Description

  The present invention relates to a transmission latent image pattern formed body in which a latent image is applied to banknotes, passports, securities, gift certificates, and various certificates for the purpose of preventing forgery and duplication.

  Various anti-counterfeiting technologies are applied to valuable printed matter such as banknotes, passports, securities, gift certificates and various certificates in order to prevent forgery, alteration and copying. Among them, a variety of techniques for forming a latent image are proposed. For example, a line is formed using a printing method that can form a convex image line on the substrate, such as intaglio printing, gravure printing, or screen printing, and a background line and a latent image part are formed. There is a technique in which a latent image pattern appears by tilting a base material with different line arrangement directions.

  In addition, the printed matter alone can be seen as a simple line pattern or lattice pattern, but there is a technique of a hidden pattern in which a latent image pattern appears when a discriminator having a predetermined rule is superimposed.

  Furthermore, a printed pattern is formed on the front and back of the base material, and there is no meaningful information (pattern) on one side of each other, but when the base material is viewed through light, the patterns on the front and back are combined and meaningful. There is a synthetic pattern that can be confirmed as information.

  With respect to this front and back synthetic pattern, the applicant prints a line pattern in three colors of cyan, magenta and yellow on one surface of a base material that transmits light, and the base material is in the same position as the line pattern. By printing a part of the three lines of cyan, magenta, and yellow slightly shifted in the vertical direction with respect to the lines on the other side of the print, Different from the other portions, the density of the intersection of the parallel lines and the lines formed by shifting to the other surface is different from that of the other parts, and a front and back pattern composite printed matter that can be confirmed by forming a desired pattern is disclosed. (For example, refer to Patent Document 1).

  Further, the medium is formed in a state where the lines of the same shape are aligned in a partial area or the entire area of the front and back surfaces of the transparent center base material sheet, and is formed on either of the front and back surfaces. A line is composed of a latent image portion and a non-latent image portion, and a line formed on the other surface is composed of a non-latent image portion and a latent image portion, and all the lines are formed in parallel. The lines forming the latent image portion are composed of lines that are shifted by 1/2 pitch with respect to the lines forming the latent image portion, and the latent image portions on the front and back surfaces are arranged so as not to be in the same position on the front and back sides. In order to cover the lines formed on either one of the front and back surfaces, a solid print layer made of a background color that emphasizes the lines and the lines formed on the other surface is applied. A medium having a characteristic image change function is disclosed (for example, see Patent Document 2).

  In the medium of this Patent Document 2, since the lines formed on either one of the front and back surfaces are composed of a latent image portion and a non-latent image portion, they are formed on one surface when viewed from either the front or back side. A line composed of a latent image part and a non-latent image part and a line formed on the other surface were combined, and the latent image part emerged from the non-latent image part by viewing with a different viewing angle. It is visualized like this.

Japanese Patent No. 3362171 Japanese Patent No. 4016707

  However, since the front and back pattern composite printed matter disclosed in Patent Document 1 forms an image desired to appear as a latent image image by using the shades appearing at the intersections of front and back lines on the basis of the original image, For the design of the position where the lines are shifted so that the position corresponds to, etc., advanced technology is required and high registration accuracy of the front and back line patterns is required, so forgery and anti-duplication technology However, there remains a problem that difficulty is required in the manufacturing process.

  Further, the medium having an image changing function disclosed in Patent Document 2 forms a latent image by shifting the pitch of some of the lines on one of the lines printed on the front and back. Therefore, only a relatively monotonous image can be formed, and once the configuration is known, it is easily forged.

  Furthermore, the regularity of the pitch between the latent image portion and the non-latent image portion is important for the medium having the image changing function disclosed in Patent Document 2, and a clear image appears if the front and back sides do not match. Since this is not possible, there is a problem that high registration accuracy is required.

  The present invention is intended to solve such a conventional problem, and an element having a higher transmittance than that of the substrate is provided on one side of the transparent substrate, particularly the paper substrate. Arrange elements in a line using two colors of ink different from the base material on the same side or the other side where the lines are aligned.

  Embodiments for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments to be described below, and includes various other embodiments within the scope of the technical idea described in the claims.

  FIG. 1 is a view showing an example of a transmission latent image pattern formed body (1) (hereinafter referred to as “formed body”) in the present invention. As shown in FIG. 1, the formed body (1) has a latent image pattern region (3) in which the transmission latent image pattern according to the present invention is formed on at least a part of the substrate (2). . As shown in FIG. 1, in areas other than the latent image pattern area (3), necessary information such as fees, characters or other patterns is printed in a known printing method (for example, offset printing or intaglio printing). It may be given by.

  As the base material (2) in the present invention, paper such as high-quality paper, coated paper or art paper, and films or plastics can be used. However, it is preferable to use a base material made of a material having an opacity greater than 90% in order to obtain a contrast when the transmission latent image pattern, which is a feature of the present invention, is viewed under transmitted light. This opacity will be described in detail when the second element formed in the latent image pattern region (3) is described.

