AFAIK this mode estimates the amount of optical brighteners in the
substrate by the size of the hunch in the blue region and the gap on the
short wave end of the spectrum (I'm sure Graeme can explain it much
better than me). This estimation seems to work satisfactorily in common
cases, but why estimating if you can measure it? And what about optical
brighteners in inks? They can't be estimated this way.
Sorry, No, I've no real Idea what Profile Maker does with FWA
compensation. I can only speak about the approach I used with
some success.
