Multimedia applications use text to explain concepts, messages and provide impact. Moveable type made of clay and wood was invented in China during the ninth century.

He created metal alloys suitable for making type, processes for the manufacture of ink and implemented bookmaking techniques. It took him two years to set the type for his bible and another two years to print a total of 210 copies.
