Printer Constellation _ Star Printer

"Orion" is probably a secret graphic symbol rule created by 1996. This rule is recognized by many graphics software and printers, and the things that use this symbol rule cannot be printed and copied by these graphics software and printers.

Photoshop's program for judging "EURion constellation" is completed by the counterfeit currency detection system (CDS), an anti-counterfeiting system developed by the counterfeit currency detection group of the Central Bank. CDS aims to prevent the use of personal computers, digital imaging equipment and software to make counterfeit money. It can prevent personal computers and digital imaging tools from acquiring or copying protected banknote images. Many color printers will produce serious color distortion when they see "Auri constellation".

EURion constellation, also known as round constellation anti-counterfeiting technology, is what people often say about anti-duplication circle. This anti-counterfeiting technology consists of five small circles arranged in the form of Orion constellation to form a complete constellation pattern. In the production of color copiers, the recognition of this pattern is preset. Once this constellation pattern is found, the copier will automatically output it, resulting in serious color distortion.

The People's Bank of China tried this technology on the 1999 RMB 1 yuan banknotes issued in 2004, and the anti-copying effect was good. In the updated version in 2005, this technology was completely adopted.
