偽判別方法に関する。The present invention is used for banknotes, securities, stock certificates, pass tickets such as tickets and commuter passes, coupons on toll roads, passports, income stamps, various tickets, and other securities. It is impossible for a third party to identify that a magnetic pattern of security pattern is visually given an arbitrary pattern of magnetism, and by using an arbitrary magnetic property detection device, it is magnetically authentic. TECHNICAL FIELD The present invention relates to a magnetic information recorded printed matter excellent in security and a method of determining the authenticity thereof.

別方法の向上を図ることが一般的に行われている。2. Description of the Related Art Banknotes, stock certificates, and other securities have a monetary value, and therefore, in order to guarantee and maintain the value, it is necessary to apply forgery and tampering prevention techniques.
Therefore, by forming a specific magnetic pattern such as a bar code on such a printed material with magnetic ink,
It is common practice to improve the effect of preventing forgery and tampering, and to improve the method of determining authenticity by mechanical processing.

いる。Recently, in order to further improve the security of such printed matter, in order to prevent a third party from visually recognizing the magnetic pattern applied to the printed matter, the magnetic pattern is changed to a dark-dark color system. There is a method of providing a concealing layer that completely conceals with a concealing layer, or using a dummy pattern of the same color as the magnetic pattern.

る。However, in a magnetic information recording printed matter to which a magnetic pattern is simply added or a magnetic information recording printed matter in which the magnetic pattern is made invisible to a third party, it is used for forming the magnetic pattern. Typical examples of the magnetic material powder to be used include γ-Fe2O3, Fe3O4, Co-containing iron oxide, CrO2, metal powder, and Ba ferrite. These powders have strong absorption in the visible light range, and the magnetic powder exhibits black, black-gray or brownish brown, so that the magnetic pattern can be mechanically processed to some extent by S / N.
If an attempt is made to have a magnetic intensity having a specific ratio, the magnetic pattern itself presents a dark dark color system such as black, black gray or brown. Therefore, in order to make the magnetic pattern invisible, it is necessary to use a darker concealment layer or a darker dummy pattern similar to the magnetic pattern than the magnetic pattern,
The magnetic pattern printed part of the final product is a dark color pattern, and third parties generally guess the magnetic judgment location from the color information and use genuinely distributed magnetic materials, It is possible to provide magnetic characteristics similar to those described above, and it is considered that the suppression effect is small as forgery prevention.

Even if a forgery is attempted by using various image processing and extraction techniques using a scanner or the like, it is impossible to faithfully reproduce the original, and furthermore, by using a generally distributed magnetic material, It was necessary to make it impossible to provide magnetic properties similar to the real ones.

This had a major impact on the design and image of the final product. However, the magnetic pattern of the magnetic information recording printed matter obtained by the means of the present embodiment can be camouflaged even with an object having a small concealment ratio such as a color pattern, and the new magnetic information having a very small effect on the design and image is obtained. It becomes possible to make a record printed matter.

刷物である。That is, the magnetic recording information printed matter obtained by the present invention has a magnetic pattern of a color similar to the color of the support paper on a white or light-colored support paper, and at least a part of the magnetic pattern overlaps the upper layer of the magnetic pattern. This makes it difficult to visually recognize the magnetic pattern without using a concealing layer that covers the magnetic pattern 100% in magnetic information recording and printing including a colored pattern that makes the magnetic pattern invisible. A magnetic information recording printed matter characterized by having a color pattern used in ordinary securities etc. printed in an arbitrary color on the magnetic pattern, thereby obtaining a magnetic material used for mechanical processing. It makes it very difficult for a third party to guess the printing position of the pattern, and it is necessary to camouflage the magnetic pattern. The printed pattern does not need to be completely concealed by dark, dark-colored inks such as black, black-gray or brownish-brown, and it is not necessary to use a dummy pattern by dark-darkened ink of the same color as the magnetic pattern, The feature is that camouflage can be performed with printed patterns that are in harmony with the overall product design and image. Also, if a third party is supposed that a magnetic pattern is printed there, and various image processing and extracting means are used by a computer and a scanner to extract the magnetic pattern for the purpose of forgery, the upper layer is not obtained. Due to the colored pattern, it is difficult to easily and faithfully reproduce and extract the separated magnetic pattern like the original due to the complicated pattern of the colored pattern.
Furthermore, the effect can be further improved by making the shape of the magnetic pattern a complicated pattern. That is, the magnetic information recording printed matter in the present invention, compared with the conventional printed matter concealing the magnetic pattern, a third party,
It is difficult to give magnetic properties similar to genuine products by using generally available magnetic materials by roughly guessing the magnetic judgment place, and manufacturing counterfeit tickets that are faithful to genuine notes Is a new magnetic information recording printed matter that makes it very difficult.
