摘要： An inkjet printing apparatus and an inkjet printing method capable of suppressing generation of bronze phenomenon regardless of the color gamut are provided. For this purpose, in multipass printing, more pixels permitted to print by at least one type of achromatic color ink than pixels permitted to print by chromatic color ink in the last print scan to a unit region are set. Accordingly, it becomes possible to apply achromatic color ink having a high bronze phenomenon reduction effect on the topmost layer of the print medium, and thereby generation of bronze phenomenon can be suppressed without any hue shift.

摘要： Provided is an image processing apparatus and image processing method that are capable of outputting an image wherein seam lines caused by sudden conveyance error are difficult to notice even for a small number of multi passes printing. In order to achieve this, the number of dots that are printed in pixels is adjusted according to the density level so that the number of dots that are printed in pixels corresponding to boundary portions is larger than in pixels corresponding to areas that are not boundary portions, and so that the number of dots that are printed in pixels corresponding to boundary portions increases the higher the density level of the pixels is. As a result, it is possible to avoid the occurrence of white stripes in high-density areas without emphasizing black stripes in low-density areas.

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： When error diffusion processing is applied to thinned printing, the thinned printing can be performed without spoiling the dot printing pattern, and dot data is generated so that occurrence of grain may be suppressed by the dot arrangement distributed by the error diffusion processing. Specifically, the error diffusion of the binary data is performed in consideration of permitted positions shown by a division pattern of a nozzle array. That is, the binary data is permitted to be arranged only at a pixel position indicated by black in the division pattern of the nozzle array. Next, the result of having subtracted binary data from multi-valued data is applied as correction data of a multiple value, and this correction data is added to cyan multi-valued data of the nozzle array of first pass related to second plane generation.

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.

摘要： There is provided a dither pattern capable of reducing deterioration in image quality caused due to beading by suppressing the occurrence of grains in printing images using a plurality of color inks. If among threshold dots, for which repulsive force potentials are totalized, a threshold dot Do has the largest total, a change in repulsive force potential is obtained between before and after the movement of dot Do. The threshold dot Do is moved to a dot with the smallest total of repulsive force potentials between before and after its movement. By repeating this process, the total energy of all the three planes can be reduced, achieving a dot distribution, in which the number of low frequency components is reduced and the dots are appropriately dispersed, for superposed dither patterns.
