Yes, they are qidf files for the 1400 that only use 4 inks.  I can send them
off list.

I probably should not have used the name "quad" -- wasn't thinking of the
confusion that might cause.  I just used the maximum amount of Y and LM (the
lightest inks) to keep the Lab B down.  Then, of course, the 100% eboni and
a little bit of C (the darkest dilution) was needed to smooth the shadows.
So, 4 inks turned out to be very good on the 1400, and I'm hoping it'll work
on the 1800.  

Due to the banding tendency of the 1800, I'm assuming we'll have to use more
dilute inks than 4.  Whether one would want the full Eboni-6 or a subset may
vary.  Again, the hard part is to get a 100% carbon print that can pass for
"neutral-cool."  Warmer is relatively easy.  For that, however, I can see
some wanting to put in the full inkset so the warmer midtones could be used.

The Y, LM and C, as well as enough Eboni for not only the MK position but
also at least one other would be needed.  I intend to try and keep the 3-MK
workflow as is.  On some papers multiple MK channels can reach a higher
dmax, and many really like the 3MK workflow.  It's another profile that
would then be able to be mixed with the dilute Eboni-6 profile(s) to get
intermediate results.
