Wood block printing technology was introduced in Japan by Buddhist missionaries in around 770 AD. The oldest Japanese book was Buddhist Diamond Sutra printed in 868 AD. By the 11th century, Buddhist temples in Japan were producing Buddhist texts and images using wood block printing. This technology was initially used mainly for Buddhist religious practices.
By the early 15th century, woodblock printing had spread to Europe. Gutenberg improved upon wood block priniting by using types made of metal and ink made of oil.
