This is an extreme example of bad color management practice or lack thereof. Hopefully, most users operate under some decent default color space such as sRGB. But other than this extreme example, I personally never seen a case where a monitor profile could be used in a color conversion as the Source. They are meant to be used as the Destination, not the Source.

Monitor profile can be source of conversion in cases when the image painted or edited directly in the monitor color space. For example, the results of creative work at a workstation without any color management. They will be straight into the monitor color space. In such cases the RGB numbers of the image represents directly the monitor color space in which the image was created or edited. So, to bring such images to standard or just to print them correctly, You should use certain monitor ICC profile as source in conversion chain. If You've got an artwork and the display of painter workstation wasn't profiled and was far from standard, the artwork appearance on painter display and on Your display will be different. You will be unable to view or print the artwork correctly. In this case You can initiate the profiling of the painter display (without display calibration and tuning). After the profiling You can assign the profile to already obtained artworks and get the same color as the painter saw. Sat, 31 Mar 2012 20:02:44 +0200 от Mauro Boscarol <mauro@xxxxxxxxxxxx>: Hi all. I have a general question: In which cases the ICC profile of a monitor is used as the source of a color conversion? For monitor compensation and soft proof the monitor profile is used as destination. There are typical cases in which the monitor profile is used as the conversion source? Thank you. Mauro Boscarol
