Tyler, you do the GO overprint with SP as far as I understood. QTR 
might help you there : since you go for double-pass, I'd create a GO 
channel alone in QTR and reload the print.

Now I've emptied my first cartridge set already (small 1800 
cartridges though). Annoyingly enough, when the cartrigdes get their 
new load, the output is darker for most dilutions by up to dE L*3, 
that ruins all the past effort and the curves needs to be reworked. 
Bad luck I was at the linearizing stage... So even new cartridges of 
the same ink set and you're again printing out small grey patches for 
hours. No chance any sedimentation could have happened on the small 
cartridges, I have no explanation.
