While an interesting approach, doesn’t this defeat the purpose of OBAs in paper
which is to improve the paper brightness? The whole point of OBA paper is to
take advantage of UV excitement of the dye. You would need to consult with the
client and show him/her a sample under UV-filtered glazing to make sure that
they are comfortable with this approach as the image might now be somewhat
different.

Hi Panagiotis,
Will the 'various lighting conditions' have a UV or strongly violet emission?
If you can use glazing over the prints which is like Acrylite OP-3 P-99 which
filters out virtually all UV and attenuates a little of the violet end of the
visible spectrum, the OBA content of the paper will not be excited and you can
use M2 measurements to build the profile. This is your best bet since you can't
change the paper choice of your client.
