I have an Epson Stylus R320 that I want to use with transparencies for PCB artwork using photosensitized FR4 and UV exposure. I use a row of 20 UV LED (395nm) that I mounted on an old HP scanner so I can control the exposure to UV.
How is it possible to increase the resolution of the print?
Thanks,
Jean-Paul
