User as much black as you can (lots of GCR and start the black as

as you can, especially light magenta, assuming you have control of
the light-dark ink transition. With ORIS Color Tuner, you might not
have control over either of these issues.

I've been able to completely eliminate both gloss

By combining the above two suggestions, the gloss differential problem
I've been seeing is almost completely eliminated. Thanks to everyone
who wrote in, I learned a lot.
First I learned that my problem is gloss differential, NOT bronzing.
There was just a specific area around the quarter tones that was way
shinier than the rest of the proof. When looked at obliquely, that
gloss does take on a bronze cast, so that's why I though it was
bronzing. I also learned that ORIS Colortuner does have some control
of GCR & black separation, but I can't control the individual inks,
which is unfortunate. Even with max GCR/CMY reduction Colortuner still
wants to put lots of CMY into neutrals, even when the input is pure
black. This may be the only way it can hit the GRACoL_coated1 target,
but the Ultrachrome K3 Photo black is supposed to reduce gloss
differential and I don't think very much of it gets used in the
problem areas.
By adjusting to max GCR I was able to reduce the gloss differential
about 30-40% and then spraying on Priemier Art Printshield got rid of
the rest. I'd rather not use a messy and somewhat toxic spray if I can
avoid it, so I'm fishing for additional suggestions. Anyone?
