The additive helps to achieve bright, vibrant screened colours on dyed dark fabrics without laying down an undercoat of white ink. This means that layers of ink do not need to be built up affecting the feel and drape of the fabric.
The Screen Ink Discharge Additive is combined with the screen ink at a rate of 7% by weight to the screen ink. In one action, the Screen Ink Discharge Additive removes the colour from the fabric allowing the screen ink colour to replace it.
Simply screen the image and let it sit for 30 minutes, allowing the ink to dry slightly. Then steam iron at the highest temperature appropriate for fabric for 1-3 minutes (or until image is fully developed). The inks can also be cured/activated immediately after printing in an industrial dryer.
As with all discharge systems, this product will only work on substrates dyed with "dischargeable" dyes and as all colours discharge differently it is recommended to test on fabric prior to use.
