Abstract

We propose a modification to the process of error-diffused quantization often used for printing computer-generated holograms on bitonal devices. The output of many devices (e.g. laser printers) consists of `dots' printed at locations on a fixed grid. The printed patterns often are modeled as ideal square pixels. However, real dots typically are more round than square, and often overlap adjacent pixels. These variations can affect the quality of the reconstructed hologram significantly.
