RE: separations for gum printing
Hi Marek, The difference is deeper / more drastic with uncurved negatives (since the curve darkens the thin parts of the negative). I'm not criticizing anything in your new / different workflow. I just don't see the same thing as you do, when I do it myself, and wonder why? Thanks for sharing, Loris. 22 Kasım 2008, Cumartesi, 5:46 pm tarihinde, Marek Matusz yazmış: > > Loris, > A better example would be an uncurved set of negatives.
