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.
摘要翻译： 当通过奇数或偶数次的双向打印扫描在预定区域中完成图像时，本发明使得可以抑制图像缺陷和浓度变化的线，从而高速打印高质量图像。 在通过奇数的双向打印扫描完成图像时，使用第一和第二稀疏图案来减小用于小墨滴和大墨滴的打印数据。 第一和第二稀疏图案使小墨滴和大墨滴的打印数据变薄，使得奇数扫描的所有正向打印扫描的总打印比与所有向后打印扫描的总打印比之差 使用第一稀疏图案时的奇数次扫描与使用第二细化图案时的扫描次数不同。

摘要： When paper dirt that could not be removed completely by the wiping gets trapped in the recessed portions formed in the ejection port face, the paper dirt may interfere with ejection ports, giving rise to a possibility of image impairments. To deal with this problem, the ejection ports and the recessed portions in the print head are shifted from each other so that their positions are not aligned in the wiping direction.

摘要： An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.

摘要： A recording device drives a recording head mounted on a carriage while main-scanning by moving the carriage in a direction generally orthogonal to the sheet-feeding direction of a sheet. The recording device drives a first nozzle of the recording head at an upstream side in the sheet-feeding direction of the sheet to form a first dot pattern while scanning the carriage and drives a second nozzle at a downstream side in the sheet-feeding direction of the sheet to form a second dot pattern. The recording device feeds a region where the first dot pattern is recorded to a position facing the second nozzle. The second dot pattern is recorded in a region where the first dot pattern is not recorded.

摘要： The present invention provides an ink jet printing apparatus and a method for controlling temperature for the ink jet printing apparatus wherein the temperature of a print head, which may lower during printing, is controlled before printing without using any sub-heater to allow a favorable ejection condition to be established without reducing the head temperature below a predetermined value. Thus, scan width information and dot count information are acquired before a carriage starts scanning to determine the heating temperature of the print head on the basis of the information.
