摘要： When completing an image in a predetermined area by an odd or even number of bidirectional printing scans, this invention makes it possible to suppress lines of image defects and density variations and thereby print a high-quality image at high speed. In completing an image by an odd number of bidirectional printing scans, the print data for small ink droplets and large ink droplets are thinned using the first and second thinning pattern. The first and second thinning pattern thin the print data for small ink droplets and large ink droplets so that a difference between the total print ratio of all forward printing scans of the odd number of scans and the total print ratio of all backward printing scans of the odd number of scans when the first thinning pattern is used differs from that when the second thinning pattern is used.

摘要： Quality degradation of a print image due to a deviation amount in a landing position of ink is prevented while suppressing degradation of through-put. In a method of completing a print to a unit region by at least one reciprocal scan to the unit region of a print medium by a printing head in which plural ink ejection ports are arrayed for ejecting ink, a printing rate in a scan direction where a deviation amount in a landing position of ink in an array direction of the ink ejection ports is relatively large is set relatively low and the printing rate in the scan direction where the deviation amount in the landing position of ink in the array direction of the ink ejection ports is relatively small is set relatively high.

摘要： The present invention provides a liquid ejection head which includes a plurality of ejection ports 302 arranged so as to form an ejection port row and which, after a recovery process of expanding and transferring a bubble toward an ink supply port, allows the bubble to be smoothly removed from a nozzle 310. electrothermal transducing element A plurality of nozzle filters 306 are arranged between an ink supply port and the ink channel 304 so that ink supplied to the bubbling chamber 303 through the ink supply port is passed between the nozzle filters 306 to separate impurities contained in the ink, from the ink. When a distance between an ink channel inlet 311 and the nozzle filter 306 is defined as L1 and a distance between the adjacent nozzle filters 306 is defined as L2, a relationship between L1 and L2 satisfies L1≦L2.

摘要： There are provided an inkjet printing apparatus and an inkjet printing method, whereby, the temperature of a print head is controlled and the ejection volume of ink to be ejected is stabilized to print a high-quality image, even at a high printing duty. Based on print data, an ejection number of ink to be ejected into a unit printing area is counted. The print head is heated to a target temperature that is raised in consonance with an increase in the count value.

摘要： An ink jet printing apparatus and printing method are provided that can, without the addition of a special structure, suppress density imbalance between the print images formed by ink ejected from each of the ejection ports formed on a print head. As for the plurality of ejection ports, one portion of them are established as multiple impact ejection ports that form multiply impacted pixels at which the number of times ink is impacted at the same area is greater than at other pixels of the print area. And, print control is carried out such that more multiply impacted pixels are printed at print areas printed using ejection ports at the ends of the print head than at print areas printed without using ejection ports at the ends of the print head.
