A method of selecting optimal inks from a plurality of ink candidates for a given colour, said method comprising a) obtaining a measure of spectral reflectance of a print substrate; b) obtaining a measure of the spectral reflectance of a first candidate ink of a first colour; c) predicting a colour gamut for the first candidate ink based on the spectral reflectance of the ink and the spectral reflectance of the substrate; d) repeating steps b) and c) for a second ink candidate of the first colour; e) selecting the ink candidate for which the predicted colour gamut includes the most target spot colours as the optimal ink for the first colour. |
