Thanks Paul. Terrific information. Wasn't thinking of using the
Eboni to dilute, but the MIS Archival Black as suggested on the site.
The clear base should be all I need as I don't print b&w on anything
but matte stock.
It may all be moot anyway. If I can get what I want with the UT2 inks
then making my own wouldn't be necessary. But still might be an
interesting experiment.
I hadn't considered the UT R2 inks because they weren't recommended
for the 1280. I guess what I was thinking of was something along the
lines of the FSN set but with 2 additional shades for perhaps even
better tonality and gradation.
