It's easy.Block printed fabric is produced in India, this cotton is thinner that that used in the fabrics from China and is traditionally produced by printing the designs from wooden carved blocks. Ajrakh fabric is produced by dipping the wooden blocks in dye and then printing on the fabric - often multiple times in different colours and with different blocks. Mud print adopts the same principle but the wooden blocks are dipped in a mud solution which is dried before dyeing. The mud acts as a barrier in a batik type of way. Many of the fabrics have mutitple hues, indicating the reprinting and re-dyeing process happens many times.
