With the increasingly wide range of inkjet technology, in order to meet the social needs of high-speed and high-precision inkjet printers, this paper presents a self-designed main control system for high-speed color inkjet printer combined with software-, electrical、 mechanical and ARM processor. This system receives commands and image data from PC, detects and controls each movement of the system, synchronizes motion and nozzle' s spray, meanwhile, transmits image data to the nozzle control panel. After research and testing, the machine can improve the full color high-definition screen printing speed in the market-leading level, what's more, has produced good e-conomic benefits.%随着喷绘技术应用的日益广泛,为了满足社会对高速高精度喷绘机的需求,基于ARM处理器结合软件、电子、机械等技术,自行研发了一套高速彩色喷绘机主控制系统；该系统接收上位机的控制命令和图像数据,检测并控制系统中的各个运动环节,同步运动与喷头的喷射,并将喷头需要的图像数据传输到喷头控制板上；实验证明,系统能够很好地控制其运行状态,水平运动可以精确到720dpi,并产生了较好的经济效益.
