Digital BW, The Print

Paul:

I took my post down after reflecting on my process some more and going back to re-do the head alignment. This seems to have solved the problem, though I did not go back a print a full 11x14 - I tested with a full scale sample area. 

The alignment seemed to solve the issue, but your comments are very interesting. As you note: matte paper OK, gloss (satin) paper more susceptible to micro-banding. Also, I was using a color curve to cool the image, so I would be using more of the cool tone ink. 

So now I have a good answer and a means to solve the problem. Best of both! Thanks for your help. BTW, I went to LA last month and had enough time to go the Walt Disney Concert Hall. What a structure! I considered heading up your way, but 'your way' was a bit farther than I had time for. I'll have to continue to settle for viewing your work on the web. Maybe next trip.
