    摘要： A look-up table for use in a printing system is created. The printing system prints an input image in a print color space. The look-up table is created by accessing a predetermined look-up table representing a mapping of color values of an input color space to ink-vectors of a print color space; applying a p-by-q halftone threshold matrix to each ink-vector of the predetermined look-up table to generate a p-by-q halftone cell for each ink-vector; and creating a further look-up table which maps, at least a sample of, the color values of input color space to the at least one halftone cell.

    摘要： A method for printing with a printhead, comprising: generating a first imaging matrix comprising cells each containing information related to the ink to be deposited on a corresponding area of the print medium; on the basis of said first matrix, generating a second imaging matrix, comprising cells each containing information related to the ink drops to be deposited on a corresponding area of the print medium; wherein some cells of the second matrix are prioritized and for some of them the information related to the ink drops depends on a cell of the first matrix that corresponds to a different area of the print medium than the area of said prioritized cell of the second matrix; such that upon printing, nozzles of the printhead associated with some prioritized cells fire ink that in the first matrix is associated with areas of the print medium corresponding to non-prioritized cells.

    摘要： Method of determining a color gamut of a predetermined print system, comprising determining ink restrictions of the print system, generating all NP states of the print system, generating a convex hull of area coverages of NPs that do not exceed said ink restrictions, determining which NP states are outside of the convex hull, mapping NP states that are outside of the convex hull onto the convex hull, re-expressing the mapped NP states as area coverages of NPs, and sampling the convex hull in a colorimetrically predetermined way.

    摘要： In an example, a method for generating control data for production of a three-dimensional object is described. A model of the three-dimensional object is obtained as a array of voxels, and it is determined for each voxel whether that voxel comprises part of a first or a second sub-object of the three-dimensional object. Each first sub-object voxel is mapped to a volume coverage representation defining print material data for that voxel. The second sub-object voxels are mapped to a volume coverage representation defining common print material data for the voxels of second sub-object. Control data for printing the first sub-object is generated from the print material data for that voxel common print material data for the Control data for printing the second sub-object is generated according to the volume coverage representation for the second sub-object.
