Condé LaserMPrints™ OPAQUE for Cotton Heat Transfer Paper, Pack -50 sheets. LaserMPrints OPAQUE for Cotton Heat Transfer Paper is a single-sheet opaque material designed for both oil and oil-less color laser copiers and color laser printers for the transfer of high-resolution photographs and full-bleed images to dark cotton garments. Recommended for 100% cotton to 50/50 blend fabrics only. DO NOT use with synthetic fabric material. Make sure to test any blend material for “dye migration” by applying a blank piece to material and heating for recommended temperature. If test material discolors, then use a different fabric material or use LaserMPrints OPAQUE for Polyester instead. LaserMPrints OPAQUE for Cotton can be used with a plot or vinyl cutter to remove excess film. Use a “low tack” application film to remove cut pieces from the backing sheet. LaserMPrints OPAQUE for Cotton should be applied with a commercial heat press. DO NOT overheat material within heat press, as this may result in wash durability issues. Must use with Silicone protective sheets when applying material to fabric. Silicone Matte Finishing Sheets included. Gloss Finishing Sheets (GFP-1116XXV), sold separately. Allow 24 hours for design to “cure” on fabric material before washing and drying.
