I'm not ready to take the plunge just yet, because I've got other things on my plate at the moment but I'm very curious about how to get a massively huge negative for contact printing. In particular I'm looking at Gum Bichromate. I just saw this video Watch Massimo Attardi print gum bichromate on very large wood and naturally I thought about this before knowing it was possible. Now that I see it's possible, I want to know how to get a negative that size! What are the options? I've been searching for an Imagesetter service local to me (Central Coast, California).. not even sure there are any even in Los Angeles. Would appreciate some insight and ideas as to cost involved. I know the machines cost like anywhere from $1500 to $10,000 used.
