Yes, I think the Ink limit being higher than it need to be will create
darker mid tones. Most other curves I've seen have a greater gap between the
K limit and Black Boost. I just looked at a half dozen curves and they're
all in the 15-30% range. Dropping K limit might remove that little crinkle
at the end of your curve and remove the need to make arbitrary changes to
values. So would adjusting the gray curve gamma up a bit.
