Yes, that is the thing, you need to test several media settings in the 
RGB driver by printing out total black patches and comparing them with 
the spectro readings. Most likely they will all differ.

What I didn't know is that the speed has a real effect on this also. If 
one slows down a printer a lot, say from 1440 4 pass to 1440 8 pass on 
a large format printer, should one see a measureable difference in 
damax...? And if so which should be the higher dmax and why? The slower 
speed?
