how to keep sublimation from fading

Sublimation is a printing process commonly used for textiles, mugs, and other products where vibrant and long-lasting colors are desired. While sublimation printing is known for its durability, there are still some factors that can contribute to fading over time. To help keep sublimation prints from fading, follow these tips:

  1. Choose Quality Sublimation Materials:
    • Start with high-quality sublimation inks and substrates (the materials being printed on). Quality materials are less likely to fade quickly.
  2. Use Quality Printing Equipment:
    • Invest in good sublimation printing equipment, including a high-resolution printer and a reliable heat press. Quality equipment can result in better color retention.
  3. Select Substrates with a Polyester Coating:
    • Sublimation works best on materials with a polyester coating or a high polyester content. These materials are more receptive to sublimation inks and tend to hold the colors better.
  4. Pre-Treat Substrates Properly:
    • Some substrates may require pre-treatment with a special coating or spray to enhance sublimation ink adhesion. Follow manufacturer recommendations for pre-treatment.
  5. Ensure Proper Heat and Pressure:
    • Use the correct temperature and pressure settings on your heat press when transferring the design onto the substrate. Inadequate heat or pressure can result in incomplete sublimation and fading.
  6. Use the Right Time and Temperature:
    • Follow the sublimation transfer time and temperature guidelines provided by the manufacturer of the inks and substrates. Proper time and temperature are crucial for color vibrancy.
  7. Avoid Overheating:
    • Overheating the substrate can cause fading or color distortion. Be careful not to exceed the recommended temperature and pressing time.
  8. Prevent Heat Press Ghosting:
    • Ghosting occurs when a printed image partially transfers onto the protective paper and then back onto the substrate. To prevent this, use high-quality, anti-ghosting sublimation paper.
  9. Wash and Care Instructions:
    • Provide care instructions to the end-users of sublimated products. Washing and caring for sublimated items according to these instructions can prolong the vibrancy of the colors.
  10. Avoid Bleach and Harsh Detergents:
    • Instruct customers to avoid using bleach or harsh detergents when washing sublimated textiles, as these can weaken the colors.
  11. Wash Inside Out:
    • Encourage customers to wash sublimated clothing items inside out to minimize friction and reduce color abrasion during washing.
  12. Limit Sun Exposure:
    • Sunlight and UV rays can fade sublimation prints over time. Advise customers to store and use sublimated items away from direct sunlight when possible.
  13. Test Prints and Processes:
    • Before producing a large batch of sublimated products, perform test prints and processes to fine-tune settings and ensure the best color retention.
  14. Monitor Dye Migration:
    • Dye migration can occur when sublimation inks bleed into the fabric or substrate. To prevent this, use a blocking paper or barrier sheet when pressing.

By following these tips and best practices, you can help ensure that sublimation prints maintain their vibrancy and resist fading for a longer period, resulting in more durable and long-lasting products.
