Abstract:
Information is encoded in an image signal by exploiting spectral differences between colors that appear the same when rendered. These spectral differences are detected using image sensing that discerns the spectral differences. Spectral difference detection methods include using sensor-synchronized spectrally-structured-light imaging, 3D sensors, imaging spectrophotometers, and higher resolution Bayer pattern capture relative to resolution of patches used to convey a spectral difference signal.

Claim (Index 23):
A method of encoding a machine-readable data signal in a printed object, the method comprising, with a programmed processor:\n generating an information signal comprising message symbols; mapping message signals of the information signal to insertion locations within a host image signal; at the insertion locations, inserting the information signal by computing values for controlling application of a spot color ink and a combination of process color inks, the values for controlling application of process color inks forming a spectral difference signal between process color ink applied at a first pixel location and spot color ink applied at a second pixel location to encode a message signal in relative spectral difference between the process color ink at the first pixel location and spot color ink at the second pixel location, the computing encoding a relative spectral difference at the first and second pixel locations that conveys the message signal within the host image, the spectral difference signal representing a distinguishable spectra between a spot color and a combination of process colors that appear similar in the human visual system; wherein the relative spectral differences at the insertion locations comprise differences between spectral distributions of spot and process color inks at corresponding pairs or sets of locations.
