I appreciate the follow up to my earlier comments. I wanted to add that like the white balance setting a camera uses to adjust for different lighting conditions, printing paper and their cooresponding inks are design to be viewed under certain conditions. If one views paper whiteness in a dark room or under florescent lights, the viewer's perception of that color will be different than if viewed under controlled conditions such as found in a 5000K light booth. The transparent printing ink filters light reflected off the paper, therefore unless the print is viewed under light similar to that which the monitor was calibrated to match, the print will not reflect (literally!) an accurate representation of the calibration process.
Of course, viewing paper or a test print in the bright, sunlight, conditions of a 5000K color adjusted light while working on a monitor, that is best viewed in a darkened room, is extremely difficult and for these reasons color calibration hardware and professional quality monitors are popular in the professional color reproduction industry.
Edited to add: I should clarify, for those knowledgeable or seeking more knowledge, that my earlier post used the term "reflective" to describe the color system that printing entails. This is not entirely accurate and should have been described as a "subtractive color system". The ink on paper acts as a filter which "subtracts" certain colors from the visual spectrum allowing only the shade of each color in a spectrum of white to be transfer back to the viewer.
