    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 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.

    摘要： An ink-jet printing method, an ink-jet printing apparatus and an ink-jet printing system are proposed, 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. 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 in 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.
