I'm modifying an Epson R380 inkjet printer for use as a direct resist printer using Mispro inks. Can I just load the black cartridge with the yellow Mispro and leave the other cartridges empty? The print head has never had ink in it, so leaving the other heads "dry" shouldn't be a problem. If I convert all colors on the board design to black, will the printer just use the black cartridge, or will it try to mix black using the other colors? Thanks for the help!
