As a result, the crimes of copying and misusing the originals such as seals and signatures used in bankbooks, securities, checks, etc. are made without any modification.

In the prior art, means for preventing the forgery and alteration of the originals such as imprints and signatures have been proposed as above, but the effective prevention means for forgery using the above copying machine, printing machine, etc. There were no steps.

The present invention is intended to solve the above-mentioned problems, and it is an object of the present invention to make it possible to easily discriminate a copied product by copying a seal impression, a signature, or the like.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a transparent or semi-transparent cover sheet that covers the surface of an object for the purpose of preventing forgery, and forms an adhesive layer for fastening on the back surface of this cover sheet. At the same time, the cover sheet is provided with a semi-transparent printing part through which at least a part of the covered object can be seen through, and the semi-transparent printing part is formed narrower than the object.

A second invention is to provide a transparent or translucent covering sheet for covering the surface of an object for anti-counterfeiting purpose, and to form a pressure-sensitive adhesive layer for fastening on the back surface of this covering sheet and to coat the object. A sheet is provided with a semi-transparent printing part through which at least a part of the covered object can be seen through, and the semi-transparent printing part is formed by characters, figures, symbols, and patterns with white outlines. .

A third invention is to provide a transparent or translucent covering sheet for covering the surface of an object for anti-counterfeiting purpose, and to form an adhesive layer for fastening on the back surface of the covering sheet and to cover the object. The sheet is provided with a semi-transparent printing portion through which at least a part of the covered object can be seen through, and the semi-transparent printing portion is formed by characters, figures, symbols and patterns.

The semi-transparent printing portion may be formed by displaying one straight line that is narrower than the object.

The semi-transparent printing section may be formed by displaying a plurality of straight lines that are narrower than the object.

[0011]

[Action]

 The present invention is configured as described above, and in order to use the present invention, an object for the purpose of preventing forgery such as a seal imprint and a sign is covered with a covering sheet. This coating is performed so that the pressure-sensitive adhesive layer is located on the side of the target portion, and the semi-transparent printed portion overlaps the object.

Since the printing portion is formed to be semi-transparent so that at least a part of the covered imprint, signature or the like can be seen through, it may cause a problem particularly in the normal confirmation work of the object. Absent.

When the object is copied for the purpose of forgery or the like, the display of the object and the display of the printing ink are doubled in the part of the object that overlaps with the part of the printing unit where the printing ink is attached. Therefore, the copy appears dark.

Further, when the display of the object does not overlap with the portion to which the printing ink adheres, only the density of the object is copied, so this non-overlapping portion is displayed in a light color.

Therefore, when an object such as a seal imprint or a sign covered with a cover sheet for preventing forgery is copied, a dark portion and a light portion are generated in one object, and it is clear that the object is a copy. It can be identified. It is almost impossible to modify this shaded part to be uniform, or it requires extremely advanced technology, so it is possible to prevent easy forgery.

The display method is not particularly limited as long as the print portion can show the light and shade on the object, and if the translucent print portion is formed narrower than the object, Areas that overlap the printed area appear dark, and areas that do not overlap appear light.

Further, if the semi-transparent print portion is formed by characters, figures, symbols, and patterns displayed in white, even if the print portion is wider than an object such as a seal imprint or a sign, white printing is performed. Since the part appears light and the background pattern appears dark, it is easy to see that it is a copy. In this case, it goes without saying that the printing portion can be formed narrower than the target object.

Further, the semi-transparent print portion may be formed by characters, figures, symbols, or patterns that are not displayed in white. The technical effect is almost the same as above. In addition, if it is formed of characters, figures, symbols, and patterns, it becomes possible to use the covering sheet for advertising and to enhance the taste.

In addition, if the translucent printing section is formed by displaying one straight line that is narrower than the target object, the printing section can be simplified, and when forming with characters, figures, symbols, patterns, etc. In comparison, the visual confirmation work of the object covered with the covering sheet becomes easier.

