Paper Abstract

Moire patterns can be formed when the spatial frequencies in a half-tone screened picture beat against the frequencies in a scanning raster. Very small periodic defects in the scanning raster can produce regular irregular bands and patterns which can spoil the quality of the printed result. Consideration of the factors which cause the patterns, and the sensitivity of the visual response, allow engineering tolerances to be placed on the raster scanning mechanism.
