The UltraChrome "drydown" advantage is due, to a significant degree, to the
light black ink, which reduces both the ink load and the color load in darker
areas. This is an improvement on the previous 6 color dye machines, but less
so over 7 color dyes in the 7600/9600 which have light black dye ink; and of
course this does not effect the 10k or 10.6k at all, as they don't use the
light black.
To see what UltraChrome-like inks without light K are like, you don't need a
10600UC, you can see a pretty good emulation of it in the desktop C82, which
has no light K and avoids using K for much, if any black generation
(depending on the media setting), so the dark areas get high ink loads, and
lots of shifting pigment, making for a long drydown, and temperamental
results.
