Four processes of printing

The first step is to make an inverted letter model of single words in Yang Wen; the second step is to select single words according to the original manuscript and arrange them in a font plate; the third step is to daub ink for printing; and the fourth step is to remove fonts after printing, so that they can be used again in the next typesetting.

Movable type printing is an ancient printing method, which was invented by working people in ancient China through long-term practice and research. The invention of movable type printing is a great technological revolution in the history of printing. The clay movable type invented by Bi (970- 105 1) during the Northern Song Dynasty and the Qing Dynasty in China marked the birth of movable type printing.

He was the first inventor in the world, about 400 years before Johannes Gutenberg invented movable type printing. In Yuan Dynasty, Wang Zhen successfully created wooden movable type and invented wheel typesetting. In the middle of Ming Dynasty, copper movable type was widely used in Nanjing, Wuxi, Suzhou and other places in Jiangsu.
