What it is

An integrated system of metal type cast in a hand mould, oil-based ink, and a screw press adapted from wine presses, enabling texts to be reproduced identically and cheaply. The 42-line Bible (c. 1455) inaugurates the culture of the printed book.

Movable-type precedents exist in China (Bi Sheng, 11th century) and Korea (Jikji, 1377), but the European system developed independently. Laurens Coster of Haarlem was claimed as the inventor by Dutch tradition, without solid evidence. Merged with «Movable-type metal printing press» (duplicate, 23 September 2026).
