    • A second printing control unit is provided. If the setting information is the information of setting for avoiding the use of Cl ink (uncolored ink), the second printing control unit refers to the same color conversion table as is used by a first printing control unit. Thereby the second printing control unit color-converts input image data into image data comprising gradation data corresponding to at least the amounts of colored inks in C, M, Y, R, V, and K consumed. The second printing control unit can carry out such control as to cause a printer (printing device) to use only the C, M, Y, R, V, and K colored ink and print a print image, using the image data.
    • 提供第二打印控制单元。 如果设置信息是用于避免使用Cl油墨(未着色油墨)的设置的信息,则第二打印控制单元参考与第一打印控制单元使用的相同的颜色转换表。 由此,第二打印控制单元将输入图像数据进行颜色转换为包括至少与消耗的C,M,Y,R,V和K中的彩色墨水量对应的灰度数据的图像数据。 第二打印控制单元可以执行使打印机(打印装置)仅使用C,M,Y,R,V和K彩色墨水并使用图像数据打印打印图像的控制。

    • Utilizing an ink set that includes a plurality of chromatic primary color inks that, when used in combination, can reproduce achromatic color, and at least one spot color ink of hue different from any of the plurality of chromatic primary color inks. Color to be reproduced on a print medium according to any one input color is termed “reproduction color”, and the combination of ink quantities in the ink set for reproducing the reproduction color on the print medium is termed the “color separation ink quantity set.” The ink quantity of the spot color ink included in the color separation ink quantity set is adjusted in accordance with a lightness parameter value which is correlated to lightness of reproduction color, so as to reduce ink quantity at a rate of change greater than the rate of change of the lightness parameter in the direction of increasing brightness.
    • 利用包括多个彩色原色油墨的油墨组合,当组合使用时,可以再现无色颜色,以及至少一种不同于多种彩色原色油墨中的任何一种色相的专色油墨。 根据任何一种输入颜色在打印介质上再现的颜色被称为“再现颜色”,并且用于在打印介质上再现再现颜色的油墨组中的油墨量的组合被称为“分色油墨量组”。 “根据与再现颜色的亮度相关的亮度参数值来调节包括在分色油墨量组中的专色油墨的油墨量,以便以大于比率的变化率降低油墨量 亮度参数在增加亮度的方向上的变化。
