Abstract: Example implementations relate to color compensation. Some examples may print a calibration target background on a non-opaque media. The calibration target background may have a color that increases a dynamic range of a set of color measurements of a calibration target foreground. Some examples may print the calibration target foreground over the calibration target background. Additionally, some examples may measure an optical density of the calibration target foreground with a reflective sensor and may calibrate a printer based on the measured optical density.

Abstract: Techniques related to printer calibration are disclosed herein. In an example, an actual measurement of a colorimetric parameter is performed by measuring the colorimetric parameter on a printed calibration pattern. The colorimetric parameter is associated with an ink drop number. The calibration pattern is printed with selected printing conditions. An ink drop number variation is determined from a reference measurement and the actual measurement of the colorimetric parameter. The reference measurement is a measurement of a colorimetric parameter. The reference measurement corresponds to a measurement of the colorimetric parameter on a calibration pattern printed with the selected printing conditions. An actual linearization is generated by validating a set of pre-defined linearizations with the determined ink drop number variation. Other examples of printer calibration are disclosed.

Abstract: A measured distance is received from a distance sensor, where the measured distance is indicative of a distance between a color sensor and a substrate. Using the measured distance, a location of a given projection of projections of a substrate support is determined. A color of a color patch on the substrate at the determined location of the given projection is determined.
