Digital BW, The Print

Hi Roy,

many thanks for the update. Now the highlights are MUCH better (7600 
with UC matte)! Nevertheless a few questions:

- Which dithering algorithm do you recommend ? I was using "Adaptive 
Hybride". The lighter black ink patches of the ink pattern page do 
not print uniformely. What might be the reason ?

- The overall neutrality could be better. I made a warm and a cool 
curve and tried different mixtures. But there seems no way to get a 
real neutral print. Some midtones have a tendency to print cool, 
other are warm. How could I improve the neutrality ?

Many thanks again,
Peter
