Claim One:
1. A system that creates a data-bearing image ( 391 ), comprising: a halftone image generator ( 374 ) that receives a carrier image ( 371 ), the halftone image generator ( 374 ) including: an image scaler ( 379 ) that scales the carrier image ( 371 ) to produce a scaled image, and a halftoner ( 380 ) that applies a clustered-dot halftone screen to the scaled image to produce a halftone image so that a resulting number of cells in the halftone image conform to a cell count ( 372 ) that includes a horizontal cell value and a vertical cell value; an encoder ( 375 ) that produces a data-bearing halftone image by encoding payload data into the halftone image, including shifting pixel clusters within cells of the halftone image that include pixel clusters; and, an output device ( 376 ) configured to output the data-bearing halftone image.
