Abstract

PURPOSE:To make mass production possible by a method wherein printing in a latent image state is heated and pressed by a heating and press bonding means for development and fixing and the folding of base paper is made complete and superposed transparent films are mutually adhered falsely. CONSTITUTION:Primary printing is applied to the long base paper delivered from a roll to print unchangeable data 2 on the base paper 1 and, thereafter, a dry silver salt photosensitive emulsion is applied to the entire surface of the base paper and dried to form a silver salt photosensitive layer 3. Subsequently, a self-adhesive transparent film 5 is placed on the base paper and a perforation is applied to the base paper and the film so as to pierce both of them. In this state, individual variable data 4 is printed on the photosensitive layer 3 by a continuous printing system due to the output of a computer while the photosensitive layer is irradiated with semiconductor laser beam on the side of the film. After the printing of the variable data 4 is completed, the laminate is cut off along the perforation at every data unit and further folded into a size of a postcard to superpose the transparent films mutually and bonded under heating and pressure by a heating roller. By this method, since printing is directly performed by the output of the computer due to laser beam, a manufacturing time can be shortened.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is a system that uses constant information common to all recipients (common phrases, lines, frames, patterns, figures, etc.).

The present invention relates to an information laminate displaying variable information that is individual and thus requires secrecy in a concealed state, and a method for producing the same. Typical information laminates are postal items such as postcards and envelopes, but recently their application fields are expanding to include personal cards, catalogs, and product and company guides. In the following explanation, postcards, which have strict regulations regarding shape, weight, and size, will be used as a representative example.

(Prior Art) Recently, there have been increasing opportunities for companies to communicate confidential information to their employees, and for banks and credit companies to communicate confidential information to their customers.

However, on the other hand, there is also a strong social need to protect personal secrets.
How to secretly notify important personal information is a major challenge for senders. For this reason, a simple single postcard is not suitable; either an old-fashioned sealed letter, or two sheets of paper with information printed on the inside and glued together, and the recipient can use scissors along the cut-off line. The package is opened by cutting or cutting along pre-set perforations.

(Problem to be solved by the invention) When using sealed letters, it takes time and effort to put a large amount of documents into an envelope. However, due to concerns about personal information being leaked, it cannot be outsourced to outsiders, and there is the inconvenience that only a limited number of personnel can handle the work. Moreover, the shipping costs are quite high due to the large quantity. Furthermore, if the edges of the document are glued or perforated, it not only burdens the producer, but also requires the recipient to cut out the edges with scissors or cut along the perforations. The cut edges become waste, so it takes time to dispose of them each time.

In view of these problems, the present invention aims to enable mass production of information stacks for which confidentiality is an absolute requirement.

(Means for Solving the Problems) In order to achieve the above object, according to a first aspect, permanent information is printed on the display surface of a mount, then a silver salt photosensitive agent is applied to the mount, and the same Once the photosensitive layer is dry, a transparent film is permanently bonded on top of it, and then cut-off lines and folding lines that pass through the mount and transparent film are provided at predetermined locations.Finally, a computer is applied to the transparent film using a laser beam as a light source. By outputting, variable information is printed for each information unit, and the transparent films are overlapped by folding along the folding line, and heat and pressure are applied by a heat and pressure bonding means to develop and fix the print, and the folding is thoroughly performed, The stacked transparent films are pseudo-adhered to each other, and then cut out along the cutting line to form a single piece.

According to the second aspect, a silver salt photosensitive agent is applied to the display surface of the mount, permanent information is printed on the same photosensitive layer, a transparent film is permanently adhered thereon, and then the mount/transparent film is attached. Cut-through lines and folding lines are provided at predetermined locations, and finally, variable information is printed on the photosensitive layer for each information unit by computer output using a laser beam as a light source from the transparent film side, and folded along the folding lines. The transparent films are superimposed on each other, and the printed characters are developed and fixed by applying heat and pressure using a heating and pressure bonding means, and the folding process is thoroughly performed, and the superimposed transparent films are pseudo-adhered, and then the transparent films are pasted together along the cutting line. It is cut out and made into a single piece.

Furthermore, according to a third aspect, a silver salt photosensitive agent is applied to the display surface of one mount, a transparent film is permanently adhered thereon, and then the cut-off line and folding line passing through the mount and the transparent film are inserted at predetermined locations. Finally, the photosensitive layer 5 is coated with a computer output using laser light as a light source from the transparent film side.
Immutable information and variable information are printed on the transparent film, and the transparent films are overlapped by folding along the folding line, and the printing is developed and fixed by applying heat and pressure using a thermocompression bonding means, and the folding is thoroughly performed, and the transparent films are overlapped. The combined transparent films are pseudo-adhered to each other, and then cut out along the cutting line to form a single piece.

(Function) In order to develop and fix the print in the latent image state, by heating and applying pressure using a heat pressure bonding means, not only the print is developed and fixed, but at the same time the backing paper is thoroughly folded and the superimposed transparent The films are pseudo-adhered to each other.

