Description

[Detailed explanation of the invention] This invention is for stamping (printing) documents such as passbooks and certificates.
Forgery of seals or signatures affixed to columns or signature columns;
Concerning forms that are designed to prevent falsification.

At banks, etc., when a passbook is issued, the customer registers the seal by stamping the customer's seal in the delivery seal column on the back of the passbook at the counter, and when withdrawing money,
Identity verification is performed by comparing the stamp on the passbook and the stamp stamped on the deposit refund request slip submitted by the withdrawer. but,
If your passbook is stolen, there is a risk that someone else may tamper with the delivery seal column and affix a different seal to easily withdraw your deposits.

For this reason, conventional bank passbooks have a seal made of a transparent plastic film with a thickness of 20 to 50 μm in the delivery stamp column after the stamp is affixed to prevent staining and protection of the stamp impression, as well as to prevent falsification and counterfeiting as described above. is being pasted.
Furthermore, in order to prevent plastic films from being replaced, plastic films with a light transparent color or background pattern are used, or small cuts are made around these plastic films.

On the other hand, since passbooks are subjected to mechanical processing such as writing, etc., it is inevitable that the endpapers have a strong surface strength. Therefore, it is possible to cleanly peel off the above seal using a cutter knife, etc. Therefore, after peeling off the seal, it is possible to tamper with it by scraping off the seal imprint on the delivery stamp field and affixing another seal, and then apply the above seal again. It was not impossible to reattach it.

This invention was made in view of the above circumstances, and the purpose is to provide a form that can prevent forgery or falsification of seals, signatures, etc. affixed to the seal area or signature area of forms such as bankbooks and certificates. shall be. In other words, the present invention provides a form having a seal area or a signature area, in which a background pattern or fine pattern is printed on the base forming the seal area or the signature area, and a A transparent or nearly transparent release layer and a white or nearly white porous layer with good ink absorption properties are laminated in this order through the pattern, and the hue of the pattern on the seal area or signature area is , the brightness and chroma are adjusted so that only when observed through the release layer and the porous layer, the pattern appears almost equal to that of the pattern printed outside the seal area or signature area. The purpose is to provide reports that

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments.

FIG. 1A shows an embodiment of the present invention.
is a base body provided with a stamp field or a signature field for bankbooks and certificates, and patterns 2 and 3 such as background patterns and fine patterns are printed on the top of the base body. A transparent or almost transparent release layer 4 is provided on the top surface of the seal area or signature area through the pattern 3.
and a white or nearly white porous layer 5 with good ink adhesion are laminated in this order. This release layer 4 is made of varnish (for example, PB-80-OP varnish, manufactured by Toyo Ink).
Co., Ltd.), a material (coating agent or ink) with good releasability such as wax (paraffin wax, etc.) is printed on the substrate 1 by gravure printing, silk screen printing, etc., for example, several μm or several + μm.
It is formed to a thickness of .

In addition, the porous layer 5 is applied with ink (i.e., seal ink such as vermilion ink, sign ink, type ribbon ink, etc.) by printing or foil stamping in such a manner that it overlaps with this release layer 4. Made of highly absorbent material. Specifically, a pigment foil or ink containing oil-absorbing and water-absorbing extender pigments such as calcium carbonate, calcium sulfate, aluminum white, and calcium silicate is used, and the release layer 4
For example, it is formed on the top with a thickness of several μm or several + μm.

Furthermore, characters or patterns may be attached to the upper surface and/or lower surface of the porous layer 5 for the purpose of preventing forgery and tampering.

In the present invention, the configuration of the stamp field or signature field in the form is as described above, and the hue, brightness and saturation of the pattern 3 in the stamp field or signature field are controlled through the release layer 4 and the porous layer 5. The hue, brightness, and saturation of the patterns 2 and 3 and the opacity of the release layer 4 are such that the hue, brightness, and saturation of the patterns 2 and 3 and the opacity of the release layer 4 appear to be almost the same as the hue, brightness, and saturation of the pattern 2 printed in areas other than the seal area or signature area only when observed. It is necessary to adjust the transparency of the porous layer 5 (see Figure 2A, for example, use magenta ink to adjust the solid density of the pattern 3 to 0.25~
The solid density of pattern 2 was set to about 0.3 and the solid density of pattern 2 was set to about 0.1 to 0.5. When porous layer 5 is printed using ink blended at a ratio of about 6:4 or 7:3 while adjusting its thickness, the hue, brightness, and saturation of pattern 3 and pattern 2 will appear to be equal. (The amount of porous layer 5 is approximately 10
~25 μm).

If a seal or signature is affixed to the seal field or signature field with such a configuration, ink is permeated into the porous layer 5 (8 is the ink permeation part), and the entire surface is then covered with the seal 6, it is impossible for someone else to forge or tamper with it. for seal 6
When it is peeled off, the entire porous layer 5 is peeled off from the peeling layer 4 together with the seal 6 as shown in FIG. 1B. Therefore, no porous layer 5 remains on the base 1, making it difficult to tamper with the seal impression or signature. Further, regarding the seal 6, it is difficult to cleanly remove the attached ink-impregnated porous layer 5 from the seal 6, making it extremely difficult to reuse it. Also,
In order to further ensure that the seal 6 is not reused, small cuts may be made around the seal 6, such as those provided around the price sticker or on a part of the seal of a synthetic resin packaging bag. .

Furthermore, in the present invention, the characteristics of the release layer 4, the porous layer 5, and the patterns 2 and 3 are adjusted as described above, so that the patterns 2 and 3 cannot be distinguished in the state shown in FIG. 1A. (see Figure 2A),
When the sticker 6 is peeled off and the patterns 3 are observed through the peeling layer 4 as shown in FIG. 2B, each pattern appears to have completely different saturation and lightness.
The two can be distinguished. Such a change would surprise and deter would-be counterfeiters and falsifiers. Even if a seal or signature is forged or tampered with by forming something that looks like a porous layer on the exposed release layer 4 using white obscuring ink, which is often used for character correction these days, It is very difficult to adjust the whiteness and opacity to the characteristics described above, and if you closely observe the condition of the pattern 3 and the surrounding pattern 2 in the resealed seal or signature area, you will be able to see the results. It will become clear that some kind of work has been done there.

On the other hand, FIG. 3 shows a modification corresponding to the embodiment shown in FIG. 1, and the difference from the example shown in FIG. 1 is that the porous layer 5 is formed wider than the release layer 4. The rest of the configuration is the same as that in FIG. 1, so the explanation thereof will be omitted. In this case, when the seal 6 is peeled off, the porous layer 5 in the part adhering to the base 1 undergoes interlayer separation from the middle, and the porous layer 5 in the part adhering to the peeling layer 4 becomes as shown in FIG. 1B. The whole thing is peeled off as shown. Not only is it difficult to falsify or forge for the same reason as in the above embodiment, but if characters and tints are added to the porous layer 5 in advance, the characters and tints on the release layer 4 and the base 1 are Since the characters and background pattern are interrupted, even if someone tries to stamp a different seal by applying some processing to the release layer, the characters and background pattern are interrupted, making it impossible to tamper with or forge.

As detailed above, according to this invention, since the seal, signature, etc. are performed through a porous layer that has good permeability to ink, it is effective to prevent falsification or forgery of the stamp field or signature field of the form. can be prevented.
