Digital BW, The Print

Hi Folks,

I'm a bit confused (seems that this is happening more and more these
days) concerning which inkset fades more.  Jon Cone says that in his
tests the MIS quads will fade (and warm) more but Paul Roark seems to
have test data showing just the opposite.

Just how noticeable is the increased Dmax (or whatever you call it)
that the Piezotone claims?  I'm printing on EAM and Photorag.  If you
put two identical photos printed with each of the inks side by side
would they be "close" or is the small increase in Dmax that the
Piezotone claims really apparent?

Thanks,

Richard Cooke
