"Johannes Gutenberg is famous for having designed and built the first printing press to incorporate movable type and mechanized inking and for using his invention to produce the Gutenberg Bible." -- brittanica.com "Gutenberg's technique of making movable type remains unclear. In the following decades, punches and copper matrices became standardized in the rapidly disseminating printing presses across Europe. Whether Gutenberg used this sophisticated technique or a somewhat primitive version has been the subject of considerable debate. "In the standard process of making type, a hard metal punch (made by punchcutting, with the letter carved back to front) is hammered into a softer copper bar, creating a matrix. This is then placed into a hand-held mould and a piece of type, or "sort", is cast by filling the mould with molten type-metal; this cools almost at once, and the resulting piece of type can be removed from the mould. The matrix can be reused to create hundreds, or thousands, of identical sorts so that the same character appearing anywhere within the book will appear very uniform, giving rise, over time, to the development of distinct styles of typefaces or fonts. After casting, the sorts are arranged into type cases, and used to make up pages which are inked and printed, a procedure which can be repeated hundreds, or thousands, of times. The sorts can be reused in any combination, earning the process the name of "movable type. "The invention of the making of types with punch, matrix and mold has been widely attributed to Gutenberg. However, recent evidence suggests that Gutenberg's process was somewhat different. If he used the punch and matrix approach, all his letters should have been nearly identical, with some variation due to miscasting and inking. However, the type used in Gutenberg's earliest work shows other variations." -- Wikipedia