  2 and 3 are views showing a state when the latent image pattern region (3) in the formed body (1) is observed under a predetermined condition. Although the details of the formed body (1) in the present invention will be described later, the second element group (14) having a higher transmittance than the base material (2) is formed on one surface of the base material (2). On the second element group (14) or on the opposite side of one surface of the substrate (2) on which the second element group (14) is formed (hereinafter referred to as "the other element group"). The first element group (11) is formed of colored ink on the surface. Fig.2 (a) is the figure which confirmed the state in which the 1st element group (11) and the 2nd element group (14) are formed in one surface of a base material (2) under reflected light. In FIG. 2B, the first element group (11) is formed on the other surface of the substrate (2), and the second element group (14) is formed on one surface of the substrate (2). It is the figure which confirmed the state in which it was formed under reflected light. 2A and 2B, when the latent image pattern region (3) of the formed body (1) is confirmed under reflected light, as shown in FIG. Various reflective patterns (4) can be confirmed.

  Further, as shown in FIGS. 3A and 3B, when the latent image pattern region (3) is confirmed under transmitted light, as shown in FIG. 3C, the transmitted latent image pattern (5) is obtained. Can be confirmed. The transmission latent image pattern (5) is composed of a pattern portion (6) (in FIG. 2 (d), the letter “A”) and a background portion (7) constituting the periphery thereof. Each of these components and the visual recognition principle will be described later. In FIGS. 3A and 3B, predetermined light is irradiated to confirm the transmission latent image pattern (5). However, it is not particularly necessary to use a light source. Then, the formed body (1) may be held over and visually recognized in a watermarked state. In the present invention, the state of confirming these transmission latent image patterns (5) is referred to as confirmation under transmitted light. The observation direction is not limited, and refers to a state in which the formed body (1) is between the observer and the light source.

  Hereinafter, the configuration of the latent image pattern region (3) forming the transmission latent image pattern (5) will be described.

  First, as shown in FIG. 1, the formed body (1) has a latent image pattern region (3) in at least a part on the substrate (2). The latent image pattern region (3) The same part of the front and back sides are collectively referred to as a latent image pattern region (3). In the latent image pattern region (3), elements constituting the transmission latent image pattern (5) of the formed body (1) in the present invention are formed.

  Fig.4 (a) is a figure which shows typically an example of a structure of the 1st element (8) currently formed in the latent image pattern area | region (3) of a base material (2). The first elements (8) are arranged in lines in the latent image pattern area (3). Even when observed under reflected light, it is very difficult to confirm the elements arranged in a line as shown in FIG. 4A. Actually, it is shown in FIG. It is confirmed as a uniform reflection pattern (4). In the present invention, “line-like” means a state in which a plurality of elements are regularly arranged at a predetermined pitch.

  Moreover, FIG.4 (b) is a figure which shows the structure of the 2nd element (9) currently formed in the latent image pattern area | region (3) of a base material (2). The second element (9) is also arranged in a line in the latent image pattern region (3).

  Hereinafter, each element will be described in detail. First, the first element (8) will be described.

(First element)
The first element (8) is formed of two different color inks. In addition, about two-color ink, one ink may be the same color as the color of a base material (2). However, in the reflective pattern (4) that can be visually recognized under the reflected light, in order to make the formed transmission latent image pattern (5) a uniform pattern that is more difficult to visually recognize, It is preferable to use two colors of ink different from the substrate (2). As a method for forming the first element (8) on the substrate (2), known printing methods such as offset printing, intaglio printing, screen printing, gravure printing, and ink jet printing can be used. Hereinafter, in the present embodiment, the two-color ink forming the first element (8) will be described as having a different color from the base material (2).

  In addition, in the plurality of first elements (8) arranged in a line, two adjacent first elements (8) are arranged correspondingly. In the present invention, the two first elements (8) arranged adjacent to each other are referred to as a first element set (10). Further, a plurality of first element sets (10) are arranged to form a first element group (11). Here, it demonstrates in detail using a 1st element set (10).

  In the first element group (11) shown in FIG. 4 (a), one of the plurality of first element sets (10) constituted by two adjacent first elements (8) is used. FIG. 5 is an enlarged view of one element set (10). First, as described above, the first element (8) is formed of two colors of ink different from the color of the substrate (2). Accordingly, the first element (8) is formed by the first color (12) and the second color (13). One of the first color (12) and the second color (13) constitutes the pattern portion (6) of the transmission latent image pattern (5) of the present invention, and the other constitutes the background portion (7). It is. The first color (12) and the second color (13) are different colors.

As described above, one first element (8) is composed of two colors of the first color (12) and the second color (13), and the first element (8) is composed of two colors. one adjacently arranged a first set of elements (10), the first 1a of elements _(8-1) and the first color in the elements of the 1b (8 ₂₎ and (12) a second color ( 13) is a corresponding arrangement. Here, “corresponding arrangement” will be described. Figure as in 5, the elements of the 1a (8- ₁₎ has on both sides a second color (13), but has a first color (12) in the center, the elements of the 1b (8- ₂ ), the both sides first color (12), center has a second color (13), further, in elements of the 1a element _(8-1) and the 1b (8 _2), The boundary between the first color (12) and the second color (13) is at the same position. Thus, in the elements of the 1a adjacent _(8-1) and the element of the 1b (8 _2), the arrangement of the first color (12) a second color (13) is reversed, and, A state having color boundaries at the same position is referred to as “corresponding arrangement”.

Thus, the first set of elements (10) are elements of the 1a adjacent first color and (12) a second color (13) are arranged corresponding _(8-1) and the second 1b It is constituted by a component (8 _2). A plurality of the first element sets (10) are arranged to form a first element group (11).

