Re: [Gimp-print-devel] Strategy for profiling Epson R280 with Ultrachrome K3 inks

[Marko M. <mar...@gm...>]

I tried printing CMYK but can't figure out how. I think the correct
procedure, on a Mac at least is to take a CMYK image and print it
while also selecting "CMYK" in Gutenprint driver settings. This
appears to be printing RGB, since K gradient looks indistinguishable
from gray CMY gradient. How do you make Gutenprint work in CMYK? At
least from Photoshop.
