    摘要: An ink-jet printing method, an ink-jet printing apparatus and an ink-jet printing system, which are free from the deterioration of color development effect even if a plurality of color inks are used, caused by the overlap of different color inks on a printing medium, are proposed. For this purpose, when density data quantized to several ranks are converted finally to binary data by using predetermined dot arrangement patterns, a dot arrangement pattern different from those for other color inks is prepared for a particular color ink. Accordingly, it is possible to reduce as much as possible the probability that the particular color ink is overlapped with the other inks on the printing medium, whereby the color development of the particular color ink is effectively facilitated.

    摘要: A recording apparatus is configured to record an image on a recording medium by repeating a recording operation and a conveying operation. The recording operation is operative to apply a recording agent to the recording medium using a recording head while moving the recording head for scanning in a direction different from a predetermined direction. The recording head includes a plurality of recording elements arranged in the predetermined direction and adapted to apply the recording agent. The conveying operation is operative to convey the recording medium in a direction transverse to the scanning direction. The recording apparatus includes a recording control unit configured to perform the recording operation such that a number of the recording elements which are used to record an image on at least one of a front end portion and a rear end portion of the recording medium is reduced at a rate as compared to that of the recording elements which are used to record an image on a central portion of the recording medium, and a recording mode selecting unit configured to select a recording mode from a plurality of recording modes differing from one another in at least one of recording quality and recording time. The recording control unit changes the rate of reduction according to the recording mode selected by the recording mode selecting unit.

    摘要: A plurality of ejection portions are divided into groups, each containing at least one ejection portion, so that the suction-based recovery operation can be performed for each group independently. Since the number of ejection portions contained in each group differs, if an ink flow resistance varies among the different groups, simultaneous suction-based recovery operations can be done by using a common suction pump, without having to sequentially perform the suction-based recovery operations under an optimum pump driving condition. For this purpose, inner diameters of a plurality of ink discharge tubes running from a plurality of cap units, which cap a plurality of print head units having different numbers of ejection portions, to the common pump are differentiated. This allows different flows to be produced in different ink discharge systems, thus generating desirable ink flows for individual ink supply systems.

    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: 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.
