Well, the good news is that I just got a test print I could live with.
The bad news is that it was on the last sheet I had for testing -- but
I can get more paper, so it's not that bad.
The profile of the watercolor paper has a white point of XYZ = 0.816,
0.919, 0.732; according to Bruce Lindbloom's online calculator, that's
238, 245, 239 in ProPhoto RGB. (It's also decidedly green, while the
paper is yellowish-tan.) When I used Photoshop's color correction tool
on the highlights to get a spot of the bare paper to match those
numbers, and when I used absolute colorimetric for the gamut-mapped
linked profile for printing, the print came out very close. There
isn't any ink on the parts of the original that were bare paper. The
highlights are very slightly washed out, but I'm pretty sure I'll be
able to tweak that the rest of the way. I'm sure it's already ``good
enough'' for Mom, but I /do/ need to figure out how to do it
``right''....
So, is there any chance that this could instead be done
colorimetrically? Do I need to start with a better profile for the
camera...?
Cheers,
