Hi, list Maybe this has has been answered before, but I have dived through previous posts and have been unable to extract a straight answer. It's about using the whole gamut of a printer, expanding if necessary. Using ICC V2, printing an sRGB image may render images that are not taking advantage of the whole printer gamut. We may choose to use the PRMG_RGB-sRGB_based.icc profile provided by the ICC, to map the original sRGB values into CIELAB that is inside the PRMG gamut. However, all those colors inside the PRMG and outside our printer will get clipped to the printer's gamut, losing the details in the dark tones. However, I am not aware (have not shopped for a while) of commercial profile generators that, on top of claiming V4 compliance, implement proper v4 behavior and certain level of intelligence in the gamut mapping directed towards exploting the printer's gamut. I am not sure if colprof would be able to generate an output profile that has a PCS gamut similar to PRMG and then a 'progressive' gamut mapping into the printer gamut. On the other hand, it would be enough if we could obtain such a behavior in a device link built with collink. Is this possible?
