Is there anyone on the list using strickly "Spot Colour" negs instead of
CMY(k) or RGB negs in Gum? I've been poking around the T-Shirt printing web
sites (still looking for inks and transparency materials) and this seems to
be a common way of separating colour in a photo editor when printing with
screens. It's common to see them using six or more spot colours to achieve
the "look" they want. Is anyone combining the two methods? I was thinking a
metallic silver layer to pump up the reflectivity of a piece I'm doing that
has the silver scales of fish in the subject.
