Description

  The present invention relates to a printed matter that requires prevention of counterfeiting or copying of securities such as banknotes, stock certificates, bonds, various certificates, and important documents.

  In general, various technologies have been applied to valuable printed matter of certificates in order to provide an effect of preventing forgery. However, in recent years, forgery of certificates has been accompanied by the improvement in image quality of color copiers and computerization of color platemaking technology. Technology tends to diversify. Along with this, we have responded by improving the anti-counterfeiting measures for certificates. However, on the other hand, if the manufacturing cost to spend on anti-counterfeiting measures is high, and it is expensive in authenticity judgment, such as introducing dedicated equipment consisting of special machinery and equipment, in order to obtain an environment for confirming the anti-counterfeiting effect was there.

  As a useful method for enabling authenticity determination at low cost, there is a technique for performing authenticity determination by overlaying a discriminator on a printed material. In other words, an invisible image is expressed as a visible image by overlaying a discriminating tool on a printed material on which an invisible image is applied. The main form of the discriminating tool is a transparent sheet printed with a parallel line screen (hereinafter referred to as “ten thousand”). Line filters ”), lenticular lenses, and the like. There are mainly two types of techniques for expressing an invisible image using this discriminator, and there are point phase modulation and line phase modulation.

  A printed material on which a latent image appears by superimposing such discriminating tools composed of line filters, and its true / false discrimination method include a background image portion printed with a line (or halftone) line, and a background image. There is a printed matter having a latent image portion printed with a line (or halftone dot) line having a phase different from that of the portion. The background image portion and the latent image portion of the printed matter are difficult to see at a glance, but when the line filter is superimposed on the printed matter at a predetermined position, the background image portion and the latent image portion are visible. A method is known in which a part can be divided and visually recognized.

  As an example of dot phase modulation (Dot phase modulation), a printed material on which a pattern phase-modulated in a first direction and a second direction is formed, a first direction of the printed material, and a line of a line filter The first multi-tone image formed by superimposing the line filters so as to match the direction of the line pattern and the angle at which the line filters are overlapped coincide with the second direction of the printed matter. In other words, there is a printed matter on which a second multi-tone image is formed and an image forming method (see, for example, Patent Document 1).

  In addition, as an example of dot phase modulation, each dot constituting a dot pattern in which an image appears by overlapping a lens array (fly eye lens, honeycomb lens, lenticular lens, etc.) on a base material. However, in a printed matter composed of at least two types of screen lines and at least two types of screen angle halftone dots, the dot area ratio of each dot constituting the dot pattern is the same if it is genuine. Therefore, an invisible image appears by overlapping the lens array, and in the case of a copy, the dots that are reproduced with the size of screen lines or the dot angle are crushed by copying and the dot density changes. There is a printed matter in which an image different from an invisible image appears (see, for example, Patent Document 2).

  As an example of overseas dot phase modulation, there is an isogram from Astron Design (Netherlands) (for example, see page 1340 of Non-Patent Document). In a flat pattern having a uniform density at first glance, an invisible image is formed by the phase of fine halftone dots when enlarged, and when a dedicated sheet is placed on the printed material, it is visible in either a negative or positive shape. An imaged invisible image appears. However, since this is a flat pattern having a uniform density, an image cannot be clearly expressed.

  In addition, the applicant of the present application has filed a patent application relating to a printed matter using dot phase modulation. This is a latent image printed matter in which a plurality of pixels of the same color are regularly arranged on a substrate to form two latent image patterns, and the phases of the plurality of pixels are shifted in the first direction. It has a first latent image pattern (invisible image) by the arranged first region and a second latent image pattern (invisible image) by the second region printed by the functional ink. (For example, refer to Patent Document 3).

  As an example of line phase modulation, the line phase is shifted by 1/2 pitch with respect to the line pattern having the line part and the non-line part on the base material and having the same pitch and width. A plurality of types of latent image line patterns provided with the formed latent image portions are printed matter having latent images that are printed by being overlapped at different angles, and the plurality of types of latent image line patterns are respectively colored. There is a printed matter characterized by a difference, and a latent image portion is made visible by superimposing a plurality of invisible images on a film having the same pitch as the line pattern of the printed matter (for example, Patent Document 4). reference).

  Moreover, HIT (Hidden Image Technology) of Yura (Hungary) is a printed material using overseas line phase modulation (see page 1341). An invisible image was given by the phase of fine lines in a flat pattern with a uniform density at first glance, and when a dedicated sheet was superimposed on the printed matter, it was visualized in either negative or positive form. An invisible image appears. In this method, since there is a possibility that an invisible image can be confirmed even with normal viewing, a visible image is provided by changing a part of the line width of a line as a camouflage pattern. Moreover, you may provide a visible image with a white drawing line. However, this camouflage pattern has a problem that when the invisible image is made visible by overlapping a dedicated sheet, the camouflage pattern also appears as a visible image at the same time. .

  In general, a pattern formed by dot phase modulation or line phase modulation has a flat shape.

  In addition, on the image forming sheet, the minimum unit blocks b1, b2, b3, b4,..., Which are equally divided into m columns and n rows in the unit block, are respectively set to 1 unit pixel g1, g2, g3, g4. Are formed as latent image images G1, G2, G3, G4,..., And unit pixels g1, g2, g3, g4,. A line pattern composed of lines, each line pitch p of pitches p1, p2, p3, p4,... And each line angle of angles θ1, θ2, θ3, θ4,. An anti-counterfeit image forming body composed of any one of the different line patterns composed of lines of θ, each unit pixel g1, g2, g3, g4,.・ The line pattern constituting the line, the line pitch p and the line angle θ of the same line The latent image images G1, G2, G3, G4,... Are visualized by superimposing the different line patterns composed of the line patterns for visualization formed on the transparent sheet. An anti-counterfeit image forming body has been proposed (see, for example, Patent Document 5).

  The anti-counterfeit image forming body according to Patent Document 5 visualizes a plurality of latent image images by changing the pitch and angle of the line pattern in each unit pixel. In addition, a transparent sheet that can only be expressed as a uniform background pattern, and further requires a pitch and an angle that match the line pattern of unit pixels constituting the latent image, in order to visualize the latent image. There was a problem that a plurality of discriminating tools had to be prepared.

  The inventors of the present application also include a first image line and a second image line arranged to face the center along the first direction, and a second direction orthogonal to the first direction. The image line elements having the third image line and the fourth image line arranged so as to face each other with the center as a boundary along the direction are arranged in a plurality of matrix shapes at a constant pitch. The first image line and the second image line, and the third image line and the fourth image line in the image line element are in a negative-positive relationship, and the first image line or the second image line is the first image line. An application has been filed for a forgery-preventing printed matter in which an invisible image is formed and a second invisible image is formed by the third image line or the fourth image line (see, for example, Patent Document 6). .

