中文摘要：

喷墨印刷多级控制技术通过控制微小墨滴的大小和落点,实现多级输出,会对颜色再现过程产生影响。设计色靶并利用不同级别控制输出,从色域和层次2个方面对多级控制产生的影响进行了分析。研究表明：级别越高,形成的色域越大;在亮调区域,级别越低,可以表现的颜色层次越多;在中暗调区域,级别越高,可以表现的颜色层次越多。

英文摘要：

Multi-level control technology of inkjet printing achieves multi-level output by controlling the size and placement of tiny ink droplets. It has influence on the color reproduction process. Color target was designed and different levels output were carried out. The influence of multi-level output was analyzed from the aspects of color gamut and color gradation. The results showed that the higher the level, the larger the gamut ; the lower the level, the more levels of the color in the bright tone area; the higher the level, the more levels of the color can be reproduced in the middle and dark tone area.
