GRIDLESS HALF-TONING - A REINCARNATION OF THE OLD METHOD

Despite continuing research and steady progress in the field of digita l halftones, there is a feeling that a wide gap in quality still remai ns between the best available and the best achievable results. A glanc e at man-made halftones readily confirms this feeling. To bridge this gap, we propose the use of computer-generated, yet gridless halftones. This involves solving the halftoning problem on the continuous 2D pla ne rather than on the usual discrete grid of pixels. In this article w e outline this new approach, describe its expected advantages over exi sting techniques and demonstrate some of them via a prototype system, DigiDurer, developed for this purpose.