If the translucent printing section is formed by displaying a plurality of straight lines that are narrower than the target object, it will be covered in comparison with the case of forming characters, figures, symbols, patterns, etc. While facilitating visual confirmation of the object covered with the sheet, it is possible to increase the number of shades on the object and make correction difficult.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. (1) is a cover sheet, which is made of a transparent or translucent material such as tetron or polypropylene. In addition, it has a sufficient area to cover the surface of the object (3) for anti-counterfeiting purposes such as the stamped part and the sign part of the display (2) such as bankbook, securities, check, passport, etc. There is.

The transparent or semi-transparent cover sheet (1) has a pressure-sensitive adhesive layer (4) for fastening on the back surface as shown in FIG. The covering sheet (1) is releasably attached to a release liner or the like until use.

A printing unit (5) is provided on the front surface or the back surface of the covering sheet (1). The printing section (5) is semi-transparent so that at least a part of the object (3) such as a covered imprint and a sign can be seen through, and the object is covered with the covering sheet (1) as shown in FIG. It is assumed that (3) can be visually confirmed and that there will be no particular hindrance in the normal confirmation work of the object (3).

Further, as shown in FIG. 2, the semi-transparent printing part (5) is formed narrower than the object (3).

Then, in order to cover the object (3) for the purpose of preventing forgery such as a seal imprint and a sign with the covering sheet (1), the semi-transparent printing part (5) is overlapped with the object (3). To do. Due to the fixing of the covering sheet (1), a part of the object (3) overlaps the printing part (5), and another part does not overlap the printing part (5) and is transparent or translucent. Only the covering sheet (1) of 1 is covered.

Then, when this object (3) is copied for the purpose of forgery or the like, the part of the object (3) that overlaps the part of the printing unit (5) to which the printing ink is attached is the object (3). Since the display of and the display of the print ink doubly overlap, the copy appears dark as shown in FIG. If the display of the object (3) does not overlap with the part where the printing ink adheres, only the density of the object (3) is copied, so this non-overlapping part is displayed in a light color.

Therefore, when an object (3) such as a seal imprint or signature covered with the anti-counterfeiting covering sheet (1) is copied, a dark part and a light part are generated in one object (3), It is possible to clearly discriminate that it is a copy. It is almost impossible to modify this shaded part to be uniform, or it requires extremely high technology, so it is possible to prevent easy forgery.

In the above-described first embodiment, the semi-transparent print part (5) is formed to be narrower than the object (3), but the print part (5) is the object ( The display method is not particularly limited as long as the light and shade appear in 3).

Even if the object (3) such as a seal imprint or a sign is wider than the object (3), the white areas appear light and the ground pattern areas appear dark when copied, which makes it easy to identify the copy. In this case, of course, as shown in FIG. 4, the printing portion (5) can be formed narrower than the object (3).

In this embodiment, the shades appearing on the object (3) are more complicated than in the case of the first embodiment, as shown in FIG. 5, and it is possible to make the correction of the shade portion even more difficult. is there.

Further, the semi-transparent printing portion (5) may be represented by characters as shown in FIG. 7, or may be represented by a symbol such as a bar code as shown in FIG. It may be formed by the symbol or pattern. The technical effect is almost the same as the above, but if it is formed by letters, figures, symbols, and patterns, it becomes possible to use the covering sheet (1) for advertising and to enhance the hobby.

Further, as shown in FIG. 2, if the translucent printing part (5) is formed by displaying one straight line narrower than the object (3), the printing part (5) will be Compared to the case of simplifying and forming with characters, figures, symbols, patterns, etc., the visual confirmation work of the object (3) covered with the covering sheet (1) becomes easier.

If the translucent printing part (5) is formed by displaying a plurality of straight lines narrower than the object (3) as shown in FIG. 9, characters, figures, symbols, Compared with the case of forming with a pattern etc., while making it easier to visually confirm the object (3) covered with the covering sheet (1), the number of shades on the object (3) is increased and it is difficult to correct. Can be When the printing section (5) is displayed by a plurality of straight lines, a single ruled line or a thin line such as an underline may be used as shown in FIG. Further, the ruled lines and thin lines such as underlines may be formed in the horizontal direction as shown in FIG. 9, but may be formed in the vertical direction as shown in FIG. 10 in another different embodiment.
