Metamerism is a physical property of the ink; you
can't fix it with workflow.

Metamerisms occur when the shape of the spectral response
curve of two different inks are different.  In a 7-ink system
like the 2200 if you can identify the inks that have the
peakiest response curve you may be able reduce metamerisms
by not using so much of those inks, although this would
take special drivers.

The metamerism problem with the 2200 is noticable but
not horrible.  Yesterday I took the black and white sample
on the Enhanced Matte that came with the printer (the sample they
gave me was a skyline of Paris)  and took it with me shopping.
That way I could look at it in lots of different lighting conditions
in stores houses and outside from early afternoon to
evening.   It stayed pretty neutral in every condition except
bright sunlight with blue sky, in which it looked somewhat
greenish, especially in the light grays.
