This is a very insightful reply and really nicely spells out the pitfalls of where I was headed with the Eboni 6 VT + 3MK. As I want to produce neutral prints as the first objective, the warning about the probable too warm output comes at just the right time as I haven't committed to the first set up runs. I'll now set up with the standard Eb6, with the 2 MK's and the toner substituting for the 3rd MK. As for the microbanding with the 1.5pl droplet, I ran across that unpleasant output on some negatives that where banding making them useless.There was some remedy from a technique suggested by Roy Harrington in 2005 to print at 2880dpi and adjust the Ink Limit Adjust to ~ -30. I dropped the boost K and upped the ink values a tad and all that seemed to help as the microbanding disappeared. But I never went on and printed out a variety of images to see how those were affected by the technique.
So for this initial set up, it'll be EB6 + MK + Toner and see how it turns out. Lastly, is the toner the Canon Lucia referenced in your EB6 + R1800 paper or is there a compatible alternate blue toner ink that will work as well?
So thanks as always for the insight and encouragement.

It'll be warm. My going to
a toner, in part, reflected the fact that I was not happy
with the way Eboni v.1.1 printed on inkjet paper. Arches
is still able to make a 100% carbon print that is within
what I believe people see as "neutral." Most
coated inkjet paper is no longer there; thus the
toner.

If you are proficient in QTR, then
you can put inks in almost any position. You'll also
be able to put the toner in one of the spots that has MK
in it.
I was not a huge fan of the 3MK
approach. It was something that many liked because it
allowed them to have color printing with matte paper as well
as 100% carbon printing that was almost dead neutral. MK,
not diluted, is still very neutral. The 3 positions were
needed to hide microbanding.
What I'd probably end up doing
with such a printer now is have only 2 MK positions --
needed for best Arches printing as well as useful for making
dilute Eb6 100% carbon prints more neutral by having one of
the MK inks be a "Black Only" type ink, but used
more as a "toner" to pull the warmer dilute ink
image toward neutral. Note that while 2 MKs were needed to
hide microbanding when MK was the only ink, where the full
Eb6 inks are also in the mix, a single MK is going to be a
smoother way to pull the 100% carbon image toward neutral
than using the full 3MK profiles in conjunction with an Eb6
profile. As such, I'd put the toner where the third MK
would be. I'd use only QTR to print.
This is all easy to do piecemeal.
An Eb6 plus 3MK setup allows you to see how each approach
works. If you want more neutrality, the toner can be
easily added later.

Paul,
Thanks as always for your time on an answer for a well
running but older system. I'll set the R1800 up the
following way, putting in the original idea of the 2%
instead of a toner at Y, and see how it goes:
2%
6%
9%
MK
MK
18%
30%
MK
And definitely Yes, QTR is the easier way to go.

I note that the ink order
below includes a toner. I think my initial comment to
the
OP was about ink order related to Eboni-6, which I read
as
not including a toner. I am not sure my "follow
the
color wheel" approach to make Eboni-6 on this class
of
printer (which I believe to be in the same general family
as
the old R1800) Epson driver compatible will work if there
is
a toner in the inkset. I probably posted some profiles
for
Eb6 in the R1800 that assumed 2% MK in Y. Those
profiles
will cause the highlights to be way too cool if Y has a
light blue toner in it.
With the standard hextone
printers, the blue Photoshop curve can easily control
yellow
position ink. Thus my recent variable tone inksets
usually
work very well with that toner position. And if I had
an
R2000, I'd still start with the color wheel
positioning. It may take some experimenting to see how
the
setup works with the toner, however. The Epson drivers
for
these printers that include more than the standard CMY
colors don't fit the Photoshop curves model as
directly
as the hextone printers.
QTR control is almost
always the easier way to go.
