Gary, I've been following this thread for a while and I think you are getting into the "color management" swamp. I've spent a few years untangling this for myself and suggest as a starter reading ""Real World Color Management" by Bruce Fraser et al. For myself, it took about five readings to understand what I didn't know. It begins with calibration and profiling of the monitor with a dedicated colorimeter or spectrphotometer and then entering into the morass of printer/paper profiling. Color management in Linux is not as unified as in Windows or Mac and am unsure about Linux software to interface monitor calibration hardware. I have had to spend about $2000 to get results from the monitor to approach what I print.
