Digital BW, The Print

I used the Lyson QuadBlack inks with a CIS in an Epson 1160 for a few years until I sold the printer about a year ago (to a pro photographer who was very happy with the print quality). I must say that I found the ink set completely useless with the Epson driver - very poor Dmax, and bad banding. That was when my desperate internet searching led me to QTR.
Being an i1 user, and familiar with colour profiling, I found that I was able to generate QTR curves *relatively* easily. The results that I achieved on glossy papers were very good. Not just my opiniom but judges in club, national, and international photo competitions too.
I found I got the best results on Ilford Galerie Classic Gloss (swellable coating) which gave me a Dmax of about 2.6, and pretty smooth prints. These prints are faring quite well on the wall too. No obvious change after three or four years; not long when we are talking about archival qualities, but good enough for many people.
The metamerism that Tyler mentions is undoubtedly present, but I did not find it excessive. It only appeared when prints were viewed under low colour temperature tungsten illumination, when the prints took on a slight red cast in shadow regions. I think this is inevitable with dye inks because most black dyes begin to tranmit light from the deep red, becoming pretty transparent in the near infrared. The very strong red component of tungsten light is partially transmitted by the dye, and the red light reflected from the paper gives the very deep red cast. No problem incidentally with halogen lamps, and they look perfectly neutral under 4700K Solux.
On the plus side of course, if you like glossy prints, there is no bronzing and no gloss differential. Not much clogging either in my experience. However, if you are only interested in matt papers then the modern carbon B&W sets will certainly be your best bet.

Also, unless you are an advanced user at home with custom setups either through extreme RGB curves and the OEM driver, or custom setups with a RIP, including QTR, I am not aware of any workflow commonly available for them that will rival the quality the contemporary inksets and workflows can attain.
