ABSTRACT:
Improved methods for reproducing an image are disclosed. Images are created using dots or patterns which are substantially quasiperiodic and thereby eliminate Moire interference patterns. In multi-color applications, the disclosed methods simplify the color overlay process. Also disclosed are patterns for creating half-tone images which do not exhibit Moire interference patterns when overlaid. Electronic display apparatus using these patterns are also disclosed.
