摘要： The present invention aims to obtain preferable correction values to correct the conveying error of a conveying roller in accordance with the size of a printing medium, even when the conveying error caused by the eccentricity of the roller varies from a point to another in the longitudinal direction of a roller, depending on the amount and the state of eccentricity of the roller. To achieve this object, correction values are acquired using the whole part of or only a part of plural test patterns formed in the longitudinal direction of the roller. The correction values thus acquired correspond to the respective zones where the test patterns are formed.

摘要： Mask patterns to be used for multi-pass printing make it possible to make a print with a higher quality at a higher speed. Specifically, by performing a swapping process with adjacency forbiddance, two points in the horizontal direction, or the scanning direction of a printing head, are selected in a buffer in which codes for each scan pass are set depending on printing ratios of a gradation mask. Subsequently, codes are swapped between the two points. By this swap, adjacencies between print permitting areas are eliminated in the mask pattern. As a result, when driving frequencies set for the printing head is kept constant, the scanning speed can be doubled at minimum.

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： In an ink-jet printing apparatus which includes a plurality of printing heads, each having an array of ink discharging elements, preliminary discharge of driving the elements of at least one printing head is performed a predetermined number of times. The printing head for which the preliminary discharge is to be performed is switched in a predetermined cycle. In performing the preliminary discharge, switching of the printing head is so controlled as to perform preliminary discharge a desired number of times for all the elements of the printing heads by repeating the cycle.

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.
