How to Take Crease Marks Out of Posters

Use an iron to help get rid of poster creases.

If you are dealing with poster creases, there are a few different methods you can try to renew the look of your poster.

Weight Method

1. Lay the poster out on a flat surface, such as a dining room table or coffee table. Place a sheet of wood, glass, or anything else with a smooth flat surface that will cover the creased areas of the poster.

2. Place a heavy weighted object such as books, weights, or other weighted objects over the top of the material covering the poster.

3. Allow the weights to site on the poster for at least 24 hours. Check every 24 hours to see if any progress is being made on the creases.

Iron Method

1. Place the poster on a clean ironing board. Cover the poster with a tea towel or other lightweight towel to prevent scorching while ironing.

2. Turn your iron to it's lowest setting. Turn the steam off so that you do not accidentally water damage your poster beneath the cloth.

3. Slowly move the iron across the towel covering being careful not to leave the iron in one place for more than about five seconds at first. If the creases still remain, increase the amount of time with the iron over the creased area to 10 seconds. If the creases still remain, slowly increase the heat of iron, being sure to regularly look at the poster beneath to ensure that no heat damage is being done.

Tip

If your poster is an antique or valuable or if you are unsuccessful with the above methods, contact your local framing store and ask if they have a heat press that can be used to uncrease your poster.
