We conduct wash testing on Cricut heat-transfer materials with Cricut heat presses to establish their longevity. You can find settings for these materials in the Cricut Heat Guide at cricut.com/heatguide.
Testing is also conducted for non-Cricut heat-transfer materials, but due to the large variety of materials and different formulas on the market, Cricut is unable to give exact settings.
When working with custom heat transfers (such as screen print or plastisol and direct to film/DTF prints), keep in mind that Cricut Autopress works differently than traditional heat press products. Cricut Autopress automatically applies consistent pressure for projects up to 2 in thick. This makes transfers easy and repeatable. This also means that if you're using custom heat transfers, the settings for Cricut Autopress will differ from those recommended by the manufacturer. Cricut has tested a wide variety of these materials with Cricut Autopress to achieve beautiful and consistent results. When working with non-Cricut manufacturer settings, we recommend increasing the temperature by approximately 20% and increasing the length of the pressing time to roughly 30 – 60 seconds. Custom transfer materials can also vary, so use the settings that work best for you.
