The UT-2200, which appears to have been re-named "UT7" on the MIS webpage
(signaling that it is for all 7-ink Epsons), is a re-mixed UT2.  The 2200
(and other UltraChrome printers) put such a different ratio of cyan and
magenta in the "neutral" shades that the cool toner needed to be changed not
only in its mix but also in its position.  

The dmax, archival, light fastness, and printing characteristics of the
inksets are the same.  The "light black" has almost no impact on the image,
with the exception of a grayscale image printed with no curves and no slider
adjustments.  There the light black (which I decided not to tone more
neutral) causes a slight increase in the warmth of the shadows.
