摘要
现代彩色静电照相数字印刷出现以不同半色调算法复制彩色图像的趋势。影响最终印刷图像噪声表现的因素包括数字半色调算法、纸张类型以及墨粉颗粒形状和尺寸的非均匀性等,其中半色调算法决定网点结构,成为本文讨论的重点。
Trends to reproduce color images using different halftone algorithms have been emerged in modem color xerographic digital printing area. Noise existed in final printed images will be effected by various factors, such as digital halftone algorithms, types of paper, as well as non-tmiformity of shape and size of toner particles. Screen structures will be determined by halftone algorithms, on which discussions were be focused in this paper.
