Description

  The present invention provides banknotes, stock certificates, securities such as receivables, various certificates and valuable documents, printed matter that needs to be prevented from forgery or duplication, printed matter utilized for artistic appreciation, The present invention relates to a manufacturing method and a manufacturing system.

  In general, a variety of technologies are applied to valuable printed matter such as certificates in order to provide an anti-counterfeiting effect. However, in recent years, with the increase in image quality of color copiers and computerization of color platemaking technologies, The forgery technology tends to diversify. As a method for preventing these counterfeiting, there are many anti-counterfeiting techniques using special materials, which are not usually observed under light, but are provided with an invisible image observed under specific conditions.

  Anti-counterfeiting technology using these special materials is visible as a uniform color under visible light, but is printed using infrared transmission / absorption pair inks that are observed in different colors under infrared light. A typical example is a printed material using a light-emitting material that is transparent and develops color when irradiated with energy rays such as ultraviolet rays, thereby causing an invisible image to appear.

  The technology using printed materials and luminescent materials using infrared transmission and absorption pair inks requires special materials and introduces special equipment consisting of special machinery and equipment to obtain an environment for confirming anti-counterfeiting effects. For example, the authenticity determination means is expensive.

  Therefore, the present applicant regularly forms a plurality of units that can form equal colors and lines of the same area, which are formed using general color materials, without using special materials. In each unit, the image line is arranged in one of a pair of image lines arranged so as to oppose the center to the boundary. An application has been filed for a printed matter in which an invisible image appears as a visible image when observed in a superimposed manner (for example, see Patent Document 1).

  The printed matter of Patent Document 1 can arrange an image line that forms a visible image and an image line that forms a second invisible image in each regularly formed unit. A visible image is observed when observed below, and a first invisible image is observed when the discriminator is overlapped along the first direction, and the discriminator is overlapped along a second direction different from the first direction. The printed matter has an image switching effect such that the second invisible image can be observed when observed.

  In addition, as in the invention of Patent Document 1, the applicant of the present invention forms a plurality of units having a line area for forming a visible image and an image area for forming at least one invisible image. Filed an anti-counterfeit printed matter that has the same effect as document 1 and has a visible image having a continuous tone that reproduces shadows from highlights by means of halftone image lines. (For example, refer to Patent Document 2).

  The printed matter of Patent Document 2 arranges an image line that forms a visible image based on image data having continuous gradation such as a face photograph, and further arranges an image line that forms at least one invisible image in each unit. By doing so, an invisible image can be formed in the region where the face photograph is formed.

  Further, as a printed matter in which a continuous tone is added to an invisible image that is visualized when the discriminating tool is overlaid, each line element is formed by partially changing the phase shift amount according to the density of the invisible image. Thus, a printed matter on which an invisible image having at least one continuous tone is formed is disclosed (for example, see Patent Document 3).

  However, in the printed matter of Patent Document 1 and Patent Document 2, a pair of image lines that form an invisible image is formed with image lines of the same color and the same area, and in each unit, either one of the image lines is formed. Since the invisible image is formed by forming the image line by the negative / positive relationship of selecting and arranging, the density of the image line forming the pair of invisible images cannot be partially changed.

Then, when the discriminating tool 2 is superimposed on the printed matter 1 with a predetermined angle, a first invisible image 5 as shown in FIG. 3 appears.

(First embodiment)
Below, the printed matter 1 in the 1st Embodiment of this invention is demonstrated. FIG. 4 shows a minimum unit element configuration (hereinafter referred to as “unit”) constituting the printed matter 1 in the first embodiment, and each unit includes an image portion of the first invisible image 5. , A second element A ′ that forms the background of the first invisible image 5, and a third element C that forms the visible image 4.

  The vertical and horizontal dimensions S of the unit are the same, for example, 340 μm, and the size is 1 mm or less. Arbitrary visible image 4 and first invisible image 5 are formed by arranging these minimum unit units in a matrix. In addition, although the printed matter 1 in 1st Embodiment used the coated paper as the base material and formed the printing pattern 3 which made the dimension S of the unit 340 micrometers by inkjet printing, the dimension S of the unit, the base material, the printing method, The printing material and the printing apparatus are not limited at all.

