ABSTRACT:
For reproducing a picture with a density gradient through printing, an overlapped region is provided in a high density dot reproduction range and a low density dot reproduction range. The switch-over between the high density dot at the overlapped region is conducted where the picture density sharply changes. This reduces the unfavorable perception of quality differences in a printed picture resulting from the switch-over between the high and low density dots.
