Theoretical and experimental research is being conducted on topics related to monochrome and multicolor halftone printing systems. Our goal is to make contributions to improve the understanding of printing for higher image quality, better gray-scale and color reproduction, and faster printing speed. Major aspects of our proposed research include the following three topics. First, we have devised a new sampling method, i.e., a new centering concept, for computing the overlapping correction in digital halftoning. This novel concept will greatly reduce the complexity in making the measurement-based overlapping correction. We propose to investigate corresponding halftoning algorithms and built-in-printer hardware for real-time monitoring and calibration in order to maintain the optimum performance of hard-copy devices. Secondly, we plan to extend the new centering concept to multicolor halftoning studies. For the third topic, we propose to conduct system research for multiplexed output devices. The research will be focused on architectures which provide support for a multi-output system. This program of research is heavily leveraged by participation from the ARO-URI in Optoelectronic Systems, the new Center for Electronic Imaging Systems, and industrial sponsors including several U.S. Corporations who are leaders in imaging.
