How reddish is reddish? If its a major cast, then there is something wrong,
such as another application loading a startup item, or some other incorrect
setting, or barring all that, perhaps even a bad Spyder. ColorVision tech
support should be able to assist you in determining which of these. If its a
minor difference when comparing your output to screen, and you find it
convenient to tweek this in the monitor profile instead of the print
profile's preview, then what you are doing would be an appropriate
workaround; keeping in mind its a hack, not a universal correction.
