Have you tried experimenting with paper colour instead? I used to work
part-time as the recording secretary for a board of directors; any
confidential minutes/materials were printed directly onto dark purple paper.
It was readable, but not photocopiable.
Waaaay back in the early 80s I also remember seeing some software
documentation printed on orange paper, possibly for the same reason (it
certainly wasn't to make it easy on the eyes!).
Take care,
Scott
