Abstract: Certain examples described herein relate to color spaces. In some cases, data representing a set of color values is obtained. Each color value has, for each of first, second and third axes defining a three-dimensional color space, a respective coordinate value. In some cases, for each of the set of color values, the coordinate value for the first and/or second axis is transformed dependent on the coordinate value for the third axis, to generate data representing a transformed set of color values. A set of output color values in an output color space is derived using the generated data. Output data associating the set of output color values in the output color space with a set of further color values in a further color space is generated.

Abstract: In an example, a method includes receiving, at a processor, a first matrix comprising a set of print coverage vectors, each print coverage vector specifying print materials for object generation using additive manufacturing and a second matrix comprising a corresponding set of properties for objects generated using the print coverage vectors. The method may further include determining, by the processor, a solution to an objective function relating the first and second matrices.

Abstract: In some examples, a plurality of print material combinations for object generation are determined, each print material combination having an associated color. A plurality of color descriptions may be determined, the color descriptions corresponding to a combination of voxels, each of the voxels of the combination of voxels having a defined print material combination and a defined depth with respect to a surface. A color mapping resource may be defined, the color mapping resource associating a color description with a print instruction, each print instruction being for use in causing an object generation apparatus to generate the combination of voxels corresponding to the associated color description.

Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises object property data indicative of properties of the three-dimensional object. Layers within the three-dimensional object to be printed are identified. The obtained data is processed by comparing object property data associated with an identified layer to object property data associated with a reference layer selected from the identified layers. Where a difference in object property data associated with an identified layer and object property data associated with a reference layer is determined, the determined difference is stored.

Abstract: Methods and apparatus associated with three-dimensional objects are described. In an example, a method comprises receiving data representing a three-dimensional model object, the data comprising object model data and object property data. For at least one object property, a sub-region of the object in which the object property is non-variable is identified and, for at least one location within the object, all sub-regions in which the location is situated are identified. Based on the combination of identified sub-regions for a location, print material data is determined for the location. Control data for the production of a three-dimensional object is generated according to the print material data.

Abstract: Defining color separation for printing an image is disclosed. A color separation model is created. The model comprises a separation hypercube, wherein each axis of the separation hypercube represents a metric of the printing process and each vertex of the separation hypercube at each end of each axis represents the optimized separation of each metric. A weighting for at least one of the metrics represented by the created color separation model is determined. The determined weighting is applied to each of the vertices of the created color separation model to determine new vertices. A new color separation model based on the determined new vertices is created.

Abstract: Certain examples described herein relate to the control of colorants and treatments for printing. In certain examples image data, a colorant color mapping and one or more treatment color mappings is obtained. The colorant color mapping may be used to map the image data to colorant application values. The one or more treatment color mappings may be used to map the image data to treatment application values. The colorant application values and treatment application values may be used to generate discrete print control instructions to apply the set of colorants and set of treatments to a printing substrate.

Abstract: Disclosed is a non-transitory computer readable storage medium, a computer-implemented method and an imaging color profile of an imaging apparatus. A processor retrieves the color profile of the imaging apparatus from data storage, the color profile comprising a first plurality of associations between a first plurality of color values in a first color space and a second plurality of color values in a second color space. The processor receives input data indicating a determined association, the determined association being an association between a first determined color value in the first color space and a second determined color value in the second color space. The processor performs an update process to update the first plurality of associations, the update process comprising performing an interpolation process using the determined association and an association of the first plurality of associations.
