Digital BW, The Print

I have modified my Epson 7800 setup to include not only the full Eboni-6 inkset but also to have HP Z3100/3200 neutral/cool pigments in it.  In 2010 I used a somewhat similar arrangement, and for the 1400 I've successfully used a combination of Eboni-6 and HP (or MIS UT14 cool pigments) for some some years.

The write-up of the 7800 setup for 2013 is at

There were a couple of surprises so far as to which papers would respond best to an Eboni-6 and HP blended profile (QTR dual profile and slider adjustments).  Red River Aurora Natural and H. Bamboo did much better than I expected. 

The combination of Eboni-6 and the HP pigs brings a wide variety of papers within the near neutral range that I prefer.  I doubt there is any ink setup that can match the expected light fastness and economy of this approach, which should be feasible on all Epson K3 printers.

Profiles for the 7800 have been posted.  Most are for QTR, but the Epson driver is also compatible with this setup and a curve that gives a 50-50 blend of Eboni-6 and the HP pigments should be able to make ICCs for many matte papers.
