Digital BW, The Print

Some have wondered why the "neutral" inksets tend to have dark inks that
have a less magenta or more greenish (which I try to avoid) bias than the
lighter inks.  My response has been that most papers tend to print more
magenta in the shadows.  This can be seen in the tones of the C88, which has
only one midtone ink density and tone.  See graph #4 in this PDF regarding
that inkset: http://home1.gte.net/res09aij/C88_EZ_CSR_SPECTRO.pdf

When the inkset is profiled to give an equal Lab B through the midtones, Lab
A rises as the densities increase, even though there are no cross-overs to a
different toned ink in the midtones.  Whether this is good or bad may be
subjective, but if one wants the Lab A & B curves to both be flat, the ratio
of cyan to R800 blue (or magenta) in the toned (blended) ink must increase
with increasing density.
