The Story:
In the mid-15th century Johannes Gutenberg invented a mechanical way of making books. This was the first example of mass book production. Before the invention of printing, multiple copies of a manuscript had to be made by hand, a laborious task that could take many years. Later books were produced by and for the Church using the process of wood engraving. This required the craftsman to cut away the background, leaving the area to be printed raised. This process applied to both text and illustrations and was extremely time-consuming. When a page was complete, often comprising a number of blocks joined together, it would be inked and a sheet of paper was then pressed over it for an imprint. The susceptibility of wood to the elements gave such blocks a limited lifespan .
In the Far East, movable type and printing presses were known but did not replace printing from individually carved wooden blocks, from movable clay type, processes much more efficient than hand copying. The use of movable type in printing was invented in 1041 AD by Bi Sheng in China. Since there are thousands of Chinese characters, the benefit of the technique is not as obvious as in European languages.
In China, there were no texts similar to the Bible which could guarantee a printer return on the high capital investment of a printing press, and so the primary form of printing was wood block printing which was more suited for short runs of texts for which the return was uncertain
It is not clear whether Gutenberg knew of these existing techniques or invented them independently, though the former is considered unlikely because of the substantial differences in technique.Europeans use xylography (art of engraving on wood, block printing) to produce books and used by European textile makers to print patterns on fabric.
