Digital BW, The Print

Yea John I share your interest. It is time we started getting these
ultrachrome comparison tests on all the printers with QTR.

The only one I know of who has commented on this is Roy. He said
something like you "should" get better tonality from the K3 with QTR
vs the K2 with QTR but that he didn't really notice much difference.
But these were first tests and not really in depth comparisons. He can
speak for himself, he is the best one to evaluate these perceiveable
differences since he designed the software. We'll see. I would
certainly like to know before I shell out another 5 grand for a new
machine! If this is a minimal improvement to hell with it. I don't do
much glossy work.

You would think that the added L.L. grey would improve the very light
values out of greayscale but since QTR and UC uses light cyan and
light magenta up there it could very well be that we'll hardly see any
change at all. 

Does anyone know for sure....That is a big question for anyone using
this approach.

John