  The anti-counterfeit printed matter according to Patent Document 6 can provide a visible image in normal observation, has a rich design, has high visibility of a latent image in a simple discriminator, and can be manufactured at low cost. Although effective, it is not sufficient as a forgery prevention measure in high-resolution hard copy.

  Further, the inventors of the present application have arranged a plurality of sets of one first area and one second area adjacent to the first area as a forgery prevention measure in high-resolution hard copy, The periphery of the second region is surrounded by a plurality of the first regions, the first small region has a larger area than the second region, and the second region is a black containing an infrared absorbing dye. The second region of the second region formed by using the ink and the second region of the second region formed by using the ink that does not include the infrared absorbing dye, and the second region of the second region in each of the second regions. A halftone dot printed matter in which a gradation image is formed by the second area of the plurality of second areas according to the ratio of the second area to the second area has already been filed. (For example, refer to Patent Document 7).

  Furthermore, the inventors of the present application provide a first line drawing printed with a first color material that absorbs or emits light at a specific wavelength, and a first color material under visible light that does not absorb or emit light at the specific wavelength. A second line drawing printed with a second color material that appears to be the same color as the first line drawing, and the first line drawing and the second line drawing are each composed of a background area and a latent image area having different line widths, and The latent image area of the second line drawing has the same shape and size as the latent image area of the first line drawing, the first line drawing and the second line drawing overlap, and the density of the background area and the latent image area is equal. Have already filed applications for anti-counterfeit prints characterized by the above (for example, see Patent Document 8).

  Although the printed matter according to Patent Documents 7 and 8 has an excellent effect as a forgery prevention measure in a high-resolution hard copy, it has a special effect of determining the presence or absence of a color material that absorbs or emits light at a specific wavelength, for example, an infrared absorbing dye. Because of this, the discriminator becomes a special device composed of an optical mechanical part or a mechanical part that receives a specific electromagnetic wave, and there is a problem that simple discrimination as in Patent Documents 1 to 6 cannot be performed.

  Hereinafter, forgery prevention printed matter according to Embodiments 1 to 3 of the present invention will be described with reference to the drawings. However, the present invention is not limited to the first to third embodiments described below, and includes various other embodiments within the scope of the technical idea described in the claims. It is.

  The anti-counterfeit printed matter according to Embodiment 1 and Embodiment 2 of the present invention has two types of first authenticity determination method and second authenticity determination method, and the first authenticity determination As shown in FIG. 1, as a method, an invisible image is easily expressed by overlaying the discriminator 2 on the printed matter 1 or by viewing the image generated by the discriminator 4 as a second authenticity discrimination method. Thus, authenticity can be discriminated. The discriminating tool 2 of the first authenticity discrimination method is a line filter or a lenticular lens in which a plurality of straight lines are formed along a single line in a transparent filter. On the other hand, the discriminating tool 4 of the second authenticity discrimination method is an image input / display device (also referred to as an IR viewer) equipped with a camera (or an optical scanner) for infrared viewing.

  As shown in FIG. 1A, when the printed pattern 3 of the printed matter 1 is visually observed under normal visibility conditions, as shown in FIG. A visible image is visually recognized.

  Then, as a first authenticity discrimination method, when the discriminator 2 is superimposed on the printed matter 1 with a predetermined angle (this is assumed to be 0 degrees), the first as shown in FIG. One invisible image 5 is expressed as a visible image. As a result, the visible image of the printed pattern 3 shown in FIG. 1 is almost invisible, and the first invisible image 5 becomes a visible image and is observed to be replaced with the visible image of the printed pattern 3. Further, the invisible image 5 is visually recognized in a positive or negative state due to a difference in position where the discriminating tool 2 such as a line filter or a lenticular lens overlaps the printed pattern 3. What appears to be either negative or positive is caused by the relative position between the discriminator 2 and the printed material 1 and is within the scope of the effect of the present invention.

  Further, as a second authenticity determination method, when the infrared ray is viewed using the determination tool 4 that is an image input / display device equipped with a camera (or an optical scanner) that performs infrared observation on the printed matter 1, FIG. The second invisible image 6 as shown is expressed as a visible image. As a result, the visible image of the printed pattern 3 shown in FIG. 1 is almost invisible, and the second invisible image 6 becomes a visible image and is observed to be replaced with the visible image of the printed pattern 3.

(1) Embodiment 1
A forgery prevention printed matter according to Embodiment 1 of the present invention will be described.
FIG. 4A shows a partial enlargement in the configuration of one stroke of the printed pattern for the printed matter in Embodiment 1, and a configuration arranged in a matrix that forms the printed pattern 3 printed on the printed matter. It is the schematic diagram shown simply. Here, the vertical dimension Sv is 1 mm or less, for example, 340 μm. The image line in FIG. 4A is a minimum unit called a unit, and includes an image line A1, an image line A2, an image line A1 ′, and an image line A2 ′. The image lines shown in FIG. 4A are regularly arranged in a matrix on the surface of the printed material. The image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ form a pair and are in an on-off relationship with each other. For example, when one is black (on), the other is white (off), and when one is colored, the other is uncolored. Basically, both are black or both are white. It is not that. The image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ have the same area. The presence of the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ is not visually recognized under normal visibility conditions, and the image line A1 and / or the image line A2 An invisible image (negative or positive) is formed only by the image, and an invisible image (positive or negative) is formed only by the image line A1 ′ and / or the image line A2 ′. The term “the same area” as used in the present invention includes a case where the image area ratio is substantially the same.

  In addition, the image line C shown in FIG. 4A has the same or larger area as the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′. A visible image (design: pattern) is formed by the above, and an image line constituting the visible image of the printed pattern 3 composed of arbitrary figures and characters as shown in FIG. 2 is formed, and the image line C is the image line A1 and / or It is arranged so as to be sandwiched between the image line A2 and the image line A1 ′ and / or the image line A2 ′. Further, the image line C shown in FIG. 4A is a rectangle having the horizontal direction of the unit as the longitudinal direction and the dimension Sh as the maximum width. That is, the region having the image line C is connected in a horizontal straight line by the vicinity of the unit.

  In FIG. 4A, the boundaries between the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ are indicated by gradations. It shows that the area of the image line A2 and / or the image line A1 ′ and / or the image line A2 ′ varies depending on the configuration of the second invisible image 6. That is, the ratio of the respective areas of the image line A1 and / or the image line A2 and the image line A1 'and / or the image line A2' varies depending on the continuous tone constituting the second invisible image 6.

