BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a see-through preventing printed matter.

[0002]

2. Description of the Related Art Some documents, such as real estate titles and stock certificates, have absolute significance in possession of the document itself, and it is most important to protect the document from theft, fire, etc. This is an important issue. However, while possession of some documents is important, it is difficult to leak the contents of the documents. In such a document, if the appearance of the document is abnormal, it may be understood that the content may have been leaked, and it may be possible to take countermeasures, but if the content is leaked by a method of seeing through without leaving any trace on the appearance. Is the worst thing to do because the owner of the document does not even know the fact of the leak. For this reason, document owners have worked hard to improve the document itself so that it cannot be seen through, and to thoroughly manage the document so that it cannot be seen by a third party. An example of the latter effort to ensure document control is the so-called triangle lottery. The triangular lottery is obtained by folding a rectangular piece of paper indicating a hit into two pieces along a diagonal line and pasting the peripheral edge to conceal the indication of the hit, and peeling off the peripheral edge to see the hit. is there. In many cases, the triangular lottery is printed on the outer surface with a relatively dark color tone, and if the user uses the triangular lottery in a normal manner, the display of the hit is not seen through. However, if the lottery takes the triangle lottery home and shines a strong light, it can be easily seen through. For this reason, the lottery managers take care of the lottery and always open it in front of them. for that reason,
This triangle lottery is relatively narrow such that a lottery issuer can even manage the opening of a lottery, for example, a street shopping association issues a lottery and each retailer manages the opening of the lottery. Although it is suitable for use in a local area, it is not very suitable for use in a wide area where a major manufacturer issues a product sales campaign or the like and entrusts opening to supermarkets and retail stores. That is, there is generally a limit to ensuring thorough document management. Therefore, it is expected that the former document itself cannot be seen through, and so-called scratch cards have recently been used. The scratch card is formed by forming a paint layer of silver or the like on the display of the hit, correct answer, etc. to conceal the display of the hit, correct answer, etc., and rubbing the paint layer with a coin or the like to remove the hit, correct, etc. Is what you see. Manufacturers of cosmetics, food, electrical equipment, and the like often hand this telephone card to merchandise buyers as a lottery with a telephone card or the like attached to a prize for a sales promotion campaign or the like.

[0003]

However, there is a problem that it has recently been found that a scratch card, which has been believed to be absolutely impossible to see through, can be seen through strong light such as an incandescent lamp.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been devised to solve the above-mentioned problems, and is an anti-transparent printed matter in which a non-transparent printed matter is covered with a concealing layer on a display provided on a sheet-like material. A halftone dot is provided in a portion of the sheet-like material which is covered by the concealing layer, and the display is formed by a halftone dot which is different in color from other halftone dots and blocks light to the same extent.

[0005]

In the see-through preventing printed matter of the present invention, all halftone dots appear as uniform shadows even when incandescent lamps or the like are applied.

[0006]

FIG. 2 is a plan view of a scratch card as an example of the see-through preventing printed matter according to the present invention, as viewed from the front side.
The basic structure and usage of this scratch card are exactly the same as those of a normal scratch card, and a correct answer and an incorrect answer pattern 2 as an example of display are printed on the surface of a sheet of paper 1 as an example of a sheet. A silver paint layer 3 as an example of a hiding layer is provided on each pattern 2 by printing. In this embodiment, as is clear from the figure, four patterns 2 are arranged in four rows in each row and three rows in the upper and lower rows, and the paint layer 3 is printed in a square shape covering each pattern 2.
Then, one of the hit patterns 2 is included in each of the four patterns 2 of each stage, and the person drawing the lottery cuts only one of the four paint layers 3 of each stage with a coin or the like. The winning patterns 2 are exposed one by one from each stage, and the entire lottery is hit when only a total of three winning patterns 2 are exposed. That is, when only the cross-shaped pattern 2 shown by the two-dot chain line in FIG. According to the present invention, a halftone dot is provided in a portion of the scratch card paper 1 which is covered by the paint layer 3, and the pattern 2 is formed by a halftone dot which is different in color from other halftone dots and blocks light to the same extent. (Hereinafter referred to as a main part), and such a main part can be formed as follows.

