Abstract: Embodiments are disclosed for generating an infrared mark indicator comprised of security information in a printed image. Image data is rendered to a CMYK image. A black plane of the CMYK image is separated and transformed to a frequency domain wherein the frequency components are alternated to encode the watermarking message.
