Abstract:
1. A printing control apparatus for controlling a printing apparatus which can print the same pixel by using a plurality of print elements arrayed in a predetermined direction on a print head, the plurality of print elements being arranged in different print element arrays extending in a direction crossing the predetermined direction, relative movement between the print head and a print medium being effected along the predetermined direction, a unit area on the print medium being printed by one relative movement between the print head and printing medium, the printing control apparatus comprising: a quantizing unit configured to quantize input image data by dithering; a distributing unit configured to create image data to be distributed to each of the plurality of print elements from the quantized image data by using a plurality of distribution patterns which have a complementary relation to each other, the plurality of distribution patterns corresponding to the plurality of print elements and determining a portion to be printed by each of the plurality of print elements, the distributing unit being able to switch, in a moving period corresponding to the one relative movement, a correspondence relation between the plurality of print elements and the plurality of distribution patterns, the number of which is the same as that of the plurality of print elements, while keeping the complementary relation between the plurality of distribution patterns; and a control unit configured to control the print elements based on the image data to be distributed to the print elements.
