Buyers must distinguish between Inkjet, Laser, and Sublimation transfer papers. For cotton fabrics, Light Transfer Paper is required for white/light garments, while Dark Transfer Paper (which has an opaque white backing) is essential for black or dark textiles. Key metrics include Transfer Rate (ideally >95%), Drying Speed, and Weight (typically 100gsm to 125gsm). Ensure the paper is compatible with your specific ink type, such as Pigment Ink for durability or Sublimation Ink for polyester and hard surfaces.
