Very interesting.

I'm told that the big-format HP and some other printers use solid colorant
pigments.  Apparently they have very long lives (resistance to fading,
etc.), but rather low gamut.  For the desktop, I'm also told they had not
yet been ground finely enough to avoid clogs on our Epson printers.  If
someone has succeeded, this could be a true advance.

What black do they use?  Do they have a pure colorant that is blacker than
carbon (more like dark brown, from what I can see) and just as fade
resistant?  If so, that would be of real interest as a quad feedstock.

Good luck on the tests.  I hope they don't clog your 1270.
