Reversible Data Hiding Associated with Digital Halftoning That Allows Printing with Special Color Ink by Using Single Color Layer
This addresses a domain-specific issue in digital printing and data hiding, offering an incremental improvement for compatibility in printing applications.
The paper tackles the problem of enabling both normal printing and printing with special color ink from a single image by proposing a reversible data hiding framework that embeds compressed special color layer information into the general color layer, achieving high marked image quality in experiments.
We propose an efficient framework of reversible data hiding to preserve compatibility between normal printing and printing with a special color ink by using a single common image. The special color layer is converted to a binary image by digital halftoning and losslessly compressed using JBIG2. Then, the compressed information of the binarized special color layer is reversibly embedded into the general color layer without significant distortion. Our experimental results show the availability of the proposed method in terms of the marked image quality.
