Julian, I surmise from the subsequent exchanges that you were printing the
negs with full color. My tests with 1160 dye inks in black only showed no
change in about a year.. on various substrates.
I have BTW found with normal gum printing, which you seem to have been
using the negs for, the dot gain is such that I'd expect extra dpi from 4
colors of black to be more or less irrelevant. Is it possible the
"grainy" look you found was due to different responses to the color
dots????
PS. Somebody asked about West star inkjet film from West Jet co. a while
back (or maybe it was West Jet from West Star co ?). I tested that
substrate against the Pictorico & found it as good with the 1160 (which is
admittedly obsolete these days, more's the pity)... at about half the
price. There's a comparison of these and other substrates in Post-Factory
#8, p.39.
