As one of the the Four Great Inventions in ancient China, printing has made indelible contributions to the spread of human civilization and culture. In 1439, Gutenberg, Germany, manufactured a wooden relief printing machine. Although this vertical spiral hand wrench printing machine had a simple structure, it remained in use for 300 years; In 1812, Konich of Germany made the first round press relief printing machine; In 1847, Hoy of the United States invented the rotary printing press; In 1900, it was made into a six color rotary printing machine; In 1904, Rubel of the United States invented the offset printing press.

With the development of technology, modern printing machines are generally composed of plate mounting, ink coating, embossing, and paper feeding. The working principle is: first, the text and images to be printed are made into a printing plate, installed on a printing machine, and then manually or by a printing machine, ink is applied to the area where the text and images are present on the printing plate. Then, directly or indirectly, the ink is transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wooden boards, glass, and ceramics) to replicate the same text and images as the printing plate.
