High Density HPF, by Insta Graphic System, is a plastisol-based 3D heat transfer that will add considerable texture and loft to your graphic. High Density offers the same raised effect as the traditional screen-printed method—but without the hassle. Heat transfers can be stored and applied on an as-need basis. High Density works best on cotton and cotton blends and its exceptional opacity makes it a great heat transfer for both light and dark colored garments, according to the company.
