| 中文摘要: |
| 基色的筛选与优化是多基色色彩高保真复制的关键技术。以显示器色域为扩展目标，提出了印刷色彩高保真复制基色筛选算法。研究表明，传统印刷所复制的红绿蓝在中间调红色、亮调绿色、暗调蓝色区域，相比显示器色彩再现具有最显著的不足，提出了以淡红色（Lr）、淡绿色（Lg）为新基色，与传统C，M，Y，K组成六色色彩高保真复制的基色向量，并筛选出了符合要求的Lr，Lg基色油墨。使用色彩预测模型对新的基色组合进行了色彩复制和色域的仿真。结果表明，提出的基色筛选机制所得到的六基色，能够有效扩大印刷复制的色域。 |
| 英文摘要: |
| Colorant selection and optimization is an important issue for high-fidelity color reproduction. A new colorant selection algorithm for high-fidelity color reproduction was put forward to offset the maximum color gamut gap between display and print. Our study showed that the maximum gamut gaps of red, green, and blue between display and print lie in the middle tone of red, bright tone of green and dark tone of blue. Light red and light green was proposed, in addition to traditional CMYK, as the new six primary colorants. The light red and light green ink were selected, the gamut were simulated by computer. Results showed that the new six primary colorants we proposed can extend the printing gamut efficiently. |
