Japan is the first country to develop printing technology after China. In the 8th century, Japan could print Buddhist scriptures by block printing.
North Korea's woodblock printing technology was also introduced from China, and began to print Confucian classics in Mu Zong (998~ 1009).
After Bi Sheng invented movable type printing, Koreans began to print books with clay type, and later printed books with wood type.
/kloc-In the 3rd century, they first invented printing books with copper movable type.
China used copper movable type printing later than North Korea.
Koreans also created lead movable type and iron movable type.
The person who uses mimeograph technology to print documents in the west is geist Tanner, a Hungarian living in Britain.
About 188 1 years ago, he used wax paper fiber paper as a template and engraved the information to be printed on it with an iron pen, and micropores appeared on the fiber engraved with the iron pen. Then he brushed the ink on the plate and pressed it with a roller to make the ink pass through the wax plate and adhere to the paper below.
Inventor Edison also studied stencil printing in the early 20th century. He matched the iron pen with the motor, and controlled the motor to make the iron pen engrave words on the paper to make mimeographs.
Although this method was not widely valued and put into practice at that time, its principle inspired future generations.
1888, geist tanner replaced the stylus with a typewriter. He removed the ribbon from the typewriter and let the words directly hit the wax paper, leaving traces on the wax paper.
The waxed paper was removed, spread on paper, inked and stamped, and it was successful.
10 years later, the Austrian Clabau invented the rotary mimeograph, which greatly improved the speed of mimeograph.
Gravure printing-Gravure printing was produced in the middle of15th century. The principle is to make the graphics and text of the printing plate lower than the blank part, and the layout structure is similar to that of China ancient rubbings, but the inked part is just the opposite of the rubbings.
Because the ink on the surface of the finished product printed by this printing method is slightly raised, it is easy to distinguish and difficult to imitate, so it is mostly used to print valuable securities such as banknotes and stamps.
Gravure printing plates can be divided into engraved intaglio, etched intaglio and photogravure.
Gravure printing of carved copper was invented by Italian Fina Qiu Lai. 1477, the map was printed in this way.
At the beginning of19th century, Europe began to copy famous paintings and print valuable securities by this method, and gradually developed gravure printing into a unique printing method.