As described above, in the first element set (10), the first color (12) and the second color (13) are arranged corresponding to each other, and further, the first pitch (P ₁₎ of each element. ) Is 100 to 1000 μm and the element width (W ₁ ) is 50 to 500 μm, the first element set (10) arranged correspondingly has two colors mixed with the naked eye. In this state, the color boundary in one first element (8) cannot be recognized. Therefore, the first element group (11) in which a plurality of first element sets (10) are arranged is a state in which the first color (12) and the second color (13) are mixed under reflected light. It can only be seen as a pattern.

  Here, the shape of the first element (8) will be described. The first element (8) can be formed in various shapes as shown in FIG. For example, FIGS. 6A to 6C are image lines, in particular, FIG. 6A is a straight line, FIG. 6B is a broken line, and FIG. 6C is a wavy line. 6D is a point group that is an aggregate of a plurality of points, FIG. 6E is a pixel group that is an aggregate of a plurality of pixels, and FIG. It is a character group that is a collection of various characters.

  In the present invention, since the first element (8) is arranged in a line, the shape is preferably formed by an image line. In particular, it is preferable to form the straight line shown in FIG. If it is formed by the broken line shown in FIG. 6B, if the distance between the lines is increased in one line, the transmission latent image pattern (5) itself becomes an unclear pattern. Therefore, it is necessary to set appropriately considering the shape and reproducibility of the transmission latent image pattern (5) to be formed.

  Further, as described above, since the first element (8) is arranged in a line, it is formed by the points, pixels, and minute characters shown in FIGS. 6 (d) to 6 (f). It is necessary to arrange each of them on one image line so that they can be visually recognized as an image line with the naked eye.

For example, FIG. 7 shows an example in which the first element (8) is formed by a point group that is an aggregate of a plurality of points. In this respect, the height or diameter h ₁ is the same as the width (W ₁ ) of the first element (8) shown in FIG. 5, and is in the range of 50 to 500 μm.

In addition, the pitch (p ₁ ) of the microelements between the points is set to a range of 50 to 1000 μm so that the interval is visible to the naked eye as one image line.

The minute characters shown in FIG. 6F are not limited to characters, and may be symbols, numbers, figures, marks, or the like. Furthermore, when forming a line-shaped element by a group of dots, pixels, characters, etc., various shapes may be arranged within one element as shown in FIG. In any case, the shape is not limited as long as the conditions of the height or diameter (h ₁ ) and the pitch (p ₁ ) of the microelements described above are satisfied. In the present invention, a point group that is a set of a plurality of points, a pixel group that is a set of a plurality of pixels, and a set of a plurality of minute characters, symbols, numbers, figures, marks, etc. It is called “element group”. Therefore, from FIG. 6D to FIG. 6G, the first element (8) is formed by the microelement group.

  Although it has been explained that a plurality of “small element groups” may be formed in one element, as shown in FIGS. 8A to 8C, a plurality of shapes are formed in one element. You may form by the drawn line. Naturally, it may be formed by a line and a “small element group” within one element.

Furthermore, as shown in FIG. 8 (d), the first set of elements (10), formed elements of the element of the 1a (8 ₁₎ and the 1b (8 ₂₎ at different shape element Alternatively, as shown in FIG. 8E, each first element (8) may be formed in a different shape in the first element group (11). In any case, the first element (8) is formed in any shape of the first element (8) shown in FIG. 6 in each element in one element and in the first element group. Also good.

  Hereinafter, in the present embodiment, an example in which the first element (8) is formed by a straight line will be described.

  The first element group (11) is an important element constituting the transmission latent image pattern (5), and the first color (12) or the second color (13) is the transmission latent image pattern ( 5).

The relationship between the arrangement of the first color (12) and the second color (13) for forming the transmission latent image pattern (5) will be described with reference to FIG. FIG. 9 is a first element (a) constituting the first element set (10) in order to easily explain the transmission latent image pattern (5) formed in the first element group (11). _8-1) and is divided for each element of the 1b (8 ₂₎ is obtained shown in FIG. 9 (b) 9 and (a).

In the present embodiment, the transmission latent image pattern (5) is the letter “A” as described above. Therefore, the first color (12) and the second color (13) are arranged using a plurality of first elements (8) so as to form the letter “A”. FIG. 9A shows an example in which the transmission latent image pattern (5) is formed using the element 1a- ₁ (8-1), and the pattern portion (5) forming “A” is displayed in the first color ( 12), and the background (6) is formed of the second color (13).

The first set of elements (10), in the elements of the 1a adjacent _(8-1) and the element of the 1b (8 _2), a first color (12) a second color (13) so that if the correspondingly arranged among the first set of elements (10), elements of the 1b (8- ₂₎ example of forming transmission latent image pattern (5) with reference to Figure 9 (b) , and the arrangement of the first color in the element (8 ₂₎ of the 1b of case (12) a second color (13) is arranged in the arrangement opposite that shown in FIG. 9 (a) It is in a state. Therefore, the letter “A” is formed with the pattern portion (5) in the second color (13) and the background portion (6) in the first color (12).

