摘　　要：图像输出设备色彩特性文件描述了图像设备的色彩再现能力,是图像复制色彩管理流程中颜色转换的关键。本文通过立方体插值法实现颜色空间转换,应用最大分区法与色域裁剪法实现色域匹配,设计实现了彩色数字喷墨打印机的色彩特性化方法。在此基础上,开发了彩色数字喷墨打印机色彩特性文件生成软件。最后,从色域、中性灰再现能力及色差三个方面对生成的打印机色彩特性文件进行评价。实验结果表明,基于本文设计的彩色数字喷墨打印机色彩特性化方法生成的色彩特性文件可以满足图像复制色彩管理流程中颜色转换的精度要求。The ICC profile of image output device which describes the color reproduction capabilities of the image output de- vice is the key of color conversion in the process of color management. In this paper, the cube interpolation method was se- lected to convert the color space. The segment maxima gamut boundary descriptor method and color gamut clipping method were used to realize color gamut mapping. The color characterization method for digital color inkjet printer was designed and implemented. Based on the method, the ICC profiles generation software for digital color inkjet printers was developed. Fi- nally, the ICC profiles of color printers were evaluated with color gamut, neutral gray balance capability and color differ- ence. The experiment results showed that the ICC profiles created by the generation software can meet the precision require- ments of color conversion in color management.
