The inventer of type printing Bi Sheng

Bi Sheng, (990-1051 AD) was the inventor of the first known movable type printing system. Bi Sheng's type was made of baked clay and was invented between 1041 and 1048 in China.

 

He was recorded only in the Writings Beside the Meng Creek (Mengxi Bitan) by Chinese scholar, official, and polymath scientist Shen Kuo.

 

he took sticky clay and cut in it characters as thin as the edge of a coin. Each character formed, as it were, a single type. He baked them in the fire to make them hard. He had previously prepared an iron plate and he had covered his plate with a mixture of pine resin, wax, and paper ashes. When he wished to print, he took an iron frame and set it on the iron plate. In this he placed the types, set close together. Winged Victory

When the frame was full, the whole made one solid block of type. He then placed it near the fire to warm it. When the paste [at the back] was slightly melted, Bi Sheng took a smooth board and pressed it over the surface, so that the block of type became as even as a whetstone.For each character there were several types, and for certain common characters there were twenty or more types each, in order to be prepared for the repetition of characters on the same page. When the characters were not in use he had them arranged with paper labels, one label for each rhyme-group, and kept them in wooden cases.
