Abstract: A method is disclosed. According to some examples, the method comprises determining, by processing circuitry, a first element set to be associated with a print addressable location, the first element set comprising a first plurality of elements, wherein each element of the first plurality of elements identifies a print colorant or print colorant combination and is associated with a probability that the print colorant or print colorant combination identified by that element is to be applied to the associated print addressable location. The method may comprise determining, by processing circuitry, a second element set to be associated with the print addressable location, the second element set comprising a second plurality of elements, wherein each element of the second plurality of elements identifies a print agent or print agent combination and is associated with a probability that the print agent or print agent combination identified by that element is to be applied to the associated print addressable location. The method may comprise determining, by processing circuitry, a combined element set based on the first element set and the second element set. An apparatus and a machine-readable medium are also disclosed.

Abstract: In an example, a method includes receiving, at a printing apparatus, a print target. The method may also include printing a drop linearization chart on a sample of the print target and measuring the drop linearization chart to determine a measured drop linearization curve for the print target. The method may include comparing the measured drop linearization curve to a plurality of predefined drop linearization curves to determine a most similar drop linearization curve from the plurality of predefined drop linearization curves, and applying a linearization defined by the most similar drop linearization curve to print data to be printed on the print target.

Abstract: A color management method is disclosed. The method comprises printing, on a first side of a separating medium, a plurality of color regions, each region being of a different color of a set of colors; printing, on a second side of the separating medium, for each of the plurality of color regions, a plurality of patches within an area registered with a respective color region, wherein each patch has a different one of the set of colors; and generating, for each of the plurality of color regions, an international color consortium (ICC) profile by characterizing each color region using a spectrophotometer. A machine-readable medium and an apparatus are also disclosed.
