Woodblock printing on textiles is the process of printing patterns on textiles, usually of linen, cotton or silk, by means of incised wooden blocks. It is the earliest, simplest and slowest of all methods of textile printing. Block printing by hand is a slow process.
The wood block is carefully prepared as a relief pattern, which means the areas to show 'white' are cut away with a knife, chisel, or sandpaper leaving the characters or image to show in 'black' at the original surface level. The block was cut along the grain of the wood. It is necessary only to ink the block and bring it into firm and even contact with the paper or cloth to achieve an acceptable print. The content would of course print "in reverse" or mirror-image, a further complication when text was involved.
