Abstract
The present disclosure relates generally to signal encoding. Digital files representing artwork for printed objects, e.g., product packaging, labels and hangtags, can be encoded to carry information. One implementation obtains a color image representing CMY color channels, and alters the color image to include an encoded signal by altering values representing CIELAB a* and b*, all the while keeping L* on or within a predetermined tolerance of a contour representing a constant value. Other implementations are provided.
