Movable Type Printing

Movable type printing — the technology of assembling individual reusable characters to create a printing surface — was invented in Song Dynasty China by Bi Sheng around 1040 CE, more than four centuries before Johannes Gutenberg's European version. It was one of several Chinese printing innovations that transformed the production and dissemination of knowledge.

Bi Sheng's movable type used ceramic characters that could be arranged in an iron frame, inked, and pressed onto paper. The technology was later refined using wood and metal type. However, movable type never fully replaced woodblock printing in China, primarily because the Chinese writing system's thousands of characters made typesetting enormously labor-intensive compared to carving a single woodblock for each page.

The impact of Chinese printing technology — both woodblock and movable type — was profound. It enabled the mass production of books, examination materials, paper money, and government documents. Buddhist texts, Confucian classics, and agricultural manuals reached audiences that hand-copying could never have served. When the technology reached Korea (which developed the world's first metal movable type around 1234) and eventually Europe, it transformed those societies even more dramatically. Gutenberg's press, using movable type with the much smaller Latin alphabet, ignited a communication revolution that reshaped European religion, politics, and culture.
