In addition, is a method for dyeing textiles (usually silk) using wood blocks invented in the 5th-6th centuries in China. An upper and a lower block is made, with carved out compartments opening to the back, fitted with plugs. The cloth, usually folded a number of times, is inserted and clamped between the two blocks. By unplugging the different compartments and filling them with dyes of different colours, a multi-coloured pattern can be printed over quite a large area of folded cloth. The method is not strictly printing however, as the pattern is not caused by pressure against the block.
Colour is very common in Asian woodblock printing on paper; in the first known example is a Diamond sutra of 1341, printed in black and red at the Zifu Temple in modern-day Hubei province. The earliest dated book printed in more than 2 colours is (: ), a book on ink-cakes printed in 1606 and the technique reached its height in books on art published in the first half of the 17th century. Notable examples are the 's of 1633, and the published in 1679 and 1701.
The earliest woodblock printed fragments to survive are from China and are of silk printed with flowers in three colours from the (before AD 220). It is clear that woodblock printing developed in Asia several centuries before Europe. The Chinese were the first to use the process to print solid text, and equally that, much later, in Europe the printing of images on cloth developed into the printing of images on paper (). It is also now established that the use in Europe of the same process to print substantial amounts of text together with images in block-books only came after the development of , which was developed by (990–1051) during the of China, about four hundred years later.
For colour printing, multiple blocks are used, each for one colour, although overprinting two colours may produce further colours on the print. Multiple colours can be printed by keying the paper to a frame around the woodblocks.
