Digital BW, The Print

Paul,

For what it is worth, I ordered fresh bottles of Eboni in the various tones to 
provide a fresh baseline. Inksupply does state the base can be used to 
"dilute MIS Epson type inks to make lighter inks". The title suggests it can be 
used on Eboni but also used for cleaning. So once I get the new inks I will mix 
a batch of Eboni tones and compare. I trust you are correct in the fact that 
generic base will print smoother than the MIS stock base. If nothig else, the 
stock base will come in handy as a cleaning solution for my R2400 & 2200 
printers. For as little as I use in a year I just dont see the effeciency of 
mixing my own generic base.

CLEAR BASE STOCK FOR ALL MIS INKS INCLUDING ULTRATONE - 4 OZ BOTTLE 

Thanks for the help.

Phil

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.

It is for matte paper only. 

> How does this difference if any affect final print tone?

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.

> Impact on the printer??

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.
