[argyllcms] Re: Absolute colorimetric - dark saturated colours excessively light

Yes, I'm talking about Absolute Colorimetric. I was under the impression that luminance errors are generally considered more objectionable than saturation errors. Maybe I was mistaken?

I guess, since no-one seems to think that the plain-paper result I got was unexpected that my expectations were unrealistic.
As long as all in-gamut colors are reproduced colorimetrically correct (within some tolerances), the results can at least not be considered as "wrong".

And the remapping of out-of-gamut colors is rather an issue of art. As I said, the ICC spec doesn't tell, _how_ exactly it must be done; it is implementation dependent. Graeme has chosen to clip to the nearest color in CIELAB or CIECAMxx space (-> lowest color difference). You cannot say, it's right or wrong - but of course you may like it or not (as you may like or dislike a painting or another work of art). But I do agree with you, that I subjectively find the out-of-gamut clipping done by ISOcoated.icc and ISOnewspaper.icc more pleasing. This applies particularly to small printer gamuts with a high black point.
