I usually hestitate to say something is impossible, but I've seen a fair
amount of combinations of UC inks on Ilford Smooth Pearl and Premium Glossy.
Everything from two blacks with toners, one black, only gray, black and gray
with no toners and various combinations of matte black and photo black. I've
never seen a result that to me was even remotely acceptable. If there exists
a way to combine UC inks in a grayscale curve to remove bronzing on these
papers I don't know what it would be.

What definitely works is PKN with Gloss Optimizer. That effectively removes
all bronzing, and looks particularly good on Ilford Smooth Pearl, with Epson
Premium Semigloss coming a close second. As an added bonus you get
incredible dmax.

Now MIS has inks with a new base that's supposed to eliminate the bronzing
without the need for GLOP. I'm waiting for my MIS PRO inkset now and will
probably post curves in the coming week.
