MaxK / MuchK
These curves try to use as much
K as possible and only at high
saturation levels CMY
components are added to
create a higher density black.
MinK
This curve uses as little of the K
ink as possible. CMY
components are used to make
up the grays for as long as
possible and only at higher
saturation levels K is added to
create a higher density black.
This determines at which percentage of gray the
black (K) channel begins to replace CMY.
A low Black Width value only generates black in the
neutral areas. High values also generate black in
the colorful shadows.
This is a sum of the ink limit values for all process inks
combined.
Size of the LUTs (Lookup Tables) in the profile. The
size has an impact on the precision of the profile
and its calculation time. It has no impact on the
processing time using the profile.
Even though v4 has been in the market for a while,
a lot of input profiles are still v2.1. The rule with icc
version is that it is best to have the same version
across your work flow. If your input profiles are 2.1,
choose 2.1 for the output profiles.
Some media have a coating applied to make
them look whiter - this is very common with fabrics.
This coating is called an Optical Brightener. Optical,
because the coating is actually a very light blue
but our human eyes pick up on this color as white.
Measurement devices, however, see the blue for
what it is.
This option compensates for the difference
between what the measurement device and the
human eye perceive.
