Abstract
A method of representing a half-tone level with dot sets each comprised of contiguous dots including the steps of providing a dot-set center at an offset point that is neither a center of a dot nor a midpoint between centers of dots, selecting dots that are included inside a symmetric-shape area having a center thereof at the dot-set center, an area size of the symmetric-shape area being commensurate with an input image level, and representing a half-tone level corresponding to the input image level by forming a dot set comprised of the selected dots.
