Sorry for not being clear. I didn't have a web address to give you at  
that time since it had not appeared on the web yet.  Here it is:

quoting http://www.gromacs.org/pipermail/gmx-users/2009-February/039765.html

a) representation volumeslice
b) graphics--> represenations --> change coloring method to "volume"
c) graphics-->colors-> color scales --> change to white/black
d) graphics-->colors-> color scales --> slide the offset and midpoint
until you see the level of detail that you want
e) render this and take it to gimp or photoshop, change the background
to transparent, false color the density that remains, and overlay it on
a white background or perhaps overlay it on an exactly scaled picture of
one representative conformation (you can do this exactly by loading in
the correct structure along with the .cuge file to vmd and changing the
representation to output two separate files at exactly the same
scaling/rotating).

Chris.
