Hello- I'm a graphic designer, but I never heard of anyone ever actually using a Photoshop DCS 2.0 or 2.5 EPS file before. I have recently picked up a freelance client who has specifically requested that I use the Photoshop DCS EPS files that they provided to me, explicitly telling me not to convert them. When I was in school years ago, no one ever talked about DCS files, and even at the agency I worked at (I'm a corporate design guy now) we never used or even talked about DCS files... So I'm looking for someone to shed some light on this for me. Thanks!
