 HP Helps U.S. Clamp Down on Counterfeiting

HP is talking about ways to print their printers from being used to counterfeit money.

" This technique would detect the characteristic color of frequently counterfeited documents ("banknote green"). Were a user to attempt to print a banknote using the exact green in the correct density for a bill, the printer could modulate the color somewhat to produce distinct, visible bands of color. The change in the color wouldn't be visible in other images that use lots of green (photos of trees, for example), but would be evident in bills."
