Abstract: Methods and apparatus for developing a color mapping for mapping colors from a source gamut to an output gamut are described. In an example, defects in a printed output image are used to identify a region of an initial output gamut associated with a defect. A modified output gamut may be developed, the modified output gamut excluding the identified region. A color mapping for use in mapping colors from the source gamut to the modified output color gamut for producing an output image may also be developed.

Abstract: A method of applying a cap to a printhead may comprise selectively applying an immiscible fluid to a surface of a printhead in which the immiscible fluid caps a number of nozzles on a number of nozzles defined within the printhead. A printhead may comprise a layer of immiscible fluid in which the immiscible fluid is selectively applied to the surface of the printhead and in which the immiscible fluid caps a number of nozzles defined within the printhead. A printer may comprise a printhead comprising a number of nozzles, an immiscible fluid applicator, and a processor to instruction the immiscible fluid applicator to apply a layer of immiscible fluid to the surface of the printhead.

Abstract: An example method for constructing a three-dimensional object in accordance with aspects of the present disclosure includes projecting an image of a section of a three-dimensional object on a building plane through a projection unit, forming a cured section by irradiating laterally an interface of a photopolymerizable material on the building plane with light corresponding to the image of the section of the three-dimensional object, moving a support plane laterally to detach the cured section from the building plane resulting in a gap between the cured section and the building plane, and filling the gap between the cured section and the building plane with photopolymerizable material.

Abstract: A printhead service station comprises a printhead cleaner, a motor to move the printhead cleaner along a first direction during a printhead cleaning operation, and a spitroller to catch waste printing liquid during printhead cleaning. Therein, an axis of rotation of the spitroller is oriented substantially parallel to the first direction, and a rotation of the spitroller is driven by the motor.
