    Abstract: To bring color, described by Lab values only, back into the spectral domain the invention discloses a method for automatically generating reflectance spectrum values from tristimulus values using a computer system administrating a database with data matrices of reflectance spectra of different colors differentiated by at least the process parameters print technology, substrate and print order of inks, wherein a) given tristimulus values of a color are classified with regard to the process parameters, b) in the database the data matrices of reflectance spectra of the respective color with the most matching process parameters are identified and c) the identified data matrix is used to define the reflectance spectrum values for the respective color.
