Going to be printing some RA-4 at home for the first time in a few years, and wanted to know what people are using. I used to use Tetenal Mono-PK in trays with either Fuji Crystal Archive or whatever Kodak paper was around back then. I seem to recall there being some occasional issue with yellow borders after a few days or weeks, but I don't think I ever figured out what that was. I will be using a Nova Trimate this time around, so I guess that opens up my options for chemistry a bit. It has temperature control. What do you recommend for ease of use, speed and quality (and lack of issues)? Thanks in advance.
