The generation and evolution of modern printing

China's invention of movable type printing has been further developed and perfected abroad, and has become the mainstream of modern printing. For the ancient Chinese movable type printing, there is a prominent improvement and a major development is the German Gutenberg, he created the lead alloy type type printing, widely used by countries all over the world, until now, is still one of the contemporary printing methods.

Gutenberg created movable type printing in the period from about 1440 to 1448 AD. Although the type of invention was later than 400 years old, Gutenberg improved the type of movable type materials, used fat inks, and manufactured the printing presses. Both have achieved great success and laid the foundation for modern printing. Scholars from all countries recognize that the founder of modern printing is Gutenberg in Germany.

The material used by Gutenberg as a movable type is lead, tin, and tantalum alloys, which are easy to mold and have good movable type printing performance. The proportioning components like this have not changed much even after 500 years. In the process of casting, Gutenberg uses a word box and a font for casting, which makes it easy to control the size of the movable type and facilitates mass production. Gutenberg also pioneered the use of fatty inks, greatly improving the quality of printing, and fatty inks have been used up to now. Although Gutenberg's invention of a printer was simple, it improved the operation of printing and was a copy of the printing press. These are all the technical reasons that Bi Sheng's invention of movable type printing does not have, and that Bi Sheng type printing cannot be widely circulated. The creation of Gutenberg has made a leap forward in printing technology.

Gu Dengbao's first type of movable type printing was first spread from Germany to Italy, then to France, and when it reached the United Kingdom in 1477, it had spread all over Europe. A century later it spread to Asian countries. It was spread to Japan in 1589 and the following year it was spread to China. Gutenberg’s method of casting, typesetting, and printing, as well as his first spiral-type handprinter, have been used in countries all over the world for more than 400 years. During this period, the scale of the printing industry was not large, and the printing factories were mostly of the nature of handicrafts.

In 1845, Germany produced the first rapid printing press, after which the mechanization process of printing technology began.

In 1860, the United States produced the first batch of rotary machines. After that, Germany successively produced two-color fast printing presses and rotary printing presses for printing newspapers. By 1900, six-color rotary printing machines were manufactured. From 1845 onwards, after about a century, industrialized countries have successively completed the mechanization of the printing industry.

Since the 1950s, printing technology has continuously adopted the achievements of emerging science and technology such as electronic technology, laser technology, information science, and polymer chemistry, and it has entered a stage of modernization. In the 1970s, the popularity of photosensitive resins and PS plates made printing into a multi-color high-speed way. In the 1980s, the application of electronic color separation scanners and full-page imposition systems enabled the copying of color images to be digitized and standardized, while the continuous improvement of the technology of Chinese-character information processing for sleeping lasers caused a fundamental change in the text-based typesetting technology. . In the 1990s, the introduction of the color desktop publishing system showed that the computer entered the printing field. In short, with the rapid development of modern science and technology, printing technology has changed rapidly.
