Abstract (en)
[origin: WO2004015380A1] The invention relates to an evaluation method consisting in representing the pigment combination (B, W, C1 and C2) in the form of a volume in a standardised colorimetric space (Lab) and voxelising said volume. According to the invention, all of the resulting occupied voxels correspond to all of the hues that can be obtained from said pigment combination and each occupied voxel (V2) corresponds to a determined proportion between the constituent pigments (B, W, Cl and C2).
