how to make sublimation coating for stainless steel

Sublimation coating for stainless steel is a specialized process that allows you to transfer images, designs, or graphics onto the surface of stainless steel items using sublimation printing techniques. This coating is typically applied as a liquid solution and acts as a receptive layer for the sublimation ink. Here’s a general overview of how you can make a sublimation coating for stainless steel:

Materials and Tools Needed:

  1. Stainless Steel Items: These can include stainless steel mugs, tumblers, plates, or other items you want to decorate.
  2. Sublimation Coating Solution: You can purchase a ready-made sublimation coating solution designed for stainless steel or create your own using a clear sublimation coating base.
  3. Spray Gun or Airbrush: To apply the coating evenly and smoothly.
  4. Heat Press Machine: To transfer the sublimation ink onto the coated stainless steel items.


  1. Prepare Your Stainless Steel Items:
    • Ensure that your stainless steel items are clean and free of any dust, dirt, or oil. Clean them with a mild detergent and rinse thoroughly. Dry them completely before proceeding.
  2. Prepare Your Sublimation Coating Solution:
    • If you’re using a ready-made sublimation coating solution, follow the manufacturer’s instructions for dilution and application. If you’re making your own, you can mix a clear sublimation coating base with distilled water in the recommended ratio.
  3. Test Your Coating:
    • Before coating your stainless steel items, it’s a good practice to test the sublimation coating on a small, inconspicuous area to ensure it adheres well and doesn’t cause any adverse reactions.
  4. Apply the Sublimation Coating:
    • Using a spray gun or airbrush, apply an even and thin layer of the sublimation coating solution to the stainless steel item’s surface. Make sure to cover the entire area you want to decorate. Avoid applying the coating too thickly, as this can lead to uneven results.
  5. Allow the Coating to Dry:
    • Allow the coated stainless steel items to air dry completely. This may take a few hours, depending on the environmental conditions. Avoid touching the coated surface during this time.
  6. Sublimation Printing:
    • Once the coating is dry, you can proceed with sublimation printing. Print your desired image or design onto sublimation paper using sublimation ink.
  7. Heat Transfer:
    • Secure the sublimation paper with the printed design onto the coated stainless steel item using heat-resistant tape.
    • Place the item in a heat press machine and follow the manufacturer’s instructions for temperature and duration to transfer the ink from the paper onto the coated surface.
  8. Cool and Finish:
    • After the transfer process is complete, allow the stainless steel item to cool.
    • Once cooled, remove any remaining transfer paper and admire your sublimated design on the stainless steel surface.

Keep in mind that sublimation coating for stainless steel can be a specialized and somewhat complex process. It’s essential to follow manufacturer guidelines and safety precautions when working with sublimation coatings and equipment. Additionally, consider testing the coating process on a sample piece before applying it to your final stainless steel items to ensure the best results.
