摘要
基于绿噪声技术,提出一种大幅面二级喷墨打印设备输出多级半色调图像的新方法,其中采用阈值调制技术设计了多级误差扩散方法较好地解决了伪轮廓问题。实验表明使用该方法大幅面二级喷墨打印设备输出多级半色调图像效果良好。
In order to print multitoning image with large format bilevel inkjet printer, a new method based on the technique of green noise was proposed. Multiscale error diffusion method was designed by the technique of threshold modulation, and then the false contouring of the output was removed. The experimental results show that the multitoning image got is favorable.
