Can someone please explain the pros and cons of using K4 ink vs. the Epson K3 ink?

Looking at the QTR site, K4 isn't listed as one of the compatible inks (only the Ultratone inks 
are listed).  For B&W prints using K4 inks, is it necessary to use QTR or is it still possible to 
use the ABW sliders?

When you say "as long as the various K4/paper combos are profiled properly", can you 
explain what process you are referring to?  Do you mean generating custom profiles using 
QTR and a scanner for each paper and ink combo?

Thanks,
Chris
