You said to try the luster profile, but I am not sure what you mean by adding a blue curve. I really didn't like the warmth of skies with the canned profile, so I need to do something about that.
So far I've yet to see evidence of a profile that actually adjusts the ink amounts to compensate for paper colour. What I do see is that profiles show the effect of the paper colour when used to soft proof.
Andrew Rodney has an excellent video tutorial on soft-proofing on his
Digital Dog web site: click on the link to
Color Managed Proofing and Printing with Photoshop CS3. This demonstrates how to create a Photoshop curve to correct for any divergences between what the soft proof view shows you and what the image looks like without soft proof view turned on. Part of what needs to be done is a general brightening of the image using the RGB "channel" of a curve; part, in the case of a warm-toned paper, is to go to the blue channel of the curve, grab the output line, and move it
very slightly up and to the left. Once you get a curve you like for a given paper, save it and re-use it for each print you do on that paper.
Again, this is not a matter of compensating for a defective profile, but of properly exploiting an accurate profile. Personally, I don't see why an accurate profile could not optionally build in both compensations; but if that's possible I haven't seen it.