  Thus, the transmission latent image pattern (5) formed on the formed body (1) has a negative-positive relationship as shown in FIGS. 9 (c) and 9 (d) by the first element set (10). The pattern is formed. In FIG. 9C and FIG. 9D, which is not a negative state and which is a positive state, the expression “negative / positive relationship” is used only for easy understanding of the relationship. In essence, one of the first color (12) is the pattern portion (6) and the second color (13) is the background portion, and the other is the first color (12) is the background portion (7). The second color (12) is the pattern portion (6). In addition, the state in which the transmission latent image pattern (5) in the negative / positive relationship can be confirmed depends on the arrangement relationship with the second element (9) described later. The principle will be described later.

Furthermore, for the first set of elements (10), in the elements of the 1a adjacent _(8-1) and the element of the 1b (8 _2), a first color (12) a second color (13 ) Are arranged corresponding to each other, but it is not necessary to arrange them corresponding to each of the first element sets (10). As described with reference to FIG. 9, in the first element group (11), the first color (12) and the second color (13) need to be arranged so as to have a negative-positive relationship. . Accordingly, in all of the plurality of first element sets (10), the arrangement for forming the negative transmission latent image pattern (5) and the positive transmission latent image pattern (5) are formed. The arrangement for it must be arranged regularly. This regular arrangement will be described below.

Figure 10 is a first element group are exemplified in this embodiment shown in FIG. 4 with respect to (11), the arrangement of the plurality of first element set _(10-1 to _10-6) It is a figure for demonstrating. One of the first set of elements (10), as described above, in the elements (8 ₂₎ of the first set of elements of the 1a constituting the (10) elements _(8-1) and the 1b, The first color (12) and the second color (13) are arranged correspondingly. Furthermore, one of the elements 1a-th of the first set of elements (10 ₁ to _{10-6) (8-1)} is, for example, to form a negative state of the transmitted latent image pattern (5), the other first Since the element _1-2 (8-2) forms a positive state, as shown in FIG. 10A, the element 1 a (1 a) for forming a negative transmission latent image pattern (5) _8-1) and the arrangement of the second 1b to form a transparent latent image pattern of the positive state (5) element (8 _2), so that all are alternately arranged.

10A, in order to explain the negative / positive state of the transmission latent image pattern (5) formed by using the first element group (11), each first element set is described. _(10-1 to _10-6) in a diagram element of the 1a (8- ₁₎ and elements of the 1b (8- ₂₎ has easily understand how are arranged in any positional relationship. Thus, for each first set of elements (10 ₁ to _10-6), as shown in FIG. 9 (c), the the arrangement for the first color (12) constituting the pattern portion (6) and going on elements of the 1a (8- _1), as shown in FIG. 9 (d), the element of the 1b second color (13) is in the arrangement for configuring a pattern portion (6) (8 ₂₎ and is shown with a step.

As shown in FIG. 10 (a), elements of the 1a element _(8-1) and the 1b disposed in correspondence (8 _2), the pattern portion by a first color (12) ( the elements of the 1a to form a 6) _(8-1), the elements of the 1b forming the pattern portion (6) by a second color (13) (8 _2), all of which are arranged alternately I understand that. This shows that the steps shown in FIG. 10 (a) are arranged regularly because every other element exists. Therefore, in the present invention, the first set of elements (10), the first 1a element _(8-1) and of the 1b element (8 ₂₎ and being disposed so as to correspond, even more in the first set of elements (10), first 1a an element _(8-1) of the pattern portion by the second color (13) forming the pattern portion (6) by a first color (12) (6) elements of the 1b forming the _(8-2) are preferably all arranged alternately.

For example, as shown in FIG. 10 (b), in each of the first set of elements (10 ₁ to _10-6), elements of the 1a element _(8-1) and the 1b (8 ₂₎ is although it is disposed corresponding elements of the first 1a of elements _(8-1) and the 1b (8 ₂₎ are not all been arranged alternately. It can be seen that the steps shown in FIG. 10B for explanation are different from the steps in FIG. 10A and are present at random, so that the arrangement is not regularly uniform. If arranged in such a positional relationship, an appropriate transmission latent image pattern (5) cannot be formed due to a relationship with a second element (9) described later.

As described above, in the present invention, the first set of elements (10) are not only the elements of the element of the 1a (8- ₁₎ and the 1b (8- ₂₎ is in the arrangement corresponding, first when viewed as a first element group (11), elements of the element of the 1a (8- ₁₎ and the 1b (8- ₂₎ are preferably all are arranged alternately. Such a relationship is called regular arrangement.

  Next, the second element (9) will be described.

(Second element)
The second element (9) has two formation methods with respect to the first element (8) described above. One is formed on the surface of the substrate (2) opposite to the side on which the first element (8) is formed, and the other is formed on the first element (8). It is formed on the same surface as the existing side. In the present invention, as described above, the surface of the substrate (2) on which the second element (9) is formed is one surface, and the substrate (2) on which the second element (9) is not formed. The first element (8) may be formed on either one surface or the other surface in the latent image pattern region (3) of the substrate (2). It becomes. Note that the latent image pattern region (3) on one surface of the substrate (2) and the latent image pattern region (3) on the other surface are at the same position.

  The 2nd element (9) is formed so that the transmittance | permeability may become higher than a base material (2). Here, high transmittance means that the opacity is low, and that the transmittance is higher than that of the substrate (2) means that the opacity of the substrate (2) is higher than 90%. The second element (9) means that the opacity is 90% or less. The reason why the opacity of the base material (2) is higher than 90% will be described later in detail, but one first element (8) in the first element set (10) is selected. This is because it has a concealing role.

