Xerox adds fluorescence

Tech brief

GLOWING REFERENCES: Xerox scientist Reiner Eschbach demonstrates how an ultraviolet light can reveal hidden words and figures.

Why? To deter counterfeiting.

It's just like the embedded strip in U.S. currency larger than $10 that glows when you put it under ultraviolet light. The fluorescent printing is one of several specialty-imaging technologies Xerox has developed to make it easier for a suspicious recipient to tell which checks, certificates or other printed materials are authentic.

The new specialty font is part of the Xerox FreeFlow Variable Information Suite 5.0, software Xerox sells to commercial printers that produce personalized documents.
