    • One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio.
    • 根据特定墨水和非特定墨水的重叠条件,用于施加特定墨水的一次或多次扫描被改变,并且抑制了特定墨水喷嘴使用频率中的偏压和通过之间的打印比率的偏差。 为此,基于特定油墨和非特定油墨的施加量信息来确定用于施加特定油墨的一次或多次扫描。 例如,用于施加特定墨水的一次或多次扫描被确定为使得对于非特定墨水与特定墨水的应用比例更大的单位像素,多次扫描的后半部分所施加的特定墨水的比率更大 比预定比例,其比非特定墨水与特定墨水的应用比例小于预定比率的单位像素。

    • The present invention provides a printing method comprising a selecting method of selecting defective print elements to be corrected on the basis of, for example, the positional relationship among the defective print elements in a print head so that if there are a plurality of defective print elements such as non-ejection nozzles, not all pixels otherwise printed by the defective print elements are to be corrected but efficient corrections can be achieved on the basis of correlations with the lifetimes of other normal print elements, as well as a correcting method of making up for print data corresponding to the defective print elements selected, and a printing apparatus using the printing method.
    • 本发明提供了一种打印方法,其包括:基于例如打印头中的缺陷打印元件之间的位置关系来选择要校正的有缺陷的打印元件的选择方法,使得如果存在多个有缺陷的打印元件 例如不喷射喷嘴,不是由缺陷打印元件打印的所有像素都将被校正,而是可以基于与其它普通打印元件的寿命的相关性以及补偿的校正方法来实现有效的校正 对应于所选择的有缺陷的打印元素的打印数据,以及使用打印方法的打印设备。

    • Provided are an inkjet printing apparatus and an inkjet printing method in which a high-quality image free of peeling of an image face can be printed, while an amount of a treatment liquid consumed is reduced. For that purpose, a group of pigment-based inks excellent in wettability with respect to the treatment liquid (small in contact angle with respect to the treatment liquid) are made relatively small in a proportion of the treatment liquid applied to a position to which the pigment-based ink concerned is applied. In contrast, a group of pigment-based inks poor in wettability (great in contact angle with respect to the treatment liquid) are made relatively great in a proportion of the treatment liquid applied to a position to which the pigment-based ink concerned is applied.
    • 提供了一种喷墨打印设备和喷墨打印方法,其中可以打印不消耗图像面的高质量图像,同时消耗的处理液量减少。 为此目的,使一组相对于处理液润湿性优异的颜料基油墨(相对于处理液体的接触角小)的比例相对较小, 应用颜料基油墨。 相比之下,在施加到所涉及的颜料类油墨的位置的处理液的比例中,使润湿性差(相对于处理液的接触角大)的一组颜料类油墨相对较大 。
