Abstract: In some examples, a system receives a color sample comprising a color measurement of a proper subset of a gamut of colors printable by a printer, and computes a forward transform value and a reverse transform value based on a color profile calculated from a profiling chart comprising a set of estimated color samples calculated based on the received color sample, the forward and reverse transform values to convert between colorimetry values and color values for the printer. The system provides an adjusted color profile for the printer based on an original color profile for the printer and the computing, wherein the original color profile for the printer is associated with a substrate.

Abstract: A method is described in which sets of corresponding colorimetric values are obtained. In a set, a colorimetric value is associated with a device color. A number of device colors are selected according to the color differences between colorimetric values associated with the same device color. A color calibration pattern is elaborated for a printer to be calibrated using the selected device colors and calibration is performed using the sets of colorimetric values.

Abstract: From a statistical distribution of different color states in an image subdivided in pixels, pixel color states are selected by performing comparisons between predetermined values and values associated to per-pixel state probabilities. Errors (based on drifts between selected color states and per-pixel state probabilities) are diffused to per-pixel state probabilities of subsequent pixels.

Abstract: In some examples, a system generates three-dimensional (3D) object data for printing by a 3D printing system, the generating including determining a region in which to generate a wear indicator, and computing an arrangement of spatial shells of variable thickness in the region, where the spatial shells contain data representing at least one property of the wear indicator.

Abstract: A method of processing data in a multi-stage imaging pipeline, the method comprising, at each stage of the multi-stage imaging pipeline, identifying a plurality of encoding values represented in received input data in a given encoding space for the respective pipeline stage, the identified plurality of encoding values comprising a subset of encoded values which are capable of being represented in the given encoding space, generating a list of encoding indices corresponding to the identified plurality of encoded values in the given encoding space, representing the encodings of one or more entities of the received input data using the generated list of encoding indices, and outputting the represented encodings of the one or more entities to the next stage of the multi-stage imaging pipeline.

Abstract: In an example, a method includes characterising, using at least one computer, an initial gamut from an initial set of color mappings from a source color space to a printing device color space. The method may further include characterising, using at least one computer, an initial gamut from an initial set of color mappings from a source color space to a printing device color space. The method may further include characterising, using the at least one computer, a printing device color gamut. The method may further include transforming, using the at least one computer, the initial set of color mappings to form a transformed set of color mappings mapping from the source color space to the printing device color gamut.

Abstract: In some examples, octree serialization can include non-transitory machine-readable medium storing instructions, the instructions executable by a processing resource to evaluate two or more nodes sequentially in an octree structure until a leaf node is reached, wherein the two or more nodes include at least one non-leaf node, and generate a serialized octree document based on a respective node identifier in a header associated with each node of the two or more nodes.

Abstract: A method for color mapping is disclosed. A color mapping is generated based on an imaging model and a color model for an imaging device. The imaging model allows a set of perturbations to be modelled. A set of metamers is determined for one or more colors. For each metamer, at least the imaging model is used to estimate a color output with at least one modelled perturbation. The color outputs are used to select a metamer from the set to be used for the color mapping.