  On the contrary, the reason why the transmittance of the second element (9) is higher than that of the substrate (2) is that the other first element (8) of the first element set (10) is transmitted under the transmitted light. The second element (9) has an opacity of 90% or less, whereas the opacity of the base material (2) is higher than 90%. .

  The method of setting the second element (9) to an opacity of 90% or less may be applied by, for example, squeezing at the paper manufacturing stage if the substrate (2) is a paper sheet. You may give by laser processing or embossing. Alternatively, the second element (9) may be formed by printing a transparent material on paper. As such a transparent material, what mixed synthetic resins, such as polybutadiene, polyisoprene, or polyisobutylene, with the solvent for inks can be used. When a film or plastic is used for the substrate (2), the second element (9) can be formed by laser processing or embossing.

  As shown in FIG. 11A, the second element (9) formed with an opacity of 90% or less is arranged in a line shape in the latent image pattern region (3), and the second element (9) An element group (14) is configured. In the latent image pattern region (3) of the base material (2), the so-called portion of the surface of the base material (2) where the second element group (14) is not formed is referred to as a non-element portion (15). Define.

  When the substrate (2) is a film or plastic with low opacity, the non-element part (15) is formed with printing ink with high opacity, and the second element (9) is non-element part (15). It can be formed with ink or ink density with lower opacity.

The element width (W ₂ ) of the second element (9) is formed in the range of 50 to 500 μm, and the second pitch (P ₂ ) of the second element (9) is 100 to 1000 μm. It is preferable to form in a range. The second pitch (P ₂ ) may be approximately equal to the pitch of the first element set (10), that is, approximately twice the _first pitch (P ₁ ) of the first element (8). Preferably, the element width (W ₂ ) of the second element (9) is narrower than the first pitch (P ₁ ). The reason for this will be described in detail in the visual recognition principle of the transmission latent image pattern (5) visually recognized under transmitted light.

  FIG. 11 (b) shows a cross section taken along line XX ′ of FIG. 11 (a). The second element (9) is inserted and formed by laser processing or embossing. The second element (9) is a recess with respect to the surface of the material (2), and the other part is a non-element part (15). Accordingly, the transmittance of the second element (9) which is a recess is higher than that of the base material (2).

  The shape of the second element (9) can be formed in various shapes as shown in FIGS. 6 to 8, similar to the shape of the first element (8). The transmittance of the first element (8) is higher than that of the base material (2) so that the element (8) can be visually recognized under the transmitted light, and the transmittance is higher than that of the base material (2). The shape is not particularly limited as long as the first element (8) can be visually recognized under light.

(Position relationship and visual recognition principle between the first element and the second element)
Next, the positional relationship and visual recognition principle of the first element (8) and the second element (9) will be described.

  The first element (8) is on top of the second element (9) formed on one side of the substrate (2) or opposite the one side on which the second element (9) is formed. It is formed on the other surface of the side. As described above, since the latent image pattern regions (3) on both surfaces of the base material (2) are at the same position with the base material (2) in between, the first element (8) and the second element ( When 9) is formed on different surfaces, the first element group (11) and the second element group (14) are formed at the same position with the base material (2) interposed therebetween.

Since the second pitch (P ₂ ) of the second element (9) is approximately twice the _first pitch (P ₁ ) of the first element (8), the second element (9) is one of the first elements of the first set of elements (10) (8) (e.g., elements _(8-1) of the first 1a) it has a substantially equal pitch. Therefore, to place one of the elements of the first 1a of the second element (9) and the first set of elements (10) to _(8-1) in the same position. This state is shown in FIG. Fig.12 (a) is the figure which showed the positional relationship of a 1st element group (11) and a 2nd element group (14), and each arrangement | positioning is demonstrated with respect to a base material (2) on description. The figure is shifted in the horizontal direction.

As shown in FIG. 12 (a), by placing one of the elements of the first 1a of the second element (9) and the first set of elements (10) _(8-1) to be the same position, the first the other elements of the 1b of element sets (10) (8 _2), is to be positioned on the non-element part which is between the second element (9) between (15). Figure 12 (a), the although elements of the 1a (8 ₁₎ is in the same position as the second element (9), on the contrary, the elements of the 1b (8 ₂₎ a second element It is good also as the same position as (9). In this case, a component of the 1a (8- ₁₎ is located in the non element portion (15). These relationships mean the negative-positive relationship described above.

  FIG.12 (b) and FIG.12 (c) are figures which show the positional relationship with respect to the base material (2) of the 1st element group (11) and the 2nd element group (14). As described above, the first element group (11) can be formed in two ways with respect to the second element group (14) formed on one surface of the substrate (2). b) shows a state in which the first element group (11) is formed on the second element group (14), and FIG. 12 (c) shows that the second element group (14) is formed. It has shown the state by which the 1st element group (11) is formed in the other surface with respect to one surface of the base material (2) currently made.

  It is possible to form the transmission latent image pattern (5) in the present invention in either of the forms shown in FIGS. 12 (b) and 12 (c). In the following description, as shown in FIG. 12C, the first element group (11) and the second element group (14) are formed on both surfaces with the base material (2) interposed therebetween. I will explain that.

