Abstract: A colorant splitting method performed by a colorant splitter wherein an n-dimensional colour in an n-dimensional colorant space is converted to an m-dimensional colorant space by a colorant splitting curve set and wherein the colorant splitting curve set is the result of interpolation of a set of colorant splitting curve sets to improve the image quality of reproduced content and to improve the usage of total coverage of the colorants.

Abstract: A method including the steps of selecting an n-ink model for a color device, for transferring a set of colorant values in colorant space to a set of color values in color space; selecting a printer characteristic of the n-ink model, wherein the printer characteristic indicates the regularity of the n-ink model; evaluating, for the n-ink model, a set of one or more values and/or ranges for the printer characteristic, thus determining the regularity of the n-ink model; and modifying the n-ink model such that the modified n-ink model is regular, if, based on the evaluation, the n-ink model was not regular.

Abstract: A standard printer characterization target is printed with a reference printer and measured. From the measured data, a model is derived that describes for each ink the behavior of each individual ink in combination with different combinations of the other inks. In order to reduce the complexity for obtaining a printer model of a second printer, a second target is printed that includes only a subset of the color patches in the standard printer characterization target. With the model and interpolation, it is possible to reconstruct colorimetric data for missing color patches in the reduced target.
