China's traditional printing industry has developed rapidly but abnormally, with low profits, serious information asymmetry, poor business communication, acquaintance trading and so on. In recent years, e-books have suppressed the printing of books and periodicals, the wind of clean government has suppressed the packaging printing, and digital printing has occupied the personalized printing. Our traditional printing industry has overcapacity, and the national average construction time is only 50%, with huge differences between the north and the south. It can be predicted that the Internet of printing industry and even the Internet of manufacturing industry will be the trend! Network channels are more convenient and convenient, saving resources, protecting the environment and saving manpower. For this, the traditional printing industry also needs to change as soon as possible.
