QTR-Quadtone RIP

FYI: I did some more testing with test wedges and comparing of print 
against monitor. It looks like the prints of the gray-lab converted 
file match my monitor better than the gray-matte converted files (as 
said: printing on Epson Enhanced Matte). 

Again another reason NOT to convert to the gray-matte profile? But who 
am I to ignore the instructions of an expert like Roy? Am I right or do 
I miss something?
