Thanks for the suggestion. Unfortunately it is just this more
complicated situation I must deal with. For 2D graphics I am able to
produce grayscale versions of the color graphics. I am now left with
the 3D graphics. Some are produced by Plot3D[] and others by
RegionPlot3D[]. I have tried specifying ColorFunction->"GrayTones",
but the output seems too dark (too black, not enough gray). If you
have any further suggestions or can point me to some documentation or
examples, I would be grateful.

Thanks,
Bob
