In order to produce large-size laser anti-counterfeiting packaging materials, a high-speed laser platesetter was developed. The laser platesetter working in dynamic exposure mode overcomes the effect of influencing factors on work station positioning accuracy. High speed and high precision positioning was realized by using industrial computer as host computer, motion controller PMAC and MCU STC12C5410AD as lower machine, and linear motor technology. Working speed is improved more than 10 times, which effectively improves the production efficiency of holographic plate.
