Abstract: A system in accordance with an example is to assign a display color to a pixel to be displayed, to achieve an apparent desired color at a local neighborhood node of pixels having an apparent color bit depth greater than an addressable color palette for the display color that the pixel is capable of producing. The display color is assigned to the pixel based on a convex combination of colors of the local neighborhood node of pixels, to provide the desired color for the node based on local optical averaging.

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: A method in described in which a halftone matrix is generated using a kernel by mapping kernel values of each pixel to a halftone matrix value at a corresponding element of the halftone matrix. Where a plurality of pixels have the same kernel value, the kernel value is randomly mapped to a respective halftone matrix value in a range of halftone matrix values corresponding to the kernel value.

Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises sub-volumes representing the three-dimensional object. A characteristic for the three-dimensional object to be printed is identified. Based on the identified characteristic, property data is set for individual sub-volumes to be used in printing the three-dimensional object. The identified characteristic is a function of the property data. The property data comprises material property data, structural property data and printing property data.

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: In an example, a method includes receiving, at a processor, a plurality of property parameter sets representing attainable property combinations in additive manufacturing and being associated with print material description. A constraint of a first property of the property parameter sets may also be received and a hull of a property mapping resource for use in determining additive manufacturing instructions for generating an object in which the first property meets the received constraint may be determined.

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.
