Avoiding Film Marks
Undesired film marks on sensitive fabrics can be avoided by cutting the transparent film close to the edge of the motif. Apply the product for a short time, using a small amount of pressure. Then remove the transparent film and press again following the recommended time and pressure settings.
If the film has already left marks, the surface structure of the carrier material can usually be restored by brushing, using a steam iron or by re-pressing it in the heat press.
