Xerox Develops Printing Technology Invisible To Naked Eyes

Xerox has said that it will introduce a new, inexpensive printing technology to help thwart counterfeiters by making it invisible to naked eyes.

The new technology lets customers to print with variable text visible only under infrared light. The technology could be used to authenticate tickets, coupons, certificates, license and other identification papers that have been profitable to forge, Xerox said.

If a document with the special font is copied or altered, the text becomes distorted and illegible under infrared light.

The technology was co-developed by Raja Bala, a principal scientist in the Xerox’s Research Center in Webster. Xerox is pitching the new technology as useful in anti-counterfeiting efforts.

Xerox said, each of the four colour toners the company uses — cyan, magenta, yellow and black — react differently to infrared light, the company was able to come up with a combination only detectable under infrared.
