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.
Claims20
A system comprising:
- a color sensor to determine color of color patches printed on a substrate;
- a substrate support for supporting the substrate during operation of the color sensor, the substrate support including:
- projections extending from a base of the substrate support and arranged to support the substrate, and
- openings to allow deformation of the substrate towards the base;
- a distance sensor to measure a distance indicative of a distance between the color sensor and the substrate;
- and
- a controller to:
- determine, using the distance measured by the distance sensor, a location of a given projection of the projections, and
- determine a color of a color patch on the substrate at the determined location of the given projection.
A non-transitory computer readable storage medium storing instructions that upon execution cause a printing system to:
- position a substrate on a substrate support including:
- projections extending from a base of the substrate support and arranged to support the substrate, and
- openings to allow deformation of the substrate towards the base;
- receive, from a distance sensor, a measured distance indicative of a distance between a color sensor and the substrate;
- determine, using the measured distance, a location of a given projection of the projections;
- and
- determine a color of a color patch on the substrate at the determined location of the given projection.
A method comprising:
- printing a test pattern on a substrate, the test pattern including a plurality of color patches;
- positioning the substrate printed with the test pattern on a substrate support including
- projections extending from a base of the substrate support, the projections arranged to support the substrate, and
- openings between the projections to allow deformation of the substrate towards the support base,
- receiving, from a distance sensor, a measured distance indicative of a distance between a color sensor and the substrate;
- determining, by a controller using the measured distance, a location of a given projection of the projections;
- and
- determining, by the controller, a color of a color patch on the substrate at the determined location of the given projection.
