I'm currently in the process of launching a home-based screen printing business. I have an epson r2400 inkjet printer. Im looking for ways to operate at the lowest cost possible yet efficiently! I'm looking into purchasing a bulk ink system. I'm only using this particular printer for printing film positives which only require the usage of black dye sublimation ink. Can I filled all slots with the same color ink even though the slots are color coded for magenta, cyan, and yellow?
