Certain examples described herein relate to generating a color mapping between a source color gamut within a source color space and a target color gamut within a target color space. Gamuts may be set based on a color rendering device. In examples, a sequence of forward color transformations that transform the source color gamut is defined, along with a sequence of inverse color transformations that transform the target color gamut. A gamut mapping is applied between the output of the forward color transformations and the output of the inverse color transformations, wherein the color mapping is usable by a computing device to map between the source and target color spaces.

A method for color mapping is disclosed based on obtaining a measurement of one or more characteristics of an imaging system. A set of color mappings are provided and the color mapping is selected based on the measurement. Each of the color mappings enables a mapping from a first color space to Neugebauer Primary area coverage vector space. A method for generating a color mapping is disclosed.

A data processing method, a system and a user interface are disclosed, for dosing ink in a digital printer with at least 6 ink channels. A forward transformation model is obtained or computed for defining a relationship between coordinates of device-dependent ink values across the ink channels and coordinates of device-independent colorimetric values in a color space. An inverse model of the forward transformation model is computed, wherein the inverse model comprises an adjustable constraint on each ink channel. One or more constraints are applied to each ink channel with predetermined and/or user-defined value(s). A target colorimetric value is input to the inverse model. An ink value is computed for each ink channel with the inverse model, wherein each computed ink value corresponds to ink dosage in its respective ink channel and the computed ink values collectively correspond substantially to the target colorimetric value.
