The ideal pressing recipe for most T-shirts for sublimation is 385 degrees F for 30 seconds with a medium pressure. We have found these settings to produce the most vibrant, consistent prints.
With that said, it is always important to note any manufacturer-recommended times and temperatures as not all shirts are the same. You can also experiment with adjusting your time and temperature settings if you are not getting the results you would like.
