Technical Report CIS9323

Despite continuing research and steady progress in the field of digital halftones, there is a feeling that a wide gap in quality still remains between the best available and the best achievable results. A glance 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 plane rather than on the usual discrete grid of pixels. In this article we outline this new approach, describe its expected advantages over existing techniques and demonstrate some of them via a prototype system, Dig^{\mbox{\boldmathi}}_D\"{urer}, developed for this purpose.
