Hi,

How do you set up the postscript device? What are you using to view the
postscript (GhostView?), which version? Some versions of Ghostview have
problems anti-aliasing properly. Does the problem occur in the printed
copy?

Example of other people getting this problem..

If it is Ghostview, there's an option to turn off anti-aliasing, see if
that helps.

Chris.
