HP recently released a video regarding their latest ink jet printer that has driver setting specifically designed for digital negatives. They are printing 24inch negatives for Elliott Erwitt using green and black inks. I have been using digital negatives for almost 7 years now, however it is an interesting collaboration and shows at least one manufacturer is taking digital negatives quite seriously. I would like to see the actual print before passing judgement however Erwitt seemed happy!
