Abstract
Method of computing a convex hull in a predetermined color space, comprising determining a print attribute value range pertaining to a reference print attribute value, selecting base NP (Neugebauer Primary) area coverages, comprising area coverages of single NPs and combined NPs, having print attribute values in the print attribute value range, printing and measuring patches corresponding to the base NP area coverages, computing linear combinations of the base NP area coverages, and assigning one of the base NP area coverage or the linear combination of base NP area coverages to the corresponding color, depending on which is closest to the reference print attribute value.