  The image line A1 and / or the image line A2 and the image line A1 'and / or the image line A2' are visually recognized as black in the wavelength range of visible light. The image line A1 and the image line A1 ′ are made of a color material containing an infrared absorbing dye, for example, black (Bk) ink, and the image line A2 and the image line A2 ′ are a color material not containing an infrared absorbing dye, for example, It is composed of ink mixed by subtractive color mixture of cyan (C), magenta (M), and yellow (Y). In the present embodiment, the continuous gradation of the second invisible image 6 is composed of the image line A1 and the image line A1 ', and is composed of a color material containing an infrared absorbing dye. A specific image line configuration will be described in detail later.

  The printed pattern 3 of the printed matter 1 shown in FIG. 2 is a regular and regular pattern in which the unit shown in FIG. 4A has a vertical step number v and a horizontal step number h in a matrix without vertical and horizontal gaps. Is arranged. The number of steps referred to in the present embodiment refers to the number of units repeated on the printed pattern 3, and the number of steps is not limited at all, and the resolution of the visible image and the invisible image depends on the number of steps. It is proportional. Further, the parallel lines composed of the group of the image lines A1 and / or the image line A2 by arranging the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ in the horizontal direction, A parallel line composed of the image line A1 ′ and / or the image line A2 ′ group is formed. That is, FIG. 4 shows a state in which an invisible image is applied by line phase modulation. However, in this state, a plurality of image lines A1 and / or image lines A2 and a plurality of image lines A1 ′ and / or image lines A2 ′ are visually imaged in the vicinity of a unit arranged in a matrix. When both A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ are turned on (colored), the density looks high (darker), or a plurality of image lines A1 and The image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 near the unit in which the image lines A1 ′ and / or the image line A2 ′ are arranged in a matrix. In some cases, both the image line A2 ′ and the image line A2 ′ are turned off (no coloration), so that the density may appear low (light), and the density may appear to be unbalanced with the naked eye.

  In order to alleviate the appearance of this density imbalance, the image line E1 and / or the image line E2 and the image line a1 and / or the image line a2 shown in FIG. Arranged in the area. The image line a1 and / or the image line a2 are half the image line area of the image line A1 and / or the image line A2, and are arranged in the unit vertical direction with respect to the image line A1 and / or the image line A2. They are arranged so as to be sandwiched between the line A1 ′ and / or the image line A2 ′ and the image line A1 ′ and / or the image line A2 ′. On the other hand, the image line E1 and / or the image line E2 has an image area that is half of the image line A and / or the image line A ′, and is higher in the unit vertical direction than the image line A1 ′ and / or the image line A2 ′. Are arranged so as to be sandwiched between the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′. Thereby, the imbalance between the image line for the first invisible image 5 and the density is alleviated. The image line E1 and the image line a1 are made of a color material containing an infrared absorbing dye, for example, black (Bk) ink, and the image line E2 and the image line a2 are a color material not containing an infrared absorbing dye. For example, the ink is composed of ink mixed by subtractive color mixture of cyan (C), magenta (M), and yellow (Y).

  The deletion and addition of the strokes are executed for each unit [h, v] which is the minimum unit by the algorithm shown in FIG. Here, in order to simplify the notation of the drawing, the drawing line A1 and / or the drawing line A2 are collectively referred to as the drawing line A, and the drawing line A1 ′ and / or the drawing line A2 ′ are collectively referred to as the drawing line A ′, and the drawing line E1. And / or the image line E2 is collectively referred to as the image line E, and the image line a1 and / or the image line a2 are generally described as the image line a. Note that [v] is the number of steps when the unit is counted from the top, and [h] is the number of steps when the unit is counted from the left and right. First, in process f1, the image line A [h, v] and the image line A ′ [h, v] are sequentially detected in the unit [h, v] for each column arranged in a matrix. The method for detecting the image line A [h, v] and the image line A ′ [h, v] is, for example, when the print pattern 3 is a binary image in the bitmap format, in the unit to be processed. The image line A [h, v] and / or the image line A ′ [h, v] may be identified by a process generally called labeling.

  Next, in process f2, the condition is satisfied that the unit [h, v] has the image line A ′ [h, v] and the unit [h, v + 1] has the image line A [h, v + 1]. Then, in process f3, the image line A ′ [h, v], which is the position where the unit [h, v] is originally arranged, is deleted. That is, as shown in FIG. 6A, when the unit [h, v], the unit [h, v + 1], and the unit [h, v + 2] are arranged, the line A of the unit [h, v] 'When [h, v] and the image line A [h, v + 1] of the unit [h, v + 1] are adjacent, the image of the unit [h, v] is displayed as shown in FIG. The line A ′ [h, v] is deleted. If the condition of the process f2 is not met, the process proceeds to process 4.

  Next, in process f4, the condition is satisfied that the unit [h, v] has the image line A [h, v] and the unit [h, v + 1] has the image line A ′ [h, v + 1]. In step f5, the image line a [h, v] in the unit [h, v] is added. That is, as shown in FIG. 7B, an image line having an image area that is half of the image line A and / or the image line A ′ between the unit [h, v] and the unit [h, v + 1]. a is added. Thereby, the density imbalance in the naked eye between the unit [h, v] and the unit [h, v + 1] is alleviated. In addition, the half line area referred to in the present invention includes substantially half the line area.

  Next, in process f6, the unit [h, v] has the image line A ′ [h, v], the unit [h, v + 1] has no image line, and the unit [h, v + 2] has the image line. When the condition having the line A [h, v + 2] is met, the image line E1 and / or the image line E2 [h, v + 1] in the unit [h, v + 1] is added in the process f7. That is, as shown in FIG. 7C, the image line A and / or the image line A ′ is located in an area adjacent to the position where the image line A [h, v + 1] of the unit [h, v + 1] is arranged. The image line E1 and / or the image line E2 having a half image area are added. Thereby, the density imbalance in the naked eye between the unit [h, v] and the unit [h, v + 2] is alleviated.

  Next, in process f8, the unit [h, v] has the image line A ′ [h, v], the unit [h, v + 1] has no image line, and the unit [h, v + 2] has the image line. When the condition having the line A ′ [h, v + 2] is met, the image line E1 and / or the image line E2 [h, v + 1] in the unit [h, v + 1] and the image line a [h, v + 1] is added. That is, as shown in FIG. 7D, the image line A and / or the image line A ′ is located at a position adjacent to the area where the image line A [h, v + 1] of the unit [h, v + 1] is arranged. The image line A1 and / or the image line E2 having a half image area are added, and the image line A is positioned adjacent to the region where the image line A ′ [h, v + 1] of the unit [h, v + 1] is arranged. And / or a drawing line a having a drawing area half that of the drawing line A ′ is added. Thereby, the density imbalance in the naked eye between the unit [h, v] and the unit [h, v + 2] is alleviated.

