I have been unable to get a decent black, there is very noticable bronzing on premium glossy paper, and the overall impression is very dull and grey, not achieving any where like the results I got using full ink or black only with the coloured inkset.

The MIS pigments in the R220 can't produce the deep black or gloss of the OEM dyes, and pigments do bronze on glossy papers.  Some papers are definitely better than others.  As to the dmax, I think I was getting about 2.1.  A spray after printing will increase the dmax and take care of the bronzing.

Assuming all the nozzles are firing and the inks are correct, they should print with a reasonable ramp.  Making custom ICCs is always better than canned.  I don't know how much variability there is in the printers (or inks).

Yes.  That could explain the posterization.

Good luck with the inkset.
