Hi Bill,

I though of treating some imagesetter film with dye, but there's no practical way to get the goods into the film. It's designed for very rapid processing (under 1 minute), and as such the existing dyes, anti-halo etc., wash out if one tries to soak it in erythrosine (or other) solution.
Imagesetter film doesn't make a very good camera film, but it does make a very durable film base if it's fixed and washed
