    Abstract: A computing device receives first data indicating a first metric of a first printed test area and second data indicating a second metric of a second printed test area. The first printed test area is associated with a first plurality of Neugebauer Primaries and each Neugebauer Primary in the first plurality of Neugebauer Primaries is associated with a respective area coverage in the first printed test area. The second printed test area is associated with a second plurality of Neugebauer Primaries, wherein each Neugebauer Primary in the second plurality of Neugebauer Primaries is associated with a respective area coverage in the second printed test area and the second plurality of Neugebauer Primaries is different from the first plurality of Neugebauer Primaries. The computing device generates third data associating a color in a color space with the first plurality of Neugebauer Primaries or the second plurality of Neugebauer Primaries in dependence on the first metric and the second metric.

    Abstract: A method of obtaining a calibration factor for color calibration of a printing system. The method includes printing, using the printing system, a plurality of Neugebauer primaries (NPs) each defined by a respective Neugebauer primary area coverage (NPac) vector. For each of the NPs, an area coverage change of the NP is determined from a measurement of a visual property for the NP and a measurement of the visual property for a corresponding reference NP corresponding to the respective NPac vector. The calibration N factor for the printing system is obtained based on the area coverage change for respective NPs of the plurality of NPs.

    Abstract: Certain examples relate to configuring a print processing system to produce rendered color outputs based on desired properties of said outputs using resources available to the print processing system. In these examples, print job data is received comprising image data and print property data. Color mapping data is configured to produce print mapping data based on at least the print property data. Print instructions for an image rendering device are generated based on the print mapping data. The print properties may be selectable by a user. Color mapping data may be characterized by color properties.

    Abstract: Certain examples described herein relate to mapping between an input color space and an output color space. In some cases, data representing a set of candidate output color values in the output color space is obtained for a transition region between two input color values in the input color space. A sub-region of the transition region is defined, the sub-region being associated with a target colorimetry and a target value of a metric. An output color value is selected from the set of candidate output color values. The output value has an associated value of the metric and an associated colorimetry. The selecting is based on the associated colorimetry and the target colorimetry, and the value of the metric and the target value of the metric. In some cases, mapping data is generated by assigning the selected output color value to the sub-region.
