    Abstract: A printer apparatus comprises one or more ports (2011 to 201M) for receiving one or more colorant units (INK1 to INKN), and a processing unit. The processing unit is adapted to determine which one or more colorant units (INK1 to INKN) have been loaded into the printer apparatus. The processing unit is adapted to retrieve colorant information from each loaded colorant unit (INK1 to INKN), and determine an ink-set configuration using the colorant information retrieved from each loaded colorant unit (INK1 to INKN). Operation of the printer apparatus is configured according to the determined colorant-set configuration.

    Abstract: In example implementations, a method is provided. The method determines relative colorant volumes to colorimetry relationship of first substrate at first time. Determine relative colorant volumes to colorimetry relationship of first substrate at second time as function of relative colorant volumes to colorimetry relationship of first substrate at first time. Determine ratio of relative colorant volumes of first substrate at first time and second time. Determine relative colorant volumes to colorimetry relationship of second substrate at third time as function of ratio of relative colorant volumes of first substrate. Determine relative colorant volumes to colorimetry relationship of second substrate at fourth time as function of relative colorant volumes to colorimetry relationship of second substrate at third time. Compensate colorant drift on second substrate based on difference between relative colorant volumes to colorimetry relationship of second substrate at third time and fourth time. Compensate colorant drift on the first substrate.

    Abstract: Certain examples described herein relate to a color processing apparatus and a method of generating configuration data for a color rendering device. The color rendering device operates based on color state instructions indicating output color states for portions of a rendered output. Render data may be generated by applying a halftone matrix and color data may indicate probability values for the output color states for input image areas corresponding to the portions of the rendered output. In described examples, configuration data defines an order of output color states for application of the halftone matrix. In the order, the output color states are grouped within the data based on color properties of a rendered output and an order within the clusters is based on colorant composition.

    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.
