100% Eboni is rather neutral on the 1400 also, but the dilute inks are
warmer there.  I don't know if I have data anymore (backup didn't restore
Spyder data) that shows the net result of 50:50 Eb6:BO on the different
printers, but my feeling is that the 3.5 pl drop version ends up more
neutral.  There is probably a more noticeable graininess in the 3.5 pl
models, but at arm's length and in an actual display print, I doubt anyone
would notice on Arches.

By the way,  I'm using a 1/3 Eb6,1/3 HP, 1/3 BO profile combination a lot
for a totally flat Lab B (level from paper white through 50%, then cooler)
even more neutral looking print.  I've put some graphs on page 10 of
http://www.paulroark.com/BW-Info/7800-EbHP-2013.pdf that shows the Lab B
values.  With what I call the "333" approach (33.3% of Eb6, HP, and BO
profiles) the carbon content of the print is probably over 80%.  The Eboni
profiles are 100%, and even the HP profile has the Eb K as well as HP
neutrals probably being 50% carbon.  Given the very stable HP gray
performance (very little green shift -- 0.1 Lab A reduction for 50% gray
patch at 200 Mlux-hrs [see http://www.aardenburg-imaging.com/ HP on HPR
Pearl test]), I have a very high confidence in the print longevity with
this approach.  I would imagine the Epson HPn paper will fail before the
image changes noticeably.  I'm using this approach with Epson HPn for the
predominantly carbon prints in my upcoming Sept. Gallery Los Olivos show (
http://www.gallerylosolivos.com/Roark.html).  (Most of the show will be the
glossy dyes on metallic paper.  But I'll have samples of the more serious,
higher end fine art there also.)
