PFP "Build Profile Setup" screen: click on "Ref White" on the right  
hand side.

Small screen has a check box for "Paper White Compensation".

If you have a negative number in "b", you probably (certainly?) have  
optical brighteners.

Click the compensation button and the negative number is reset to  
zero.  That made all the difference for my profiles.

Of course, you can test for optical brighteners with a "black light",  
too, but the negative number suggests something odd is going on.
