Gutenberg's printing press
- Where
- Mainz, Germany. This replica is in the printing museum at El Puig, near Valencia, Spain
- When
- 1440s; the Gutenberg Bible was printed in the 1450s
- Who
- Johannes Gutenberg, Germany
- Made with
- A wooden screw press, metal letters cast in a hand mould, and oil-based ink
Gutenberg cast thousands of small metal letters in a mould, all exactly the same size. A printer set them in lines to make a page, inked them, and pressed paper onto them with a wooden screw press, like the presses farmers used. After printing, the letters were taken apart and reused for the next page, which is why it is called movable type. His Bible, printed in Mainz in the 1450s, is also called the 42-line Bible because most of its pages have 42 lines. Books became far cheaper and faster to make, and new ideas spread across Europe.
Spot it by
A tall wooden frame with a big screw and a pulling bar, a flat bed that slides in under it, and a hinged frame to hold the paper.Remember
Gutenberg, 1440s: letters you can move, in a press you screw down.Don't confuse
Movable type was not new: it had been used in East Asia centuries earlier. What Gutenberg added was a complete system, from casting type to the press and the ink, that made printing fast.
