Thanks for your thoughts on this subject.

1. I first used perceptual rendering, then did a series of test prints
using also Relative Colorimetric and Absolute Colorimetric.
2. I have tried both checking on and off paper white and black simulation.
3. I use a Solux viewing lamp to view the prints. 
4. I use SpyderII Pro set to D65 and 2.2

I originally did a profile of the Epson Radiant Watercolor using the
smaller 225 patch. But wasn't completely satisfied with it, so when I
upgraded the software to 2.0, I went ahead and printed the 729 patch
plus the extended gray patch. This new profile was improved over the
original 225 patch profile. I don't know if it was using the 729 patch
plus extended gray patch or the new software version, but the standard
test target printed a very close match to the soft proofed version on
my screen. It is just some of the art prints have these hues, which
cause problems. They are close but not as close as is possible, which
I know because I can do localized color adjustments and get them to be
almost a perfect match. So I don't know where to go from here? I have
posted these experiences on the DP Review printing forum to see if
people using other profiling systems and are trying to get highly
accurate color reproduction find the same problems.
