Digital BW, The Print

I've been using MIS Ebony for black only prints in the C86 and have 
made some good prints.  Now trying the EZ warm inks the tone tends 
towards a sort of pale sepia and to my eyes it has a slightly pinkish 
tone.  I've experimented with the sliders and got the best results 
from cyan +25 mag -18 yellow -18.  Another difference I've noticed is 
that if the print is viewed at an angle the ink in the dark shadows 
has a mottled effect, a slightly lighter shade lying on a darker shade 
on the surface; this is not the case when the ebony ink is used alone 
for BO.  I've been using Epson matt paper, nothing I've seen so far 
from the EZ inks warrants anything more expensive.  Lots of people 
seem to be very pleased with the Epson r2400, until I get mine I think 
I will be return to BO printing; which I've read is supposed to be 
more archival too.
