Paper Abstract

Moire formation is often a major problem in the printing applications. These artifacts introduce new low frequency components which are very disturbing. Some printing techniques, e.g. gravure printing, are very sensitive to moire. The halftoning scheme used for gravure printing can basically be seen as a 2D non-isotropic subsampling process. The more problem is much more important in gravure printing than in conventional digital halftoning since the degree of freedom in constructing halftone dots is much more limited due to the physical constraints of the engraving mechanism.
