These small circles are called Omron rings, which is the anti-counterfeiting technology of circle constellations. What is the recognition principle of this pattern is still a mystery. Omron ring is a pattern to prevent high-precision color copier, which is made up of five small circles arranged in the form of Orion. At present, this pattern recognition is preset in most copiers. Once this pattern is found, the copier will distort the output color or not directly output it.
Because Omron Ring has a very good effect of preventing counterfeit banknotes through color photocopiers, this technology has been adopted by major currencies in the world. Although there are so many rings on the banknote, there are not many Omron rings, usually only one, and the rest are obstacles made to disguise the Omron ring pattern.
