Abstract

A method is proposed for generating a color profile using the determination of a mapping A′ of a device-independent process space Q(m) of dimension m, m being a natural number, to a device-dependent process space K′(n) of dimension n, n being a natural number, for a first set of specific parameters, which is distinguished by the mapping being represented by a concatenation of mappings, which includes a known mapping A from Q(m) to a device-dependent process space K(n) of dimension n, n being a natural number, for another set of specific process parameters, which differs at least in one element from a first set of specific process parameters; and either of a mapping TK from K(n) to K′(n) or a self-mapping TQ by Q(m).
