Carbon is our most stable pigment, and Eboni is the most neutral carbon.  That is what Eboni-6 is for.  It is for matte paper only.

Those are the Eboni-6 and Carbon-6 densities.

That is what Eb4+ is about.

I have clarified the first page of the UT14 PDF a bit regarding the inks.

Eboni is denser than PK on matte paper.  So, PK can be the most dense midtone/gray ink and work fine with Eboni on matte paper.  On glossy paper the UT14 M and C are used to print the 100% black values.

Yes.  MIS ESC-Base-UC is best for cleaning (better yet if diluted 50% with distilled water).

MIS Glop (gloss optimizer) is the base for the MIS glossy inks.  It can also dilute HP PK to make nice gray inks that do not bronze as much as the HP grays.

The generic base is one you mix yourself.

Glop prints a bit warmer and ESC-Base-UC prints roughly when used to dilute Eboni.  The generic base prints much the same as the base MIS uses to make Eboni-6.  As far as I know, MIS does not sell the Eboni-6 base.

The generic base and Eboni-6 clog less than the glossy bases.  Inks that are glossy compatible need to have something that'll stick the pigs onto the paper.  They also stick onto the heads.

It will not print as smoothly as the generic base or Eboni-6.

Good luck with the system.