  In this state, for example, the discriminating tool 2 made of a lenticular lens is overlaid on the printed pattern 3 on the printed matter 1 and visually observed from the front, whereby an invisible image applied to the printed pattern 3 is expressed as a visible image. be able to. In the first embodiment, the dimension Sv is 340 μm, and the printed pattern 3 is printed on the coated paper by offset printing. However, the dimension Sv, the substrate of the printed material, the printing method, the printing material, the printing apparatus, and the like are not limited at all.

  Here, in order to briefly describe the first embodiment, the first invisible image 5 shown in FIG. 3A and the second invisible image 6 shown in FIG. This will be explained with a schematic expression. FIG. 8A shows a case where, for example, the letter “a” is used as an image that becomes the basis of the visible image in the area of the printed pattern 3. On the other hand, FIG. 8B uses, for example, the letter “A” as the image that is the basis of the first invisible image. In addition, as an image that is the basis of the second invisible image, for example, a gentle continuous tone is expressed. Although the resolution of the visible image is not particularly limited, as a method for further enhancing the effect of the present embodiment, as the minimum pixel size of the image, the image shown in FIG. Each half of the horizontal dimension Sh is suitable. In addition, as for the resolution of the first invisible image and the second invisible image shown in FIG. 8B, it is appropriate that the vertical dimension Sv and the horizontal dimension Sh of the unit match each other. . Hereinafter, the present embodiment will be described in detail based on the image shown in FIG.

  FIG. 9A shows the visual image shown in FIG. 8A constituted by the drawing lines C shown in FIG. 4A, and the difference in size of the drawing lines arranged in a matrix. Is used to express the letter “a”. Since the minimum pixel size of the image is half of the vertical dimension Sv and the horizontal dimension Sh of the unit, the visible image formed by the image line C is the first invisible shown in FIG. The resolution is double that of the image and the second invisible image. The image line C is printed with a color material that does not contain an infrared-absorbing dye, such as cyan (C), magenta (M), yellow (Y), or a mixed ink. On the other hand, FIG. 9B shows the arrangement of image lines constituting the first invisible image and the second invisible image. According to the algorithm shown in FIG. 5, the drawing line arrangement is such that the character “A”, which is the first invisible image shown in FIG. 8B, is embedded. Furthermore, the second invisible image is included in the first invisible image. That is, the image line E1, the image line A2, the image line A1 ′, and the image line A2 ′ shown in FIG. It is comprised by the line a1 and / or the drawing line a2.

  The image line configuration shown in FIG. 9B will be described in more detail with reference to FIG. FIG. 10A shows a group of image lines composed of a color material containing an infrared absorbing pigment, for example, black (Bk) ink. The image lines A1, A1 ′, E1 and The line a1 represents, for example, a gentle continuous tone as the image that is the basis of the second invisible image shown in FIG. 8B. On the other hand, FIG. 10B shows a group of image lines composed of a color material that does not contain an infrared absorbing pigment, for example, ink mixed by subtractive color mixing of cyan (C), magenta (M), and yellow (Y). The negative state of the image that is the basis of the second invisible image shown in FIG. 8B is represented by the image line A2, the image line A2 ′, the image line E2, and the image line a2. It is a thing. A combination of the image line group in FIG. 10 (a) and the image line group in FIG. 10 (b) is the image line group in FIG. 11 (b).

  The printed pattern 3 shown in FIG. 11A is a combination of the invisible image shown in FIG. 9A and the invisible image shown in FIG. First, as a first authenticity determination method, as shown in FIG. 11A, the center line 7 of each lens in the lenticular lens as the determination tool 2 is drawn at a predetermined position on the printed material. It is placed so as to coincide with the center of the image line A2, that is, the line L1 in FIG. In this case, as shown in FIG. 11B, the image line A1 and the image line A2 are enlarged by the action of the lenticular lens, so that the image (pattern) formed by the image line A1 and the image line A2 is displayed. ) Can be confirmed. At this time, the image line C constituting the visible image does not coincide with the center line 7 of each lens of the lenticular lens, and is not viewed from directly above the discriminator 2. As a result, the visible image of the printed pattern 3 shown in FIG. 2 is switched to the first invisible image 5 as shown in FIG. When the center line 7 of each lens of the discriminator 2 is moved along the vertical axis direction so as to coincide with the line L2 in FIG. 4 so that the image line A1 ′ and the image line A2 ′ are enlarged. The first invisible image visually recognized by the image line A1 ′ and the image line A2 ′ is visually recognized with negative-positive reversal.

  The printed pattern 3 shown in FIG. 12A is a combination of the invisible image shown in FIG. 9A and the invisible image shown in FIG. 9B. First, as a second authenticity determination method, when the infrared ray is viewed using a determination tool 4 as shown in FIG. 1, for example, an image input / display device equipped with a camera (or an optical scanner) for infrared viewing, The second invisible image as shown in FIG. 12B is expressed as a visible image. That is, when viewed with infrared rays, the image line C, the image line A2, the image line A2 ′, the image line E2, and the image line a2 that do not contain an infrared absorbing pigment are only reflected on the surface of the substrate of the printed matter 1, and absorb infrared rays. Only the image line A1, the image line A1 ′, the image line E1, and the image line a1 containing the sex pigment are confirmed, and the second invisible image is observed as a visible image. That is, in the infrared vision, the image line including the infrared absorbing pigment and the image line not including the infrared absorbing pigment are in an on-off relationship with each other. Image line A1, image line A1 ′, image line E1 and image line a1 made of a color material containing an infrared absorbing dye are black (on), and image line C and image made of a color material containing no infrared absorbing dye. The line A2, the image line A2 ′, the image line E2, and the image line a2 are recognized as white (off), and basically, both are not black or both are white. Thus, the forgery prevention printed matter is provided with a different first authenticity determination method and second authenticity determination method. As the number of units arranged in a matrix increases, the resolution of the image becomes higher, and the second invisible image 6 as shown in FIG. 3B can be expressed.

