Printing with Waterbase Discharge inks...

Waterbase Discharge
Discharge Inks, like all water-based systems are designed to penetrate the garment. The print in essence becomes part of the garment, eliminating such problems as heavy hand and fibrillation. In addition, you can dry clean or iron the garment without distorting or damaging the image. Designs printed with Plastisol would melt and distort with the heat or break down and lose adhesion. Most importantly, Waterbase Discharge Inks give you the ability to print dark garments without the use of an under-base white. The best result is a print with a softer hand.
The garment is the most important factor, since not all garments are dischargeable. The fabric must be 100% COTTON. Second, the garment must be dyed with dischargeable dyes and the results can differ from dye lot to dye lot. Polyester or Poly Blends will not discharge. The color of the garment can affect the results and some Colors discharge better than others. That is why is recommended to always test before you start production.

Here are some additional things you'll need when working with Waterbase and Discharge products:
- Water Resistant Emulsion, such as: Textil DW or Graphic HU
- Stencil Hardener, such as Fixer 9
- Conveyor Dryer with a Recirculating Blower
Recommended Substrates: 100% Cotton fabrics
(Treated with dischargeable dyes) NOT RECOMMENDED for Polyester or Poly blends Mesh: 86-110 t/in (34-43 t/cm) for better discharge. Mesh: 110-195 t/in (43-77 t/cm) for finer lines. Flash Temp: N/A Curing Temp: 300°F for 2-3 min. (Waterbase inks require longer exposure to heat to completely evaporate the water content, a dryer with a recirculation blower would be more efficient) Stencil: Water-Resistant Emulsion Stencil Hardener is recommended when emulsions are not sufficiently resistant to Discharge inks. Storage: Unlike Plastisol inks, Waterbase inks require a properly closed lid when they’re not in use; this will prevent the ink from air-drying. |
Additives/Modifiers: Low Crock can be added to improve wash fastness.
Drying: 300 to 320 degrees F for 2.5 - 3 minutes
FINISHING: It is highly recommended to wash and dry garments or fabrics before packaging and shipping.
Wash up: Use water and mild soap to wipe screens, screen frames and squeegees and any surfaces in contact with ink.

Discharge 1-Part (no powder required)

The smell of the conventional Discharge inks have always been an issue for users, with the introduction of the 1-Part Discharge Base customers can now eliminate the use of a Formaldehyde-based product. This product does not require activation with Discharge Powder and it exhibits a pleasant smell. Storage requirements: Keep product closed in a airtight container while not being used. Use 1-Part Discharge Base directly on 100% cotton to remove the dye color of the fabric or add waterbase pigments to achieve a desired color tone. Addition level of Pigment Concentrates is the same as any other waterbase product. Refer to the Printing Parameters for the proper use of this product.
Recommended Substrates: Cotton 100% (Treated with dischargeable dyes)
NOT RECOMMENDED for Polyester or Poly blends
Mesh: 86-110 t/in (34-43 t/cm) for best results and 110-195 t/in (43-77 t/cm) for finer lines.
Curing Temp: 300°F for 2-3 min.

Stencil: Water-Resistant Emulsion
Stencil Hardener is recommended when emulsions are not sufficiently resistant to Discharge inks.
