    摘要： Disclosed is an inkjet printing apparatus for forming an image by repeatedly causing the scanning of a printhead that prints an image in a scan area using inks of a plurality of types. Residual duty, which is obtained by quantifying the mixed state of the inks used in printing the image in the scan area, is defined. The residual duty with regard to the next scan area is found from image data, the scanning direction for printing in the next scan area is decided based upon the residual duty, and the area is printed in the scanning direction that has been decided. Thus, back-and-forth scanning and unidirectional scanning are used jointly in appropriate fashion in accordance with the printed image. As a result, high-quality printing of an image becomes possible and a higher printing speed is achieved.

    摘要： A method and an apparatus for ink jet printing use a print head including a first nozzle group for discharging a first ink, a second nozzle group for discharging a second ink and a third nozzle group for discharging a printability improving solution. The third nozzle group is displaced between the first nozzle group and the second nozzle group. The first nozzle group discharges the first ink on the printing medium based on image data to form an image, the third nozzle group discharges the printability improving solution on the image formed on the printing medium by means of another step, and the second nozzle group discharges the second ink on the image formed on the printing medium. The printability improving solution has higher penetrability into the printing medium compared to the ink.The method and apparatus can attain a clear colored, high density image without color mixing, which has high water resistance on plain paper, with a low running cost.

    摘要： An ink jet recording apparatus which carries out, in a decimated multipass print mode, paper transfer by an extra amount (2.5 .mu.m) beyond a standard paper transfer amount corresponding to a quarter of the total number of nozzles in the nozzle arrangement of a recording head. This can displace dots formed in subsequent scannings from dots formed in previous scannings by amounts of 2.5 .mu.m, 5 .mu.m, 7.5 .mu.m and 10 .mu.m, and reduce the overlap of the dots at boundary regions in the decimated multipass print mode. In a one pass print mode, the paper transfer amount per scanning is set less than the sum total of the four paper transfer amounts of the decimated multipass print mode so that dot overlaps take place as countermeasures against paper transfer errors. This makes it possible to achieve high quality image recording by preventing both the white bandings at the boundary regions in the one pass print mode that prints one unit area by one scanning, and black bandings at boundary regions in the decimated multipass print mode that prints the one unit area by a plurality of scannings, thereby achieving high quality recording.

    摘要翻译： 一种喷墨记录设备，其以抽取的多页打印模式执行超过相对于记录的喷嘴布置中的喷嘴总数的四分之一的标准纸张传送量的额外量（2.5μm）的纸张传送 头。 这可以将在先前扫描中形成的点的后续扫描中形成的点移位为2.5μm，5μm，7.5μm和10μm的量，并且在抽取的多次打印模式中减少边界区域处的点的重叠。 在一次通过打印模式中，每次扫描的纸张传送量被设置为小于抽取的多次打印模式的四个纸张传送量的总和，从而发生点重叠作为对纸张传送错误的对策。 这使得可以通过防止在一次打印模式中的边界区域上的白色条纹同时进行一次扫描来打印一个单位区域，并且在抽取的多次打印模式中的边界区域处的黑色条带 一个单位面积通过多次扫描，从而实现高质量的记录。
