| 中文摘要: |
| 以平版印刷方式配制专色油墨为例，建立了以库贝尔卡-芒克理论为基础的三刺激权重单常数配色数学模型，然后利用Matlab软件对其和Allen提出的常规三刺激配色算法进行程序化设计。通过配色实验证实了三刺激权重单常数配色法适用于胶印专色油墨配色，且与常规的三刺激配色相比，减少了迭代修正次数，得到的匹配色样与目标色样间的色差值更小，同色异谱程度有较小幅度的降低，表明新建的三刺激权重配色模型具备了较高的配色精度。 |
| 英文摘要: |
| Tristimulus weights single-constant mathematical model of computer color matching of spot-color printing ink used in offset printing was established based on Kubelka-Munk theory. The new mathematical model and Allen’s conventional tristimulus mathematical model were programmed using Matlab software. Computer color matching experiments showed that the tristimulus weights single-constant mathematical model is applicable to offset printing spot-color ink; the number of iterative correction is reduced; color difference is smaller, and metamerism degree is reduced compared with the conventional tristimulus mathematical model. It was concluded that the new mathematical model has higher color matching accuracy. |