  Further, the unit configuration may be an image line configuration shown in FIG. FIG. 4B shows an image line E1 and / or an image line E2 and an image line a1 and / or an image line a2 for alleviating that the concentration shown in FIG. Are arranged so as to be sandwiched between the image line C regions. That is, the image line a1 and / or the image line a2 and the image line E1 and / or the image line E2 shown in FIG. 4B are the image line A1 and / or the image line A2 and the image line A1 ′ and In other words, they are arranged with a half length of the dimension Sh in the lateral direction of the unit with respect to the image line A2 ′. The image line a1 and / or the image line a2 is an image area that is half of the image line A1 and / or the image line A2, and is arranged in the unit vertical direction with respect to the image line A1 and / or the image line A2, and is a matrix. Are arranged so as to be sandwiched between the image line A1 ′ and / or the image line A2 ′ and the image line A1 ′ and / or the image line A2 ′ in the vicinity of the unit arranged in a shape. On the other hand, the image line E1 and / or the image line E2 and the image line E1 and / or the image line E2 have an image area that is half of the image line A and / or the image line A ′, and the image lines A1 ′ and / or Alternatively, it is arranged in the vertical direction of the unit with respect to the image line A2 ′, and in the vicinity of the unit arranged in a matrix, the image line A1 and / or the image line A2 and the image line A1 and / or the image line A2 It is arranged to be sandwiched. Thus, the image lines for reducing the density imbalance of the image lines for the first invisible image are connected in a horizontal straight line in the unit horizontal direction. The same effect can be achieved in the image line configuration of the unit shown in FIG.

  The printed pattern 3 shown in FIG. 16A is a combination of the invisible image shown in FIG. 14A and the invisible image shown in FIG. First, as a first authenticity determination method, as shown in FIG. 16A, the center line 7 of each lens in the lenticular lens as the determination tool 2 is drawn at a predetermined position on the printed matter as the image line A1 and It is placed so as to coincide with the center of the image line A2, that is, the line L1 in FIG. In this case, as shown in FIG. 16B, the image line A1 and the image line A2 are enlarged by the action of the lenticular lens, and therefore “A” configured by the image line A1 and the image line A2. Will be confirmed. At this time, the image line C constituting the visible image does not coincide with the center line 7 of each lens of the lenticular lens, and is not viewed from directly above the discriminator 2. When the center line 7 of each lens of the discriminator 2 is moved along the vertical axis direction so as to coincide with the line L2 in FIG. 4 so that the image line A1 ′ and the image line A2 ′ are enlarged. The first invisible image visually recognized by the image line A1 ′ and the image line A2 ′ is visually recognized with negative-positive reversal.

In this case, as shown in FIG. 17B, the image line B1 and the image line A2 are enlarged by the action of the lenticular lens, and therefore, “B” constituted by the image line B1 and the image line B2. Will be confirmed. At this time, the image line C constituting the visible image does not coincide with the center line 7 of each lens of the lenticular lens, and is not viewed from directly above the discriminator 2. When the center line 7 of each lens of the discriminator 2 is moved along the vertical axis direction so as to coincide with the line L4 in FIG. 4 so that the image line B1 ′ and the image line B2 ′ are enlarged. The third invisible image visually recognized by the image line B1 ′ and the image line B2 ′ is viewed with the negative-positive reversal.

  The printed pattern 3 shown in FIG. 18A is a combination of the invisible image shown in FIG. 14A and the invisible image shown in FIG. First, as a second authenticity determination method, when the infrared ray is viewed using a determination tool 4 as shown in FIG. 1, for example, an image input / display device equipped with a camera (or an optical scanner) for infrared viewing, The second invisible image as shown in FIG. 18B is expressed as a visible image. That is, when viewed with infrared rays, the line C, the line A2, the line A2 ′, the line B2, the line B2 ′, the line E2, the line a2, and the line 2B that do not include the infrared absorbing pigment are printed matter.

Two invisible images are observed as visible images. Thus, the forgery prevention printed matter is provided with a different first authenticity determination method and second authenticity determination method.

  Here, regardless of the lenticular lens, the discriminator 2 can obtain the same effect even if it is a line filter, for example. In the case of this line filter, the portion corresponding to the line on the filter hides the line that forms the visible image, so that only the line that forms the invisible image can be confirmed. The image may not be completely concealed and may be slightly recognized. However, since this does not impair the effect of the present invention, it is sufficient to use a line filter for simple discrimination.

  The image line C constituting the visible image according to the first and second embodiments has a design property and is a relative photographic scale colored with an appropriate density in terms of halftone dots and gray scale in addition to a single color pattern. A continuous tone image composed of a known expression method such as a tone or random dot dither method can be applied.

  In step f3, the invisible information 13 is obtained by the first invisible information input means M2. The information that can be input may be an image or text. When obtaining invisible information data in text, the editing means M6 converts it into a bitmap binary image. At this time, it is configured with the same number of pixels as the bitmap multi-valued image. Next, in step f4, a first invisible image arranged in the area of the image line A1 and the image line A1 'shown in FIG. 4 is constructed. Conversion to the data of the image line A1 and the data of the image line A1 'is performed by the invisible image forming unit M6b included in the editing unit M6 shown in FIG.

  FIG. 23 shows a state where authenticity determination is performed using the determination tool 2 and the determination tool 4 on the printed matter 8 of the identification card. As a result, when the first discriminating tool is used for the invisible image portion 11, the first invisible image can be visually recognized as a visible image, and when the invisible image portion 11 is used for the second discriminating tool, The two invisible images can be visually recognized as visible images. FIG. 23A shows a state in which the first discriminating tool 2 using a lenticular lens is overlaid on the invisible image portion 11 of the identification type printed matter 8. The time stamp information of the invisible information 13 appears by the first discriminator 2. On the other hand, FIG. 23B shows the invisible image portion 11 of the identification-type printed matter 8 using the second discriminating tool by an image input / display device equipped with a camera (or optical scanner) for infrared viewing.

  The present invention relates to a printed matter that requires prevention of counterfeiting or copying of securities such as banknotes, stock certificates, bonds, various certificates, and important documents.

  In general, various technologies have been applied to valuable printed matter of certificates in order to provide an effect of preventing forgery. However, in recent years, forgery of certificates has been accompanied by the improvement in image quality of color copiers and computerization of color platemaking technology. Technology tends to diversify. Along with this, we have responded by improving the anti-counterfeiting measures for certificates. However, on the other hand, if the manufacturing cost to spend on anti-counterfeiting measures is high, and it is expensive in authenticity judgment, such as introducing dedicated equipment consisting of special machinery and equipment, in order to obtain an environment for confirming the anti-counterfeiting effect was there.

  As a useful method for enabling authenticity determination at low cost, there is a technique for performing authenticity determination by overlaying a discriminator on a printed material. In other words, an invisible image is expressed as a visible image by overlaying a discriminating tool on a printed material on which an invisible image is applied. The main form of the discriminating tool is a transparent sheet printed with a parallel line screen (hereinafter referred to as “ten thousand”). Line filters ”), lenticular lenses, and the like. There are mainly two types of techniques for expressing an invisible image using this discriminator, and there are point phase modulation and line phase modulation.

