上記黒バーは顔料等の付着部（印刷部）であり、白バー
は黒バー間の非印刷部のことである。The above-mentioned identification marks on printed matter are recorded with numerical information representing codes and symbols such as monetary amounts and product numbers, as well as character information representing names, addresses, product names, etc., and are detected on the screen by optical means. , it is possible to read 8
For example, barcodes are composed of so-called black bars and white bars, and can express a large number of numbers and characters depending on the width of each black bar and white bar and how they are arranged, and can record various information. When the width of each bar is detected by optical means, recorded information consisting of numbers and letters can be read out. still,
The above-mentioned black bars are the areas to which pigments are attached (printed areas), and the white bars are the non-printed areas between the black bars.

ことが多い。Conventionally, such identification marks have been made of substances that absorb visible light, and therefore can be recognized with the naked eye. easily visible. However, as in the case of barcodes, it is often impossible to read the specific contents of the recorded information with the naked eye, and therefore the information has a relatively high degree of confidentiality. Therefore, such identification marks are often used when it is necessary to record or read out specific information or confidential information to identify the person transmitting the information and the person receiving the information.
（発明が解決しようとする課題）
ところが、上記従来の識別マーク付き印刷物においては

いう問題点がある。更には、目視可能な識別マークの存
在により、美観が損なわれたり、識別マーク以外の印刷
のスペースが減少したりするという欠点もある。(Problem to be Solved by the Invention) However, in the above-mentioned conventional printed matter with an identification mark, the identification mark can be visually perceived and its existence easily recognized, so the identification mark may be read illegally for the purpose of fraud etc. In addition to the problem that it lacks security because it can be copied, forged, altered, falsified, or altered, it also has the problem of being intentionally damaged or cut up, resulting in a complete loss of information. be. Furthermore, the presence of the visible identification mark has the disadvantage that the aesthetic appearance is impaired and the space for printing other than the identification mark is reduced.
かかる欠点をある程度改善する技術として、識別マーク
を磁気インキにより印刷し、その上に隠蔽性を有するイ
ンキにより印刷する方法がある。As a technique for overcoming these drawbacks to some extent, there is a method of printing an identification mark using magnetic ink and then printing on the identification mark using ink that has concealment properties.
