From 1845 onwards, about a century, the industrial developed countries have completed the printing industry of mechanization.
From the beginning of the 50's in twentieth Century, printing technology continues to use the electronic technology, laser technology, information science and polymer chemistry and other new scientific and technological achievements, entered the stage of the development of modernization. In 70, the popularity of photosensitive resin relief, PS version of the way, the printing entered the development direction of the high-speed multi-color. In the 1980s, electronic color scanner and full page make-up system application, the color image reproduced to achieve the data, standardization, and Chinese character information processing sleep laser photo typesetting technology continue to improve, to produce a fundamental change in the text typesetting. 90 time, the introduction of the color desktop publishing system, which shows that the computer has entered the printing field.