  A printed material on which a latent image appears by superimposing such discriminating tools composed of line filters, and its true / false discrimination method include a background image portion printed with a line (or halftone) line, and a background image. There is a printed matter having a latent image portion printed with a line (or halftone dot) line having a phase different from that of the portion. The background image portion and the latent image portion of the printed matter are difficult to see at a glance, but when the line filter is superimposed on the printed matter at a predetermined position, the background image portion and the latent image portion are visible. A method is known in which a part can be divided and visually recognized.

  As an example of dot phase modulation (Dot phase modulation), a printed material on which a pattern phase-modulated in a first direction and a second direction is formed, a first direction of the printed material, and a line of a line filter The first multi-tone image formed by superimposing the line filters so as to match the direction of the line pattern and the angle at which the line filters are overlapped coincide with the second direction of the printed matter. In other words, there is a printed matter on which a second multi-tone image is formed and an image forming method (see, for example, Patent Document 1).

  In addition, as an example of dot phase modulation, each dot constituting a dot pattern in which an image appears by overlapping a lens array (fly eye lens, honeycomb lens, lenticular lens, etc.) on a base material. However, in a printed matter composed of at least two types of screen lines and at least two types of screen angle halftone dots, the dot area ratio of each dot constituting the dot pattern is the same if it is genuine. Therefore, an invisible image appears by overlapping the lens array, and in the case of a copy, the dots that are reproduced with the size of screen lines or the dot angle are crushed by copying and the dot density changes. There is a printed matter in which an image different from an invisible image appears (see, for example, Patent Document 2).

  As an example of overseas dot phase modulation, there is an isogram from Astron Design (Netherlands) (for example, see page 1340 of Non-Patent Document). In a flat pattern having a uniform density at first glance, an invisible image is formed by the phase of fine halftone dots when enlarged, and when a dedicated sheet is placed on the printed material, it is visible in either a negative or positive shape. An imaged invisible image appears. However, since this is a flat pattern having a uniform density, an image cannot be clearly expressed.

  In addition, the applicant of the present application has filed a patent application relating to a printed matter using dot phase modulation. This is a latent image printed matter in which a plurality of pixels of the same color are regularly arranged on a substrate to form two latent image patterns, and the phases of the plurality of pixels are shifted in the first direction. It has a first latent image pattern (invisible image) by the arranged first region and a second latent image pattern (invisible image) by the second region printed by the functional ink. (For example, refer to Patent Document 3).

  As an example of line phase modulation, the line phase is shifted by 1/2 pitch with respect to the line pattern having the line part and the non-line part on the base material and having the same pitch and width. A plurality of types of latent image line patterns provided with the formed latent image portions are printed matter having latent images that are printed by being overlapped at different angles, and the plurality of types of latent image line patterns are respectively colored. There is a printed matter characterized by a difference, and a latent image portion is made visible by superimposing a plurality of invisible images on a film having the same pitch as the line pattern of the printed matter (for example, Patent Document 4). reference).

  Moreover, HIT (Hidden Image Technology) of Yura (Hungary) is a printed material using overseas line phase modulation (see page 1341). An invisible image was given by the phase of fine lines in a flat pattern with a uniform density at first glance, and when a dedicated sheet was superimposed on the printed matter, it was visualized in either negative or positive form. An invisible image appears. In this method, since an invisible image may be confirmed even with normal viewing, a visible image is provided by changing a part of the line width of the line as a camouflage pattern. Moreover, you may provide a visible image with a white drawing line. However, this camouflage pattern has a problem that when the invisible image is made visible by overlapping a dedicated sheet, the camouflage pattern also appears as a visible image at the same time. .

  In general, a pattern formed by dot phase modulation or line phase modulation has a flat shape.

  In addition, on the image forming sheet, the minimum unit blocks b1, b2, b3, b4,..., Which are equally divided into m columns and n rows in the unit block, are respectively set to 1 unit pixel g1, g2, g3, g4. Are formed as latent image images G1, G2, G3, G4,..., And unit pixels g1, g2, g3, g4,. A line pattern composed of lines, each line pitch p of pitches p1, p2, p3, p4,... And each line angle of angles θ1, θ2, θ3, θ4,. An anti-counterfeit image forming body composed of any one of the different line patterns composed of lines of θ, each unit pixel g1, g2, g3, g4,.・ The line pattern constituting the line, the line pitch p and the line angle θ of the same line The latent image images G1, G2, G3, G4,... Are visualized by superimposing the different line patterns composed of the line patterns for visualization formed on the transparent sheet.

The image line in FIG. 4A is a minimum unit called a unit, and includes an image line A1, an image line A2, an image line A1 ′, and an image line A2 ′. The image lines shown in FIG. 4A are regularly arranged in a matrix on the surface of the printed material. The image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ form a pair and are in an on-off relationship with each other. The relationship between the on-off, for example, black or both of the other is white (off), and the other Ru uncolored der when one is chromatic coloring, in both basically when the one is black (on) Both are never white. The image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ have the same area. The presence of the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ is not visually recognized under normal visibility conditions, and the image line A1 and / or the image line A2 An invisible image (negative or positive) is formed only by the image, and an invisible image (positive or negative) is formed only by the image line A1 ′ and / or the image line A2 ′. The term “the same area” as used in the present invention includes a case where the image area ratio is substantially the same.

  In addition, the image line C shown in FIG. 4A has the same or larger area as the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′. A visible image (design: pattern) is formed by the above, and an image line constituting the visible image of the printed pattern 3 composed of arbitrary figures and characters as shown in FIG. 2 is formed. Or it arrange | positions so that it may be pinched | interposed into image line A2, image line A1 ', and / or image line A2'. Further, the image line C shown in FIG. 4A is a rectangle having the horizontal direction of the unit as the longitudinal direction and the dimension Sh as the maximum width. That is, the region including the image line C is connected in a horizontal straight line by the vicinity of the unit.

  In FIG. 4A, the boundaries between the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ are indicated by gradations. It shows that the area of the image line A2 and / or the image line A1 ′ and / or the image line A2 ′ varies depending on the configuration of the second invisible image 6. That is, the ratio of the respective areas of the image line A1 and / or the image line A2 and the image line A1 'and / or the image line A2' varies depending on the continuous tone constituting the second invisible image 6.

The image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ are visually recognized as black in the wavelength region of visible light. The image line A1 and the image line A1 ′ are composed of , for example , black (Bk) ink containing carbon black as a color material including an infrared absorbing dye, and the image line A2 and the image line A2 ′ are made of an infrared absorbing dye. The color material not included is , for example , black mixed by subtractive color mixing of cyan (C), magenta (M), and yellow (Y). In the present embodiment, since the continuous tone of the second invisible image 6 is formed by the image line A1 and the image line A1 ′, the second invisible image 6 is composed of a color material containing an infrared absorbing dye. A specific image line configuration will be described in detail later.