  The first element A that forms the image portion of the first invisible image 5 and the second element A ′ that forms the background portion of the first invisible image 5 are in a pair relationship, and in all units, the first element A ′ An element portion of the first invisible image 5 is formed by the element A, and a background portion is formed by negatively inverting the first invisible image 5 by the second element A ′. Thereby, since the color which totaled the 1st element A and 2nd element A 'in each unit is observed as a uniform color, when observing the printing pattern 3, the 1st element A and the 2nd element The element A ′ is observed as a flat state having a constant density (for example, a gray background), and only the visible image 4 formed by the third element C as shown in FIG. 2 is observed. The method for forming the first element A and the second element A ′ will be described in detail later.

  As described above, the present invention needs to be formed so that the total color of the first element A and the second element A ′ in each unit is visually recognized as the same color in all the units. However, it is not necessary to form the colors of the first element A and the second element A ′ arranged in all the units as the same color, and the first element formed in each unit as shown in FIG. Arbitrary colors can be arranged by forming the second element A ′ according to the element A.

  Further, FIG. 6 shows a state in which the discriminating tool 2 is superposed on the printed matter 1 in order to visually recognize the first invisible image 5. As for the positional relationship between the printed material 1 and the discriminating tool 2 when the discriminating tool 2 is observed on the printed material 1, the center line 7 of the discriminating tool 2 (line pattern) (In the case of a filter having a center, the center of a non-element part, and in the case of a lenticular lens, the center of a convex part constituting the lens) are observed by overlapping the discriminator 2 so as to coincide with the line L1 in each unit Thus, only the first element A that forms the image portion of the first invisible image 5 is enlarged, and the second element A ′ and the third element C that do not exist on the center line 7 of the discriminator 2 are not observed. Since it becomes a state, the visible image 4 disappears and the first invisible image 5 appears.

  Further, if the third element C is formed at a position that is not emphasized by the discriminator 2 when observing the first invisible image 5, that is, a position shifted from the line L1 in each unit, the size and Since a color or the like can be arbitrarily set, it can be formed as a visible image 4 having continuous gradation such as a photographic image. The visible image 4 referred to in the present invention is an image visually recognized when the printed matter 1 is visually observed under a normal light source, and the invisible image is visually recognized when visually observed under a normal light source. An image that is not or hardly visible.

  FIG. 7 shows a state in which a plurality of units having such a configuration are continuously and regularly arranged on the printed matter 1 in a matrix without any gaps. FIG. 7A shows the relationship between the printed material 1 on which a plurality of units are formed and the discriminating tool 2, and is superimposed so that the center line 7 of the discriminating tool 2 coincides with the line L1 in each unit. The observed state is shown. The elements observed in this case are only the first element A forming the image portion of the first invisible image 5 where the center line 7 of the lenticular lens as the discriminator 2 overlaps. As shown in FIG. 7B, only the first element A is enlarged and observed, so that the first invisible image 5 shown in FIG. 3 appears. At this time, the second element A ′ forming the background portion of the first invisible image 5 and the third element C forming the visible image 4 are shifted from the center line 7 of the lenticular lens. Because it is formed, it is not observed.

  Further, as for the units constituting the printed matter 1 of the first embodiment, the unit shown in FIG. 8A has been described as an example, but the first element A is arranged on the line L1 in each unit, The configuration is not limited to this as long as the second element A ′ and the third element C are not arranged on the line L1. For example, as shown in FIG. 8B, the first element A, the second element A ′, and the third element C fill the entire unit, or the first element as shown in FIG. 8C. A is arranged in the central part of the unit, the second element A ′ is arranged as a quarter of the circle so that the center of the circle comes to the corner of the unit, and the third element C is As shown in FIG. 8D, the first element A, the second element A ′, and the third element C are divided in the horizontal direction of the unit. Various arrangements, such as a configuration to be arranged as described above, are possible, and any arrangement may be used as long as the effects of the present invention can be obtained.

