You need to use a MacBeth chart to do this. A reflective IT8 is a Cprint and
you know what re-photographing a print is to film.

It is possible but obviously getting quite a bit further from the intention
of the profile creation using IT8 chart or other. With materials that are
not flat you may end up switching spectro geometry as the 0/450 will
probably send back too much flare. If Robin doesn't mind I'll send you do
his site where there you'll find more than enough insight on this topic and
many more.
