利用多项式回归法进行分色建模,结合灰平衡及兼色设置,获得了最终的分色结果,然后设计实验,从分色误差、分色精度方面进行了评价。 结果表明,该分色方法取得的分色效果较好,可以更加准确地进行颜色复制。

Combining gray component replacement and mid-color setting, a new seven-color separation model based on polynomial regression equation was proposed. The final color separation results were evaluated from color separation error, color separation precision. The results showed that the color separation effect is good; the method can make color reproduction more accurate.
