Digital BW, The Print

Robert,

Thanks for the suggestions for a selenium tone profile.  I'm still a  
novice at profile building with IJC and don't have a densitometer yet  
(should have one soon though) so I can't do any linearization at the  
moment.  I'll look forward to seeing what you develop for the selenium  
tone option and hopefully learn more from the profiles that you and  
Antonis develop.  I can see how the ink limit adjustments are an  
effective way of adjusting overall tone, with out affecting curve  
shape.  When you suggested a 2:1 ratio of M/C for the cool profile did  
you mean relative M/C curve amplitudes or measured M/C values?
