The Origin of Printing
Printing has always been one of the important technologies that humans rely on to disseminate knowledge and information. Its invention and promotion have had a tremendous impact on the progress of human civilization and society as a whole. With printing technology, humans were able to replicate text, graphics, and other information on a large scale, breaking through regional limitations to disseminate and inherit information recorded in various scientific and cultural fields.
Printing is the pride of China. We all know that it is one of the the Four Great Inventions in ancient China and the treasure left by our ancestors. The invention of printing technology was not obtained by chance. It is the result of the long-term accumulation of culture, material resources, and skills of the Chinese nation, and is a long process. Like all scientific and technological developments, it is precisely because of human activities and social needs that printing technology has been gradually invented, developed, and improved
The early human seals, stone carvings, and rubbings were the root of the development of printing technology. Their existence, integration, and gradual development of their respective technologies led to the development of seals, stone carvings, and rubbings in printing
1. Seal
Ancient seals can be seen as a medium that carries certain text and graphics, and can be disseminated as long as the user is willing
The uneven surface of the seal is engraved with different shapes and characters. Users can apply various pigments or ink on it and transfer the graphics and characters onto other media such as paper through transfer printing. The process of transferring graphics and text through third-party means is the key to completing printing and the foundation for the development of most printing technologies. In the Northern Qi Dynasty (550577 AD), someone made the seals used for stamping official documents very large, making it easier to record more information. This was like a small carved version, and each stamping process was like a small-scale printing.
2. Stone carvings
From a printing technology perspective, stone carvings are like enlarged versions of seals. Seals only copy simple graphic and textual information, and there are also many components for personal use. Stone carvings, on the other hand, use larger stones to accommodate more information needed. Ancient people had no other recording tools, and could only carve some information that needed to be preserved for a long time for reading, rubbing and copying. In terms of technical principles, there is a direct inheritance relationship between stone carvings and seals. However, from the perspective of cultural development, stone carvings have a greater pioneering significance for printing than seals, as a small seal cannot carry a lot of information.
By now, everyone must understand that the culture of the ancient Chinese civilization has been inherited and developed, and seals, stone carvings, and rubbings are no exception. Their long-term use has provided technical inspiration for the further development of printing technology.
