摘要： For a horizontally arranged print head, in which nozzle rows are arranged parallel with a scanning direction of the print head, two of a plurality of ink colors used, which have the greatest hue difference, are selected. Between the nozzle rows for these two colors, at least two nozzle rows for other colors are arranged so that the nozzle rows for the two colors have a large inter-nozzle-row distance. The resulting print head is used for printing. If cyan, light cyan, magenta, light magenta, yellow, and black are used as ink colors, the light cyan, black, yellow, and light magenta inks are arranged between the cyan and magenta inks, having a great hue difference.

摘要： While a conveying error of a roller depends on the eccentricity of the roller, the amount and the state of the eccentricity sometimes makes the roller have different conveying errors from one point in the longitudinal direction of the roller to another. There is provided a construction for obtaining a correction value that is suitable for the correction of the conveying error even in such a case as described above. To this end, plural test patterns are formed in the longitudinal direction of the roller. Then, a suitable correction value for correcting the conveying error that depends on the eccentricity of the roller is obtained on the basis of these test patterns.

摘要： By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained. An accumulated amount of conveyance errors is reduced by narrowing a nozzle-use range and by reducing a conveyance amount over an entire printing region according to the number of colors to be used and desired printing quality in printing an image. Moreover, the nozzles used when the nozzle-use range is narrowed are not fixed, and are switched to be used as appropriate. This prevents only certain nozzles from being used concentratedly, and allows all of the nozzles to maintain substantially the same ejection performance.

摘要翻译： 通过抑制由于输送辊的偏心导致的打印介质的输送不足导致的点形位置的偏差，获得了不可见度较小的打印图像。 根据要使用的颜色数量和打印图像期望的打印质量，通过缩小喷嘴使用范围并减少整个打印区域的输送量来减少传送误差的累积量。 此外，当喷嘴使用范围变窄时使用的喷嘴不固定，并且适当地切换使用。 这防止了仅某些喷嘴被集中使用，并且允许所有喷嘴保持基本相同的喷射性能。

摘要： An ink jet printing method is provided which, although it uses an ink jet print head with a fixed small ink ejection volume, can form an image with a desired density by performing data processing and printing at a lower pixel density. The dot arrangement pattern that determines the presence or absence of a printed dot in each of a plurality of element areas making up each pixel is allocated to the individual pixels according to their grayscale level. Then the printing dots are divided into a plurality of scans of the print head. At this time, for those pixels having a predetermined grayscale level, a plurality of dots are printed overlappingly in each of predetermined element areas of these pixels. This arrangement allows a greater number of dots than is determined by the allocated dot arrangement pattern to be printed in these pixels according to the grayscale level.

摘要： In a printing apparatus which prints an image on a printing medium by alternately performing printing of an image on the printing medium by using a printing unit and conveyance of the printing medium relative to the printing unit, the conveyance amount in conveyance is corrected by using the first and second parameters for correcting the conveyance amount in accordance with different factors. This makes it possible to correct the conveyance amount in accordance with the deviation of the printing position due to the different factors.

摘要： A mask pattern is employed for multi-pass printing. The mask pattern is the sum of a first mask pattern, relative to a first location that includes areas wherein dots are to be printed when a density value is smaller than a predetermined value, and a second mask pattern, relative to a second location that includes areas wherein dots are to be printed only when the density value is equal to or greater than the predetermined value. Using multiple scans, up to one dot is printed in the first region, while two dots or more are printed in the second region. With this arrangement, since the first mask pattern, which greatly affects a low-duty image, and the second mask pattern, which greatly affects a high-duty image, can be independently designed, problems that occur with images prepared at individual duties can be coped with by the separate mask patterns.

摘要： For a recording apparatus capable of supplying a plurality of different color inks to a plurality of recording element substrates, when a condition for performing maintenance on a first recording element substrate is met, it is determined whether or not to perform maintenance on a second recording element substrate according to how close the second recording element substrate is to meeting the condition. Since maintenance is performed on the first and second recording element substrates in such a manner, unnecessary maintenance operations will be prevented from being carried out multiple times within a short period of time. Accordingly, the total amount of time required for maintenance is reduced.

摘要： The ink jet printing apparatus forms an image on a print medium with the following two operations. The printing operation makes a print head perform scan motions in a predetermined direction on the print medium, the print head having an array of nozzle rows corresponding to the required number of ink colors, each scan motion involving the ink being ejected from nozzles onto the print medium. The print medium feeding operation moves the print medium and the print head relative to each other a predetermined amount in a direction different from a direction of the scan motion between the scan motions. In a print mode using a small number of ink colors employed for printing, unidirectional printing is performed such that the nozzle row of a black ink to be ejected reaches a print start position when amplitude of vibration of the print head is a predetermined amount or less.

摘要： An ink jet printing apparatus includes a print head that is an array of a plurality of nozzles arranged according to each color of ink in a predetermined direction. The apparatus is provided with a plurality of print modes, each using a different number of colors of ink for printing. In a print mode using a smaller number of colors of ink for printing (e.g., a monochrome print mode) out of the plurality of print modes, a print method is adopted, in which an image of a predetermined area is formed by a greater print pass count than the print pass count for the predetermined area in a print mode using a greater number of colors of ink for printing (e.g., a color print mode).
