| 中文摘要: |
| 提出了一种新的分色算法。 方法首先对多色打印机进行色域分区,再将每个分区划分成若干个子空间,在每个子空间内运用最小二乘法建立多项式模型,对目标色度值进行分色时,搜索目标色度值所在最优子空间,求解对应的多项式方程,即可得到分色结果。 实验表明,这种分色算法具有较高的精度和稳定性,能够满足多色高精度印刷的要求。 |
| 英文摘要: |
| A new color separation method was proposed. Multi-color printer gamut was separated into partitions; every partition was divided into subspaces. Polynomial models were created in subspaces with least square method. Optimal subspace was found first when the targeting colorimetric value was in color separation. Separation result was obtained by solving polynomial equation. The experiment showed that this separation method performs well in accuracy and stability and satisfies the requirement of multi-color high-precision printing. |