  Next, an example of an apparatus used for producing the printed matter 1 according to the first embodiment will be described with reference to FIG. This manufacturing apparatus includes an input unit 401, a processing unit 402, a storage unit 403, and an output unit 404. The input unit 401 inputs data necessary for producing the printed material 1 according to the first embodiment and supplies the data to the processing unit 402. The processing unit 402 stores the given data in the storage unit 403, performs arithmetic processing and image processing necessary for producing the printed material 1, and gives the obtained result to the output unit 404.

The negative image is cut out by the second element A ′ in the unit.

  Next, as f5, a process of combining the target image (positive image) cut out in the step f3 and the negative image of the target image cut out in the step f4 in each unit is performed. At this time, since the total color and density of the first element A and the second element A ′ formed in each unit need to be kept constant in the printed pattern 3, each unit is given by f6. The RGB value obtained by summing the formed first element and the second element A ′ is calculated, and the color obtained by summing the first element A and the second element A ′ is observed as the same color in all units. The process which determines whether or not is performed.

  At this time, when it is determined that the total color of the first element A and the second element A ′ in each unit is the same color, the process proceeds to f11, and the element forming the first invisible image 5 is displayed. The production is finished. On the other hand, when it is determined that the colors of the first element A and the second element A ′ are not the same color, the process proceeds to f7, and the process of correcting the color of the second element A ′ in each unit is performed. Do.

  At f7, the second element A ′ hollowed out at f4 is erased, and at f8, the total RGB value of the first element A formed in each unit (hereinafter referred to as “A total”). And the maximum RGB value that can be formed in the area of the first element A according to the following formula, in f9, to calculate the RGB value of the second element A ′ arranged in each unit: A value obtained by subtracting “Total” from the total value of the values (each 255) and dividing the value by the area of the second element A ′ is the density of the element formed in each second element A ′.

  Since the RGB value of the second element A ′ arranged in each unit is determined by the above equation 1, the second element A ′ arranged in all the units is arranged at f10. Thereby, it can be set as the state observed as a uniform color the color which totaled the 1st element A and 2nd element A 'in all the units.

  Since the first element A and the second element A ′ forming the first invisible image 5 can be observed as the same color by the process up to f6 or the processes from f7 to f10, f11 By the processing of the first element A and the second element that form the first invisible image 5 by inputting the target image of the visible image 4 and hollowing out the third element C formed in each unit. The element A ′ and the third element C forming the visible image 4 can be synthesized.

  According to the above manufacturing method, by using the printed material manufacturing system using the manufacturing apparatus in FIG. 9, an invisible image having a photographic gradation can be provided as a valuable printed material such as various certificates by on-demand printing.

(Second Embodiment)
A printed material 1 according to a second embodiment of the present invention will be described with reference to the drawings. The printed material 1 in the second embodiment is different from the printed material 1 in the first embodiment, and the first invisible image 5 is observed when the discriminator 2 is superimposed on the printed material 1 at a predetermined angle. Furthermore, a second invisible image 6 different from the first invisible image 5 is observed when the discriminator 2 is overlapped at an angle different from the predetermined angle.

  FIG. 11 shows a unit of the minimum unit constituting the printed matter 1 in the second embodiment, and each unit includes a first element A (forming an image portion of the first invisible image 5). a), a second element A ′ (b) that forms the background portion of the first invisible image 5, a fourth element B (c) that forms the image portion of the second invisible image 6, The second element B ′ (d) forming the background portion of the second invisible image 6 and the third element C forming the visible image 4 are included.

  The vertical and horizontal dimensions S of the unit are the same, for example, 340 μm, and the size is 1 mm or less. Arbitrary visible image 4, first invisible image 5 and second invisible image 6 are formed by arranging these minimum unit units in a matrix. In addition, although the printed matter 1 in 2nd Embodiment used the coated paper as the base material and formed the printing pattern 3 which made the dimension S of the unit 340 micrometers by inkjet printing, the dimension S of a unit, a base material, the printing method, The printing material and the printing apparatus are not limited at all.

