This article may be accessed on the publisher's website (additional fees may apply) at: http://www.imaging.org/store/epub.cfm?abstrid=2450 We present a novel class of dispersed-dot masks for digital halftoning. These masks are based on simple algebraic rules using a Fibonacci-like number sequence (also known as linear pixel shuffling (Anderson, 1993)), which permits masks of an unlimited variety of sizes and number of discrete gray levels to be easily constructed. The masks tile the plane, but not necessarily ina rectangular manner. They produce seamless halftoned images.
