QTR-Quadtone RIP

Yes, there is still a slight amount of metamerism when the Y ink is  
used, and although it is noticeable in gray ramps it is not bad at  
all in normal prints.  Should be dead neutral in daylight and  
slightly warm/selenium toned look under incandescent lighting.  At  
least there is no ugly green/blue shift.  The Y limit is currently  
set at 3 and you could decrease it further although that would tend  
to cool the grays somewhat.  Pity that Epson didn't make a 7 color  
Claria printer with a light gray ink.  After seeing these brilliant  
B&W Claria prints it's hard to go back to pigments on glossy papers.
