additionally, the only published 3rd party tests we've seen in recent
years bears this out.
All of Cone's Piezotone inksets and ink positions outperformed each
and every ink/position of the Epson UCK2s. Unfortunately we have no
comparative independent tests of the newer Cone sets, other mono ink
sets, or UCK3 comparisons, Canon or HP.
Nonetheless it's useful to note that not only did these purportedly
inferior "blended" ink sets leave the color inks in the dust, the
UCK2s faded at such unequal rates that any neutral build from them
would change color far faster than what might be considered
unacceptable density change.
Also, all of the Piezotone sets with (we assume) color pigment added
to adjust hue outperformed the "pure" carbon set.

Thankfully, there are more and more out of the box solutions for
enthusiasts who want to be able to print all photography from the same
printer, easily. Certainly there is a need for that for all kinds of
reasons, and the prints will probably have reasonable longevity.

While that front evolves, the state of the art for those whose
concerns are for primarily for uncompromising monochromatic
photographic printing and all it traditionally entails continues to
also evolve, and remains far out in front in addressing those concerns.
