Copper movable type printing originated in China at the beginning of twelfth century. It was used in large scale printing of paper money issued by the Northern Song dynasty.
Around 1230, Koreans invented a metal type movable printing using bronze. The Jikji, published in 1377, is the earliest known metal printed book. Type-casting was used, adapted from the method of casting coins. The character was cut in beech wood, which was then pressed into a soft clay to form a mould and bronze poured into the mould and the type was finally polished.[10]
Around 1450, Johannes Gutenberg introduced what is regarded as the first modern movable type system in Europe (see printing press), along with innovations in casting the type based on a matrix and hand mould. Gutenberg was the first to create his type pieces from an alloy of lead, tin, and antimony – the same components still used today.
