摘　　要： 为测量高速运动状态下印刷机滚筒表面位移偏差,采用了黑白条形码编码为基础的光电检测方法,设计并实现了一套非接触式光电检测系统。通过精确设计的检测条形码,得到了系统在高速测量情况下的工作状态和测量精度,测量误差低于±3μm。结果表明,系统工作稳定可靠,检测速度快,满足套印误差测量的精度要求,为有效解决印刷机套印误差提供了全新的技术手段。 A photoelectric detection method based on black-white bar code and modem photoelectric detection technology was selected for measuring the displacement deviation of printing press cylinder surface in high-speed motion state. A highprecision non-contact photoelectric detection system was designed and implemented. The accurate testing barcode was used to verify work status and measurement accuracy of the system in high-speed measurement state for assessing the quality of the system, low measurement error less than ＋ 3μm. The given experiment results indicate that： the system has stable working condition, high measurement speed, meeting the accuracy requirements of measuring the overprint deviation, and giving a new technological means to effectively solving overprint deviation.
