Digital BW, The Print

I always get a greenish cast from my R800 b/w test
prints (with UC
ink), even when I ask the printer to do "BO" (with the
japanese
driver). Is it just my eyes? 

That green cast (under daylight) is very typical of
Ultrachrome inks.  It wasn't your fault.  The only way
to mitigate is to use a RIP software such as Image
Print, which allows printing B&W from RGB files using
mostly the black and gray inks and just filling in
with a litle bit of color inks to smooth the print
out.  There is no metamerism, no green cast, and the
print is basically a selenium-like cold tone B&W.
