The History of Printing. Movable Type
Text reproduction gets really massive. (11th Century)
Another Chinese invention emerged as a solution to the main flaw of woodblock printing — its static nature. If a carver made even a single error on an entire block, days of labor were tossed into the fire. A simple blacksmith named Bi Sheng found a way to turn printing into a flexible “constructor set” that could be reassembled for different tasks.
The process was elegantly engineered: individual characters were shaped out of sticky clay, fired for durability, and then placed into a metal frame. To keep the type in place, a layer of resin, wax, and ash was applied to the bottom of the frame. After gentle heating, once the mixture softened, the characters were pressed flat with a level board. This created a matrix that, after printing, could be reheated, disassembled, and the letters reused for a new page.
The main obstacle to this idea’s immediate triumph was the Chinese language itself, which required thousands of unique characters for a complete set. Storing and locating the necessary character became a logistical nightmare. Later, in the 13th century, an inventor named Wang Zhen simplified the process: he replaced the fragile clay with wood and designed revolving tables — type cases — for sorting the characters.
Although Bi Sheng’s method did not entirely replace woodblock printing, the principle of movable type was revolutionary. It transformed bookmaking from a meditative craft into a precursor of assembly-line production. This invention predated Gutenberg by nearly four centuries and laid the foundation for the entire future information age.
