Paul,

3200K as a target for gray balance ?   I'm surprised. Where do we 
ever find (or need) a display color temperature like that ?

The original drivers for the 10000 CF, 2000P and possibly the 
5500 were changed because the metamerism was a problem and the 
droplet size allowed a longer black generation to suppress it. 
The 9500 + 7500 never got that new driver as the droplet size 
wouldn't allow it. The 10000CF that I have here shows that long 
black generation and it isn't nice. The printers mentioned were 
all to be used for the graphic market too so I guess 5500K as the 
color temperature is much more likely.
