No currently X is not color management aware. > That would presumably correct my display system and make all output of > any image "correct" regardless of the tool used.

All you need to do is convert the image from the images current color space into the printer color space before sending it to the printer. The hard part is getting a valid printer profile. > > Anyway, I'm sure I need much information from other places, but this > seems like a list that probably has the wisest and most broadly > educated folks on it, so I was hoping to get some early pointers.

Profiling makes the assumption that everything in the processing chain of an image is identical. In this case the Windowing systems and the video card drivers are different. The profile is likely not totally correct even if you use a gamma loader to load the VCGT data. But it may be closer than not having a profile at all or using a "visual input" type profile (like those created with AdobeGamma). > > Does that make more sense as a question?
