This paper proposes a lossless (reversible) data compression method for bi-level images, particularly printing images. In this method, called Dispersed Reference Compression (DRC), the coding scheme is changed according to the characteristics of the images to be compressed by Evolvable Hardware. Computational simulations demonstrate that DRC provides compression ratios that are up to 30% better than the current international standard for bi-level image compression. This paper also reports on the progress in discussions to incorporate a DRC-based compression method as an improvement to the international standard.
