Subject: Re: Building profiles

A CMM uses ICC profiles to remap input color to the nearest printable
color the device/paper/ink can manage.
Quadtone profiles require density remapping for propper gradation, but
also assigning different tonal areas of the input to their apropriate
quad ink. This assumes a standard color driver without this
partitioning capability built in. The ICC approach and profiling
software has no way of knowing you want to send all your highlights to
a light gray ink that happens to reside in the yellow ink tank, then
smoothly transition to a darker ink that happpens to reside in the
magenta tank, etc...
This isn't to say you coudn't profile it, and even print through your
profile with possibly some success, but there will be no ink
partitioning to take advantage of using a quad inkset.
Color management, with the use of a profile, simply remaps color from
one defined space to another as closely as possible given the
characteristics of the two spaces.
Hope that makes sense.
