Digital BW, The Print

The WorkForce 30 appears to be an inappropriate platform for the Noritsu-Epson dye ink approach.

In a several month, low usage setting the WorkForce 30 with the dye inks in it may have had the ink simply run through it. 

The dye inks are made for the 1.5 pl printers, and I have not seen any evidence of ink loss on the 1400.  Also, the R220 appeared to have none.  The R220 may have a smaller drop size than the Wf 30.  

If the picoliter drop size is a significant variable, there is a WF 40 model that may have a smaller drop size  -- the WF40.

The WorkForce printers I've used -- WF 30 and WF 1100 -- so far appear to be good "EZ" types of printers for matte printing with pigment ink.    
See http://www.paulroark.com/BW-Info/C88-C13-5.pdf for a similar setup for the C88.  It may be that a standardized LK density for the midtone ink both works better and brings the "EZ" approach within a large, competitive market for LK density inks.

So, the WF 30 gets a Eboni/Carbon-6 18% (M & LK density) setup next.
