Abstract: When executing the gradation lowering processing to a data area in the lower side in multi-valued print data 403, an error generated by executing the gradation lowering processing to the data area in the lower side is stored in an information storage area 901B. On the other hand, the error thus distributed and stored is used for executing the gradation lowering processing to the data area “J” (Jth line) in multi-valued print data 404 relating to the next scan. In this way the error generated when executing the gradation lowering processing to the multi-valued print data is stored, which is used at the time of executing the gradation lowering processing to the multi-valued print data relating to the next scan. Therefore, the density is stored by receiving and delivering the error between the multi-valued print data in a scan unit.

Abstract: Multi-valued image data stored in an input image buffer are read out for each time of scans, and the color space conversion and image distribution are performed to read multi-valued image data. The binarized result is sent to the print buffer and at the same time, is accumulated as the print information to execute processing of reflecting it to the image distribution processing of the next pass. It is possible to appropriately restrict the density fluctuation due to the print position shift between planes without providing pixels where dots are overlapped and printed more than necessary. With this, by accumulating the multi-valued image data at the stage of RGB in the input image buffer to read out data stored in input image buffer for executing processing, a capacity required for input image buffer does not change even if the number of the ink colors provided on the printing apparatus increases.

Abstract: A channel selection section selects whether the subsequent processing to the image data is executed by image distribution precedence processing or by gradation lowering precedence processing in accordance with channel information of the image data. That is, in regard to the channels of C, M and K with relatively high density among inks, the image distribution precedence processing excellent in robustness is selected. On the other hand, in the ink of the color with high brightness or low density, even if the print position of the dot is shifted, the density change due to this shift is not so much large. It is possible to restrict an increase in the processing load due to executing the gradation lowering processing after the distribution processing to each of the plural divided images by thus not selecting the image distribution precedence processing in consideration of the robustness.

Abstract: 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.

The resulting signal is provided to the modulator as a feedback signal. The modulator executes the pulse modulation on a difference value between the drive waveform signal and the feedback signal.
