I agree, Wes. I am going to have to check out the Kodak double-sided
transparency material.  I used to do this by printing on two sheets of
transparency film and sandwiching them.  One advantage to this approach is
that pre-tests are not necessary for alignment.  I still think I Iike your
single-sheet approach better, however, as it can't be misaligned later.

Another thought, which I have not tried yet, but will if I get time (maybe
someone else would like to).  That is to print a pair of anaglyph viewing
glasses on transparency material.  Using the same inks for them as used to
print the anaglyphs should result in pretty good cross-cancellation, at
least theoretically (there are other factors, of course, such as color of
the viewing light source, etc.).
