    摘要: The present invention allows for creating high quality images by coping with a variety of kinds of print mediums without having to prepare large-sized, large-capacity power supply and ink supply source. For this purpose, this invention detects the number of printing elements to be driven in a predetermined check area set in one scan area of the print head. If the detected value is greater than a predetermined threshold, either the number of printing elements to be driven in one scan period of the print head or one scan period from when the print head starts the printing scan until the next printing scan is started is selected and changed according to the set printing condition and the printing operation is performed accordingly.

    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 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 object of this invention is to prevent prolongation of the time taken for a suction recovery operation while suppressing wasteful consumption of ink in the suction recovery operation. An ink-jet printing apparatus includes a plurality of caps which, when a plurality of nozzles of an ink-jet head are divided into a plurality of nozzle groups, are arranged one by one for the respective nozzle groups, and cap the respective nozzle groups, a suction pump which generates a negative pressure in the plurality of caps to suck ink from the plurality of nozzles, and is arranged commonly for the plurality of caps, and a control unit which controls the suction pump so as to make the negative pressure by the suction pump act on all the caps when a common negative pressure is generated in the plurality of caps, and make different negative pressures by the suction pump act sequentially on the plurality of caps when different negative pressures are generated in the respective caps.

    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.
