> What's a quick way to invert output for exposing photoresist?

Select the "ps-invert" option in the dialog.  There's also a "mirror"
option if you need it flipped over (the ink should be towards the
board for the best focus).

However, I use png export for masks as some postscript interpreters
make objects one pixel too big or too small due to edge condition
rules in PS.
