printed matter of the paper P'is C ', X is an area printed by the second pattern, and S'is shown in FIG. This is an area printed and copied with the first pattern image line configuration. At this time, the intersections of the slanted lines 1, 2 and 3 contacting one side or one corner of the unit rectangular streak line I, which is the streak pattern of the first pattern of FIG. Too much, resulting in thickening of the lines and deformation of the lines due to fogging of light.

On the other hand, printing with the second pattern image line configuration,
In the copied area X, when the line widths of the slant lines 6, slant lines 7, slant lines 8 and slant lines 9 in FIG. 6 and the spacing k between the slant lines 6 and slant lines and between the slant lines 8 and the slant line 9 in FIG. Since it has a large size, it is difficult for a general copying machine to reproduce a fine image line due to the relation of resolution, and as a result, it is expressed in a light density. Therefore, a large density difference occurs between the first and second patterns, and the meaningful image of the English letter "C" can be more effectively and easily recognized as a latent image. (The density difference between the copies of FIGS. 5 and 8 is obvious.)

[Embodiment 3] FIG. 9 is a drawing pattern construction of a first pattern according to an embodiment of the present invention, which is constructed by a straight line where a straight line 10 and a straight line 11 intersect within a range II within a unit rectangle. Is the drawing area of the straight line 11, and m is the drawing area of the straight line 10. In the second pattern of FIG. 10, the intermittent straight lines 12, 12 ′, 13, 13 ′ within the unit rectangle II ′ are straight lines having the same angle as the straight line 10, and the intermittent straight lines 14, 1
4 ', 15, and 15' are straight lines having the same angle as the straight line 11. Further, p and n are configured with half the drawing line width of the straight line 11 in FIG. 9, o and q are configured with half the drawing line width of the straight line 10 in FIG. 9, and r is each intermittent. Straight line 12,12 ', 1
The intervals are 3, 13 ', 14, 14', 15, 15 '.

If the total drawing area of the straight line group in the first pattern of FIG. 9 is E, then E = u + m, and E ′ is the total drawing area of the straight line group in the second pattern of FIG. '= N + o + p + q. Further, the total drawing area of the straight line group is E = E ′, and the total drawing area of the straight line group in the unit rectangle II and the unit rectangle II ′ is the same. At this time, the straight line 10, the straight line 11 in the unit rectangle II and the intermittent straight lines 12, 12 ', 13, in the unit rectangle II',
13 ', 14, 14', 15 and 15 'have arbitrary positions and arbitrary lengths, and are arranged so as not to contact the boundary of the unit rectangle. That is, the straight line groups in each pattern are in a discontinuous state. Further, as a matter of course, no straight line exists at the boundary between the adjacent unit rectangles II and the adjacent unit rectangles II ′.

With the first and second pattern image structures as described above, the image pattern structure of the first pattern and the unit of the second pattern are so small that they are usually difficult to visually recognize. By forming the drawing line configurations within the rectangular drawing lines at the same angle, it is easy to look like the same shape even if the drawing line shapes are different. When these two types of image line configurations are arranged and printed in, for example, a character shape L "(portion shown by a phantom line in FIG. 11), that is, an English character" C ", as shown in FIG.
Since the print pattern D "can be printed on the surface of the paper P" and the print densities are apparently the same, the latent image cannot be confirmed. 12
As shown in, the copy of the printed matter on the paper P "is C"
Where Y is the area printed and copied with the second pattern image line configuration, and Z is the area printed and copied with the first pattern image line configuration. At this time, at the intersection of the straight line 10 and the straight line 11 which is the first pattern image line configuration shown in FIG. 9, the amount of light projected when copying is performed by a copying machine is too large, and light is easily fogged, resulting in thick line images and image lines. Causes line deformation.

On the other hand, the region Y printed and copied with the second pattern image line configuration of FIG. 10 is defined by the intermittent straight lines 1 of FIG.
When the drawing line widths and the drawing line intervals r of 2, 12 ', 13, 13', 14, 14 ', 15, and 15' are set, each straight line is formed to have a small size, so that a general copying machine is used. However, it is difficult to reproduce a minute image line due to the relation of resolution, and the image is expressed with a relatively low density. For this reason, the image density of the first pattern is high, and the image density of the second pattern is low, resulting in a large density difference. That is, after copying, a meaningful image of the English letter "C" can be easily recognized as a latent image. Further, in the printing of the first and second patterns of the image line configuration, since it is possible to print a tint block or the like with a light print density, even if a character or a pattern is printed on this, the contrast is large and the character etc. Since it can be easily read visually, it is particularly effective for use as a copy protection method for valuable printed matter such as certificates and securities.

[0025]

According to the first embodiment using the unit rectangular drawing line,
When the first line image structure is configured as a meaningful image and the second pattern image structure is used as a background, the two image structures have the same density, so that the printed material can be recognized only as a uniform background. However, when the image is reproduced by a copying machine, a density difference occurs due to an image line thickening at an intersection portion of the image line configurations of the first pattern. As a result, a meaningful image appears on the background, and it becomes visually clear that it is a duplicate.

In the second embodiment using the unit rectangular drawing lines, when the drawing pattern structure of the first pattern is set as a meaningful image and the drawing line structure of the second pattern is set as the background, the two pattern drawing line structures are equal. Since it is a density, it can be recognized only as a uniform background for printed matter. However, when the image is copied by a copying machine, the image line thickening occurs at the intersecting portion of the first pattern image line configuration, and the image line configuration becomes thin in the second pattern image line configuration, resulting in a remarkable density difference. As a result, a meaningful image appears against the background and becomes more clearly visible visually.

In the third embodiment which does not use the unit rectangular drawing line,
When the drawing line configuration of the first pattern is set as a meaningful image and the drawing line configuration of the second pattern is set as a background, the first pattern and the first pattern
The unit rectangular drawing line does not exist at the boundary portion of the drawing line structures of the adjacent patterns of the pattern, the second pattern and the second pattern, and the first pattern and the second pattern, and the first pattern, the first pattern, the 2 patterns, 2nd pattern and 1st
Around the boundary between the unit rectangle of the pattern and the second pattern,
Since the straight lines in the unit rectangle are not continuous and the number of lines in the unit rectangle is relatively small as compared with the first and second embodiments,
Since the print density is low and the same, the printed matter can be recognized only as a uniform background. However, when reproduced by a copying machine, the image line configuration of the first pattern causes image line thickening at the intersection portion, and the image line configuration of the second pattern causes image line thinning, so that the density difference remarkably appears. As a result, after copying,
A meaningful image appears against the background, and the latent image effect is greatly and clearly expressed.
