    • The conventional print-controlling apparatus performs printing with CMY inks and additional inks having a lower lightness than CMY inks, which are mixed in a specific ratio when ejected from the print head, so that colors in the entire range from low to high lightness are expressed. Unfortunately, chromatic color inks differing in hue from CMY inks have a low lightness or a high density, and this leads to poor granularity in the region of high lightness. This disadvantage is eliminated if color conversion is accomplished by using the granularity improvement LUT 15c that limits the deposition of RV inks. In this way it is possible to limit the ejection of RV inks in the region of high lightness and to improve the ink granularity in the region of high lightness.
    • 常规的打印控制装置使用CMY墨水和具有比CMY墨水更低的亮度的附加墨水进行打印,这些墨水从打印头喷射时以特定比例混合,使得从低到高亮度的整个范围内的颜色被表达 。 不幸的是,色调不同于CMY墨水的彩色墨水具有低亮度或高密度,这导致在高亮度区域的差的粒度。 如果通过使用限制RV油墨沉积的粒度改善LUT15c来实现颜色转换,则消除这个缺点。 以这种方式,可以在高亮度区域限制RV油墨的喷射并且提高高亮度区域中的油墨粒度。

    • The invention provides a printing method of printing on a printing medium. The method includes: generating dot data that represents state of dot formation at each print pixel of a print image to be formed on the printing medium by performing a halftone process on image data that represents an input tone value of each pixel making up an original image; and generating the print image by forming dots on each of the print pixels according to the dot data. The halftone process determines the state of dot formation by using a dither matrix that stores a plurality of threshold values, the plurality of threshold values being used for determining state of dot formation at each of print pixels of the print image to be formed on the printing medium according to an input tone value. The dither matrix is a matrix that stores each of the plurality of threshold values in each element such that a mutual difference in dot density formed at each predetermined print pixel group according to each input tone value falls within a predetermined range. The predetermined print pixel group is a cluster of plural print pixels corresponding to each of a plurality of element groups that are created by dividing the dither matrix into preset numbers of elements.
    • 本发明提供一种在打印介质上进行打印的打印方法。 该方法包括:通过对构成原始图像的每个像素的输入色调值的图像数据执行半色调处理,生成表示要在打印介质上形成的打印图像的每个打印像素处的点形成状态的点数据 ; 以及通过根据点数据在每个打印像素上形成点来生成打印图像。 半色调处理通过使用存储多个阈值的抖动矩阵来确定点形成的状态,所述多个阈值用于确定在打印时要形成的打印图像的每个打印像素处的点形成的状态 介质根据输入色调值。 抖动矩阵是将每个元素中的多个阈值中的每一个存储在每个元素中的矩阵,使得根据每个输入色调值在每个预定打印像素组处形成的点密度的相互差异落在预定范围内。 预定的打印像素组是通过将抖动矩阵分割成预定数量的元素而创建的多个元素组中的每一个对应的多个打印像素的簇。

    • The invention provides a printing method of performing printing on a print medium. The method includes: generating dot data representing a status of dot formation on each of print pixels of a print image to be formed on the print medium, by performing a halftone process on image data representing a input tone value of each of pixels constituting an original image; generating the print image by combining forward pass dots with backward pass dots in a common printing area in such a manner that each main scan line includes both the forward pass dots and the backward pass dots, the forward pass dots being formed on a plurality of pixels of a first pixel group in a forward pass of main scan of a print head, the backward pass dots being formed on a plurality of pixels of a second pixel group in a backward pass of main scan of the print head. The generating dot data includes setting a halftone process condition for reducing a deterioration of image quality due to a positional misalignment between the forward pass dots formed in the first pixel group and the backward pass dots formed in the second pixel group.
