Digital BW, The Print

The story continues ... I orginally purchased the non E version of
the MIS FS Hex inks and this started me on a project to measure the
relative ink densities ( while waiting for the E versions to arrive )

If I create a CMY color pattern and extract the Luminance, I obtain
C = 30 %
M = 59 %
Y = 12 %

Even if there is a non linear relationship between the ink densities 
and printed color, this inkset seems 'strange'

The relative grey densities commpared to the Black are :

B = 100 %
C = 26 %
M = 7.2 %
Y = 3.2 %
PCe = 9.6 %
PMe = 1.6 %

I am sure there is some factor that I am missing, And that may be the
EpsonDriver in the way it is attempting to create grey shades from
its presumed hex color set, but I would have thought that M should
have been the darkest ink and that the C and M photo inks perhaps
2/3rds or half the density of their full depth ink. The PMe is much
lighter than Yellow....

I just don't wish to fill the carts and then have another problem
with posterized prints as I did the last time with VM on my 2000P.

Thanks,

This is getting challenging ...
