These badges are printed on a unique “stitch” material. As a result of a unique stitch image generation process, the badges look like they are embroidered. The sublimation process allows the inks to penetrate into the fibre of the polyester twill, embedding them permanently. As a result of the process, the design does not crack or peel later. These are preferred over embroidery or woven badges for images with very intricate details like extensive shading, lots of colours or photographic detail.
