Myself and a colleague were evaluating some custom RGB profiles a
couple of months ago and both agreed that Monaco PROFILER (v4.8.3)
was performing better than ProfileMaker (v5.0.8) in both smoothness
and maintaining color saturation (we did not test/measure for
accuracy however). The only caveat is that we only tested the
"Colorful" gamut mapping in PM5. When I get a chance, I'd like to
test the other gamut mapping options to see if there's an improvement.
I have also performed exhaustive testing and found the same to be true
for all three gamut mapping options. When comparing spot color
matching I have found MP profiles to match with less DeltaE variances.
I have repeated these tests on several inkjets, silver halide, and
CMYK signage machines.
One complaint with PMP's perceptual rendering (any of them) is that
the skin tones come out slightly too pink/magenta. Photolabs that are
highly sensitive and skilled working with skin tones pick up on this
quickly and love MP's perceptual rendering. When shown comparisons,
I've found 10 out of 10 photolabs also prefer MP's gray balance for
b&w printing in color.
MP's 2 step profiling is particularly useful with silver halide
machines that often suffer from inconsistent grey balance linearization.
My complaint with "LOGO Colorful" is that it introduces some contrast
and saturation boost to what I like to call mid-gamut colors. I prefer
not only MP's variable perceptual saturation control but, more
importantly, the behavior of the boost. MP does a better job boosting
edge-gamut saturation while leaving mid-gamut saturation levels alone.
The end result is natural looking skin tones and fantastic solid color
(like 255,0,0) saturation. When MP's perceptual saturation is set to
47 I feel it yields the best trade off between edge gamut saturation
with a minimal loss of detail. Fall color photographs are particularly
fun to look at when testing perceptual rendering intents. MP sat=47
profiles print these images with excellent saturation without loosing
much detail in the leaves. IMHO, MP's perceptual rendering is their
crown jewel that has largely gone unnoticed by the masses.
