  However, when encapsulated in an envelope, this is not a major problem. However, when a digital watermark image or a color two-dimensional code is printed on the inner surface of a crimped postcard, the watermark image or color two-dimensional image is removed when the crimped postcard is removed. The code is transferred to the surface facing the printing surface. For this reason, there is a problem that the digital watermark image and the color two-dimensional code image are missing or faded, and the recorded information cannot be extracted.

  Therefore, the present invention suppresses the transfer of the digital watermark image or the color two-dimensional code when the postcard is peeled off even when the digital watermark image or the color two-dimensional code is printed on the inner surface of the pressure postcard. It is an object of the present invention to provide a method for producing a possible pressure-sensitive postcard paper, pressure-bonded postcard, and pressure-bonded postcard.

The pressure-bonded postcard paper according to the present invention is a first surface that is formed by connecting at least two pieces of paper, that is, a first piece of paper and a second piece of paper through a fold line, and facing each other when folded through the fold line. Pressure sensitive paste is applied to at least one of the opposing surfaces of the one piece of paper and the second piece of paper, and an electronic watermark image in which information is recorded on one of the opposing surfaces of the first piece of paper and the second piece of paper. When the printed information recording image printing layer is formed and two paper pieces are folded by the fold line on a paper piece different from the paper piece on which the information recording image printing layer is formed, the information recording image printing layer Ri Na and transparent ink or peeling varnish is transparent layer applied is formed in the contact position, the superimposed on the information recording image printing layer, it is a second transparent layer transparent ink or peeling varnish is applied is formed That And features.

<1. First Embodiment>
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view showing a crimped postcard paper and a crimped postcard according to the first embodiment of the present invention. In FIG. 1, 1 is a base material, 1a is a first paper piece, 1b is a second paper piece, 2 is an information recording image printing layer, 3 is a transparent layer, and 4 is a fold line.

  1A is a plan view of the pressure-bonded postcard paper, FIG. 1B is a view showing a state where the pressure-bonded postcard paper is folded from the fold line 4, and FIG. 1C is a pressure-bonded postcard paper. Fig. 1 (d) is a diagram showing a state where the crimped postcard is opened and the folded paper pieces are peeled off.

  As shown in FIG. 1 (a), the pressure-bonded postcard paper is divided into a first paper piece 1 a and a second paper piece 1 b by a fold line 4 provided in the center of the substrate 1. That is, the first paper piece 1 a and the second paper piece 1 b are connected via the folding line 4. An information recording image printing layer 2 is formed on the first paper piece 1a. The information recording image printing layer 2 is directly formed on the substrate 1. On the other hand, the transparent layer 3 is formed on the second paper piece 1b. The transparent layer 3 is formed at a position where the information recording image printing layer 2 is in contact with the second paper piece 1b when the first paper piece 1a and the second paper piece 1b are folded by the fold line 4. That is, the transparent layer 3 is formed at a position that is line-symmetric with the information recording image printing layer 2 via the folding line 4. Further, the transparent layer 3 includes a range including all positions where the information recording image printing layer 2 is in contact with the second paper piece 1b when the first paper piece 1a and the second paper piece 1b are folded along the fold line 4 in the plane direction. It is formed. Accordingly, in the example of FIG. 1A, the information recording image printing layer 2 and the transparent layer 3 have the same area, but the area of the transparent layer 3 is larger than the area of the information recording image printing layer 2. It may be formed.

  FIG. 2 is a cross-sectional view showing the manufacturing process of the crimped postcard paper. First, as shown in FIG. 2A, the information recording image printing layer 2 is formed by printing on the surface of the first paper piece 1a in the base material 1 to which the pressure sensitive adhesive is applied. Then, as shown in FIG.2 (b), the transparent layer 3 is formed in the surface of the 2nd paper piece 1b in the base material 1 by printing. The formation position of the transparent layer 3 in the planar direction is a position that is line-symmetric with the information recording image printing layer 2 via the folding line 4 as described above. FIG. 2B shows a case where the areas of the information recording image printing layer 2 and the transparent layer 3 are the same. FIG. 2B is a cross-sectional view taken along line AA in FIG.

  The crimped postcard paper manufactured as described above is folded along the fold line 4 as shown in FIG. 1B, and the opposing surfaces of the first paper piece 1a and the second paper piece 1b are pressure-bonded to each other, as shown in FIG. Crimping postcards as shown in c) are obtained. The crimped postcard is sent to the address indicated and then opened by the recipient. Specifically, the first paper piece 1 a and the second paper piece 1 b are opened by peeling them from the end portion facing the fold line 4. After peeling, as shown in FIG. 1D, the information recording image printing layer 2 of the first paper piece 1a is hardly transferred to the second paper piece 1b because of the protective effect of the transparent layer 3.