In the state shown in FIG. 12A, FIG. 13A schematically shows a state viewed from one surface where the second element (9) is formed under transmitted light. FIG. 13B is a sectional view taken along line XX ′ in FIG. Since the base material (2) is higher in opacity than 90% and the second element (9) has higher transmittance than the base material (2), so-called opacity of 90% or less, the second one of the elements of the first 1a of the element (9) and the first set of elements which are arranged at the same position (10) _(8-1) includes a first element (8) is formed faces When viewed from the opposite side, it can be confirmed through the second element (9) having a higher transmittance than the base material (2), and the first position located on the base material (2) having an opacity higher than 90%. the other elements of the 1b of the first element set (10) (8 _2), the non-element part (15), so-called, becomes less visible are concealed in the base material (2).

Accordingly, when the latent image pattern region (3) arranged as shown in FIG. 13 (a) is observed from one surface side under transmitted light, it is shown in FIG. 13 (c) via the second element group (14). As described above, the pattern portion (6) formed by _one 1a element (8-1) of the first element set (10) is the first color (12) and the background portion (7) is the second. The transmission latent image pattern (5) of the color (13) can be confirmed.

Here, it will be described that the element width (W ₂ ) of the _second element (9) needs to be narrower than the first pitch (P ₁ ) of the first element (8). To form transparent latent image pattern (5), among the first set of elements (10), elements of the 1a (8 ₁₎ or the element of the 1b only (8 ₂₎ either of Since the second element (9) is arranged at the same position, it is assumed that the element width (W ₂ ) of the _second element (9) is the first pitch (P) of the first element (8). If becomes larger than _1), as shown in FIG. 14, two of the first element to one of the second element (9) is a first set of elements (10) (8 ₁ and 8 _This is because the desired transmission latent image pattern (5) cannot be clearly formed.

Further, the second pitch (P ₂ ) of the second element (9) is approximately twice the first pitch (P ₂ ) of the first element (8), so-called first element set (10 However, even if the pitches are not equal, a plurality of second elements (9) are arranged with respect to the _first element (8-1). ) or from the either one of the elements (8 ₂₎ of the 1b are the same position, but so that the inferior visibility of some transmission latent image pattern (5), transmission latency of colors that Kakari' of the gradient The image pattern (5) can be visually recognized.

The elements of the second element (9) and the 1a (8- ₁₎ shown in FIG. 13 as disposed opposite to the arrangement were the same position, the elements of the 1b (8- ₂₎ a second element ( FIG. 15 shows an arrangement in which 9) is the same position. Fig.15 (a) is a figure at the time of visually recognizing under the transmitted light from the side in which the 2nd element (9) is formed, FIG.15 (b) is XX 'of Fig.15 (a). It is sectional drawing.

As shown in FIG. 15 (a), since the elements of the 1b through the second element (9) (8 ₂₎ is visible, seemed part (6) of a second color (13) The background portion (7) can confirm the transmission latent image pattern (5) of the first color (12). The so-called transmission latent image pattern (5) shown in FIG. 13 has a negative-positive relationship with the transmission latent image pattern (5).

For the purpose of setting the first element set (10) in which the two colors of ink of the first element (8) are arranged corresponding to each other, the first element group (11) is formed as described above. When viewed under reflected light from the lighted side, it is visually recognized as a uniform reflective pattern (4) in which two colors are mixed, and the transmission latent image pattern (5) cannot be confirmed. However, as another object, the first element (8) and the second element (9) are arranged at the same position because the respective element widths (W ₁ and W ₂ ) are fine. A very precise accuracy will be required. Therefore, by the first set of elements (10), even abarelix occurs in printing or processing accuracy, either the first element of the first set of elements (10) (8 ₁ or 8 ₂ ) is in the same position as the second element (9). Therefore, it is possible to form the transmission latent image pattern (5) in the present invention without requiring so much accuracy when manufacturing.

  Further, the arrangement direction of the first element (8) and the second element (9) may be different. Here, the arrangement direction of the first element (8) and the second element (9) will be described with reference to FIG.

FIG. 16A is a diagram illustrating a first direction (T ₁ ) which is an arrangement direction in the first element (8). The first direction (T ₁ ) is a direction perpendicular to the adjacent first element (8) from one point (D ₁ ) of the first element (8). The first element (8) adjacent to the perpendicular passing through D ₁ ) also has a vertical relationship. For a perpendicular passing through one point (D ₁ ) of such a first element (8), all the first elements (8) intersecting the perpendicular have a relationship that is perpendicular to the intersection. . One point (D ₁ ) on the first element (8) has the same relationship with the adjacent first element (8) at any location of the first element (8). The arrangement having such a relationship is arranged in a line in the present invention. Therefore, the first element group (11) as shown in FIG. 16A has the first direction (T ₁ ) regardless of the position (D ₁ ) at any position with respect to the first element (8). ) Is in the same direction.

FIG. 16B is a diagram showing a _second direction (T ₂ ) that is the arrangement direction of the second elements (9), but the second direction (T ₁ ) is similar to the second direction (T ₁ ). element (9) one point on _{(D 2)} is a direction perpendicular to the second element adjacent (9) is that in the second direction _{(T 2),} the point _(D 2) The second elements (9) are arranged in a line with respect to the second direction (T ₂ ) passing through. Therefore, the second element group (14) as shown in FIG. 16B has the second direction (T ₂ ) regardless of the position (D ₂ ) at any position with respect to the second element (9). ) Is in the same direction.

