Thanks for the comparison image. Going by that (though you don't state it outright), the way-out-of-gamut problem is with my PC's monitor, and I won't have to fool around with the RBG file too much to get something acceptable in CMYK. You mention the yellow and white: The ironic thing is that on that bad proof the yellows and whites were the only colors left. All the blues and even the blacks showed up in out-of-gamut magenta. I've heard of Krita and I'll download it and see if it will do the trick. Is there anything in particular I need to know about it? The essential thing is that the final file has to be in PDF, and not just any PDF, but PDF/X-1a:2001 or PDF/X-3:2002. But I'll climb that hill when I get to it. (Incidentally, I did mention the OSs--- Windows 10 on the PC and Windows 7 on the laptop. Does that affect anything?) -- recoveringartist (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
