well, I wouldn't be printing these myself, so im not sure what ink we would be using. But basically we want to make limited prints similar to this --
indiemerchstore.com - Zoom
maybe a two or three color print on some sort of high quality paper that has a clean border like the one in the link.
im thinking having them digitally printed might be the answer, but I REALLY want the screen printed look and feel. It seems more like an "art print" instead of a poster that way.
