Abstract: A plurality of recording heads for ejecting inks of different colors are reciprocally moved relative to a recording medium, and printing operations are performed by executing main scans in forward and backward scans of the recording heads. In this case, an area printable in a single main scan is recorded by performing a plurality of main scans using a plurality of thinning patterns in which an m.times.n pixel group is defined as a unit pixel group, and the pixel groups are arranged at non-neighboring positions, and which have a complementary arrangement relationship therebetween. A high-quality color image free from time difference nonuniformity, and density nonuniformity caused by, e.g., variations of recording elements is obtained at high speed.

Abstract: A plurality of recording heads for ejecting inks in different colors are aligned, and are reciprocally moved in the alignment direction, and an image is recorded by performing main scans in both the forward and backward paths of the reciprocal movement, and performing a sub-scan after each main scan. An area recordable in a single main scan is thinned out according to thinning arrangements having a complementary relationship therebetween, and thinned-out images are recorded in a plurality of main scans. During this interval, the sub-scan is performed in a direction opposite to the normal sub-scan direction at a predetermined period.

Abstract: A process for recording information on a recording substrate, in which a print head with number (a) of printing elements moves back and forth over print positions, one print line at a time. Partial numbers of printing elements form subgroups in accordance with predetermined formations specific to the print lines. These subgroups are allocated to the print positions of a print line and are formed by at least partly differing printing elements. The individual printing elements of the respective subgroup are selectively controlled at the print positions in accordance with print data to produce a print pattern line. On completion of a subsequent print pattern line, the predetermined formation for a subsequent print line conforms, at least on the continuation side, to the predetermined formation of the preceding print line. Stripes caused by line continuation errors or ink ribbon structure errors are distributed throughout the printed image so as to be vertically offset. In contrast to uniform structures, structures which are distributed in this way can barely be discerned by the human eye.

Abstract: In order to print a unit area of a print medium by a first printing scan and a second printing scan, dither patterns are formed which can control the arrangement of dots on the print medium without adverse effects of density unevenness and graininess, that are caused by printing position displacement. Regarding first and second dither patterns, information indicating whether or not a threshold is already set to a reference pixel and one or more pixels around the reference pixel in the first dither pattern is obtained for cases where each pixel in the first dither pattern is the reference pixel. A pixel in the second dither pattern to which a predetermined pixel is to be set is determined based on the obtained information. The first and second dither patterns formed in the above manner are associated with the first printing scan and the second printing scan, respectively.

Abstract: A control device includes an execution unit, a determining unit, and a setting unit. The execution unit controls a printing unit to execute a multi-pass printing for a predetermined partial area of printing medium by executing sub scans and a prescribed number of times of main scans. In the main scan, a print head of the printing unit forms dots on the recording medium while being conveyed in a main scanning direction. In the sub-scan, the printing medium is conveyed in a sub-scanning direction. The determining unit determines an acceptable range based on an actual conveyance error in the sub-scanning direction. The setting unit sets the prescribed number to N when a representative value of predetermined partial area falls in the acceptable range, and sets the prescribed number to M being an integer greater than N when the representative value does not fall in the acceptable range.

Abstract: An inkjet printing device uses a print head including a first nozzle array for ink ejection and a second nozzle array for ejection of an image quality improvement liquid (CL), and the device prints an image on a print medium by repeating a print scan. The inkjet printing device includes a first controller for, during a first print scan, allowing nozzles on an upstream side of the first nozzle array in the conveying direction to eject the ink, and a second controller for, during the first print scan, allowing nozzles on an upstream side of the second nozzle array in the conveying direction to eject the liquid (CL) into an ink ejection area. In aaddition, a third controller, during a second print scan after the first print scan, allows nozzles on a downstream side of the second nozzle array in the conveying direction to eject the liquid (CL) into the ink ejection area.

Abstract: A control device includes an execution unit, a determining unit, and a setting unit. The execution unit controls a printing unit to execute a multi-pass printing for a predetermined partial area of printing medium by executing sub scans and a prescribed number of times of main scans. In the main scan, a print head of the printing unit forms dots on the recording medium while being conveyed in a main scanning direction. In the sub-scan, the printing medium is conveyed in a sub-scanning direction. The determining unit determines an acceptable range based on an actual conveyance error in the sub-scanning direction. The setting unit sets the prescribed number to N when a representative value of predetermined partial area falls in the acceptable range, and sets the prescribed number to M being an integer greater than N when the representative value does not fall in the acceptable range.

Abstract: P (fifteen) recording heads are arranged in two columns in a zigzag pattern in a recording unit. The P recording heads are divided into N (two) groups in the sub-scanning direction (up-down direction in the figure). The N (two) controllers respectively control the recording heads pertaining to corresponding groups. Therefore, the number of the boundary (M/S boundary line) of the recording regions (master recording region and slave recording region) of the recording heads controlled by the different controllers becomes at least N−1 (one).

Abstract: An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.
