摘要：
The invention provides a printing system by which a greater number of pixels are used to form a basic pattern and moirés and artifacts can be reduced. A binarization dither matrix pattern is configured by arranging a plurality of pixels to be successively turned on in a matrix and has a plurality of specific points P1 and P2 provided at substantially point symmetric positions with respect to the position C of the center of figure thereof. Those of the pixels which are adjacent to be turned on pixels are preferentially turned on in order beginning with those of the pixels which are positioned near to the specific points P1 and P2 to individually form successive halftone dots. When a number of pixels substantially equal to one half the number of pixels which form the binarization dither matrix pattern are turned on in order, the turned on pixels and unturned on pixels form a checkered pattern in the binarization dither matrix pattern.
