Heat Press at 270 Degrees Fahrenheit for 12-30 Seconds

To properly iron on the patch temperature is important and must be 
between 260-280 Degrees Fahrenheit. 30 Seconds of applied pressure
 at the correct temperature is needed using a household iron. 
12 Seconds is enough if using a heat press.

Plug in iron. Crank it to highest setting. Place iron on top of your 
garment with a frying pan thermometer sandwiched between iron 
and garment to start the preheating process. Once temperature 
reaches 280 Degrees Fahrenheit unplug your iron. Temperature will
 continue to rise and then start to decline. Once it declines to 280 
Degrees Fahrenheit, Slide the iron, place your patch and put the iron
 on top of your patch and press as hard as you can for 30 seconds 
without moving the iron around. Do not mess with the patch until it 
has completely cooled down. Do not iron on patches to Leather or 
Nylon!
