摘要： Provided is a dither pattern generation method so that a dot arrangement having excellent dispersibility can be obtained in low-gradation areas for single colors and for mixed colors. The dither pattern generation method generates dot patterns for low-gradation areas having threshold values 1 to S so that high dispersibility is obtained in a cyan dot pattern and a magenta dot pattern, and so that in a combined dot pattern made by combining these dot patterns there are no overlapping pixels. The dither pattern generation method then sets threshold values for a cyan dither pattern and a magenta dither pattern based on these generated dot patterns.

摘要： In an inkjet printing apparatus, the colors of ink dots are controlled to make it possible to change the colors of an image to be printed. More specifically, ink temperatures, ink permeation speeds, and the capillary occupancy rates of inks in a print medium are used to control a permeation area formed by performing printing with preceding cyan and subsequent magenta, thereby controlling the colors realized by the inks which are ejected in an overlapping manner.

摘要： In low-resolution processing (reduction processing) in which input image data is separated into character print data and image print data to generate print data of lower resolution than that of the input image data, if a plurality of pixels is simply reduction-processed to one pixel, color of a color image surrounding a character may change. In an image processing method, calculation for performing reduction processing so that the plurality of pixels in the input image data corresponds to one pixel in the print data is performed as follows. A ratio of using a pixel value of a character attribute pixel in the calculation is set to 0, or set smaller than a ratio of using a pixel value of an image attribute pixel. As a result, a change in the color of the color image surrounding the character can be prevented.
摘要翻译：在将输入图像数据分离为字符打印数据和图像打印数据以生成比输入图像数据的分辨率低的打印数据的低分辨率处理（缩小处理）中，如果简单地将多个像素进行缩小处理，一个像素，围绕字符的彩色图像的颜色可能会改变。在图像处理方法中，如下执行用于执行缩小处理使得输入图像数据中的多个像素对应于打印数据中的一个像素的计算。在计算中使用字符属性像素的像素值的比率被设置为0，或者设置为小于使用图像属性像素的像素值的比率。结果，可以防止围绕字符的彩色图像的颜色的变化。
