Woodblock printing had been known in China for centuries. It was innovations in type casting that made for Gutenberg's breakthrough of commercially printing. [1] Although using matrices was a technique known well before his time, Johannes Gutenberg adapted their use to a conveniently adjustable hand mould, enabling one to easily and accurately cast identical multiple instances of any character.
Matrices created by Jean Jannon around 1640. The Garamond typeface installed with most Microsoft software is based on these designs. [1] [2] [3]In the manufacture of metal type used in letterpress printing, a matrix (from the Latin meaning womb or a female breeding animal) is the mould used to cast a letter, known as a sort. [4]
Before computers were invented, and thus becoming computerized (or digital) typesetting, font sizes were changed by replacing the characters with a different size of type. In letterpress printing, individual letters and punctuation marks were cast on small metal blocks, known as "sorts," and then arranged to form the text for a page.
In physical typesetting, a sort or type is a block with a typographic character etched on it, used—when lined up with others—to print text. [1] In movable-type printing, the sort or type is cast from a matrix mold and assembled by hand with other sorts bearing additional characters into lines of type to make up a form, from which a page is printed.
A standard channel letter is a three-dimensional graphic sign element. Its channel is fabricated from sheet metal, most often aluminum since it will not rust. A flat sheet of aluminum is typically cut on a table by a computer-controlled router, laser, or water jet, based on a vector-based art file (.cdr, .eps, .ai, .scv, .sci, or .fs).
The finished letter punch is finally hardened to withstand the rigours of reproduction by striking. One counterpunch and one letterpunch are produced for every letter or glyph making up a complete font. Matrix The letterpunch is used to strike a blank die of soft metal to make a negative letter mould, called a matrix. Casting
