Abstract

In this paper, we compare electrophotographic printing and ink jet printing, observing the shape of printed dots or clusters of dots, and consider the factors which affect the uniformity of dot size. It is important to discuss the shape of printed dots because in the halftoning process, dispersed dots and clustered dots produce the mid-tone images. As the results of our experiment, it is clear that in the case of dots printed by electrophotographic method, the uniformity of the shape increases in proportion to the cluster size. On the other hand, in the ink jet printing method, the increase of uniformity is comparatively less obvious.
