摘要： 17-valued data of a pixel in a multi-valued image is divided into two divisions for a two-pass printing, obtaining the division data. Next, by using an index pattern where arrangements of the numerals of 1 to 16 are dispersed, each dot data of C, M and Y in the division data is arranged. First, six dot data of C are assigned to the respective minor pixels of the numerals of 1 to 6 in accordance with a value of C1=6. Next, four dot data of M are assigned to the respective minor pixels of the numerals of 7 to 10 in accordance with a value of M1=4. Further, one dot data of Y is assigned to the minor pixel of the numerals of 11 in accordance with a value of Y1=1.

摘要： A data processing apparatus includes a mask processor for performing a mask process for binary data, which is obtained by a binarization process using a dot arrangement pattern, by using mask patterns having print permitting pixels to generate binary data used for each of a plurality of scans of a print head to a same area of a print medium. An arrangement pattern of pixels that correspond to both of first data representing the print permitting pixels in at least one of the mask patterns and second data representing pixels to which dots are printed in the dot arrangement pattern satisfies the characteristics of (a) power spectrums of a low frequency region are smaller than power spectrums of a high frequency region, and (b) a peak of the power spectrums does not exist in a region lower side of half of the low frequency region.

摘要： The present invention provides a mask for divided printing that completes an image by plural scans using inks of different plural inks, the mask being able to suppress possible grains during printing to reduce image degradation resulting from beading. If for example, among the print permitting pixels for which the total repulsive potential is to be calculated, a print permitting pixel Do has the highest total repulsive potential, changes in repulsive potential after movement of the pixels are determined and the print permitting pixel Do is moved to a pixel having the lowest total repulsive potential after the movement. This processing is repeated to enable a reduction in the total energy of the entire plane. Consequently, the print permitting pixels are appropriately dispersed in overlapping plane masks so as to have few low frequency components.

摘要： The interference between the dot arrangement pattern used for binarizing an image and the mask pattern for processing the dot arrangement pattern can be reduced and the well dispersed dot arrangement can realized by using the mask pattern. Specifically, in creating the mask, repulsive potential between the mask and the plane of dots arrangement pattern is calculated. That is, when the arrangement of print permitting pixels in the mask is determined, repulsive potential between print permitting pixels and dots on the plane of the dot arrangement pattern is calculated and print permitting pixels are arranged on the position where energy is the lowest and most dispersed. This enables print permitting pixels to be well dispersed in overlapping of the dot arrangement pattern and the mask. Consequently, as to dots formed by mask-processing and each scanning, their number is not unequally high in a specific scanning and dots are well dispersed.

摘要： In a binarization process employing dot arrangement patterns, the deviation of formed dots is prevented from occurring. Specifically, the arrangements of the dot arrangement patterns of each of four planes, which correspond to the groups of the four species of dot arrangement patterns of one certain level of five-valued data, are determined. In a process for determining the arrangements of the dot arrangement patterns of the four planes, the repulsive potential between the dot arrangement patterns in each plane and the repulsive potentials among the dot arrangement pattern in one plane and the dot arrangement patterns in the other planes are computed. Besides, the arrangements of the dot arrangement patterns of the planes are determined on the basis of the results of the repulsive potential computations.
