for paper brighteners by using relative measurements instead of absolute
measurements where essentially the apparent color of the paper is removed
from the paper white reading, and pretty much all highlights, tapering
off through 1/4 tones and midtones. Densitometry has had a similar
concept when accounting for paper reflectivity in density measurements,
or not.<
I don't agree with doing relative measurements for profile-making. It is
not very interesting knowing what color the ink is independently of the
substrate for color management. What is important is what color is seen
when that nuetral 10% gray patch of ink is put onto a Cromalin subsrate, for
example, giving it a reddish tinge. I don't see the correlation with
density readings either. With density or ink film thickness measurments,
one is not dealing with colorimetric values. You want to know how much ink
is on the paper (for example), so you zero out the paper. With color
appearance, that is not the case.
