Digital BW, The Print

Josh,

My default ink limit for the k7 inks (Epson 4000) on HPR is 75%.  I  
looked at the IJM quad files and they seem to all be limited at 95%  
(which seems quite high).  So, if you are reducing ink limit in the  
driver by 25% I guess that would put the ink limit near to what I'm  
using.
