    • An object of the present invention is to provide a recording apparatus in which the occurrence of smearing and bleeding in the borders between black and color pixels can be reduced, and in which high-quality black characters and black images can be recorded. Black adjacent pixels, in which pixels adjacent to their periphery are black pixels, and color adjacent pixels, which are composed of pixels wherein pixels adjacent to their periphery are recorded with colored ink, are extracted from each pixels constituting a black image, and color ink data is created so that color ink is applied according to a certain ratio for the black adjacent pixels or color adjacent pixels. The occurrence of smearing and bleeding is suppressed by performing recording according to original data and the created color ink data.
    • 本发明的一个目的是提供一种记录装置,其中可以减少在黑色和彩色像素之间的边界上发生污迹和渗色,并且可以记录高质量的黑色字符和黑色图像。 从构成黑色图像的每个像素中提取黑色相邻像素,其中与其周围相邻的像素是黑色像素,以及颜色相邻像素,其由与其周边相邻的像素的像素组成,并且彩色墨水 创建数据,使得根据黑色相邻像素或颜色相邻像素的一定比例施加彩色墨水。 通过根据原始数据和所创建的彩色墨水数据进行记录来抑制涂抹和渗色的发生。
