I'm trying to determine the expected behavior of Monaco Profiler (v4.8) in
regards to preserving the black channel in device link profiles. A post on
here from a few years back from Marc Levine of Monaco Systems mentioned...
"Because a link is
a more direct transform table, special functionality such as channel
preservation can be used. MonacoPROFILER has a "preserve black" option when
making link profiles that basically takes the black channel from the
original file and moves it to the destination. After that, it recomputes the
CMY to achieve proper color matching and tonality."
When converting an image from CMYK to CMYK using a DLP created in this way
with Profiler, the resulting image still contains CMYK in areas that were
originally K only however. What appears to happen is that 100% K transforms
to 100%K. However, as you move away from 100%K down the scale towards 0%K,
CMY inks gradually are introduced into K only elements. So a 90% K object
contains some hints of CMY, an 85% K object contains a little more CMY and
so on. The statement above would suggest that the whole range of K only
tones should transform to K only.
