How can I stop unexposed areas of my print from continuing to develop?

Slight tinting of the fabric can occur, especially with some of the darker Inkodye colors. The basic issue is that the fabric "holds on" to small amounts of residual dye, which continue to develop later on. 

If you are looking to print logos, we recommend using the new tools at lumi.com, see our FAQ about printing logos. To minimize background tinting, these tips may improve your results:

  • For best results we recommend washing your print twice with Inkowash right after it is done exposing. Use the hot wash and cold rinse cycle if possible.
  • Ensure that your negative is opaque enough to fully block the light areas of your print. Learn more about making darker negatives.
  • Before washing, quickly rinse your fabric in a sink to remove as much of the liquid dye still sitting on the surface. This ensures there isn't as much dye floating in the wash.
  • Depending on where you live, the quality of your water can have a major effect on the washing process. Minerals in hard water can inhibit detergents. To solve this issue you can use a chemical water softener such as borax. Depending on how much fabric you are washing you may consider washing with distilled water.
  • Consider pre-washing your fabric with Inkowash. This will help remove dirt and other impurities that can make it harder for unexposed Inkodye molecules to break free after printing.
  • Certain fabrics, especially thicker ones tend to "hold" the dye more than others, consider trying different materials.

CAUTION: Do not use bleach to clean Inkodye. Inkodye is resistant to bleach and contains ammonia that can react with bleach to create toxic fumes. Learn more about Inkodye safety.
