Movable type (US English; moveable type in British English) is the system and technology of printing and typography that uses movable components to reproduce the elements of a document (usually individual alphanumeric characters or punctuation marks) usually on the medium of paper.
The world's first movable type printing technology for printing paper books was made of porcelain materials and was invented around AD 1040 in China during the Northern Song Dynasty by the inventor Bi Sheng (990–1051).[1] The oldest extant book printed with movable metal type, Jikji, was printed in Korea in 1377 during the Goryeo dynasty.
The diffusion of both movable-type systems was, to some degree, limited to primarily East Asia. The development of the printing press in Europe may have been influenced by various sporadic reports of movable type technology brought back to Europe by returning business people and missionaries to China.[2][3][4] Some of these medieval European accounts are still preserved in the library archives of the Vatican and Oxford University among many others.[5]
Around 1450, Johannes Gutenberg introduced the metal movable-type printing press in Europe, along with innovations in casting the type based on a matrix and hand mould. The small number of alphabetic characters needed for European languages was an important factor.[6] Gutenberg was the first to create his type pieces from an alloy of lead, tin, and antimony—and these materials remained standard for 550 years.[7]
For alphabetic scripts, movable-type page setting was quicker than woodblock printing. The metal type pieces were more durable and the lettering was more uniform, leading to typography and fonts. The high quality and relatively low price of the Gutenberg Bible (1455) established the superiority of movable type in Europe and the use of printing presses spread rapidly. The printing press may be regarded as one of the key factors fostering the Renaissance[8] and due to its effectiveness, its use spread around the globe.
The 19th-century invention of hot metal typesetting and its successors caused movable type to decline in the 20th century.
Modern, factory-produced movable type was available in the late 19th century. It was held in the printing shop in a job case, a drawer about 2 inches high, a yard wide, and about two feet deep, with many small compartments for the various letters and ligatures. The most popular and accepted of the job case designs in America was the California Job Case, which took its name from the Pacific coast location of the foundries that made the case popular.[48]
Tiny differences in type-height can cause quite bold images of characters.
At the end of the 19th century there were only two typefoundries left in the Netherlands: Johan Enschedé & Zonen, at Haarlem, and Let At the end of the 19th century there were only two typefoundries left in the Netherlands: Johan Enschedé & Zonen, at Haarlem, and Lettergieterij Amsterdam, voorheen Tetterode. They both had their own type-height: Enschedé: 65 23/24 points Didot, and Amsterdam: 66 1/24 points Didot - enough difference to prevent a combined use of fonts from the two typefoundries: Enschede would be too light, or otherwise the Amsterdam-font would print rather bold. A perfect way of binding clients.[49]
In 1905 the Dutch governmental Algemeene Landsdrukkerij, later: "State-printery" (Staatsdrukkerij) decided during a reorganisation to use a standard type-height of 63 points Didot. Staatsdrukkerij-hoogte, actually Belgium-height, but this fact was not widely known[by whom?].

Traditionally, the capital letters were stored in a separate drawer or case that was located above the case that held the other letters; this is why capital letters are called "upper case" characters while the non-capitals are "lower case".[51]
Compartments also held spacers, which are blocks of blank type used to separate words and fill out a line of type, such as em and en quads (quadrats, or spaces. A quadrat is a block of type whose face is lower than the printing letters so that it does not itself print.). An em space was the width of a capital letter "M" – as wide as it was high – while an en space referred to a space half the width of its height (usually the dimensions for a capital "N").
Individual letters are assembled into words and lines of text with the aid of a composing stick, and the whole assembly is tightly bound together to make up a page image called a forme, where all letter faces are exactly the same height to form a flat surface of type. The forme is mounted on a printing press, a thin coating of viscous ink is applied and impressions made on paper under great pressure in the press. "Sorts" is the term Traditionally, the capital letters were stored in a separate drawer or case that was located above the case that held the other letters; this is why capital letters are called "upper case" characters while the non-capitals are "lower case".[51]

Sometime it is erroneously stated that printing with metal type replaced the earlier methods. In the industrial era printing methods would be chosen to suit the purpose. For example, when printing large scale letters in posters etc. the metal type would have proved too heavy and economically unviable. Thus, large scale type was made as carved wood blocks as well as ceramics plates.[52] Also in many cases where large scale text was required, it was simpler to hand the job to a sign painter than a printer.
Images could be printed together with movable type if they were made as woodcuts or wood engravings as long as the blocks were made to the same type height. If intaglio methods, such as copper plates, were used for the images, then images and the text would have required separate print runs on different machines.
