I think you are talking about how to know what the color saturation will look like when you print directly on your disk with your inkjet printer. If I understand your problem, the absorption and reflectivity of paper is different, and therefore a test print doesn't accurately show what is going to happen when you print directly on the disk.

The usual way to handle this is to create color profiles for each media. If you search for "Windows ICC color profiles" in Google, you should come up with sites that describe how to do this calibration process. It usually involves printing a test, and then scanning the result (with a flatbed scanner). This should not only help to better match your monitor with your output, but it should also help the output to your various media look better. Remember, however, that you must have a different profile for printing to the disk than printing to paper. Also, you can never make the paper and disk look identical, because each media has different absorption and reflectivity characteristics. Finally, you can never reproduce the same range of colors on any two devices. Each device (printer) has a different "gamut" of color, and this gamut can be further restricted depending on the media to which you print.
