Matrix (printing)
In hot metal typesetting, a matrix (often abbreviated to "mat") is a mold for casting a letter, known as a sort, used in letterpress printing.[1]
In letterpress typography the matrix of one letter is inserted into the bottom of a hand mould, the mould is locked and molten type metal is poured into a straight-sided vertical cavity above the matrix. When the metal has cooled and solidified the mould is unlocked and the newly-cast metal sort is removed, ready for composition with other sorts. The matrix can then be reused to produce more copies of the sort.[2]
In continuous casting and composition casting typography, the mats for a complete font are loaded into a matrix-case and inserted into a casting machine, which casts the required sorts for a page composition automatically.
