In specialized cases, editing can help a great deal. The only editor
I know which allows you to do this is the Kodak editor.
Use the Photodisk target and focus on the robot. Use selective color
(absolute) to add three percent each cyan and black to the reds.
Measure with the eyedropper - not the selective color slider. This
will give you dirtier and apparently deeper reds.
This may not be an ideal general purpose profile, but if you need
Alabama red it's a great trick. Sometimes it is more important to hit
a memory color than to achieve maximum gamut. I have several profiles
developed for specific teams, and assign them by subject. It is also
useful if you are reproducing original artwork with rich pigments and
a scattered gamut.
You can achieve similar results with navy blue, deep ochre and forest
green. The gold in the Photodisk label is another standard color that
is hard to hit without this edit.
If you look at the old color tables developed by Dr. Hell, which were
calibrated on human perception instead of spectral data, this kind of
dirty separation is common. My guess is that it related to the way
humans shift from cone to rod perception for darker colors.
