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: Examples relate to a method to generate a user print mode. The method comprises selecting a predetermined print mode, setting a user level of treatment fluid different to a predetermined level of treatment fluid of the predetermined print mode, obtaining a plurality of color profiles for a plurality of levels of treatment fluid, generating a user color profile based on the obtained plurality of color profiles and replacing the color profile of the selected predetermined print mode by the generated user color profile to generate the user print mode for the set user level of treatment fluid.

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.
