Digital BW, The Print

Using the Harmon profile and Imageprint,I printed a b/w picture (rbg 
mode)and got a  strong magenta cast. Printed with epson2200 pk 
WtrClrRadWht and got a neutral print. Why a problem with the Harmon 
profile? What profile do you use?

Which Harman profile? Where did you get it from?

You can't use the one from the Harman site with ImagePrint ... the one
from the Harman site was built for the 2200's native driver which has
a strong green bias on the gray axis. The profile corrects for this by
pushing things towards magenta. If you try to use this profile with
ImagePrint (which already is quite neutral) then you will get magenta
tints.

You need to check the ColorByte site for their own profiles for your
printer for Harman. (Or have a custom one made.)
