使用3D-LUT的黑色生成算法

Black Generation Algorithm Using 3D-LUT

针对高品质彩色打印的应用需求,提出一种改进的GCR黑色生成算法。首先提出生成打印样本集的改进方法,然后介绍了使用3D-LUT建立打印机模型时的关键问题,最后给出了传统GCR方法和新方法的结果对比。相比传统方法,新方法明显增大了低明度部分色域,提高了打印机色彩再现能力减小了校正误差。,

For the need of high quality color print, a kind of black generation algorithm on the basis of improving the GCR is presented. Firstly, this paper presents the improved generation method of the print sample, then introduces the key problem when using the 3D-LUT to build the printer model, finally the results between the traditional method and the new one are presented. Compared with the traditional GCR method, the new method obviously enlarges the printer gamut in the low lightness, improves the color reproduction capability of the printer, and reduces the calibration error. ;;;
