Digital BW, The Print

Paul,

I never tried your alternate inks position suggestion - I was too 
busy printing photographs as opposed to test strips (finally!) to 
mess with the work flow. But the engineer in me is always looking for 
a good experiment, so I will give it a go. The guys at LincolnInks 
have been suggesting a tri-tone solution without partitioning for 
quite a while now, and that may well be the way to go!
