    Abstract: A pixel source for a visual presentation is disclosed. The pixel source can include a light source, a large gamut pixel, a subtractive mask, and a control input to control the subtractive mask. A display device is also disclosed comprising a light source array with a large gamut pixel array and subtractive mask array disposed thereon. In operation, wide-band light emitted from each light source can be modulated by each large gamut pixel to output a plurality of primary colors. Each subtractive mask can be controlled to block, partially transmit, or fully transmit any number of the outputted primary colors to produce color points that can be interpolated and half-toned to output a large gamut of secondaries for each pixel.

    Abstract: An example computer-implemented method of generating a pattern of thresholds for halftone printing of an image is disclosed. The halftone pattern is generated by an analytical computation of threshold values in-situ using a quasicrystal function. Each halftone pattern produced is non-periodic yet possesses ordered character where the pattern does not line up perfectly with a shifted copy of itself. The generation of such halftone patterns is suited to applications where a single halftone threshold value may be used per pixel.

    Abstract: Certain examples relate to a method of a method of printing an image which comprises determining image data for an image to be printed onto a substrate, the image data comprising application amounts of one or more colorants to be applied to the substrate. A print mode is determined for applying the colorants to the substrate and comprises a plurality of application passes each for applying some of the application amounts of the colorants to the substrate and a drying delay between at least some of the application passes. The duration of the drying delay is dependent on a characteristic of one or more of the colorants or substrate. The image is printed using the image data and the print mode.

    Abstract: In an example, a method includes determining, using processing circuitry, a first print coverage vector associated with an estimated colorimetry which corresponds to a target colorimetry, wherein the estimated colorimetry of the print coverage vector is based on a first color model, the first print coverage vector being optimised relative to a first metric. The method may further include determining, using processing circuitry, a predicted colorimetry of the first print coverage vector based on a second color model.

    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.
