A New Digital Screening Algorithm Based on Delaunay Triangulation

This paper proposes an algorithm for digital screening based on Delaunay triangulation. The technique has solved moire patterns phenomenon when printing in traditional pattern for the random of dot. The algorithm can give a real-time result for its high efficiency. Output image is accurate and soft since gray value distributes uniformly. It has a low request for equipment and subsequent handling, and entirely meet the needs of traditional printing technology.
