Not sure where to start searching. Maybe I can be pointed to the right archives, or someone can share their experience. I can make high resolution film at work for my commercial printing plate making process. I'd like to use it to make large contact prints. Since the output is full contrast only - no tones - the only gradation would come from a dot screen, or a Diffusion Dither screen that I apply in photoshop to a bitmap TIFF. Does anybody work this way? Any pointers for a beginner? Thanks.
