"Ready" doesn't pertain to files either does it? Last time I really saw a camera ready file was prolly the last time I saw a PMT!
Since we do mainly small run spot color stuff we still get camera ready art including old PMT's . Usually this stuff comes from customers who are e-tarded, use non GD programs or from business owners that demand we return their artwork. Occasionally we will get in some ancient artwork with tons of overlays and non photo blue lines nicely rubber cemented on a piece of board. I can only imagine what a pain in the ass it would be to make corrections to something like that.
