Digital BW, The Print

John,

This is a response by a very knowledgeable printer that I got off list
concerning the old and new 2000P drivers:
 
"The "metamerism" difference between the current drivers for the 2000P and
the original is the gray balance color temperature target, which was moved
from 3200K to about 4500K, simply to avoid the pronounced cyan appearance of
prints viewed by window light."

One additional issue is that I want whatever I do to be cross-platform.  I'm
not sure if the Mac OS 10 driver is the new or old one. 

Usually when we check "No Color Adjustment" the curves are cross-platform.
If you print with that checked in the old and new drivers, do the prints
look alike?
