Troubleshooting Dull or Faded Sublimation Colours

Designs may look dull on sublimation paper, but when heat and pressure are applied, the ink turns into a gas and infuses into the material, producing vibrant colours.

If the colours look dull on the blank after sublimating, it could be due to:

• Incorrect time, temperature or pressure: Too much or too little heat, transfer time or pressure can affect the colour. Check the recommended settings with your blank supplier.

• Protective film: Some blanks have a very thin and almost invisible protective film. Make sure it is removed before sublimating.

• Excess moisture: Moisture in the blank can cause ghosting, uneven transfers or dull colours. Store blanks in a dry place and remove excess moisture before applying your design. You can use a heat press on low heat for a short time to help dry the blank before sublimation.

• Note:

Parchment paper and Teflon sheets are not recommended for sublimation crafting because their coatings can trap moisture rather than release it. In contrast, butcher paper is preferred as it absorbs moisture effectively, ensuring even heat and pressure distribution. This leads to a more consistent transfer of the design onto the substrate.

Here are some tips;

• Heat-resistant tape is useful for securing prints, preventing slight movements that could cause ghosting or a shadowy effect.

• Always follow the peeling instructions specific to the blanks you're using.

• For the best results, use a heat press instead of a heat gun or iron to ensure reliable application.
