What are the four stages of printing development?

Printing in China has a long history and is widely spread. It is an important part of China culture; It germinated with the birth of China culture and evolved with the development of China culture. In terms of origin, it has experienced four historical periods: origin, ancient times, modern times and contemporary times, with a development course of more than 5,000 years. In the early days, in order to record events and spread experience and knowledge, people created early written symbols and sought the media to record these words. Limited by the means of production at that time, people can only use natural objects to record words and symbols. For example, Chinese characters are carved on natural materials, such as rock walls, leaves, animal bones, stones and bark. Because written materials are very expensive, only important events can be recorded briefly. Most people's experience can only be spread orally, which seriously affects the development of social culture.

The invention of printing greatly changed this situation. People's accumulated experience can be written in words and copied and disseminated in large quantities. This is a great change in social and cultural views, thus giving more people the opportunity to learn.

With the passage of time and the development of social and cultural undertakings, the hand-carved technology for carving, printing and printing characters, as well as the bark cloth printing technology, which appeared in the Neolithic age in China, gradually developed from simple and rough carving to complex, exquisite and standardized carving. By the Shang and Yin Dynasties before 1 1 century BC, it had been used for carving Oracle characters. During the Western Zhou Dynasty, the carving technology was combined with the ancient smelting technology, and bronze vessels for casting or carving characters appeared and developed. From the Eastern Zhou Dynasty to the Qin Dynasty, the wind of stone carving became more and more popular, which made this ancient hand-carved technology make great progress in quantity and quality, and took the lead in opening the seal. He has made great contributions to the development of China's cultural undertakings. At the same time, it also creates opportunities and conditions for the further development and perfection of hand-carved technology. Since the Qin and Han Dynasties, the stamping, clay sealing and die printing of brick and tile belong to the expansion of the application field of manual carving and the wide application of transfer printing and reproduction. As for the further development of rubbing and fabric printing, it is essentially the printing in the embryonic form.
