喷墨打印机驱动程序中的色彩控制应用

Color Control of Ink-jet Printing Driver

目的以EPSON Stylus R270彩色喷墨打印机为案例,对打印驱动程序中的色彩控制进行研究和分析。方法测试打印驱动程序中不同"打印质量"和"色彩模式"所能再现的色域范围,应用Adobe Photoshop软件设计驱动程序级和应用程序级2种色彩管理方案,并测试不同方案的颜色匹配效果。结果高打印质量选项对应的色域范围在绿色区域明显大于低质量选项;在色彩模式方面,"Adobe RGB"模式在绿色区域的再现能力要强于"Epson标准"和"Epson鲜明"模式,而后2种模式在红蓝区域的再现效果较好。在颜色管理方面,应用程序级颜色复制流程的色彩匹配精度较高,比驱动程序级颜色复制流程小了近4个色差单位。结论在今后应用中可根据打印图像的颜色特征和质量要求合理设置打印参数并设计打印流程,以求获得满意的颜色复制效果。

The work aims to research and study the color control of printing driver, with EPSON Stylus R270 color ink-jet printer as an example. The gamut volume reproduced by different ＂printing qualities＂ and ＂color modes＂ in the printing driver were tested. Adobe Photoshop software was applied to design driver-level and application-level color management schemes and the color matching effects of different schemes were tested. As a result of the study, the gamut volume of green part corresponding to high printing quality option was larger than that corresponding to low printing quality. As for color modes, the reproduction ability of ＂Adobe RGB＂ mode of green part was stronger than that of ＂EPSON Standard＂ mode and ＂EPSON Vivid＂ mode, but the latter two modes had a better ability to reproduce the red-blue gamut part. As for color management, the color matching precision in color reproduction workflow based on application was higher, so its color matching precision was higher than that based on print driver （△E≈4）. In order to obtain the desired color reproduction effects, proper printing parameters can be set and printing workflow can be designed in future application according to color characteristics and quality requirements of printed image.
