Where does block printing come from?

Even before Europeans mastered the art of printing using a press, the Chinese introduced a form of printing that used hand-carved wooden blocks. This technique used paper and ink (both of which originated in China itself). This technique was inspired by the idea of using carved seals (originally from Mesopotamia). Slowly and gradually, the same was popularly referred to other parts of Asia, and hence the art of block printing on fabric gained popularity. India, too uses the technique to get the famous Bagru prints on the fabric that uses block prints and locally sourced dyes. This technique is extremely simple and sustainable. These blocks can be used for a long time and are affordable.