  The first element A that forms the image portion of the first invisible image 5 and the second element A ′ that forms the background portion of the first invisible image 5 are in a pair relationship, and in all units, the first element A ′ An element portion of the first invisible image 5 is formed by the element A, and a background portion is formed by negatively inverting the first invisible image 5 by the second element A ′. Further, the fourth element B that forms the image portion of the second invisible image 6 and the fifth element B ′ that forms the background portion of the second invisible image 6 are in a pair relationship, and in all units, An image portion of the second invisible image 6 is formed by the fourth element B, and a background portion is formed by negatively inverting the second invisible image 6 by the fifth element B ′. Thereby, in each unit, the total color of the first element A and the second element A ′ is observed as a uniform color, and further, the total color of the fourth element B and the fifth element B ′ is equal. Since it is observed as a color, when the printed pattern 3 is observed, the total color of the first element A, the second element A ′, the fourth element B, and the fifth element B ′ is a constant density. As shown in FIG. 2, only the visible image 4 formed by the third element C as shown in FIG. 2 is observed.

  On the other hand, when the discriminating tool is overlapped and observed along the predetermined angle on the printed matter 1, the first invisible image 5 shown in FIG. 12A is observed, and the discriminating tool 2 is moved in a direction different from the predetermined angle described above. When observed while being overlapped, the second invisible image 6 shown in FIG. 12B is observed.

  As described above, the total color of the first element A and the second element A ′ and the total color of the fourth element B and the fifth element B ′ in each unit are the same color in all units. It is necessary to form so as to be visually recognized. However, it is necessary to form the color of the first element A and the color of the second element A ′, the color of the fourth element B, and the color of the fifth element B ′ arranged in all units as the same color. Instead, as shown in FIG. 13, the second element A ′ having a gradation obtained by inverting the gradation of the first element A formed in each unit and the gradation possessed by the fourth element B are inverted. Arbitrary colors (elements) can be arranged in a state in which the first invisible image 5 and the second invisible image 6 are invisible by forming the fifth element B ′ having the gradation that has been adjusted.

  Further, FIG. 14 shows a state in which the discriminator 2 is overlapped on the printed matter 1 along a predetermined angle in order to visually recognize the first invisible image 5. As for the positional relationship between the printed material 1 and the discriminating tool 2 when observing the discriminating tool 2 on the printed material 1, the predetermined angle when observing the first invisible image 5 is that of the unit shown in FIG. The first invisible image is obtained by superimposing the discriminator 2 so that the center line 7 coincides with the line L1 in each unit at the position where the center line 7 of the discriminator 2 is aligned with the position of the line L1. Only the first element A that forms the image portion 5 is enlarged, and the second element A ′, the third element C, the fourth element B, and the fifth element B that are not on the center line 7 of the discriminator 2 are enlarged. Since 'is not observed, the visible image 4 disappears and the first invisible image 5 appears. Further, the predetermined angle when observing the second invisible image 6 is a position obtained by aligning the center line 7 of the discriminator 2 with the position of the line L3 of the unit shown in FIG. 11, and the line L3 in each unit. By observing the discriminating tool 2 so that the center lines 7 coincide with each other, only the fourth element B forming the image portion of the second invisible image 6 is enlarged, and is not on the center line 7 of the discriminating tool 2. Since the first element A, the second element A ′, the third element C, and the fifth element B ′ are not observed, the visible image 4 disappears and the second invisible image 6 appears. .

  The third element C is located at a position not corresponding to the center line 7 of the discriminator when observing the first invisible image 5 and the second invisible image 6, that is, from the line L1 and the line L3 in each unit. If it is formed at a shifted position, the size, color and the like can be arbitrarily set, so that it can be formed as a visible image 4 having a continuous tone such as a photographic image.

