Most application masks in the industry are manufactured to transfer sign vinyl – which doesn’t require heat. These types of masking materials aren’t recommended for heat transfer vinyl as they will leave residue on the garment. Additionally, the tape may be difficult to remove which slows down the production process. These CLEAR masks allows you to accurately place the image on the garment, then releases easily after heat application.
Heat Transfer Mask is used to transfer heat transfer graphics to the fabric, such as Siser Easypatterns, Stahls CAD-CUT patterns and StarCraft Transfers for Dark Materials.
Regular HTV such as Siser EasyWeed comes with its own Heat Transfer Mask (also called a carrier sheet) so this is not required for those products. Since the surface has to be exposed on custom printed pattern vinyl for use to print on it, the heat transfer mask is not applied like it is on a product like Siser EasyWeed HTV.
