Most of the application tapes in the industry are manufactured to transfer sign vinyl which does not require heat. When using these tapes to apply our products, you may be left with an adhesive residue. In addition, the tape may be difficult to remove which slows down the production process. Our clear mask allows you to accurately place the image on the garment and also releases favorably after heat application. We highly recommend using the TTD High Tack Mask for vinyl and media that is heavier and needs a stronger mask to lift it.
