摘要： In order to vary a threshold value for performing an error diffusion process depending on a pixel position, a threshold value matrix configured to have pluralities of rows and columns is prepared. In this case, pieces of data in the threshold value matrix are arrayed such that average values in the respective rows and average values in the respective columns are almost the same value. If such a threshold value matrix is used to perform the error diffusion process, the dot sparseness and denseness do not occur with a period of the matrix, and therefore the pattern or sweeping phenomenon specific to the error diffusion can be suppressed.

摘要： An ink jet printing apparatus, for each level, employs a plurality of density patterns to prevent cancellation of a granularity reduction effect that has been provided by an increase in resolution. Specifically, when determining an arrangement of dot-on areas in the density pattern, the dot-on areas is not located in the areas of a first row of the each of the plurality of density patterns. Thereby, whitish areas appear with the same cycle as a use cycle of the density patterns in a longitudinal direction and thus the whitish areas is not unevenly located. As a result, granularity is prevented from increasing.

摘要： A dither pattern is formed in such a manner that threshold values 1 to 16 are dispersed in regard to the order of magnitudes of the threshold values. First, there is made a calculation of multiplying each value of the image data by a ratio of 1/2. Thereby, there is produced the divided 17-valued data where every value of all pixels is “2”. Next, binarization is carried out for the divided data by using the dither pattern. As a result, binary data at the first pass is obtained. Next, there is obtained the data by a product of a ratio (1/2+1/2) obtained by adding 1/2 to the above ratio and each value of the image data. Binarization is carried out for the image data by using the dither pattern. This produces binary data. Finally, dot data for the second pass is obtained by subtracting data from the binary data.

摘要： The printing elements of each printing element array are divided into blocks. A block to be driven and a block not to be driven are determined for each scanning of a printhead. The printhead is driven to print by complementing blocks to be driven by each scanning in a plurality of scanning operations. In each scanning, the printhead prints while making a printing area corresponding to at least one ink different from a printing area corresponding to another ink.
