Sublimation Dye Application Instructions – Heat Press Guide

1. Prepare Your Substrate

• Use polyester fabric (65%+ polyester) or sublimation-coated blanks for the best color transfer.
• Pre-press garments for 5–10 seconds to remove moisture and wrinkles.
• Clean mugs, tumblers, or other hard blanks of lint, dust, or oil for a smooth print surface.
  
• Always ensure your blanks are rated for sublimation printing.

2. Align and Tape

• Place your sublimation transfer sheet face down on the blank.
• Use heat-resistant tape to hold the transfer firmly in place.
• Prevent ghosting by keeping the transfer from shifting during the press.
• Cover with butcher paper or a Teflon sheet to protect your heat press from ink transfer.

3. Heat Press Settings for Sublimation

• Set your heat press between 385–400 °F (195–205 °C).
• Apply medium to firm pressure for consistent ink transfer.
• Press for 45–60 seconds for shirts, or 180–200 seconds for mugs and tumblers.
• Check your substrate manufacturer’s guidelines for ideal settings.

4. Transfer & Cooling

• Once pressing is complete, remove the paper carefully while it’s still warm.
• Allow the product to cool fully before touching or packaging.
• Inspect the design to ensure sharp lines and even color saturation.

5. Pro Tips for Perfect Sublimation

• Always test a sample press before production.
• Use a lint roller on fabrics to avoid stray fibers in prints.
• Avoid cotton materials — sublimation only bonds with polyester or coated surfaces.
• Store your transfers in a cool, dry place to prevent fading before use.

6. Recommended Sublimation Settings

• Polyester Shirt: 400 °F, 60 seconds, medium-firm pressure
• Coated Mug or Tumbler: 380–400 °F, 180–200 seconds, medium pressure
• Aluminum or Hardboard: 385 °F, 60 seconds, medium pressure
