摘要： There is provided an ink jet printing apparatus capable of printing an image having few joining stripes. Dot count is performed regarding an image printed in the vicinity of the joining stripe, and print duty is judged. Next, a dot count value is determined from the print duty. Then, a print data correction rank is determined beforehand in accordance with properties of the printing apparatus, and image data to be printed in the vicinity of the joining stripe is added or thinned out. Thus, an image can be printed which has few black and white stripes.

摘要： In an ink jet printing apparatus in which satellites are produced, it is an object to minimize image impairments caused by the satellites in a variety of print modes. To this end, index patterns are prepared which have different sizes for different print modes. This enables satellites to land at print positions of main dots in other pixels in any of the print modes that have different distances between main dots and satellites. It is therefore possible to minimize image impairments caused by the satellites and to output a crisp image.

摘要： In a multipass printing system, a quality image is printed even when the number of passes is reduced to increase a printing speed. For this purpose, in a multipass printing system which repetitively alternates a printing scan, which causes the print head to eject ink from the nozzles as it moves in the main scan direction, and a feeding operation, which feeds a print medium in a sub scan direction, the feed distance of the print medium is set according to a density of an image being printed on the print medium.

摘要： A printing apparatus divides printing elements of a printhead into blocks, time-divisionally drives the printing elements, and prints a halftone image on a printing medium in accordance with a result obtained by performing digital-halftoning for input multi-valued image data in each matrix of a predetermined size. The apparatus includes a scanner for reciprocally scanning the printhead, a conveyor for conveying the printing medium in a direction different from a scanning direction of the printhead, and a controller for printing a halftone image in each matrix. An arrayed direction of the printing elements is the convey direction of the conveyor. The controller sets a size of the block to be equal to or an integral multiple of a size of the matrix in the convey direction. The digital-halftoning increases the number of dots from a center of the matrix as a density expressed by the multi-valued image data increases.

摘要： In an inkjet printing apparatus which generates satellites droplets, problems in an image attributable to the satellites are mitigated as far as possible. For this purpose, each parameter is adjusted to satisfy a relationship such that the distance between positions of placement of a main droplet and a satellite substantially agrees with an integral multiple of the width of an index pattern. As a result, a satellite is likely to be placed in a position overlapping a dot formed by a main droplet printed in the same area of a pixel located in the vicinity of the satellite, which prevents satellites from placement blank positions where no dot should be printed. Thus, the influence of satellites is mitigated, and problems in an image attributable to satellite are reduced.
