基于喷墨绘图仪实际输出灰度的半色调技术和误差扩散方法

A Modified Halftone Technique and Error Diffusion on the Basis of Calculated Actual Grey of Jet Plotter

计算了喷墨绘图仪喷头的实际灰度，并基于这个实际灰度，改进了误差扩散方法和半色调技术．采用改进的方法后，输出图像的灰度和色彩很逼真。

This thesis calculats the actual grey of dot printed by jet plotter. On the basis of calculated actual grey, a modified error diffusion and halftone technique are researched. Based on the modified methods, the output picture is clear and the effect is better.
