PU heat transfer vinyl gets its color from using colored pigments. Pigments are added to the PU material during the manufacturing process to give the vinyl a specific color. PU heat transfer vinyl is a type of vinyl that can be cut into shapes and designs and then applied to fabric using a heat press.

The pigments used in PU heat transfer vinyl are usually organic or inorganic compounds that are finely ground and dispersed throughout the vinyl. Organic pigments are made from natural substances such as plants and minerals, while inorganic pigments are made from synthetic materials such as metal oxides.

The choice of pigments used in PU heat transfer vinyl is critical to achieving accurate and consistent color. Manufacturers carefully select heat-stable and non-fading pigments to ensure that the vinyl retains its color intensity and vibrancy even after repeated washing or exposure to sunlight.