  FIGS. 15 and 16 show a state in which a plurality of units having such a configuration are continuously and regularly arranged on the printed matter 1 in a matrix without any gaps. FIG. 15A shows the relationship between the printed material 1 on which a plurality of units are formed and the discriminator 2, and is superimposed so that the center line 7 of the discriminator 2 coincides with the line L 1 in each unit. The observed state is shown. The element observed in this case is the first element A forming the image portion of the first invisible image 5 where the center line 7 of the lenticular lens overlaps, and is shown in FIG. Thus, only the 1st element A is expanded and observed, and the 1st invisible image 5 shown in Drawing 12 (a) is observed. At this time, the second element A ′ forming the background portion of the first invisible image 5, the fourth element B and the fifth element B ′ forming the second invisible image 6, Since the third element C forming the visible image 4 is formed at a position shifted from the center line 7 of the lenticular lens, it is not observed.

  Further, FIG. 16 shows a state observed in such a manner that the center line 7 of the discriminator 2 coincides with the line L3 in each unit. The element observed in this case is the fourth element B forming the image portion of the second invisible image 6 where the center line 7 of the lenticular lens overlaps, and is shown in FIG. Thus, the second invisible image 6 shown in FIG. 12B is observed by magnifying and observing only the fourth element B. At this time, the fifth element B ′ forming the background portion of the second invisible image 6, the first element A and the second element A ′ forming the first invisible image 5, Since the third element C forming the visible image 4 is formed at a position shifted from the center line 7 of the lenticular lens, it is not observed.

  Further, as for the units constituting the printed matter 1 of the second embodiment, the unit shown in FIG. 11 has been described as an example, but only the first element A is arranged on the line L1 in each unit, and each unit If it is the structure which arrange | positions only the 4th element B on the line L3 in a unit, it will not be limited to this. For example, as shown in FIG. 17A, the first element A, the second element A ′, the third element C, the fourth element B, and the fifth element B ′ can be used to fill the entire unit. As shown in FIG. 17B, the first element A is arranged on the line L1 excluding the central portion of the unit, the second element A ′ is divided into the upper and lower parts of the unit, and the fourth element is arranged. B is arranged on the line L3 excluding the central portion of the unit, the fifth element is arranged by being divided into the left and right ends of the unit, and the third element C is arranged in the first element A excluding the center of the unit. The second element A ′, the fourth element B, and the fifth element B ′ may be formed in a region where the element is not disposed.

  Next, the manufacturing process of the printed matter 1 in the second embodiment will be described with reference to the flowchart of FIG. First, as f12, a target image serving as a basis for the first invisible image 5 and the second invisible image 6 is prepared. As the target image at this time, a method of taking a face photograph or the like to obtain a target image, image information input in advance, or the like can be used.

  Next, each of the target images of the first invisible image 5 and the second invisible image 6 input in f12 is duplicated, and a negative image is produced by inverting the input image. The negative image of the first invisible image 5 produced here is an image formed on the second element A ′, and the negative image of the second invisible image 6 is an image forming the fifth element B ′. is there. Next, as a process after f14, the first element A and the second element A ′ that form the first invisible image 5 are produced. In f14, the target image (positive image) is cut out by the first element A in each unit arranged in a matrix in accordance with the number of lines of the discriminator 2, and in f15, a plurality of arrangements arranged in a matrix are performed. The target image (negative image) is cut out by the second element A ′ in the unit.

  Next, in f16, a process of forming the target image (positive image) hollowed out in the step f14 and the target image (negative image) hollowed out in the step f15 in each unit is performed. At this time, since the total color of the first element A and the second element A ′ formed in each unit needs to be in a constant state in the printed pattern 3, it is formed in each unit by f17. RGB values obtained by summing the first element and the second element A ′ are calculated, and whether or not the color obtained by summing the first element A and the second element A ′ is observed as a uniform color in all units. The process which determines is performed.

  At this time, when it is determined that the total color of the first element A and the second element A ′ in each unit is the same color, the process proceeds to f22 and the fourth invisible image 6 is formed. The process proceeds to the step of forming the element B and the fifth element B ′. On the other hand, when it is determined that the colors of the first element A and the second element A ′ are not the same color, the process proceeds to f18 and the process of correcting the color of the second element A ′ in each unit is performed. Do.