Note that one point (D ₁ ) on the first element (8) and one point (D ₂ ) on the second element (9) are assumed to be “corresponding positions”. Since the first direction (T ₁ ) and the second direction (T ₂ ) are the same for the first element group (11) and the second element group (14) described so far, this 1 point in the first element (8) on _{(D 1)} and the second element (9) one point on _{(D 2)} are those located in the same place.

FIG. 16 (c) shows a state in which the first element group (11) and the second element group (14) are arranged so as to overlap each other. One point (D ₁ ) and one point (D ₂ ) on the second element (9) are located at the same place. Thus, the first direction (T ₁ ) and the second direction (T ₂ ) are divided into one point (D ₁ ) on the first element (8) and one on the second element (9). In the “corresponding position”, the point (D ₂ ) is arranged in a line shape so as to have a vertical relationship.

Here, an example in which the first direction (T ₁ ) is different from the _second direction (T ₂ ) will be described with reference to FIG. FIG. 17A is a diagram in which the arrangement direction of the first element (8) is slightly different from the second element (9), and a part thereof is circled by a dotted line. An enlarged view is shown in FIG. As shown in the enlarged view of FIG. 17B, the first direction (T ₁ ) and the second direction (T ₂ ) are arranged with different angles (α).

As shown in FIG. 17, when the first direction (T ₁ ) and the second direction (T ₂ ) are different, one point (D ₁ ) on the first element (8) and the second element (9 ) One point (D ₂ ) on the “corresponding position” means that if the first direction (T ₁ ) and the second direction (T ₂ ) are equal, as shown in FIG. A state having the same position.

The different angle (α) between the first direction (T ₁ ) and the second direction (T ₂ ) is in the range of 0 to ± 5 ° or less. When the angle is ± 5 ° or more, the transmission latent image pattern (5) formed by the first element (8) that can be visually recognized through the second element (9) does not become a desired pattern. Because it will end up.

Thus, the first direction (T ₁ ), which is the arrangement direction of the first elements (8), is slightly different from the _second direction (T ₂ ), which is the arrangement direction of the second elements (9). Then, the transmission latent image pattern (5) is visually recognized as if a gradation is applied.

(Modification)
The first element (8) and the second element (9) described so far are all linear and parallel lines, but the present invention is not limited thereto. The arrangement is not limited, and the arrangement shown in FIG. 18 is also possible. In FIG. 18A, the first elements (8) are arranged so as to form a polygon from the center to the outside. Such an arrangement of the first elements (8) is also in a state in which a plurality of elements are regularly arranged at a predetermined pitch, so that they are arranged in the “line shape” as referred to in the present invention. It becomes.

  Here, the first element (8) will be described again. As described above, the first element (8) is always composed of the first color (12) and the second color (13). Yes. Since the shape of the first element (8) as described above (for example, FIG. 4 (a)) is a straight line, it is easy to determine the first element (8) one by one. However, the shape as shown in FIG. 18 may cause misunderstanding of how far the first element (8) is formed. In the case of the shape as shown in FIG. 18, an image line having the shape of one polygon (an octagon in FIG. 18) is one first element (8), and constitutes each side of the polygon. The drawn line is not a single first element (8).

Therefore, also in FIG. 18A, the octagonal first elements (8) are arranged in a line, and further arranged in the relationship of the first element set (10). . Also in FIG. 18A, the pattern portion (6) forms “A” and is arranged so as to form the background portion (7) around it. Incidentally, elements of the first in element set (10), one of the first 1a (8- ₁₎ In the second color (13) forms a pattern portion, the other element of the 1b (8- ₂₎ Then, the first color (12) forms the background portion.

FIG. 18B shows a second element group (14) in which the second elements (9) formed with respect to FIG. 18 (a) are arranged in a line. The second element (9) is also an element of one of the 1a in the first set of elements (10) to _(8-1) is visible under transmitted light, hiding the elements of the other of the 1b (8- ₂₎ Therefore, they are arranged so as to form the same polygon as the first element (8).

  When the first element group (11) and the second element group (14) are arranged as shown in FIG. 18 (c) and the latent image pattern area (3) is viewed under transmitted light, FIG. 18 (d) The transmission latent image pattern (5) as shown in FIG.

  In the first element group (11) and the second element group (14) in the present invention, each element constituting each is arranged in a straight line and in parallel as shown in FIG. Needless to say, as described with reference to FIG. 18, it may be formed in a polygon such as an octagon, or may be a circle or an ellipse. However, the shape of the first element group (11) and the shape of the second element group (14) are the same.

Note that the first direction (T ₁ ) and the second direction (T ₂ ) in the case of the arrangement of the first element (8) and the second element (9) as shown in FIG. Will be described. As described above, the first direction (T ₁ ) and the second direction (T ₂ ) indicate directions perpendicular to one point (D ₁ ) on one element. When arranged in a polygonal shape as shown in FIG. 18A, the first element (8) arranged horizontally with respect to the long side direction of the base material (2) is assumed as a reference, and FIG. The vertical direction passing through one point (D ₁ ) of the first element (8) shown in (a) is the first direction (T ₁ ). Thus, for a perpendicular passing through one point (D ₁ ) of the first element (8), all the first elements (8) having intersections with the perpendicular have a perpendicular relationship at the intersection. .

