As someone who's company built some profiles (10 printers) for Epson
(http://pixelgenius.com/epson/) I can state colorimetrically if necessary, that
changing the settings do not invalidate the profiles.

The goal wasn't to make profiles that look good per se. We used a 5000 patch
sample, X-rite software and an iSis, half a dozen printers from around the US
and averaged all the data to build the 10 profiles.

Got a printer listed in the URL above and Exhibition Fiber paper? Try the
profiles and let us know.

There are not that many knobs to fiddler when making such profiles.

There are not that many knobs that will screw anything up. Getting good output
of a good set of patches properly printed is kind of important no question.
