Abstract: It is made possible to perform appropriate color matching between devices irrespective of whether a printed material is print-output in color or monochrome from a destination device. The color characteristic of the destination device is obtained by printing a chart in which a predetermined density pattern is formed in the destination device and reading the color of the chart. Next, whether the chart output from the destination device is color or monochrome is determined. Then, color conversion parameters for reproducing the color characteristic of the destination device in an adjustment device are determined by printing the color chart in a case where the printed material is determined that formed in color or printing the monochrome chart in a case where the printed material is determined that formed in monochrome in the adjustment device.

Abstract: A computer-implemented method is provided for dosing ink in a digital printing device with multiple ink channels, when printing on a reflective substrate. A digital printing system configured with the method is also provided. Target color data of a target color to be printed on the reflective substrate is captured, including both color data and spectral reflectance data. The captured color data is processed with a printer model to output a preliminary dosing ratio for each ink channel. A digital opacity value for the target color is computed from the dosing ratio of each ink channel. A natural opacity value for the for the target color is computed from the captured spectral reflectance data, and a difference between the digital and natural opacity values is calculated. A predicted dosing ratio for each ink channel is obtained by interpolating the difference against an ink step of a diffuse ink component of the target color.

Abstract: A method for correcting tone-level non-uniformities in a digital printing system includes printing a test target having a set of uniform test patches. The printed test target is automatically analyzed to determine tone-level errors as a function of cross-track position for each of the test patches. A tone-level correction function is determined and represented using a set of one-dimensional feature vectors which specifies tone-level corrections as a function of cross-track position, pixel value and time. Corrected image data is determined by using the tone-level correction function to determine a tone-level correction value for each image pixel responsive to the input pixel value, cross-track position and time. The corrected image data is printed using the digital printing system to provide a printed image with reduced tone-level errors.

Abstract: Certain examples described herein relate to adjusting a printing system. In certain cases, a lookup table, LUT, is obtained where the lookup table comprises a plurality of nodes that map a plurality of input first color space values to a plurality of Neugebauer Primary area coverage, NPac, vectors in a second color space and each NPac vector comprises at least one Neugebauer Primary, NP. Each NPac vector in the LUT is adjusted by the determination of a colorimetric value of the NPac vector and the modification of the NPac vector based on a characteristic of the corresponding at least one NP and the colorimetric value such that the modification is specific to the NPac vector. The lookup table is updated with the modified NPac vector and stored for referral by the printing system in any future printing.

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.
