Clearly, the addition of FWA into a given paper formulation is a dirt-cheap
way for any paper mill to avoid "puryfying" paper further by traditional,
more costly means, while providing the appearance of "white".
I was discussing laser paper brand with the lab technician at the university
I teach, with their Xerox Phaser 7750 color laser printer, and right away he
told me they use Hammermill, adding proudly that the packaging boats a
"brightness of 107" for this paper. That's all he seemed to care, that they
use the "brightest" paper they can get. But I happened to have a sample here
with me that I measured and I got a b* = -9 ! I said to the technician, that
paper may have the appearance of being bright but it's blue like hell.
