When designing for print, a common issue that has to be dealt with is the difference between the color on your computer display and on paper. Even if your monitor is calibrated correctly the match them as best as possible, your clients will not be, and so a third version of the color comes into play. If you then print proofs for your client on any printer other than the one that will be used for the final job (which is often the case), more colors join the mix that wont match the final piece.
