This profile can be imported in the characterization step by clicking the 3rd
party ICC button.
Note that a preview of measurement data will not be available for imported
profiles.
ICC Generation
In this final step, parameters for black generation, size and compensations
can be set before generating the icc profile.
Black
Generation
In theory, cyan, magenta and yellow mixed
together should produce black. In practice, mixing
CMY together produces a muddy dark gray or
brown. In addition, CMY black tends to over-
saturate the print medium, because it requires
coverage from all three inks.
The solution is to use the CMYK color model, which
adds a true black that replaces CMY. The CMYK
model reduces over-saturation, produces better
blacks, and requires less ink.
The GCR settings determine when and to what
extent CMY will be replaced by black (K). The
higher the GCR is set, the more CMY black is
replaced with K black.
UCR based
curves
Under color removal is a
process of eliminating
overlapping yellow, magenta,
and cyan that would have
added to a dark neutral (black)
and replacing them with black
ink only

curves
With Gray Component
Replacement CMY values that
add to grey all along the tone
scale can be replaced with
black ink.
(In contrast : UCR only adds
black to the CMY equivalent of
what would have printed as a
grey or near-grey)
