The method of removal of colour from dyed fabric to create white design on coloured background is known as :
Answer: A
The method is discharge printing.
In discharge printing the fabric is first dyed all over, and a chemical discharge paste is then printed on it which destroys (removes) the dye where it is applied, leaving a white design on the coloured ground. A dye that resists the discharging agent can be added to the paste to give a coloured design instead.
In resist printing the design is protected with wax or paste before dyeing, so the colour never reaches it. Duplex printing prints both faces of a fabric, and ikat is a resist-dyeing of the yarns before weaving. None removes colour from already dyed cloth.
