Only later, this process was transferred on paper. The first prints on cloth in China are dated to 220 AD. By the 9th century, the complete printed book appeared in China. After this achievement, printing expanded to Japan and Korea.

But as it can be broken easily, later it was changed to wood and metal type. By 1450, the first modern printing press was introduced in Europe. It was an innovation as it used a matrix. Soon movable type printing spread around the whole world.
