[argyllcms] Re: Could someone help me understand something applying printer profiles.

Hi,

Unfortunately not really - my observation was that the RGB numbers in

Yes, that was a quirk of the Gutenprint PostScript output driver, and as far as I know it doesn't happen with current versions. 


(In order to obtain the right colors I had eventually profiled the
output RGB color space of the print plugin at that time, and made a
PostScript CSA for it which I assigned to DefaultRGB in a PostScript
prologue, so that sRGB images printed from gimp eventually came out with
the right colors)
A very neat illustration of the fact that profiling measures not just the response of the printer, inks and paper, but also the driver! 

All the best,