  The printed pattern 3 of the printed matter 1 shown in FIG. 2 is a regular and regular pattern in which the unit shown in FIG. 4A has a vertical step number v and a horizontal step number h in a matrix without vertical and horizontal gaps. Is arranged. The number of steps referred to in the present embodiment refers to the number of units repeated on the printed pattern 3, and the number of steps is not limited at all, and the resolution of the visible image and the invisible image depends on the number of steps. It is proportional. Further, the parallel lines composed of the group of the image lines A1 and / or the image line A2 by arranging the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ in the horizontal direction, A parallel line composed of the image line A1 ′ and / or the image line A2 ′ group is formed. That is, FIG. 4 shows a state in which an invisible image is applied by line phase modulation. However, in this state, a plurality of image lines A1 and / or image lines A2 and a plurality of image lines A1 ′ and / or image lines A2 ′ are visually viewed in the vicinity of the unit arranged in a matrix. When both the line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′ are turned on (colored), the density looks high (darker), or a plurality of image lines A1. And / or the drawing line A2 and the drawing line A1 and / or the drawing line A2 and the drawing line A1 ′ in the vicinity of the unit in which the plurality of drawing lines A1 ′ and / or the drawing line A2 ′ are arranged in a matrix. In addition, when both the image A2 ′ and the image line A2 ′ are turned off (uncolored), the density may appear low (light), and the density may appear to be unbalanced with the naked eye.

In order to alleviate the appearance of this density imbalance, the image line E1 and / or the image line E2 and the image line a1 and / or the image line a2 shown in FIG. Arranged in the area. The image line a1 and / or the image line a2 is an image area that is half of the image area that is the sum of the image lines A1 and / or the image line A2 in one unit , and the image line A1 and / or the image line A2 On the other hand, they are arranged in the vertical direction of the unit and are arranged so as to be sandwiched between the image line A1 ′ and / or the image line A2 ′ and the image line A1 ′ and / or the image line A2 ′. On the other hand, streaked E1 and / or streaking E2 are streaked area of half of the streaked area which is the sum of streaking A 1 and / or streaked A 2 in the one unit, streaked A1 'and / Alternatively, they are arranged in the unit longitudinal direction with respect to the image line A2 ′, and are arranged so as to be sandwiched between the image line A1 and / or the image line A2 and the image line A1 ′ and / or the image line A2 ′. Thereby, the imbalance between the image line and the density of the first invisible image 5 is alleviated. The image line E1 and the image line a1 are composed of , for example , black (Bk) ink containing carbon black as a color material including an infrared absorbing dye, and the image line E2 and the image line a2 are infrared absorbing dyes. As a color material that does not include , for example , it is composed of black mixed by subtractive color mixture of cyan (C), magenta (M), and yellow (Y).

Here, in order to simplify the notation of the drawing, the drawing line A1 and / or the drawing line A2 are collectively referred to as the drawing line A, and the drawing line A1 ′ and / or the drawing line A2 ′ are collectively referred to as the drawing line A ′, and the drawing line E1. And / or the image line E2 is collectively referred to as the image line E, and the image line a1 and / or the image line a2 are generally described as the image line a. Note that [v] is the number of steps obtained by counting units from the top. First, in process f1, the image line A [v] and the image line A '[v] are sequentially detected in the unit [v] for each column arranged in a matrix. Note that the method of detecting the image line A [v] and the image line A ′ [v] is generally labeled in a unit to be processed when the print pattern 3 is a binary image in the bitmap format, for example. The image line A [v] and / or the image line A ′ [v] may be identified by a process called “”.

  Next, in process f2, when the condition of having the image line A ′ [v] in the unit [v] and the image line A [v + 1] in the unit [v + 1] is met, in the process f3, The image line A ′ [v], which is the position where the unit [v] is originally arranged, is deleted. That is, as shown in FIG. 6A, when the unit [v], the unit [v + 1], and the unit [v + 2] are arranged, the line A ′ [v] and the unit [v + 1] of the unit [v] ], The image line A ′ [v] of the unit [v] is deleted, as shown in FIG. 6B. If the condition of the process f2 is not met, the process proceeds to process 4.

Next, in process f4, when the condition that the unit [v] has the image line A [v] and the unit [v + 1] has the image line A ′ [v + 1] is satisfied, the process f5 The image line a [v] is added in the unit [v]. That is, as shown in FIG. 7B, an image half of the image line A and / or the image line A ′ is placed between the image line A of the unit [v] and the image line A ′ of the unit [v + 1]. An image line a having a line area is added. This alleviates the density imbalance between the unit [v] and the unit [v + 1] with the naked eye. In addition, the half line area referred to in the present invention includes substantially half the line area.

In step f7, the image line E1 [v + 1] is added in the unit [v + 1]. That is, as shown in FIG. 7C, the image line A and / or the image line is intermediate between the image line A ′ [v + 1] of the unit [v + 1] and the image line A ′ [v + 2] of the unit [v + 2]. A drawing line E1 having a drawing area half that of A ′ is added. This alleviates the density imbalance between the unit [v] and the unit [v + 2] with the naked eye.

  Next, in process f8, the unit [v] has the image line A ′ [v], the unit [v + 1] has no image line, and the unit [v + 2] has the image line A ′ [v + 2]. When the conditions are met, the image line E [v + 1] and the image line a [v + 1] in the unit [v + 1] are added in the process f9. That is, as shown in FIG. 7 (d), the image line A and / or the image line A 'is half the position adjacent to the area where the image line A [v + 1] of the unit [v + 1] is arranged. The image line E having an area is added, and the image line area half of the image line A and / or the image line A ′ is set at a position adjacent to the region where the image line A ′ [v + 1] of the unit [v + 1] is arranged. The image line a having is added. This alleviates the density imbalance between the unit [v] and the unit [v + 2] with the naked eye.

In this state, for example, the first discriminating tool 2 made of a lenticular lens is superimposed on the printed pattern 3 on the printed material 1 and visually observed from the front, whereby an invisible image applied to the printed pattern 3 is visualized. Can be expressed as In the first embodiment, the dimension Sv is 340 μm, and the printed pattern 3 is printed on the coated paper by offset printing. However, the dimension Sv, the substrate of the printed material, the printing method, the printing material, the printing apparatus, and the like are not limited at all.

