Digital BW, The Print

Paul,

I thought the steps had to be evenly spaced, but maybe not if you  
were able to generate an icc profile.  Can you post the text file  
that was generated when you made the icc profile?  I'm just wondering  
how Create-icc  treated the uneven steps.  My experience has been  
that the icc profiles improve shadow separation in 2400 ABW prints,  
rather than compress the data.
