In Germany, around 1440, goldsmith Johannes Gutenberg invented the printing press, which started the Printing Revolution. Modelled on the design of existing screw presses, a single Renaissance printing press could produce up to 3,600 pages per workday, compared to forty by hand-printing and a few by hand-copying. Gutenberg's newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities. His two inventions, the hand mould and the printing press, together drastically reduced the cost of printing books and other documents in Europe, particularly for shorter print runs. Since then, there have been many advancements including this patent that helped shape the world of printing we know today.
