Yes, and it banded more than the Eboni-6 in the 1.5 test I ran.

Clogging is not a problem with C6 base inks.

Add 1% Edwal LFN wetting agent (available at photo stores). With it 
1.5 pl printers appear to be within what the base can handle.

C6 base is good for matte, but for glossy it only works with the 
pigments that have an acrylic type coating and thus do not depend on 
the base for the gloss.  I have not tried it with MIS PK, but I fear 
it would just dilute the Glop and reduce the gloss.  With the HP PK, 
the gloss holds very well with the C6 base.  Consider that C6 base 
uses mostly glycerol with the water -- just like the Epson gloss 
optimizer.

Good luck with the mix.  (And keep us posted as to how those carts 
work out.)
