There are Japanese technologies in the manufacturing process of RMB.

The People's Bank of China tried Omron ring anti-counterfeiting technology on the 1999 RMB 1 yuan banknotes issued in 2004, and the anti-copying effect was good. In the fifth set of RMB banknotes with different denominations in the 2005 edition, this technology was completely adopted.

This technology was invented by Omron Corporation of Japan and obtained U.S. patent 5,845,008. This design is adopted by the world's major currencies such as US dollar, Euro, Japanese yen and RMB.

Omron ring, also known as round constellation anti-counterfeiting technology, is a kind of currency anti-counterfeiting technology. Anti-counterfeiting technology of round constellation EURion constellation is usually called anti-copy circle. This anti-counterfeiting technology consists of five small circles arranged in the form of Orion constellation to form a complete constellation pattern.

Technical principle of Omron ring;

EURion constellation is a secret graphic symbol rule created by 1996. This rule is recognized by many image processing software and printers, and the things that use this symbol rule cannot be printed and copied by these graphics software and printers. Once the pattern containing this constellation is found, the copier will automatically process the output, which will cause serious color distortion in the output.

The program of judging EURion constellation by Photoshop is completed by the anti-counterfeiting system developed by the central bank's banknote inspection group-banknote inspection system. CDS aims to prevent the use of personal computers, digital imaging equipment and software to make counterfeit money.
