How does printing work?

Before the birth of printing, people published a work entirely by hand copying, with no guarantee of quality. With the introduction of ink and paper, engraving was born. It operates by carving a text onto a wooden plate with a backhand. When printing, ink is brushed on the plate, and then the paper is covered on the plate and gently brushed solidly with a clean brush, and black writing appears on the paper.

Early in the 20th century, archaeologists discovered the "Diamond Sutra" carved and printed in the ninth year of the Tang Dynasty in the Thousand Buddha Cave in Dunhuang, Gansu Province, which became the earliest printed object in the world marked with the exact date of carving and printing.

Bi Sheng, the inventor of movable-type printing, has been through more than 1,000 years of trials and tribulations since the rise of engraving. After a long period of exploration, movable type printing was born. Its introduction not only recorded and spread the traditional Chinese culture and civilization, but also led to the development of culture, art and science around the world, and all this is attributed to the originator of modern printing - Bisheng.
