Digital BW, The Print

I've had an opportunity to test a couple proposed 7800 carbon ink setups on an Epson 2400.  Because both the 2400 and 7800 are Epson K3 printers, I'm going to assume the setup that works best on the 2400 will also work well on the 7800.  So, this is what I'll load onto my 7800.  I'll use the C6c base, but I've noted the MIS Eboni-6 equivalent in parentheses.  Eb6 and C6 print essentially the same.

K = 100% Eboni;

LK & C = 30% Eboni (Eb6-C);

LLK & M = 13.5% Eboni (Eb-"EZ");

(See http://www.paulroark.com/BW-Info/C88-C13-5.pdf -- 13.5% Eboni is made by mixing 2 bottles of Eb6 inks: LC-9%, and M-18%.)

LC & LM = 6% Eboni (Eb6-LM);

Y = 2% Eboni (Eb6-Y).
(2% Eboni is a stable suspension.)
(The LM and LC 6% inks in the 7800 setup above make smooth highlights even without the 2% inks.  As such, Y can be a dilute HP PK if more neutral printing is wanted.)

Though I'll mostly use QTR for my printing, this inkset prints well with the Epson driver also.  I think this is important to support a variety of applications and file types. 

This Eb/Carbon-6 inkset arrangement will support my wide format tube refreshing modification if and where needed.  Because of the use of the middle dilutions in two channels, I sometimes refer to this as the C6 "Dual" inkset.

I'll summarize my 7800 Eboni/Carbon-6 workflow in a PDF and post it at