(Embodiment 1) A main portion is formed by forming halftone dots of pattern 2 and other halftone dots with similar colors which are different but similar in color, for example, yellow and orange. Can be done. FIG. 1 shows an embodiment of the invention, in which a pattern 2 before a coating layer 3 is provided.
Is shown. In the figure, 4 is a yellow dot, and 7 is an orange dot. The halftone dot 7 forms a cross pattern 2. In the present embodiment, the halftone dot 4 and the halftone dot 7 are different in color between yellow and orange, so that the cross-shaped pattern 2 can be clearly recognized. Further, when the incandescent lamp or the like is applied after the silver paint layer 3 is provided and the scratch card is formed, the yellow dot 4
And the orange halftone dot 7 block the light of the incandescent lamp to substantially the same extent. Therefore, both the yellow halftone dot 4 and the orange halftone dot 7 appear as shadows of the same darkness, and it is impossible to distinguish between them. That is, it is impossible to see through the pattern 2 at all, since only uniform dots appear to be scattered throughout.

(Embodiment 2) A main portion forms a plain net with relatively dark halftone dots such as black, for example, and the other half of the plain net is not darker than the halftone dot. It can be formed by overlapping color dots. 1 and 3 show one embodiment of the present invention, and FIG.
Shows a pattern 2 before the paint layer 3 is provided, and FIG. 2 shows a cross section after the paint layer 3 is provided. In forming the pattern 2, first, as shown in FIGS. 1 and 3, black dots 4 are printed on the entire portion of the paper 1 to be concealed by the paint layer 3 to form a plain mesh 5. Next, white dots 6 are overprinted on a part of the halftone dots 4 of the plain screen 5 to form a white pattern having the same size as the pattern 2. Next, a red halftone dot 7 is printed on the halftone dot 6 to form a red pattern 2. In this embodiment, the halftone dot 4 and the halftone dot 7 are different in color between black and red, so that the cross-shaped pattern 2 can be clearly recognized. Further, when the incandescent lamp or the like is applied after the silver paint layer 3 is provided to form a scratch card, the portion where the dots 4, 6, and 7 overlap and the portion of the dot 4 substantially match the light of the incandescent lamp. Shield to a degree. Therefore, the portion where the dots 4, 6 and 7 overlap and the portion of the dot 4 both appear as shadows of the same darkness, and it is impossible to distinguish them. That is, it is impossible to see through the pattern 2 at all, since only uniform dots appear to be scattered throughout. In the present embodiment, the white dots 6 are used, but the dots 6 may be omitted and the dots 7 may be printed directly on the dots 4. Further, the halftone dots 4, 6, and 7 are such that the halftone dot 7 is the halftone dot 4
Any color may be used as long as it is not darker and the halftone dot 6 is a color close to white.

The present invention is not limited to the above embodiment, but may be, for example, as follows. 1) The halftone dots 4, 6, and 7 may be provided by letterpress printing, offset printing, gravure printing, silk screen printing, or any other printing method. In particular, by using a compact printing machine, the applicable range of the present invention is dramatically increased as shown in 4) below. 2) The sizes of the halftone dots 4, 6, and 7 are appropriately determined in accordance with the type of printed matter, such as the type and mode of display of characters and pictures, the type of sheet material, and the like. 3) The sheet material may be other than paper, for example, a plastic sheet material. 4) The present invention can be widely applied to general documents that cannot be seen through, and is particularly suitable for the following documents. Documents requiring confidentiality for a certain period of time (Example) Confidential agreements between nations, confidential agreements between private companies, wills Letters requiring privacy protection (Examples) Notices, notices of seizures, notices of test results , Various survey reports lottery, quizzes

[0010]

The present invention is configured as described above, and when the concealment layer is removed, the halftone dots of the display are different in color from the surrounding halftone dots, so that the display can be clearly recognized. In addition, even when light such as an incandescent light is applied, the halftone dots of the display and the surrounding halftones block the light to the same extent, so that the halftone dots of the display and the surrounding halftone dots appear as shadows of exactly the same darkness. This has the effect of preventing see-through.
Therefore, it is not necessary to be very nervous in managing the documents, and the storage and transportation of the documents can be performed extremely easily, and evidence documents that need to be confidential for a certain period, correspondence documents that need to protect privacy, lottery, etc. , Quizzes, etc.
It can be used very widely.
