I think you'll have to edit the colors. It may be that the colors are
outside the gamut of the printer and they're mapped that way. PrintOpen has
some very fine controls to bias the separations in perceptual for gamut
mapping rich colors, yet sometimes or rather often to achieve perfect colors
one can tweak the colors that aren't quite there yet. Albeit slow I use
Profile Editor from Gretag to edit selective color one by one. This even can
take care of problems like the HP10/20/50 magenta needing more yellow to
come anywhere close to process magenta. Although it would be nice to see a
profile make perfect color the first off profile, I've never seen this yet,
but still hoping!
