I'm also virtually doing BO printing now also.  In my latest printing 
I've been using nothing but 100% Eboni MK and the 2% dilution (Eb/C6-
Y).  

In the 1400 even 100% BO is very smooth.  When one adds the best of 
the Eboni-6 or Carbon-6 dilutions -- the 2% (most neutral, smoothest, 
most physically stable) -- to the 1.5 pl BO capability, it's a very 
interesting option.  It tends to make an inkset that allows almost 
continuous sliding between the end points of both the concentrated 
and dilute printing approachs.  I think this has great promise as an 
easier and more flexible approach to 100% carbon printing.

Next I'll take this to 3 positions of each for more smoothness and 
redundancy.  K2/3, particularly for large format, appears within 
range of this approach.  My 2200 is going to be pulled from the C6 
test and put into a 2%-100% test mode.

There is only one ink to mix, and only 2 bottles to bother with.  
Both are very stable.  I expect further generic developments, and 
lots of different types of MKs will probably work.  Epson MK appears 
to and is just of few Lab Bs warmer than dilute Eboni.

I've been using QTR and the sliders to control where I want the 
alternative characteristics of the 2 approaches (Eboni is very 
neutral, 2% is medium warm.)  The QTR controls allow mixing up to 3 
profiles and varying which one (for example warmer or more neutral) 
you want in overweight in different parts of the image ramp (e.g., 
highlights).