  Depending on the characteristics of the ink forming the information recording image printing layer 2, the characteristics of the transparent ink, the printing state thereof, and the like, the information recording image printing layer 2 may be transferred to the second paper piece 1b side. However, the possibility that the image of the information recording image printing layer 2 is destroyed is so low that the information recorded on the information recording image printing layer 2 cannot be extracted. In order to make it difficult for the ink applied to the information recording image printing layer 2 to transfer to the second paper piece 1b side, it is desirable to add a release agent such as silicon to the transparent ink used for the transparent layer 3.

<2. Information Recorded Image Print Layer Image>
As the image of the information recording image printing layer, various known ones can be used as long as they can record information. In the present embodiment, two types of digital watermark and two-dimensional code are employed. “Digital watermark” is a technique for recording specific information in an image, and is formed so that the recorded information is difficult to perceive even when a printed image is viewed. The specific technique of “digital watermark” is not particularly limited, and various known techniques can be used. The “two-dimensional code” is a code having information in the horizontal and vertical directions, and can encode more information than a one-dimensional bar code. As the “two-dimensional code”, various known ones can be adopted, but it is desirable to adopt the most popular QR code (registered trademark). As the QR code, a monochrome code or a color code can be used. Further, a QR code added with a design such as a logo may be used.

<3. Material of each layer>
As the base material 1, a paper coated with a pressure-sensitive adhesive that cannot be re-adhered and removed is used. Various known papers can be adopted as long as they have such characteristics. For example, the pressure-bonded paper described in Patent Document 1 or “infoP mail” manufactured by Hokuetsu Kishu Paper can be used. As a matter of course, the surface to which the pressure-sensitive adhesive paste is applied is used on the side where the folding line 4 is folded and overlapped. The pressure-sensitive adhesive paste is applied to both the first paper piece 1a and the second paper piece 1b, but may be applied to either the first paper piece 1a or the second paper piece 1b.

  When the information recording image printing layer 2 is printed, in the case of monochrome, printing is performed using a single color ink, and in the case of color, printing is appropriately performed using a plurality of colors of ink.

  As the transparent ink constituting the transparent layer 3, it is necessary to use one that does not transfer to the opposite surface when it is pressed and unsealed, or has little transfer by curing. As the transparent ink, various inks that can be cured after application can be used. For example, it is desirable to use “UV BF SG medium” manufactured by DIC Graphic Co., Ltd., which is cured by ultraviolet rays.

<4. Manufacturing method>
Next, a method for manufacturing a crimped postcard will be described. The pressure-bonded postcard according to this embodiment can be manufactured by a manufacturing apparatus in which an information recording image printing unit, a transparent ink application unit, and a folding processing unit are arranged as one line. First, the information recording image printing layer 2 is printed on the first paper piece 1a of the substrate 1 by the information recording image printing unit. Thereby, as shown in FIG. 2A, the information recording image printing layer 2 is formed on the first paper piece 1 a of the substrate 1.

  Subsequently, a transparent ink is applied to the surface of the second paper piece 1 b in the base material 1 by a transparent ink application unit to form a transparent layer 3. Thereby, as shown in FIGS. 1A and 2B, when the transparent layer 3 is folded by the fold line 4, the first paper piece 1a and the second paper piece 1b are folded. 2 is formed in a range including all positions in contact with the second paper piece 1b. The information recording image printing part and the transparent ink application part can be realized by an offset printing machine.

  Subsequently, the folding unit bends the first paper piece 1a and the second paper piece 1b from the fold line 4 and applies pressure to the first paper piece 1a and the second paper piece 1b, whereby the first paper piece 1a and the second paper piece 1b. Crimp the opposing surfaces. That is, a crimping postcard as shown in FIG. 1C is obtained by bending as shown in FIG.

<5. Use of crimped postcards>
The crimping postcard shown in FIG. 1C is sent to the recipient. When the recipient opens the postcard, the information recording image printing layer 2 on the first paper piece 1a is not transferred to the second paper piece 1b. Even if a part of the image is transferred, the image on the information recording image printing layer 2 is not greatly damaged. After opening the user, for example, the information recording image print layer 2 is photographed with a camera-equipped cellular phone, and the program embedded in the camera-equipped cellular phone is executed on the photographed image, and a digital watermark extraction process, two-dimensional code Recognition processing or the like is performed, and information recorded in the information recording image is extracted.

