Digital BW, The Print

Josh-

A few thoughts.

This is an extremely large reversal and my first idea would be to not 
spray the surface before printing.  Secondly, I'd try the EEM paper 
type.  Thirdly, you might have to use a RIP for ink limiting.  If you 
are using the 2400 driver, you could try ink limiting on the order of 
5%.  I found none of this useful (I didn't try a RIP) on the 2400 
when I had reversals, and my reversals were very modest compared to 
yours.

My QC comment was about the Premier Hot Press Smooth and Textured.  
Both showed extremely bad QC, and the coating on the smooth was 
inconsistent and often damaged.  Such surfaces would make it 
impossible to print a useful target.
