Digital BW, The Print

Hi Paul

I made three test prints that included a 100 step and offset gradient.
One was done with "no color adjustment" checked, one with ICM, and the
last with "Color control" checked with no adjustments applied. 

The results with the 5.20as driver are:
-ICM: Pretty neutral. This setting is what i normally use,and is what
I used for my last reply. Interestingly, if i remember correctly, it
looked the same as "no adjustment" when I compared the two printed
with the 5.21 driver.

-Color controls: Looks identical to the print made with ICM checked.

-No Adjustment: Unfortunately, this one looks pretty much the same as
the prints i was getting with the new driver, in terms of color. i'll
wait a day or so for the ink to dry before i compare density. 

Please let me know if you want me post any other settings i use, and
remember, before you go trustin my judgment, I'm sorta new to all this
so there could be any number of varables i'm missing;)

thanks
john