Further, when the first element (8) arranged at an angle of 45 ° with respect to the long side direction of the base material (2) is used as a reference, one point (D on the first element (8) (D _'1) the direction of the vertical through the first direction (T' is _1). Thus, for a perpendicular passing through one point (D ′ ₁ ) of the first element (8), all the first elements (8) having intersections with that perpendicular have a perpendicular relationship at the intersection. Yes.

For each first direction (T ₁ or T ′ ₁ ) shown in FIG. 19 (a), the different angle of the second element (9) is the second direction shown in FIG. 19 (b). (T ₂ or T ′ ₂ ). Also for this second direction (T ₂ or T ′ ₂ ), the vertical direction passing through one point (D ₂ or D ′ ₂ ) on the second element (9) as a reference for determining the direction is the second direction _{(T 2} or T _'2). For any second direction (T ₂ and T ′ ₂ ), the angle with respect to the first direction (T ₁ and T ′ ₁ ) is the first direction (T) as shown in FIG. ₁ ) to the second direction (T ₂ ), and also to the first direction (T ′ ₁ ) as shown in FIG. 19D, the second direction (T ′ ₂ ) Any different angles will be (α).

As described above, since the first element (8) and the second element (9) are regularly arranged in a line, they are in corresponding positions with respect to one point of any element. For one point (D ₁ and D ₂ ) of the first element (8) and the second element (9), the arrangement angle of the first element (8) and the second element (9) The relationship will have the same angle.

  As described above, different angles (α) between the first element group (11) and the second element group (14) arranged in such a polygonal shape are in the range of 0 to ± 5 ° or less. It is preferable to do.

  Regarding the order of printing or processing of the first element (8) and the second element (9), when the second element (9) is formed by squeezing, the second element in the paper manufacturing stage first. (9) is formed by sweeping, and then the first element (8) is formed by printing. Further, when the second element is formed by laser processing or embossing, even if the second element (9) is formed first, the second element (8) is printed after the first element (8) is printed. 9) may be formed either.

  Hereinafter, the formed body (1) according to the present invention will be described in detail with reference to examples. However, the present invention is not limited to the following examples, and any technical scope described in the claims may be used. Needless to say, it can be changed as appropriate.

  In Example 1, the base material (2) was printed on paper, the first element group (11) was printed by the offset printing method, and the second element group (14) was formed by squeezing (1). Was made. The formed body (1) of Example 1 will be described with reference to the drawings described in the embodiment.

  As shown in FIG. 1, the formed body (1) of Example 1 (specifically, a gift certificate) is formed in a part of the latent image pattern region (3) of the base material (2), as shown in FIG. The two-color ink was applied to the surface of the second element group (14) formed by insertion and the base (2) opposite to the second element group (14) by the offset printing method. The first element group (11) printed by using is formed, and in other regions, a product name, a charge character of 1000 yen, and a colored pattern are formed by an offset printing method.

1 is a brown paper having a basis weight of 85 g / m ² , a paper thickness of 87 μm (digital linear gauge DG-925, manufactured by Ono Sokki), and an opacity of 92% (JIS-P8149). The material was used.

In a part of the latent image pattern region (3) of the substrate (2), the second elements (9) shown in FIG. 4 (b) are arranged in a line. This second element (9) was composed of a straight line having an element width (W ₂ ) of 250 μm. The second pitch (P ₂ ) was 500 μm, and a plurality of second elements (9) were regularly arranged in the second direction (T ₂ ) to form the second element group (14). In addition, the formation method of the 2nd element group (14) was formed as a watermark pattern with the circular net paper machine from the one surface side of the base material (2). The opacity of the second element (9) formed by this method was 52% (JIS-P8149). The paper thickness of the second element (9) was 40 μm (digital linear gauge DG-925, manufactured by Ono Sokki).

In the latent image pattern region (3) on the other surface of the substrate (2), the first element group (11) shown in FIG. 4 (a) was formed. The first element group (11) was formed by arranging a plurality of first element sets (10) composed of 1a element (8 _-1 ) and 1b element (8 _-2 ).

The element 1a (8 ₋₁ ) and the element 1b (8 ₋₂ ) had the same element width (W ₁ ) and were configured with a 200 μm straight line. The first pitch (P ₁ ) is 250 μm, and a plurality of 1a elements (8 ₋₁ ) and 1b elements (8 ₋₂ ) are regularly arranged in the first direction (T ₁ ). A first element group (11) was formed. Therefore, the pitch of the first element set (10) is 500 μm, which is equal to the _second pitch (P ₂ ). Further, the first direction (T ₁ ) and the second direction (T ₂ ) are the same direction.

The 1a element (8 _-1 ) uses the offset part (BO special PANTON purple made by T & K TOKA) with the pattern part (6) as the first color (12) and the background part (7) As the second color (13), green offset ink (BO special PANTON green manufactured by T & K TOKA) was used, and printing was performed using an offset printing machine (EP-60 manufactured by Shimogaki Iron Works).

In addition, in order to arrange the 1b element ( _8-2 ) corresponding to the 1a element ( _8-1 ), the same first color (12) and second color (13) ink is used. The pattern portion (6) is composed of the second color (13) and the background portion (7) is composed of the first color (12).

When the first element group (11) having the above configuration is printed on the latent image pattern region (3) at the same position across the second element group (14) and the base material (2), FIG. The 1a element (8 ₋₁ ) is arranged at the same position as the second element (9) as shown.
