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 first input color channel value for a first colorant and a second input color channel value for a second colorant are received. A first number of drops of a first colorant is obtained based on the first input color channel value and a first drop sequence. A second number of drops of a second colorant is obtained based on the second input color channel value and a second drop sequence. The first drop sequence defines a first mapping between input color channel values and number of drops and the second drop sequence defines a second, different, mapping between input color channel values and number of drops.

Abstract: A method for assessing color performance in a printing device, which is provided with color printing means for printing at least three primary color inks, comprises the steps of: (a) providing a printing file for printing at least one color scale, said scale comprising: a plurality of colored regions defined by substantially equal amounts of a first primary color ink and of a second primary color ink and a variable amount of a third primary color ink, said amount of third primary color ink increasing progressively from each region to the adjacent region in one direction of the scale, and a transition region defined by substantially equal amounts of the three primary color inks; (b) printing said printing file with said printing device to obtain a printed color scale; and (c) visually analysing the printed color scale to assess the performance of said color printing means for printing said third primary color ink, on the basis of the position of the transition region along the color scale.

Abstract: A system and method for modifying print settings for a processed file is disclosed. An application generates a file to printed by a printing device. A print settings software is configured to modify print settings in the generated file prior to the file being printed. The print settings software generates a display of print settings that may be modified by a user. The user selects print settings, and the print settings software modifies a header file to include the user-selected print settings. The file is then printed with the user-selected print settings.
