Abstract
Techniques related to color analysis are disclosed herein. In an example, substrate locations on a printed pattern are selected based on a set of measurements related to substrate-height. Further, color of the printed pattern is determined at the selected locations.
Claims25
A printing system for printing on a substrate, comprising:
- a first sensor for providing output associated with vertical positions of respective substrate locations on the substrate;
- a color sensor for providing a color output signal associated with color of a pattern printed on the substrate;
- a location engine configured to select a location on the pattern from among the substrate locations, based on the output from the first sensor, the selecting based on a determination by the location engine that the output from the first sensor indicates that the vertical position of the selected location is within a selected range;
- and
- a color acquisition engine configured to determine a color of the printed pattern at the selected location from the color output signal of the color sensor.
2 more elements
A non-transitory computer readable storage medium comprising instructions that, when executed by a processor, cause the processor to:
- receive measurements associated with vertical positions of substrate locations across a substrate;
- select, from among the substrate locations, a sample location on a color patch printed on the substrate, the selecting comprising identifying, based on the received measurements, at least one of the substrate locations that is associated with a vertical position within a selected range;
- and
- determine a color of the color patch at the selected sample location.
1 more element
A color analysis method comprising:
- acquiring a set of measurements by a sensor across a substrate including a printed pattern, the set of measurements being indicative of vertical positions of respective substrate locations across the substrate;
- selecting, by a system including a processor, a substrate location from among the substrate locations on the printed pattern based on the set of measurements, the selecting comprising identifying, based on the set of measurements, a substrate location that is associated with a vertical position within a selected range;
- and
- determining, by the system, a color of the printed pattern at the selected substrate location.