  In f18, the second element A ′ formed in f16 is erased, and in f19, the total RGB value of the first element A formed in each unit (hereinafter referred to as “A total”). And the maximum RGB value that can be formed in the area of the first element A according to the following equation, at f20, to calculate the RGB value of the second element A ′ arranged in each unit: A value obtained by subtracting “Total” from the total value of the values (each 255) and dividing the value by the area of the second element A ′ is the density of the element formed in each second element A ′.

  Since the RGB value of the second element A ′ arranged in each unit is determined by the above equation 2, the second element A ′ arranged in all the units is formed in f21. Thereby, it can be set as the state observed as a uniform color the color which totaled the 1st element A and 2nd element A 'in all the units.

  Through the processes up to f17 or the processes from f18 to f21, all the steps of arranging the first element A and the second element A ′ that form the first invisible image 5 are finished, and the second process after f22 is completed. The process proceeds to the process of forming the invisible image 6 and the visible image 4.

  In f22, a target image (positive image) is cut out by the fourth element B in each unit arranged in a matrix according to the number of lines of the discriminator 2, and in f23, a plurality of elements arranged in a matrix are processed. The target image (negative image) is cut out by the fifth element B ′ in the unit.

  Next, in f24, a process of forming the target image (positive image) cut out in the step f22 and the target image (negative image) cut out in the step f23 in each unit is performed. At this time, since the total color of the fourth element B and the fifth element B ′ formed in each unit needs to be in a constant state in the printed pattern 3, it is formed in each unit by f25. In addition, the RGB value obtained by summing the fourth element B and the fifth element B ′ is calculated, and the color obtained by summing the fourth element B and the fifth element B ′ is observed as the same color in all units. Processing to determine whether or not.

  At this time, when it is determined that the total color of the fourth element B and the fifth element B ′ in each unit is the same color, the process proceeds to f30 and the fourth invisible image 6 is formed. The manufacturing process of the element B and the fifth element B ′ is completed. On the other hand, when it is determined that the colors of the fourth element B and the fifth element B ′ are not the same color, the process proceeds to f26, and the process of correcting the color of the fifth element B ′ in each unit is performed. Do.

  In f26, the fifth element B ′ formed in f24 is erased. In f27, the total RGB value of the fourth element B formed in each unit (hereinafter referred to as “B total”). And calculate the RGB value of the fifth element B ′ arranged in each unit at f28, so that the maximum RGB that can be formed in the area of the fourth element B by the following equation: A value obtained by subtracting “Total” from the total value (each 255) and dividing the value by the area of the fifth element B ′ is the density of the element formed in each fifth element B ′.

  Since the RGB value of the fifth element B ′ arranged in each unit is determined by the above Equation 3, the fifth element B ′ arranged in all the units is formed at f29. Thereby, it can be set as the state which observes as a color the color which totaled the 4th element B and 5th element B 'in all the units.

  Through the above steps, the first element A and the second element A ′ that form the first invisible image 5, and the fourth element B and the fifth element B ′ that form the second invisible image 6 Since the density of all the units can be kept constant, the image to be the target of the visible image 4 is input by the processing of f30, and the first element is cut out by the third element C formed in each unit. The respective elements forming the invisible image 5 and the second invisible image 6 and the third element C forming the visible image 4 can be combined.

  In the second embodiment, the fourth element B that forms the image portion of the second invisible image 6 with reference to the direction in which the first element A that forms the image portion of the first invisible image 5 is arranged. In the example in which two invisible images are formed by forming them along the orthogonal direction, the direction in which the center line 7 of the discriminator overlaps, that is, the direction in which the image portion of the invisible image is formed is three or more directions. By doing so, it is also possible to form three or more invisible images.

