Printing in East Asia evolved from ink rubbings made on paper or cloth from texts on stone tables in China during the Han dynasty (206 BC–220 CE). Mechanical woodblock printing on paper started in China during the Tang dynasty before the 8th century CE. Use of woodblock printing quickly spread to other East Asian countries. While the Chinese used only clay and wood movable type at first, use of metal movable type was pioneered in Korea by the 13th century. The Western-style printing press became known in East Asia by the 16th century but was not fully adopted until centuries later.
Traditionally, there have been two main printing techniques in Asia: woodblock printing (xylography) and moveable type printing. In the woodblock technique, ink is applied to letters carved upon a wooden board, which is then pressed onto paper. With moveable type, the board is assembled using different lettertypes, according to the page being printed. Wooden printing was used in the East from the 8th century onwards, and moveable metal type came into use during the 12th century.
The earliest specimen of woodblock printing on paper, whereby individual sheets of paper were pressed into wooden blocks with the text and illustrations carved into them, was discovered in 1974 in an excavation of Xi'an (then called Chang'an, the capital of Tang China), Shaanxi, China. It is a dharani sutra printed on hemp paper and dated to 650 to 670 AD, during the Tang Dynasty (618-907). Another printed document dating to the early half of the Chinese Tang Dynasty has also been found, the Saddharmapunṇḍarīka sutra or Lotus Sutra printed from 690 to 699.
In Korea, an example of woodblock printing from the eighth century was discovered in 1966. A copy of the Buddhist Dharani Sutra called the Pure Light Dharani Sutra (Hangul: 무구정광대다라니경; Hanja: 無垢淨光大陀羅尼經; RR: Mugu jeonggwang dae darani-gyeong), discovered in Gyeongju, South Korea in a Silla dynasty pagoda that was repaired in 751 AD, was undated but must have been created sometime before the reconstruction of the Shakyamuni Pagoda of Bulguk Temple, Kyongju Province in 751 AD. The document is estimated to have been created no later than 704 AD.
