I'm helping a friend in Middle Tennessee who owns a sign shop tweak-out his large format digital printer to print super opaque, large format film positives for screen printing. Mainly for selfish reasons... I'm done with laser vellums, warped positives, cutting and pasting, dealing with dumb fucks up at Kinkos, etc.
He's been great through the trial and error process and I think we've about got it dialed-in.
He asked about offering this as a regular service to people like us and I've offered to handle the file prep end for him if necessary. In other words, it's beginning to sound like a joint-venture for the both of us.
My question: Are there companies offering large format digital positives to our industry and if so, who's doing it well? Any first-hand experience dealing with such companies would also be helpful.
