Forwarded for a friend:

A friend needs to submit a paper with the footnotes printed in
non-reproducing blue, i.e. that color that won't appear if you run it
through a copier. Does anyone know if you can print in that color from a
standard word processing program, and if so, which color blue exactly is
> it?

There is no colour that can be printed that cannot be reproduced using a copier. This was the problem where counterfeit copies were being made with (Canon) copiers. Copiers were 'corrected' such that certain colours reproduced badly producing unfaithful copies of certain currencies.

The trick to making something non-reproducible is to create a test chart of a wide gamut of hues, print it, and photocopy the test chart varying the controls of the copier to find which colour is reproduced most unreadable with a given copier setting. When making printouts, use the colour for the footnotes that reproduced the worst. If your gods are happy, you won't be able to read them. (With photocopiers shoot for light green - with photomultipliers, shoot for light red - with orthochromatic photographic film, shoot for light blue. These photosensitive materials have reduced sensitivity in these hues. HTH,

Why not print the foot-notes upside-down or small at the end of the publication? I can't fathom why footnotes should or would be designed to be unreadable.
