摘　　要：阐述了彩色静电绘图机产生套色误差的主要原因 ,即由走纸轴的加工误差、装配误差和打印纸受潮后伸长造成的 ,在此基础上提出了一种数字动态检测套色误差和校正该误差的方法 ,即利用电荷耦合器件检测打印纸的横向偏移和纵向伸长量 ,利用一行打印数据前增加或减少零的位数校正横向误差 ,改变走纸速度校正纵向误差 .经测试证明 ,此方法不但提高了套色精度 ,而且也增强了抗干扰的能力 ,且具有结构简单 。This paper deals with the main causes of the Chromatography errors generated in Color Electrostatic Plotters, which include the machining error, assemble error and the extension of paper due to humidification, on the basis of which a digital dynamic detecting and correcting method is put forward. In this method the CCD component is used to detect the horizontal offset and vertical extension of paper, with the horizontal error corrected by increasing or decreasing numbers of zero bit at the head of one print data line, and the vertical error corrected by changing the speed of advance paper. It is proved that this method has the advantages of high chromatography precision, strong anti jamming ability, simple structure and high correct speed
