In the 70's I worked for Electro-Optical Systems in Pasadena, a Xerox holding.
Our group (electronic printing and publishing) worked with a satellite PARC lab
on-site which had demonstrated the first color hardcopy ala digital xerography.

Not long after, the FBI appeared and "challenged" our resident color expert to
do his darnest in counterfeiting US currency. "We supply the specimens and raw
stock, you supply the know-how." On leaving, *every* scrap of paper, printed or
otherwise, went with them. Their aim was to track emerging print technologies.

Although they didn't say much (like in the movies) our expert can now include
"considered by the FBI one of the US's better counterfeiters" on his vitae.
