Steven, the attempted solution doesn't meed the desired end anyway. I
think there is a difference between mixing color pigs in with the
carbon directly in the solution, and mixing it in via dots with an
additional head. There is an image structure difference, and I suspect
a longevity difference and metamerism difference, but there has been
little discussion of those differences and they haven't really been
explored in depth.

Based on your post I think you favor the "mixed in" approach, but to
be clear, you actually are utilizing a color component.

One note of interest. Much to Bill Bergh's dismay, the IJM's Carbon
Sepia inkset, which he designed as supposedly pure carbon, fell
slightly short of the other sets that do have color pigs mixed into
them for hue, in their RIT tests. There seemed to be some positive
symbiotic effect on longevity.
Clearly there is more going on with mixing inks than some of us might
think at a glance...
