The term ‘ajrak’ derived from the Arabic word ‘azrak’ which can mean ‘indigo’ or ‘blue’. This reflects Sindh’s historic reputation as a dominant producer of indigo dye and illustrates the extensive use of the indigo shade of blue in traditional ajrak print, which is still common to this day.
Ajrakh is printed as single sided and double sided. Traditional 'Ajrakh' involves various stages of dyeing and resist printing using natural dyes and mordants. Indigo and madder are the primary colours that are used for dyeing. The resist and some colours are printed on the cloth using carved wooden blocks. These blocks are carved with intricate symmetrical patterns so that the same block can be used for both sides of the cloth. Earlier specialist wood carvers made these wooden blocks.
