Discharge Printing: Discharge ink is a water-based product that deactivates the dyes used on natural fabrics. You have probably seen many shirts with a very soft print that looks like the Colour of natural cotton - this is discharge printing. Discharge screen printing can be used to print Colours on dark garments that in the past would have required an additional layer of white ink in order to achieve proper opacity of top colors. Slight variation in Colour is possible in an actual product due to lights used in photography or your screen resolution. Best way to look cool and comfortable.
