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： The present invention provides a print apparatus and a printing method which enable high-grade images to be output at high speed without the need to drastically reduce the number of printing elements used to print leading and trailing end portions of a print medium. A first mask pattern used to print a middle portion of the print medium is different from a second mask pattern used to print the leading or trailing end portion of the print medium. The present invention thus eliminates the need to drastically reduce the number of printing elements used to print the leading or trailing end portion as with the prior art.

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.
