Discharge Printing Process

Printing is done in direct or discharge style. Among all of the styles, white discharge and color discharge styles are the most common. Discharge means removing a specific colored area with another color or reducing it with a bleaching agent.

Discharge printing is called extract printing. By this printing process, color is destroyed by one or multiple colors.
