September 15, 2006 Xerox Corporation scientists have developed a digital printing font so tiny that you need a magnifying glass to read it. The new MicroText Specialty Imaging Font, just 1/100th of an inch high, is designed to help make valuable documents with personal information such as birth certificates, personal identification papers, and checks even harder to forge. Microscopic words are already hidden in the design of credit cards, checks and currency as a deterrent to counterfeiting. For instance, the "dots" in the border next to Andrew Jackson's right shoulder on current US$20 bills are really the tiny words "The United States of America 20 USA 20 USA." Now Xerox's innovation carries microprinting to the next level because it can make important documents more secure by individualizing the tiny letters and numbers.
