LEGO Ideas member PrintNerd used standard LEGO pieces to make models of historical printing presses that really work. On the left is a roller-based press made of 163 pieces. On the right is a lever-operated platen press composed of 312 pieces.
These articulated designs will actually print when used with ink and paper. Like any other printing press, they transfer designs by mashing the design with controlled pressure.
Although other LEGO users use blocks and combinations thereof to engage in printmaking, these projects appear to be rare replications of actual printing machines.
