The neutrality moves from Cyan to neutral to Red/Magenta throughout the
scale of values. This is using a White dibond profile.
One wonders if this is not a "bronzing" effect that can happen with
water based inkjet inks on RC gloss papers too. Which is not in essence
a profile creation problem but an optical effect related to the
pigment/ink layer thickness. The color changes for every reflective
angle. With a varnish applied the effect can be reduced depending on the
type of varnish.
There can be a mismatch of a white (polyester lacquer) DiBond profile
used on an (anodised or transparant lacquered) brushed DiBond but
consider the first option too.
For a custom profile there are of course issues when targets on
reflective metals have to be measured with the normal spectrometer
optical geometry. A "bronzing" effect already happening in the printed
target will add to the complexity of the profile creation.
