| 目的 为减小凹版印刷过程中套印误差、提高印刷质量。方法 分析凹版印刷产生误差的主要原因，基于模糊控制设计一种多色套准控制系统。论述基于图像处理的套印误差检测原理。根据多色套印的生产需求，设计一种模糊比例-积分-微分(PID)控制器。利用模糊推理，该控制器可对PID参数进行自适应调整，进而实现高精度、高速度印刷。最后，采用数字信号处理器(DSP)搭建控制系统架构，并进行实验研究。结果 实验结果表明，套印偏差最大值只有0.018 mm，远小于行业标准;套印偏差检测速度明显大于印刷速度，可确保印刷过程的实时性。结论 所述多色套准控制系统具有精度高、速度高等特点，可满足印刷、包装等相关行业的要求。 |

| In order to reduce overprinter error and improve printing quality in intaglio printing process, the main causes of errors in intaglio printing ware analyzed and a multi-color alignment control system was designed based on fuzzy control. The principle of overprinter error detection based on image processing was discussed. According to the production demand of multi-color overprinter, a fuzzy proportional-integral-differential (PID) controller was designed. By using fuzzy reasoning, the PID parameters couble be adjusted adaptively, then a high precision and speed printing couble also be realized. Finally, the architecture of the control system was built by digital signal processor (DSP) and the experimental research was carried out. The experimental results show that the maximum deviation of over-printer is only 0.018 mm, which is far less than the industry standard. The detection speed of overprint deviation is obviously higher than that of printing, which can ensure the real-time performance of printing process. The multi-color registration control system based on DSP has the characteristics of high precision and high speed, which can meet the requirements of printing, packaging and other related industries. |
