David,

    Thanks for the reply.  It is appreciated.

    I must not be conveying correctly the amount of brightness I am 
seeing in the proof and print.  It is far outside the range 
of "viewing light" differences and a much greater variance (proof 
non-proof) than I have seen on any commerially available profile.

    I dont think the issue I am seeing is paper related as the 
bright profile lightens things MUCH more than the vendors profile.

    I will try to adjust the Ref White and Ref Black.  I hope this 
will work as I don't think my expectations are out of line.

    I don't expect a perfect match, but I do expect the variance 
between proof and non-proof to be similar to commercial profiles.  
If I have to make large adjustments by eye, then I see little use 
for buying and making profiles.  The profiling software should get 
me very close.

Regards,
Darrell
