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.