  Here, in order to briefly describe the first embodiment, the first invisible image 5 shown in FIG. 3A and the second invisible image 6 shown in FIG. This will be explained with a schematic expression. FIG. 8A shows a case where, for example, the letter “a” is used as an image that becomes the basis of the visible image in the area of the printed pattern 3. On the other hand, FIG. 8B uses, for example, the letter “A” as the image that is the basis of the first invisible image. In addition, as an image that is the basis of the second invisible image, for example, a gentle continuous tone is expressed. Although the resolution of the visible image is not particularly limited, as a method for further enhancing the effect of the present embodiment, as the minimum pixel size of the image, the image shown in FIG. Each half of the horizontal dimension Sh is suitable. In addition, as for the resolution of the first invisible image and the second invisible image shown in FIG. 8B, it is appropriate that the vertical dimension Sv and the horizontal dimension Sh of the unit match each other. . Hereinafter, the present embodiment will be described in detail based on the image shown in FIG.

FIG. 9A shows the visual image shown in FIG. 8A constituted by the drawing lines C shown in FIG. 4A, and the difference in size of the drawing lines arranged in a matrix. Is used to express the letter “a”. Since the minimum pixel size of the image is half of the vertical dimension Sv and the horizontal dimension Sh of the unit, the visible image formed by the image line C is the first invisible shown in FIG. The resolution is double that of the image and the second invisible image. Further, streaking C is as a coloring material that does not contain an infrared absorbing dye, for example, cyan (C), either alone magenta (M) and yellow (Y), or printed them were mixed ink Yes. On the other hand, FIG. 9B shows the arrangement of image lines constituting the first invisible image and the second invisible image. According to the algorithm shown in FIG. 5, the drawing line arrangement is such that the character “A”, which is the first invisible image shown in FIG. 8B, is embedded. Furthermore, the second invisible image is included in the first invisible image. That is, the image line E1, the image line A2, the image line A1 ′, and the image line A2 ′ shown in FIG. It is comprised by the line a1 and / or the drawing line a2.

The image line configuration shown in FIG. 9B will be described in more detail with reference to FIG. FIG. 10A shows an image line group composed of , for example , black (Bk) ink including carbon black as a color material including an infrared absorbing pigment. The image line A1 and the image line A1 ′ are shown in FIG. The image E1 and the image a1 represent, for example, a gentle continuous tone as an image that is the basis of the second invisible image shown in FIG. 8B. On the other hand, FIG. 10B shows an image line composed of black mixed by subtractive color mixing of , for example , cyan (C), magenta (M), and yellow (Y) as a color material that does not contain an infrared absorbing dye. A group is shown, and the negative state of the image that is the basis of the second invisible image shown in FIG. 8B is indicated by the drawing line A2, the drawing line A2 ′, the drawing line E2, and the drawing line a2. It is expressed. 10 those with together streaking group image lines and FIG. 10 (b) of (a) is that streaking group in FIG. 9 (b).

The printed pattern 3 shown in FIG. 11A is a combination of the visible image shown in FIG. 9A and the invisible image shown in FIG. 9B. First, as a first authenticity determination method, as shown in FIG. 11A, the center line 7 of each lens in the lenticular lens as the first determination tool 2 is displayed at a predetermined position on the printed material. It is placed so as to coincide with the center of the line A1 and the image line A2, that is , the line L1 in FIG. In this case, as shown in FIG. 11B, the image line A1 and the image line A2 are enlarged by the action of the lenticular lens, so that the image (pattern) formed by the image line A1 and the image line A2 is displayed. ) Can be confirmed. At this time, the image line C constituting the visible image does not coincide with the center line 7 of each lens of the lenticular lens, and is not viewed from directly above the first discriminating tool 2. As a result, the visible image of the printed pattern 3 shown in FIG. 2 is switched to the first invisible image 5 as shown in FIG. Further, the center line 7 of each lens of the first discriminating tool 2 moves so as to coincide with the line L2 in FIG. 4 so that the image line A1 ′ and the image line A2 ′ are enlarged. In this case, the first invisible image visually recognized by the image line A1 ′ and the image line A2 ′ is visually recognized with negative / positive reversal.

The printed pattern 3 shown in FIG. 12A is a combination of the visible image shown in FIG. 9A and the invisible image shown in FIG. 9B. As a second authenticity determination method, for example, an image input / display device or the like equipped with a camera (or an optical scanner) that performs infrared viewing is used as the second determination tool 4 as shown in FIG. When viewed with infrared rays, the second invisible image as shown in FIG. 12B is expressed as a visible image. That is, when viewed with infrared rays, the image line C, image line A2, image line A2 ′, image line E2 and image line a2 which do not contain an infrared absorbing dye are only surface reflection light on the substrate of the printed matter 1, Only the image line A1, the image line A1 ′, the image line E1, and the image line a1 containing the absorbing dye are confirmed, and the second invisible image is observed as a visible image. That is, in the infrared vision, the image line including the infrared absorbing dye and the image line not including the infrared absorptive dye are in an on-off relationship with each other. The image line A1, the image line A1 ′, the image line E1 and the image line a1 made of a color material containing an infrared absorbing dye are black (on), and the image line C made of a color material containing no infrared absorbing dye, The image line A2, the image line A2 ′, the image line E2, and the image line a2 are recognized as white (off), and basically, both of them are not black or both of them are white. Thus, the forgery prevention printed matter is provided with a different first authenticity determination method and second authenticity determination method. As the number of units arranged in a matrix increases, the resolution of the image becomes higher, and the second invisible image 6 as shown in FIG. 3B can be expressed.

Further, the unit configuration may be an image line configuration shown in FIG. FIG. 4B shows an image line E1 and / or an image line E2 and an image line a1 and / or an image line a2 for alleviating that the concentration shown in FIG. Are arranged so as to be sandwiched between the image line C regions. That is, the image line a1 and / or the image line a2 and the image line E1 and / or the image line E2 shown in FIG. 4B are the image line A1 and / or the image line A2 and the image line A1 ′ and In other words, they are arranged with a length of 1/3 of the dimension Sh in the lateral direction of the unit with respect to the image line A2 ′. The image line a1 and / or the image line a2 is an image area that is half of the image line A1 and / or the image line A2, and is arranged in the unit vertical direction with respect to the image line A1 and / or the image line A2, and is a matrix. Are arranged so as to be sandwiched between the image line A1 ′ and / or the image line A2 ′ and the image line A1 ′ and / or the image line A2 ′ in the vicinity of the unit arranged in a shape. On the other hand, the image line E1 and / or the image line E2 and the image line E1 and / or the image line E2 have an image area that is half of the image line A and / or the image line A ′, and the image lines A1 ′ and / or Alternatively, it is arranged in the vertical direction of the unit with respect to the image line A2 ′, and in the vicinity of the unit arranged in a matrix, the image line A1 and / or the image line A2 and the image line A1 and / or the image line A2 It is arranged to be sandwiched. Thus, the image lines for reducing the density imbalance of the image lines for the first invisible image are connected in a horizontal straight line in the unit horizontal direction. The same effect can be achieved in the image line configuration of the unit shown in FIG.
