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

Hi,

I'm not clear - are these two Argyll profiles, or something else ?

Those two are standard press profiles downloaded from the web. The ISOuncoated one is part of the ECI profiles package. They're both CMYK though, so again they're probably not a great comparison.

Is there anything I could tweak to weight Argyll's strategy more
I guess I'm a little confused then. You were referring to absolute colorimeter,
and there's nothing much to tweak there - you get clipping to the closest color.

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.

Speaking of Perceptual intent, though, all three Argyll profiles perform remarkably well in that regard - even the plain paper one, within the limitations of the poor black density.

All the best,
