Well, I go to the Duggal site and read this: "Duggal’s HD C-Prints are created on true archival photographic papers" OK, maybe somebody can tell me what a true archival photographic paper is, because I only know of C print technology for color, besides dye transfer, which doesn't really exist anymore outside of very obscure hobbyist basements. (I hope those basements are ventilated well) C prints are an almost ancient technology, always prone to quick fading, and I cringe when I see it being used in museum shows, because somebody should know better. Did Kodak or Fuji or somebody else invent a C print that doesn't fade when I wasn't looking, because I moved on to modern technology that is cheaper, much more archival, easier to produce, and just plain better?
I'm thinking that somebody invented a way to make very sharp C prints that will still fade. Maybe not. But, I swore off chemicals in 1983 when I started using computers for imagery, and, I'll never go back. Clean a Kreonite machine once, and you'll know what I'm talking about.
