Using PrintFix Pro 2.0, I created a 729 patch plus extended gray patch
based profile for Epson Radiant White Watercolor. The paper that many
clients have me use for making prints of their artwork. When I tested
the profile by printing the standard test target provided with the
software, I felt very satisfied. In all respects the printed target
was a very close match to the image on my screen (profiled with the
SpyderII Pro). However, when I make prints of my clients artwork, I
find that often subdued hues do not match the soft proof version on
the monitor screen. For example tan colored shades will look too
greenish. When I do a gamut check in Photoshop CS2, the colors appear
to be in gamut. In theory it seems that the color can be reproduced by
the Epson 2200 that I use for printing. By doing localized
adjustments, I can get the inaccurate color to be a much closer match.
But I use the PrintFix Pro profile and the appropriate printing setup
in Photoshop color management to avoid having to do this.

I can not figure out a solution. If I saw a general color inaccuracy
in the test image, then I could tweak the profile using the software.
But I don't see the inaccuracies that I see when making these art
prints. It is not that the colors in the prints are way off, they are
a just a little off, but enough to be noticeable to myself and the
client. I have carefully following the procedure for reading the
patches and checking them, properly calibrating using the provided
white patch in the instrument base before reading the patches etc. Any
suggestions on how to get a more accurate profile?
