    摘要： A printer is configured to print a color target that associates colors to which humans are most sensitive to color variance with areas of the color target within which color measurement is less prone to meassurement error. The printer then prints the color target according to the association. In an optional impemementation, measurements of like color elements within the target are average. In a further optional impementation, the averaging is performed using weighted values, wherein the weighting is based on color measurement accuracy within an area within the color target wherein each measured element is located. In a still further implementation, a color look-up table is generated according to measurements made of the color target.

    摘要翻译： 打印机被配置为打印将人类最敏感的颜色与颜色偏差相关联的颜色目标，颜色对象的颜色测量不太容易发生测量误差的区域。 然后打印机根据关联打印颜色目标。 在可选的重建中，目标内的相似颜色元素的测量是平均的。 在进一步可选的折叠中，使用加权值执行平均，其中加权基于颜色目标内的每个测量元件所在的区域内的颜色测量精度。 在另一实施方式中，根据由颜色目标进行的测量产生颜色查找表。

    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： 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.
