 It has also been suggested that the method used by Gutenberg involved using a single punch to make a mould, but the mould was such that the process of taking the type out disturbed the casting, causing variants and anomalies, and that the punch-matrix system came into use possibly around the 1470s.This raises the possibility that the development of movable type in the West may have been progressive rather than a single innovation.Gutenberg's movable-type printing system spread rapidly across Europe, from the single Mainz printing press in 1457 to 110 presses by 1480 – 50 of them in Italy.
