Eboni MK is available from MIS (I assume) -- premixed to all the dilutions or in bulk, which can be mixed with, for example, generic base C6b, which I use and mix, and which is also available from MIS for cheap.
If MIS does not have the Eboni MK in stock, let me know. It's available by the liter from STS at least with a special order approach. (I don't use the STS web page; MIS is the normal retail outlet for this product.)
I recommend the blue toner mix described on page 3 of http://www.paulroark.com/BW-Info/3880-Eboni-Variable-Tone.pdf . It's Canon Lucia blue and cyan, diluted with generic base C6b. It's also what I just loaded into my "new to me" 9800. For matte paper, it's the best I've found. As far as I know no commercial outfit is pre-mixing this. I9;ve given the formula in UT14 color toner terms to MIS. It's there if they want to mix it with their pigments (though I don't know the status of the availability of those old color Image Specialists colors). I understand that most don't want to mix these, but that is also what sets us apart.

Paul R.,
So - my memory served me well, that you did talk about the Epson driver... it's in the very first paragraph of your pdf. I downloaded that when you first reported on this research. Some of it is over my head, but I do get the general idea. Apparently a sticking point is the availability of a compatible blue in bulk, as is Eboni, so we end users can mix our own neutral inkset. You're right, it is easy. I'm on my second batch, more accurately called Cb6 instead of Eb6. I'm using an Ohaus scale, which measures to .1 gram - I do 100 ml mixes and store it in 125 ml plastic bottles from MIS. The bottles are my tare weight.
I'm eager to try it!
