    • A printing apparatus and a printing method define an achromatic region and a chromatic region of image data. The image data is defined as an achromatic region when a difference between a maximum and a minimum values among R, G, B values corresponds to 1% to 10% of a range of values that R, G, B values are obtainable. In the achromatic region, the number of black and its derivative ink dots to be ejected per one pixel is 4 dots at the maximum. A chromatic region is defined as an area where does not satisfy the requirements of the achromatic region. In the chromatic region, the number of black and its derivative ink dots to be ejected per one pixel is 1 dots at the maximum.
    • 打印装置和打印方法限定图像数据的无彩色区域和彩色区域。 当R,G,B之间的最大值和最小值之间的差值对应于可获得R,G,B值的值的范围的1%至10%时,图像数据被定义为无色区域。 在消色差区域中,每个像素喷射的黑色及其导数墨点的数量最多为4点。 色区被定义为不满足无色区域要求的区域。 在彩色区域中,每1个像素喷射的黑色及其导数墨点的数量最多为1点。

    • When multilevel printing is performed by using a plurality of types of inks, which present different densities for similar colors when used for printing, and changing the types of inks and the numbers of ink droplets in printing each pixel, an ink distribution table which defines a combination of the types of inks and the numbers of ink droplets in correspondence with each gray level value is generated on the basis of input information associated with the relative densities of the respective inks. A combination to be used to print each pixel is selected on the basis of the ink distribution table, thereby printing a good grayscale image free from gray-level reversal and the like.
    • 当通过使用多种类型的油墨进行多层印刷时,其在用于印刷时呈现类似颜色的不同密度,并且在打印每个像素时改变油墨类型和墨滴数量,定义一个油墨分配表 基于与各个墨水的相对密度相关联的输入信息,生成与每个灰度值相对应的墨水类型和墨滴数量的组合。 基于墨水分配表选择用于打印每个像素的组合,从而打印不具有灰度级反转的良好灰度图像等。

    • A method for correcting image degradations due to nonejecting nozzles or kink ejection of nozzles without reducing a recording rate for an inkjet recording apparatus for recording images at high speed employing a one-pass recording system, in which an image is completed by one time scanning of a recording head relative to a recording medium, such as an inkjet recording apparatus using a full-line type recording head. When corrected data during head shading correction and nonejection complementing in image processing exceed a maximum value capable of being recorded, complementing is controlled with a different color corresponding to data-amount which exceeds the maximum value.
    • 一种用于校正由于不喷嘴引起的图像劣化或者在不降低使用一次记录系统的高速记录图像的喷墨记录装置的记录速率的情况下校正喷嘴的图像劣化的方法,其中通过一次扫描完成图像 相对于记录介质的记录头,例如使用全线型记录头的喷墨记录装置。 当在头部阴影校正和图像处理中的未补充补码中的校正数据超过能够被记录的最大值时,补码以对应于超过最大值的数据量的不同颜色进行控制。
