The issue with FWAs is the amount of UV excitation available in the
print viewing environment is usually unknown and uncontrolled. Prints
viewed in illuminations low in UV light will not have the same look as
viewed in conditions with higher UV light. Also when comparing prints
made on different paper stocks, the amount of FWA in each paper will
give each a different appearance. Using the UV Cut filter puts all the
paper measurements to the same reference point.
That may well be true, but is it at all useful ? There's no point if
the resulting prints look different, because you've ignored the
effects of FWA.
Unless you are going to illuminate and view all the prints through the
same UV cut filter you used on the instrument, the FWA is there, and you have
to deal with it.
