I'll buy that. Actually the neutrals on the test print do look right. But I haven't measured with
a spectro. I'll print a gray ramp and confirm that. So if the neutrals check out as neutral, then
what else could be warming up the fleshtones and what would be the best way to adjust for
that, especially if the rest of the print and the other colors look right? Would that be an area
where the Expert target would come in handy by maybe providing more squares to sample? I
know our brains are a lot more sensitive to fleshtones than a lot of other colors where we
don't have such an engrained reference. I was thinking that maybe using the larger target
might help. What would you suggest?

Light source is the usual reason that neutrals don't look neutral; the spectro isn't viewing your print under your lighting, its using its own. Fleshtone casts when the grays are neutral would typically be caused by metamerism. The latest printers have two grays as well as one or more blacks, which minimized metamerism in neutrals, but for colors metamerism is still present; so as you move out into skintones, what you see, with a given printer, ink, and paper, may not be exactly what you expect, especially if you are not under a full spectrum 5000k light source. The only fix is to tune your profile or prints for the viewing condition in question, and live with the variation under other light sources.
