The RMB manufacturing process contains Japanese technology.
The People's Bank of my country tried Omron ring anti-counterfeiting technology on the 1999 version of the 1-yuan banknote issued in 2004, and the anti-copying effect was good. This technology is fully adopted in the fifth set of RMB banknotes of all denominations in the 2005 edition.
This technology was invented by Japan's Omron Corporation and obtained U.S. Patent 5,845,008. The world's major currencies, such as the US dollar, euro, Japanese yen, RMB, etc., all use this design.
Omron ring, also known as circle constellation anti-counterfeiting technology, is an anti-counterfeiting technology for currency. Circle constellation anti-counterfeiting technology EURion constellation is what people often call anti-copying circles. This anti-counterfeiting technology consists of 5 small circles arranged in the form of the Orion constellation to form a complete constellation pattern.
Extended information:
Omron ring technology principle:
EURion constellation is a secret graphic symbol rule created in 1996. This kind of rule is recognized and recognized by many image processing software and printers. Things that use this symbol rule cannot be printed and copied by these graphics software and printers. Once such a constellation pattern is found, the copier will automatically perform output processing, causing serious color distortion in the output product.
The procedure for Photoshop to determine the EURion constellation is completed by the Counterfeit Deterrence System, an anti-counterfeiting system developed by the Central Bank Counterfeit Deterrence Group. CDS aims to prevent the use of personal computers, digital imaging equipment and software to create counterfeit banknotes.