  According to the above manufacturing method, by using the printed material manufacturing system using the manufacturing apparatus in FIG. 9, an invisible image having a photographic gradation can be provided as a valuable printed material such as various certificates by on-demand printing. First, an input unit 401 for inputting a base image of the visible image 4, the first invisible image 5 and the second invisible image 6 by a digital camera or a scanner, the input image, the first element A, and the second element Arrangement of units having A ′, third element C, fourth element B, and fifth element B ′, a storage unit 403 that stores image data input by the input unit 401, and a first invisible image 5 and second invisible image 6 negative image creation, visible image 4, first invisible image 5 positive image and negative image, second invisible image 6 positive image and negative image as elements in each unit. A processing unit 402 that performs cutout processing and performs processing such as color correction of the second element B ′ and / or the fifth element B ′, and an output unit that prints the printed pattern 3 by an output device such as an inkjet printer or a laser printer Equipped with 404 Was With printed material preparation system, it is possible to obtain the printed matter 1 easily in the second embodiment.

(Third embodiment)
A printed matter 1 in the third embodiment will be described with reference to the drawings. The printed matter 1 in the third embodiment is different from the example in which a full-color photographic gradation image is formed on an invisible image as in the first embodiment and the second embodiment. This is a form for fixed printing in which a continuous tone image is formed by changing the density (element area ratio) stepwise. FIG. 19 shows a unit of the minimum unit constituting the printed matter 1 in the third embodiment, and each unit includes a first element A that forms an image portion of the first invisible image 5 and The second element A ′ forming the background portion of the first invisible image 5 and the third element C forming the visible image 4 are included.

  The vertical and horizontal dimensions S of the unit are the same, for example, 340 μm, and the size is 1 mm or less. Arbitrary visible image 4 and first invisible image 5 are formed by arranging these minimum unit units in a matrix. Note that the printed matter 1 in the third embodiment has a printed pattern 3 in which fine paper is used as a base material and the unit size S is 340 μm by offset printing, but the unit size S, the base material, the printing method, The printing material and the printing apparatus are not limited at all.

  The first element A that forms the image portion of the first invisible image 5 and the second element A ′ that forms the background portion of the first invisible image 5 are in a pair, and a plurality of them are regularly formed. In each unit, since the total density of the first element A and the second element A ′ needs to be kept constant, as shown in FIG. 20, the first element A is a light color (a) When the second element A ′ is reproduced with a dark color and the first element A is reproduced with a dark color (d), the second element A ′ is reproduced with a light color. Thereby, since the color which totaled the 1st element A and 2nd element A 'in each unit can be made into a uniform color, when observing the printing pattern 3, it is 1st element A and 2nd The element A ′ is observed as a flat state having a constant concentration. In addition, since the printed matter 1 in the third embodiment is formed by fixed printing, it is necessary to form the first element A and the second element A ′ with the same color material. As a result, if the total element area of the first element A and the second element A ′ formed in each unit is formed as an equal combination in all units, the concentration of all units can be kept constant. In addition, the first invisible image 5 can be made a gradation image by arbitrarily setting the area of the first element A.

  FIG. 21 shows a state in which the discriminator 2 is superposed on the printed matter 1 to observe the first invisible image 5. As for the positional relationship between the printed material 1 and the discriminating tool 2 when the discriminating tool 2 is observed on the printed material 1, the center line 7 of the discriminating tool 2 matches the position of the line L1 in the unit shown in FIG. , Only the first element A that forms the image portion of the first invisible image 5 is enlarged, and the second element A ′ and the third element that are not on the center line 7 of the determination tool 2 are enlarged. Since the element C is not observed, the visible image 4 disappears and the first invisible image 5 appears.

  Further, if the third element C is formed at a position that is not observed when observing the first invisible image 5, that is, a position that is shifted from the position of the line L1 in each unit, the size, the color, and the like are changed. Since it can be set arbitrarily, it can be formed as a visible image 4 having continuous gradation such as a photographic image.

  FIG. 22 shows a state in which a plurality of units having such a configuration are arranged continuously and regularly on the printed matter 1 in a matrix without any gaps.
