摘要 |
<p>The quantity processing is executed to data distributed for each color. Binary data obtained by this quantization processing are selected only in regard to a color generating print quantity information. Filtering processing is executed to the binary data of the selected color to generate the print quantity information. In the quantization processing for a second plane, data found by converting the print quantity information generated in the first plane processing into a minus value are added to the multi-valued data. In the quantization processing in the second plane added, the value of the multi-valued data is made small and in the quantity, probability that the multi-valued data become binary data printing the dots is made small. That is, a ratio where dots in the first plane and dots in the second plane overlap and are formed can be made small.
