Due to limited shelf life of pre-mixed ink Dye Discharge is supplied in components. The DC 294 Discharge Agent the active component of our Dye Discharge System. When mixed with one of our Dye Discharge Bases, the DC 294 destroys the original fabric dye to replace it with the color of the ink being printed. The process must involve a heat cure. When the printed ink reaches its cure temperature, the discharge agent begins to knock out the original dye. This process works best on 100% cotton that has been dyed using dischargeable fiber reactive dyes. Other reactive and sulphur dyes may work HOWEVER, always test first to be sure.

Dye Discharge may be used as a ‘first down’ on dark shirts and then overprinted with plastisol. This will create garments with a ‘soft hand’ feel with the ease of plastisol printing for the balance of the colors. Dye Discharge may be run first then flashed until discharge takes effect and then printed wet on wet with plastisol. In many cases the Dye Discharge Ink can be printed and then over printed immediately with plastisol. In these cases the discharge effect will take place in the dryer, providing the dryer has a long enough tunnel and adequate heat and hot air movement. Always test first to make sure the shirts are properly discharging before beginning production run. The DC 2015 White or DC 2018 High Opacity White can make an ideal ‘first down’ choice. DC 2012 Base can be used with Colour Tones Pigments to make colours or it can be used as a ‘first down’ where a white underbase is not required.

Technical Details:

Mixing Instructions: The following guide is somewhat flexible and may be altered to suit your specific requirements. Example:

DC 2012 Discharge Base (less container)………………………………..….…100g

DC 294 Formaldehyde Free Discharge Agent – 5% base weight……….…….5g

WA 392 Wetting Agent – 10% of base weight…………….………………………10g

Colour Tones Pigment – 5-20% of base weight………………….………….…5-20g

Retarder or Thickener………………………………………………..………as required

Stencil: We recommend using a DZ-343 by Image Mate.
Mesh: Dye Discharge should be printed thru 60 to 120/inch (24T to 48T/cm)
Additives and Reducer: If ink is drying too quickly in the screen add up to 10% AQT 2594 Retarder. If ink viscosity is too thin it may be thickened by adding ½ – 1% TH 100 Thickener. Mix well and let sit for 10 minutes. If ink needs to be reduced, small amounts of distilled water may be added.
Squeegee: Use a soft (60) to medium (70) durometer.
Curing: 300-350F (150- 160C) for 2-3 minutes. Cure prints immediately after printing. Water is necessary to begin the discharge process so DO NOT let prints air dry first before curing. For shops not equipped with hot air dryers cure with a heat transfer machine. Set machine to 350F (177C) and cure for 25 seconds. Tests for product compatibility should always be conducted prior to production runs.
