Re: variable tone article question

2006-06-10 by Brian Chapman

More Info:

I expected that the density of the full +M would cancel out the -C and
I would have a "normal" ramp with which was just warmer.  I don't know
whether the ink densities (C and M and LC and LM) are the same though
which would certainly have an effect.  

My print looks close to your -25C print but warmer with the addition
of the +25M.  

I was basically trying to find out what the warmest print I could get
from the set was.
