A system generates a secure barcode and prints the secure barcode on a substrate. The barcode includes a first set of cells of a first color and a second set of cells of the second color. A first vector pattern is encoded onto pixels for first set of cells of the barcode, and a second vector pattern is encoded onto pixels that correspond to the set group of cells of the barcode. The vectors in each pattern will have substantially the same colors, thicknesses and frequencies, but will be out of phase with respect to each other. The system will generate a secure barcode that vectors of each pattern.
