Most application masks in the industry are manufactured to transfer sign vinyl (AKA EasyPSV®) – which doesn’t require heat. These types of masking materials are not compatible with heat transfer vinyl as they leave residue on the garment after heat application. Additionally, peeling away the incompatible tape may be difficult and can slow down the production process. So what’s a decorator to do? Turn to Siser of course! We’ve spent a significant amount of time formulating masking materials that work in conjunction with our printable heat transfer materials. TTD High Tack mask is a CLEAR mask that allow you to accurately place the image on the garment and release easily after heat application without any residue left behind. Combining TTD Mask with Siser Print and Cut Materials creates the best application results!
