cutting back on the medium density (50% - 33%) inks in favor of a low
density one.

So just to be clear that is for matte where the 50% and 30% HPPK inks are
cool and difficult to warm up.
So I use 100%, 18% Eboni,  + 100%, 20%,10%,5% HPPK. Where the 18% Eboni is
used to warm up the 3/4 tones.
Note that 100% HPPK = 50% Eboni in density.

But for Glossy I use HPPK 100, 50, 20, 10, 5% + GO. But HPPK shadows are
very susceptible to GO %.
More than 10% GO in the shadows and the dmax reduces. Too much GO and you
can see the ink patches have a white haze.
I use 5% GO from dmax to 50% density and then increase it to about 75% GO at
paper white.
