The ink used in mimeograph technology is mainly an ink that can be copied quickly. It is a mixture, mainly composed of pigments, additives and gums. The smooth development of mimeograph technology mainly depends on the color, drying performance and fluidity of ink. As long as these three properties are excellent enough, it can successfully develop mimeograph technology. The mimeographed technology in China was invented in 500 AD, when people could already print books with this mimeographed technology.
Although the mimeograph technology in the past is not mature, it can make the office copy faster and more efficient, that is to say, people can use this technology to print out the required items quickly. Although this technology can't get enough attention at that time, it can't be denied that its contribution is great. After China successfully developed mimeograph technology, Hungarians also invented a similar technology of rolling printing with oil drums, and later he invented a typewriter.
After a long time, it was not until the 20th century that mimeographed technology was gradually replaced, and it had a very extensive use history in ancient China. Some people say that Edison invented it first, and then it spread to Japan. In fact, it was China who invented it first, then it spread to Japan and then to the United States. Mimeograph technology is a printing technology formed by comprehensive means such as typesetting, plate making and printing.
