<1. Basic configuration>
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 an 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 ink 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. 1D is a diagram showing a state where the crimped postcard is opened and the folded pieces of paper are separated from each other.

  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 and a transparent ink layer 3 are formed on the first paper piece 1a. The information recording image printing layer 2 is directly formed on the substrate 1, and the transparent ink layer 3 is formed by printing transparent ink from the upper side (front side in FIG. 1) of the information recording image printing layer 2. The transparent ink layer 3 is formed in a wider range including the information recording image printing layer 2 in the planar direction. Therefore, when viewed from the top, the information recording image printing layer 2 can be visually recognized through the transparent ink as shown in FIG. 1A and spreads around the transparent ink layer 3 and the information recording image printing layer 2. Become.

  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. Subsequently, the transparent ink layer 3 is formed on the surface of the information recording image printing layer 2 by printing. The formation range of the transparent ink layer 3 in the planar direction includes all of the information recording image printing layer 2 and is wider than the information recording image printing layer 2. Therefore, as shown in FIG. 2B, the transparent ink layer 3 is formed directly on the surface of the first paper piece 1a in the area where the information recording image printing layer 2 does not exist. FIG. 2B is a cross-sectional view taken along line AA in FIG.

  The crimped postcard paper manufactured in this way 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 FIG. 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. 1 (d), 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 ink layer.

  Depending on the characteristics of the ink forming the information recording image printing layer, 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.

<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 ink layer 3, it is necessary to use one that does not transfer to the opposite surface during pressure bonding and opening of the pressure-bonded postcard or that 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.

  Then, the transparent ink layer 3 is apply | coated by a transparent ink application part so that the information recording image printing layer 2 of the 1st paper piece 1a may be covered. Thereby, the transparent ink layer 3 is formed in the upper layer of the information recording image printing layer 2 as shown in FIGS. 1 (a) and 2 (b). As described above, the transparent ink layer 3 is directly formed on the first paper piece 1a in the region where the information recording image printing layer 2 is not formed. 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, a two-dimensional code is executed. Recognition processing or the like is performed, and information recorded in the information recording image is extracted.

  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 embodiment, the pressure-bonded postcard is composed of two pieces of paper, that is, a first paper piece and a second paper piece, 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 layer 2 is formed at a plurality of places so as not to overlap each other on the piece of paper. Anyway. In this case, a plurality of transparent ink layers 3 may be formed so as to cover each information recording image printing layer 2, or one transparent ink layer 3 may be formed so as to cover the entire plurality of information recording image printing layers 2. You may do it.

  The pressure-sensitive postcard paper and pressure-bonded postcard of the present invention can treat the information printed on the inside as a secret and can be used as a simple delivery.
