Do not upload mirrored images. Apply ready-to-press full-color custom sublimation transfers with a heat press or Cricut Easy Press at low pressure. Irons are not recommended for this ready-to-press custom sublimation transfer. When pressing use a cover sheet such as butcher paper or parchment paper. Use a new sheet of paper for each transfer. Apply these custom sublimation transfers to 100% Polyester garments for a vibrant look. 65% Polyester garments will produce a less vibrant, more vintage look. Sublimation transfers should not be applied to garments that are less than 65% polyester. Sublimation transfers cannot be applied to 100% cotton. Sublimation looks best on white fabric. Other colors may look more faded. Sublimation cannot be seen on dark fabrics. Mousepads, coasters, and mugs must have a polyester coating for proper application of the ready-to-press full-color custom sublimation transfer. The percentage of polyester is the percentage of color that will be applied from the transfer. TURNAROUND TIME: 24 hours excluding holidays/weekends
