Just for clarification, aren't the Eboni black and the Ultratone
(Ultrachrome) VM black inks two separate inks/ink types?

Somebody correct me if I am wrong but I believe the Eboni is the new black
that replaces the black in all other ink systems EXCEPT the Ultratone VM
inks.  The two types of black offered as part of the Ultratone VM system are
different from Eboni and come in two separate formulas - one for matte and
one for gloss/semigloss.

There seems to be a lot of comments that don't make this distinction and it
is leading to some incorrect perceptions (some unfair) for the different
inks.
