Thanks, but the solution I'm looking for has to use inks.

I'm open to other things, but the mask needs to be a circle so a polygon 
is out, and backpattern won't work because of a bug/unsupported use (see 
the fine print in the Dictionary about the specific dimension 
requirements for backPattern, which turned out to be a problem for us).

So inks it is.  If it's possible now that the good inks are gone.
