The 30-year history of the development of digital halftone technology within one company (Xerox) is followed from the viewpoint of the author’s involvement and participation. The history has an emphasis on the evolution in complexity from very simple threshold arrays through multi-center dots, high-addressability writing, non-orthogonal screens and other methods for avoidance of color moire. The paper is not meant to address all forms of digital halftoning, but concentrates on the requirements of laser-scanned xerography and clustered dots. Graphic examples of various halftone dot-growth sequences are provided. Key advances and lessons in the development of halftoning are summarized.
