If you ever tried to photocopy or edit money in Photoshop, you would have noticed that most modern scanners won’t allow you to copy, print or edit any type of bill, no matter the denomination. From personal experience, when i tried this a couple of years ago, even though my printer scanned the bill, i couldn’t open the scanned image in Photoshop.
But have you ever wondered how printers understand that the item you just loaded in the tray is not just paper but a banknote? Well, we know have the answer and as it turns out it all has to do with a hidden pattern called the Eurion Constellation, which can be found not only on US dollars, but on banknotes issued all over the world.
