Is this Ultrachrome K3?  I don't have this with my R800, but that's the
photo-pigment-but-not-really-pro-oriented inkset (and does gloss by
having a separate cartridge for gloss overcoat; only printer I've seen
that can make decent glossy prints, which are the only truly
photographic-looking print; unfortunately it doesn't do B&W well.)

Generally, the problem is heavy pigment loads in dark areas floating on
the surface of the paper, producing the "bronzing" effect in those
areas.  I'm sure the black is a heavy component of those areas, and I
guess by using a special black for papers where that would show, they
can work around the problem.
