Laser Photocopying System Makes News and Publications Older

The laser photocopying system is a 748 institute of Peking University, developed by Chinese science represented by Prof. Wang Xuan. It caused us to bid farewell to lead and fire and set off a revolution in the field of Chinese character information processing. It is yet another major innovation since Bi Sheng invented movable type printing technology.

Once upon a time, printing was a very hard job. Workers in the hill-like lead stack, swearing, typing, proofing, making paper, and printing on the printing press. When encountering unusual characters, it is also necessary to cast the characters at high temperatures, which is very hard and lead poisoning. Moreover, type printing is very inefficient.

Researchers led by Professor Wang Xuan, after more than a dozen years of research, have finally launched the Peking University Founder laser photocopying system, which includes book editions, newspaper editions, and other parts, so that the publishing and printing industry bid farewell to lead and fire. Moreover, they also introduced the Founder Color Publishing System, which has made the news publishing industry “change its appearance”.

The so-called laser photocopying process is to use a computer to enter text and use a certain format for typesetting (in the case of a book, after two scans to form a S2 scan file); printing this format file with a printer can make it The contents appear on the paper; if you use the laser imagesetter to issue the output, and after washing, you can get a film for printing (equivalent to paper type). This film was taken to the printing factory, after printing, imposition, printing and other processes, preservation and other characteristics, therefore, it basically replaced the type of printing.
