    • When printing image data obtained by an input device, the present invention is intended to effectively utilize the color reproduction area of the printer. An image data processing method of the present invention comprises the steps of scale-down shifting a first color space point outside a maximum color reproduction area of an output unit to a second color space point within the maximum color reproduction area of the output unit; computing an amount of shift by which the first color space point is shifted to the second color space point; converting the second color space point to a third color space point within a color reproduction area smaller than the maximum color reproduction area of the output unit; and outputting an image to the output unit using image data obtained by scale-up shifting the third color space point to a fourth color space point within the maximum color reproduction area of the output unit based on the computed shift amount.
    • 当打印由输入装置获得的图像数据时,本发明旨在有效地利用打印机的色彩再现区域。 本发明的图像数据处理方法包括以下步骤:将输出单元的最大色彩再现区域之外的第一色彩空间点向下移位到输出单元的最大色彩再现区域内的第二色彩空间点; 计算第一颜色空间点移动到第二颜色空间点的偏移量; 将所述第二颜色空间点转换为比所述输出单元的最大颜色再现区域小的颜色再现区域内的第三颜色空间点; 并且使用通过基于所计算的移位量将所述第三颜色空间点向所述输出单元的最大颜色再现区域内的第四颜色空间点进行放大而将所获得的图像数据输出到所述输出单元。

    • An ink-jet recording apparatus and an ink-jet recording method which provide an image featuring reduced graininess and good gradation. A plurality of inks of different densities are used to obtain a halftone image with controlled graininess. An ink which has low penetrability on a recording medium and which controls the diffusion of dots is used as an ink with a relatively high density. An ink which has high penetrability and which permits easy diffusion of dots is used as an ink with a relatively low density. The present invention also provides a characteristic recorded article to be formed by a plurality of dots having different penetrabilities on a recording medium. Among a plurality of inks with different densities, the inks of the same color category are grouped and held in an ink container and are divided in the container by the ink density. This configuration makes it possible to make the containers smaller and minimize the number of containers.
    • 一种喷墨记录装置和喷墨记录方法,其提供具有降低的颗粒度和良好灰度的图像。使用不同密度的多种油墨来获得具有受控颗粒度的半色调图像。 使用在记录介质上具有低穿透性并且控制点扩散的油墨作为具有较高密度的油墨。 作为具有较低密度的油墨,使用具有高渗透性并且允许点容易扩散的油墨。 本发明还提供了一种通过在记录介质上具有不同穿透性的多个点形成的特征记录制品。在具有不同密度的多种油墨中,相同颜色类别的油墨被分组并保持在油墨容器中, 通过油墨密度在容器中分配。 这种构造使得可以使容器更小并且使容器的数量最小化。
