[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter having a copy protection function (copying prevention function) which is extremely useful in the field of management of documents, etc. where copy is unfavorable, and a manufacturing method thereof.

[0002]

BACKGROUND OF THE INVENTION Recently, the spread of copying machines has been remarkable, and it is used not only in schools, libraries, but also in most offices, whether public or private, as well as convenience stores. And so on. This seems to be due to the convenience of being able to easily copy as many original editions as necessary, but for example, in the case of design drawings of machines and devices and internal documents where confidentiality is important, There are some things that are annoying if duplicated.

However, the performance of the copying machine has also made a great leap forward. For example, even if an original plate is prepared with ink of a color tone such as a fluorescent color which cannot be captured by a photosensitive sensor in a conventional copying machine, it is the latest. When using this copying machine, it is easily detected and duplicated. Therefore, in the case of the original plate that does not like copying as described above, how to manage the original plate and prevent the appearance of so-called pirated plates is an important problem to be solved.

[0004]

Technical matters attempted to be solved The present invention has been devised in view of the background described above in order to solve the above problems, and to develop an ink itself which cannot be detected by any copying machine. The present invention proposes a printed matter having a novel copy protection function and a method for producing the same, which is an alternative to the conventional viewpoint of finding a printing method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A printed matter having a copy protection function of the present invention and a method for manufacturing the same will be specifically described below with reference to the drawings. In the following description, the method for producing a printed matter having a copy protection function of the present invention will be described by dividing it into three steps: (i) selection of a printing substrate, (ii) formation of a printed material, and (iii) formation of a pattern. At the same time, in the description, the structure of the printed matter having the copy protection function of the present invention as a result thereof will be described.

(I) Selection of Printing Base Material First, the printing base material 2 to be printed is selected. The printing substrate 2 that can be used in the present invention is most preferably a paper having smoothness such as art paper, but it is possible to print a printing medium 3 and a printing pattern 5 or a blank pattern 6 described later, which will be described later. Various materials can be selected as long as the effects of the invention can be reproduced. Therefore, as long as the above conditions are satisfied, a printing substrate having various materials and thicknesses, such as a film made of synthetic resin or glass fiber, a sheet-shaped member, or even a thin metal plate having a slightly thicker thickness than this. 2 can be selected.

(Ii) Formation of Printed Ground Next, when printing a print pattern 5 or a blank pattern 6 which will be described later, is printed on the print base material 2, a print background 3 which is a base thereof is formed. First, for the purpose of improving the smoothness of the surface of the printing substrate 2 to facilitate the printing of the matte ink described below, and to conceal stains, stains, etc. on the surface of the printing substrate 2. Thus, the base 4 is formed.

Therefore, when the printing substrate 2 itself has a desired smoothness, the formation of the underlayer 4 is not always necessary. On the contrary, when there is some difficulty in the smoothness of the printing substrate 2, the formation of the base 4 is an essential requirement.

In forming the base 4, it is desirable that the base ink of an appropriate color is applied to the printing substrate 2 at least twice and printed. This is also for improving the smoothness of the printing substrate 2. Therefore, when there is a problem in the smoothness of the printing substrate 2, it is possible to apply the undercoat ink more times to obtain the desired smoothness.

The color of the base ink can be set to an appropriate color as described above, but the visual recognition by the naked eye of the pattern A brought about by the combination of the matting ink and the glossing ink described later is remarkably impaired. We will refrain from adopting colors that can be applied. In addition, in this example, a black ink and a base ink of a brownish color similar to the matte ink and the matte ink were used.

Then, as shown in FIG. 3, the matte ink, which is a characteristic feature of the present invention, is printed on the base 4 thus formed to form the printed material 3. Although it is possible to select various colors of the matte ink, preferably, a blackish brown color is selected, and at least the visibility of the pattern A brought about by the combination with the matte ink described below becomes good with the naked eye. Choose a color like

(Iii) Formation of a pattern Then, as shown in FIGS. 4 and 5, a glossing ink which is another characteristic construction of the present invention is printed on the printed material 3 to form a pattern A. . As a method of forming the pattern A, for example, two methods are conceivable, and one of them is a method of using the print pattern 5 which itself constitutes the pattern A as shown in FIG. Incidentally, in this case, the portion of the pattern A has gloss, and the other portion (background, etc.) has a state in which the printed material 3 having no gloss is exposed.

Another method is to use a pattern A as shown in FIG.
This is a method of using the punching pattern 6 in which the glossing ink is not applied at all to the part constituting the. Incidentally, in this case, the surface of the printed material 3 having no gloss appears in the portion of the pattern A, while the other portions (background and the like) have the gloss.

As the color of the matte ink used for forming the pattern A, a black color or a brown color is preferably selected in the same manner as the matte ink, and at least a combination with the matte ink is used. The color is selected so that the resulting pattern A has good visibility with the naked eye, and at the same time, the same color as the printed material 3 (specifically, a matte ink) is used so that the pattern A cannot be exposed during copying. Select the color of.

When forming the print pattern 5 or the blank pattern 6, a screen mesh coarser than the standard specifications is used. This is to make the contrast between the glossy ink and the printed material 3 more remarkable. Although the manufacturing method of the present invention is configured in this manner, contrary to the above-described embodiment, in forming the printed material 3, glossy ink is used to form the printed pattern 5 or the blank pattern 6. It is of course possible to use a matte ink for this purpose.

The printed matter 1 having the copy protection function of the present invention is produced as a result of the production method of the present invention. 1 is a printed matter 1 having the copy protection function of the present invention.
However, the pattern A expressed in the printed matter 1 is not limited to the pictorial pattern as shown in the drawing, but characters and various symbols,
Alternatively, it is possible to employ various visual expression media such as a design drawing in which these are combined, other figures and geometric patterns, and further landscapes and people by photolithography.

[0028]

The printed matter having the copy protection function and the method for producing the same according to the present invention are constituted by having the above-mentioned constitution, and by having such constitution, the following effects can be obtained. To be demonstrated. That is, the printed matter 1 having the copy protection function according to claim 1 is formed on the printed material 3 on which the matte printing has been performed by the glossy printing with the printed pattern 5 or the blank pattern 6 of the same color as the printed material 3. Take the configuration. As a result, the pattern A represented by the combination of the two kinds of inks laminated can be exposed by the naked eye due to the difference in gloss, and the two kinds of inks have the same color.
Even if this is copied by a copying machine, the design does not appear in the copy.

A printed matter 1 having a copy protection function according to a second aspect of the present invention is formed by printing the printed material 3 by applying the base ink twice and then printing the matte ink. As a result, the smoothness of the surface of the printing substrate 2 before printing the matte ink is increased, and printing of the matte ink becomes easy.

The printed matter 1 having the copy protection function according to the third aspect is configured such that the color of the printed material 3 is black. As a result, it becomes even more difficult to distinguish the printed pattern 5 or the printed pattern 6 having the same color as the printed material 3 by the copying machine.

According to the method for producing a printed matter having a copy protection function according to claims 4 to 7, in addition to the effects brought about by the printed matter 1 according to claims 1 to 3, a screen mesh coarser than the standard specifications in glossy printing is provided. By using, the glossy expression appears more conspicuously,
The visibility of the design is improved with the naked eye. The synergistic effects of these effects can reduce the burden of management of documents and the like that are unwelcome to copy, and prevent the appearance of pirated copies.
