I have a question about the knockout function of Publisher 2003.  I am
working on a job that is 3 spot colors and want the printed piece to allow
the black text to overprint on a screened spot color box.  Everything that I
have tried has resulted in the spot box being knocked out.  I have verified
the settings for black text to overprint, for black to overprint at 100%, and
I have designated by object and by text to allow for overprint.  Each of
these setting has had no effect on the resulting output.  All objects in
question were created in Publisher.

I am doing a Save As to a Postscript file as a CMYK comp using Press Quality
settings with  Acrobat Distiller 7.0.1 as my postscript printer.  I do have a
rather lengthy work around that will accomplish what I want, but I'm curious
if I'm missing something.  It would save me a great deal of time in the
future if this preference would work as it seems to be intended to.  

This is a client's file that probably came from Publisher 2000 or earlier so
I don't know if that would make this happen or not.  I did save a new version
of the file from Pub 2003, so I'm thinking that this wouldn't be a cause.

Any response would be appreciated.
