I also use that method many times. That's what I know as "Intermediate Binding" and I agree that most of times it's the safest choice. Best of both worlds. And intermediate binding is more or less possible with GIMP (using Separate+ or CMYKtool). I proposed some time ago some enhancements to Separate+ to address specific examples like the one you pointed out (rich black) and other specific situations where primaries end up used more or less like spot channels. I agree there's a sort of gap there in late binding. >> I did some tests sendind the same files to different providers both in >> RGB and CMYK to see what happened.

I guess I can blame the poor CM skills of the people who printed the samples, but it was a real world case and RGB gave better results when the provider asked for generic profiles instead of sending a custom profile. I guess that having a custom profile I would have received pretty much the same sending RGB or CMYK. Gez. P.s.: It was worth it, indeed. ;-) _______________________________________________ gimp-developer-list mailing list gimp-developer-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gimp-developer-list
