Abstract
Systems and methods for utilizing metadata embedded in a color measurement target to uniquely identify the target through color measurement. A color measurement target is used for color calibration, color characterization, color adjustment and/or color correction of a color output device and includes a collection of color patches imaged by the output device, wherein metadata is embedded directly into the color patches of the color measurement target to uniquely identify the target through color measurement. The metadata-bearing patches in the target are used to communicate information through color measurement, and can contribute to the color characterization.