<6. Second Embodiment>
Next, a second embodiment of the present invention will be described.
FIG. 3 is a plan view showing a crimped postcard paper and a crimped postcard according to the second embodiment of the present invention. In FIG. 3, the same parts as those in FIG. In FIG. 3, 5 is a 2nd transparent layer. The second embodiment is different from the first embodiment in that the second transparent layer 5 is provided.

FIG. 3D is a diagram showing a state in which the crimped postcard is opened and the folded paper pieces are separated from each other.

  As shown in FIG. 3A, an information recording image printing layer 2 and a second transparent layer 5 are formed on the first paper piece 1a. The second transparent layer 5 is formed by printing transparent ink from the upper side (front side in FIG. 3) of the information recording image printing layer 2. The second transparent layer 5 is formed in the same range as the information recording image printing layer 2 or in a wider range including the information recording image printing layer 2 in the planar direction. In the example of FIG. 3, it is formed in a wider range including the information recording image printing layer 2. Therefore, when viewed from above, as shown in FIG. 3A, the information recording image printing layer 2 can be visually recognized through the second transparent layer 5, and the second transparent layer 5 is formed around the information recording image printing layer 2. Will also spread.

  FIG. 4 is a cross-sectional view showing the manufacturing process of the crimped postcard paper according to the second embodiment. First, as shown in FIG. 4A, the information recording image printing layer 2 is formed by printing on the surface of the first paper piece 1a in the base material 1 to which the pressure sensitive adhesive is applied. Then, as shown in FIG.4 (b), the transparent layer 3 is formed by printing on the surface of the 2nd paper piece 1b in the base material 1. FIG. In the second embodiment, simultaneously with the formation of the transparent layer 3, the second transparent layer 5 is formed on the surface of the information recording image printing layer 2 by printing. The formation range of the second transparent layer 5 in the planar direction includes the entire information recording image printing layer 2 and is the same as or wider than the information recording image printing layer 2. When it is wider than the information recording image printing layer 2, as shown in FIG. 4B, the second transparent layer 5 is directly formed on the surface of the first paper piece 1a in the area where the information recording image printing layer 2 does not exist. . FIG. 4B is a cross-sectional view taken along the line BB in FIG.

  The crimped postcard paper produced as described above is folded along the fold line 4 as shown in FIG. 3B, and the opposing surfaces of the first paper piece 1a and the second paper piece 1b are pressure-bonded to each other, as shown in FIG. Crimping postcards as shown in c) are obtained. The crimped postcard is sent to the address indicated and then opened by the recipient. Specifically, the first paper piece 1 a and the second paper piece 1 b are opened by peeling them from the end portion facing the fold line 4. After peeling, as shown in FIG. 3D, the information recording image printing layer 2 of the first paper piece 1a is almost transferred to the second paper piece 1b because of the protective effect of the transparent layer 3 and the second transparent layer 5. Not.

  In the second embodiment, in addition to the transparent layer 3, the second transparent layer 5 is further provided. Therefore, compared to the first embodiment, the ink for forming the information recording image printing layer 2 toward the second paper piece 1 b side. Can be made more difficult to transfer. In order to make it difficult for the ink applied to the information recording image printing layer 2 to transfer to the second paper piece 1b side, a release agent such as silicon is added to the transparent ink used for the second transparent layer 5 as well as the transparent layer 3. It is desirable.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above-described embodiment, the pressure-bonded postcard is composed of two paper pieces, the first paper piece 1a and the second paper piece 1b, but it may be a pressure-bonded postcard composed of three or more paper pieces.

  In the above embodiment, the case where the information recording image printing layer 2 is formed only at one place on the pressure-bonded postcard has been described. However, the information recording image printing layers 2 are provided at a plurality of places so as not to overlap each other on the first paper piece 1a. You may make it form. In this case, the transparent layer 3 and the second transparent layer 5 may be formed at positions on the second paper piece 1b facing the respective information recording image printing layers 2, or a plurality of information recording image printing layers 2 may be formed. One transparent layer 3 and second transparent layer 5 may be formed so as to cover the entire position on the opposing second paper piece 1b.

  Moreover, in the said embodiment, although the transparent layer 3 and the 2nd transparent layer 5 were formed by apply | coating transparent ink, it seems that the transparent layer 3 and the 2nd transparent layer 5 are formed by apply | coating a transparent peeling varnish. Anyway.
