    • Printing apparatus comprising a plurality of ink-jet head units for different densities of ink. Plural types of superimposition print data for superimposing different densities of ink in accordance with density are stored in an ink type distribution table. A predetermined image is printed on a print medium by using the plural types of superimposition print data, and density of the printed image is measured. Based on the measured density and a pixel value of original image data, the most optimum print data is selected from the plural types of superimposition print data stored in the ink type distribution table. By using the selected print data, driving data for printing the image is generated, using different densities of ink.
    • 印刷设备包括用于不同密度油墨的多个喷墨头单元。 油墨类型分布表中存储有用于根据密度叠加不同密度的油墨的多种类型的叠加打印数据。 通过使用多种类型的叠加打印数据将预定图像打印在打印介质上,并且测量打印图像的浓度。 基于测量的浓度和原始图像数据的像素值,从存储在墨水分布表中的多种类型的叠加打印数据中选择最佳打印数据。 通过使用所选择的打印数据,产生用于打印图像的驱动数据,使用不同密度的墨水。
