I’m in the process of producing photopolymer plates from reduced
images of my ink paintings. In order to get a good solid black and
clear negative, I’m using Thermal Negative Film (TNF). Has anyone
here worked with this product? It uses a developer that is sprayed on
after the film has been exposed. I’m wondering what the developer
chemical is, and if it might be able to find it locally. I’m running
through the small amount that came with my kit fairly quickly.
