Re: TiO2, Baryta and optical brighteners .. was Effect of aluminum-based coating

2007-10-09 by john dean

I know. It is all a science experiement and we are the lab animals.

Breathing Color has the bright white rag paper and canvas out there
now that they promote as having no obs's at all. They do give the
illusion of better gamut and dynamic range, and make Photorag for
instance look off white. It becomes a situation of terminology. What
is an oba, and does another whitener ( almost all papers have some
kind of whitener) have any added stability benefits, or could they be
worse.
