To improve a method for making an overprint prediction to that extent, that the method allows more reliable overprint predictions with a reduced effort, the invention proposes a method for making the overprint prediction for a color combination, in which method a printing substrate and at least two printing colors and one gradation of hue values per printing color including the full tone as well as color combinations are predefined as data of the hue value of the n printing colors, wherein first of all individual color predictions comprising three transmittance components and the associated transmittance spectra for the respective hue value are determined for each of the n printing colors, wherein for an intended color combination up to (3 to the power of n) combinations of the transmittance components and the associated combined transmittance spectra are determined, and an overall reflectance spectrum of an overprint is predicted on the basis of the determined transmittance components with their transmittance spectra and the reflectance spectrum of the unprinted substrate.
