Jul 02, 2018

A printing press is a mechanical device that presses an ink surface against a media surface, such as paper and cloth, for imaging. First invented by the German Gutenberg in 1440. Modern printing machines are generally composed of plate loading, ink painting, press printing, paper transfer (including folding) and other mechanisms. Its working principle is: first, to be printed words and images to make plate, installed on the printer, then by artificial or printing ink coating on the plate there is words and images, and then directly or indirectly, transfer to the paper or other substrates, such as textile, metal, plastic, leather, wood, glass and ceramics), so as to reproduce the same as the plate of the print. The invention and development of the printing press played an important role in the spread of human civilization and culture.
