What color mode and profile do I select? RGB or CMYK?

For inkjet fine art printing, we use RGB mode with color profile Adobe RGB 1998. You can learn how to change the color mode and profile here. Our Epson Inkjet Fine Art Printers use up to 12 colors to produce the widest color gamut. We convert all the files to Adobe RGB 1998 and send the RGB files directly to the printer for the best outcome.
