It's not recommended, since it can quickly damage the poster. If you want to try it, place a cotton sheet or towel over it. Turn the iron to the lowest heat setting. This may remove wrinkles. Another method to try is to mist the poster. Stand back and lightly spray the wrinkled area or spray in the air and pass the poster through the mist. Dry the poster between cotton and under weights. It'll take a day or two for the poster to dry, but it's easier to control the water exposure than it is the heat from the iron.