(Example) FIGS. 1A, 1B, and 1C schematically show embodiments of the present invention, which will be described in detail below. In addition,
Each example deals with postcards.

Example (1) In FIG. 1(A), primary printing was performed on a long mount 1 unrolled from a roll by a normal form printing method, and permanent information 2 was printed on the mount 1.

A dry silver salt photosensitive emulsion was applied onto the entire surface of the mount and dried to form a silver salt photosensitive layer 3. Next, a self-adhesive transparent film 5 was placed on a mount using a dry silver salt photosensitive emulsion under the trade name "Dry Silver" (manufactured by Sumitomo 3M Ltd.), and perforations were made through the mount and film using a well-known method. (not shown) was inserted. In addition, the code|symbol 6 shows an adhesive layer.

If the film has no self-rejuvenating power, apply adhesive and use Adhesive W! The film 5 may be placed after forming J6. In this state, individual variable information 4 was printed on the photosensitive layer 3 by a continuous printing method using computer output while irradiating semiconductor laser light from the film side in the direction of the arrow. The dry silver salt photosensitive emulsion need not be applied to the entire surface of the mount, but may be applied only to the areas where the information remains unchanged.

In addition to the above photosensitizers, the product name is "Dry Copics".
(manufactured by Oriental Photo Industry Co., Ltd.) was also used, but there was almost no difference in the results.

Furthermore, it is convenient to use Siltsuba heat-developable silver salt photosensitizer (Asahi Kasei Kogyo Co., Ltd. 1), which does not exhibit photosensitivity until preheated, because it can be used under a normal light source such as a fluorescent lamp.

After printing of the variable information 4 was completed, each information unit was cut out along the perforations, folded into the size of a postcard, and the transparent films were superimposed on each other, and then heated and pressed using a heat roller. As a result, the printing is clearly developed, and permanent adhesion of the transparent film to the mount side and pseudo adhesion of the overlapped films are thoroughly ensured, and there are no gaps on the mating surfaces, which are considered unsuitable for mailing, and they are perfectly aligned. It ended up being a postcard. The mount 1 does not have to be long, and may be a single sheet that is continuously fed. The temperature and pressure of the heat roller are determined as appropriate depending on the properties, thickness, and feed speed of the film. Average temperature is 90-150'C, press pressure is 4K
It is about g. As the heating and pressing means, not only a heat roller but also a heat plate or a heat iron can be used.

Example (2) In FIG. 1 (b), before primary printing is performed on the long mount 1 unrolled from the roll, the above-mentioned "Dry Silver", which is a dry silver salt photosensitive emulsion, is applied and dried to form the photosensitive layer 3. is formed, and permanent information 2 is printed on it. The subsequent steps are the same as in Example (1).

Example (3) Unlike the above two sides, a mount 1, a photosensitive layer 3, a transparent film 5
After shaping, primary and secondary printing was performed using computer output using laser light as the light source. As mentioned above, in the case of a transparent film that does not have self-adhesive properties, there is a step of applying an adhesive.

The subsequent steps are the same as in Example (1).

FIG. 2 shows an example of folding the information laminate in half to make a postcard. In the illustrated embodiment, the folding line 10 is provided at the center so as to equally divide the information display surface into two parts. However, if they are divided unevenly and overlapped, the shifted portion becomes a step and becomes a gripping margin when peeling off the pseudo-adhesive film, which is convenient. The photosensitive layer 3 is formed on the entire information display surface, and the transparent film is also permanently adhered to the entire surface. The transparent film is folded in half, the inner surfaces of the transparent film are overlapped, and a pseudo-adhesion is applied by heat and pressure bonding.

FIG. 3 shows another modification, in which the information stack is folded into three (two-fold) to form a postcard. Two folding lines 10 are provided so that the information display surface can be equally divided into three sections. As shown in FIG. 3(a), the photosensitive layer 3 is formed on the entire information display surface, but the transparent film 5 is permanently bonded only to two continuous surfaces on the right side in the figure. FIG. 3(b) shows the back side of the folded sheet. Heat-sensitive adhesive is applied to the two continuous sides on the left side, and the folded sheet is folded in from the fold line on the left side, permanently adhering both sides to form substantially the same form as folded in two. but.

Instead of heat-sensitive adhesive, a transparent film can be permanently attached to create a pseudo-adhesion when the two sides are overlapped, and both sides can also be used as information display surfaces. In this way, the entire surface can be used as an information display surface in the illustrated state. In the illustrated embodiment, the sections are evenly divided, but as described above, it is also possible to divide the section into three unevenly to create a step (grasping margin).

(Effects of the Invention) Since at least the secondary printing is performed directly by computer output using laser light, the production time is significantly shortened. In particular, as in the method of embodiment (3), the production time can be shortened by performing the second and second printing at the same time. Thorough folding is achieved by heat-pressing means for development,
In addition, pseudo-adhesion between the overlapped transparent films is reliably achieved. Moreover, since the surface of the transparent film that is permanently bonded to the backing paper is flattened by pressure, there is no need to worry about the mail being disqualified due to voids created inside, even in the case of mail items that have strict regulations.
