Joe, what size pictorico are you using? Has it been made available larger
than 11 by 17 yet ???? I know that Adorama sells the 11x17 ... any other
ideas?
My experience with acrylic spray, incidentally, leads me to suspect that
it could impair the inkjet if applied BEFORE printing -- it tends to make
some kind of stipple (though I suppose possible to avoid).
