What temperature to use may vary depending on the fabric you are using, as well as the type of transfer film.

Natural fibres and materials such as cotton will be able to withstand firm pressure with temperatures of 320˚F or 160˚C.  However, you will need to be careful with polyester, as it is at greater risk of getting damaged at higher heats.

Heat transfer vinyl should be applied to polyester at heats no hotter than 270˚F or 130˚C.  While the fabric does have a higher boiling point, this is the optimum temperature to use for the best results.

As a general rule, we recommend testing press any designs you print to ensure you find the best rhythm and process for the results you desire.
