Digital BW, The Print

I really have to go with neutrality being in the eyes of the beholder.  The same
print can be called neutral, warm or cool by different people.
I was at the SF Photo show a couple of weeks ago, I was amazed at the 
variability of the silver prints I saw there.  They appeared to have tones from
greenish, to reddish, to warm, to cool.  I feel that my own vision has varied over
time and is much more sensitive now than before.

As far as the K7 inks, I think the most obvious benefit is the smoothness.  It's
extremely smooth -- no dots visible even with a high power loupe.  Dmax is
probably about the same as other inks.  The color tone is very even across the
density range.  It will vary slightly depending on the paper -- in fact since it
has no variable tone varying the paper is the only option.  It measures very
close to neutral.  The paper tone naturally has a big effect at the light end.
