It is normal for sublimation ink to look dull when it's first printed on the sublimation paper. Once the print is sublimated onto the substrate with the right heat and pressure, the ink converts to a gas and infuses into the material and the colors will become bright and vibrant.
Following to all instructions and not achieving the desired results? There must be additional reasons contributing to this, such as:
The design was transferred using a longer time than necessary, or the temperature and pressure were insufficient. Consult your blank supplier for information on these settings.
Some blanks come with a protective covering. Ensure you remove it before proceeding with the sublimation process.
Moisture plays a significant role in the outcome of your sublimation process, particularly in its interaction with the sublimation coating on various blanks. For instance:
Parchment paper and Teflon sheets are not recommended for sublimation crafting because they are coated and will hold the moisture (won't release it, as it should).
Apply pressure for 12-15 seconds at a temperature range of (143-160°C) for 100% polyester and synthetic materials. Keep the pressure at a medium level of 6 (60 psi). It's essential to recognize that the recommended time, temperature, and pressure settings might vary from one heat press to to another. Please refer to the instructions provided by the supplier.
Here are some tips;
- Using a dehumidifier within your workspace can assist in removing moisture from the air.
- Using heat-resistant tape is beneficial for securing the print, preventing any slight movements that may lead to ghosting, resulting in a shadowy effect.
- Follow the peeling instructions specific to the blanks you are using.
- For optimal / reliable application, use a heat press instead of a heat gun or iron.
