Sublimation printing has revolutionized the world of design and customization, offering vibrant, durable, and visually stunning prints. Whether it’s apparel, home decor, or promotional materials, sublimation prints are a popular choice for those seeking lasting and captivating visuals.
At its core, sublimation printing is a process where heat and pressure turn special inks into gas, permanently bonding them to polyester fibers. Because the ink becomes part of the material, maintaining its brilliance depends on both printing technique and long-term care. In this guide, we’ll explain the science behind fading and show you how to prevent it step-by-step from materials to washing habits.
Quick Recap
To prevent sublimation fading, use 100% polyester or high-poly blends, apply correct heat (380–400°F) and pressure, and use premium inks and transfer paper. Wash items in cold water, avoid fabric softeners, and dry naturally. Protect prints from UV light and moisture for maximum longevity.
Why Sublimation Prints Fade: Common Causes and Solutions
Before we explore the main reasons sublimation prints fade, it helps to understand what happens beneath the surface. During printing, sublimation dye turns into gas under heat and bonds with polyester fibers at a molecular level. When that bond weakens, often because of incorrect heat, pressure, or UV exposure, the colors begin to lose their vibrancy.
While sublimation printing offers remarkable color vibrancy and durability, it’s essential to be aware of the potential factors that can lead to fading over time. Understanding these factors empowers you to take proactive measures to preserve the brilliance of your prints.
Let’s explore some common reasons for fading sublimation prints and discover effective solutions to counteract these challenges.
Incorrect Heat or Pressure
One of the leading causes of fading in sublimation prints is incorrect heat application and pressure during the transfer process. Inadequate heat and pressure can result in incomplete ink transfer. This means the ink hasn’t properly turned into a gas and can’t embed itself into the fabric adequately, leading to faded or dull colors.
To combat this, follow the manufacturer’s guidelines for temperature and pressure settings. Regularly calibrating your heat press machine and conducting test prints can help achieve optimal results, which also depends on the fabric being sublimated.
Low-Quality Transfer Paper
Using substandard transfer paper can significantly affect the longevity of sublimation prints. Inferior transfer paper may not hold the ink properly, leading to premature fading. Invest in high-quality transfer paper that is specifically designed for sublimation printing.
Quality paper ensures better ink absorption, resulting in vibrant and long-lasting prints. It’s always a good idea to test out various papers on test fabrics to see which appears to yield the best results!
Poor-Grade Inks
The ink quality used plays a crucial role in how well sublimation prints retain their vibrancy over time. Inferior inks may fade more quickly due to their chemical composition. Opt for well-regarded, fade-resistant sublimation inks from reputable manufacturers. Though they might be pricier, they can significantly extend the life of your prints and maintain their original vibrancy.
Color Management Issue (technically not fading)
Even with premium inks and perfect heat settings, you might still notice your prints looking dull or inconsistent across batches. In many cases, this isn’t a fading issue — it’s a color management issue. Using the correct ICC color profile for your printer, ink, and paper combination helps ensure your colors start accurate before you even press.

How to Prevent Sublimation Fading During Printing
Preventing sublimation prints from fading starts long before the first wash — it begins with your choice of materials, printing technique, and equipment calibration. Each variable in the printing stage directly influences how well the sublimation dye bonds to the substrate. By focusing on fabric composition, temperature control, and the quality of inks and papers, you can dramatically improve the color retention and print longevity of your sublimation designs.
Choose Polyester or High-Polyester Blends
Sublimation dyes chemically bond with polyester molecules when heated. This process forms a permanent bond inside the fiber rather than resting on the surface, which is why prints on polyester maintain their vibrancy much longer than those on cotton or other natural fibers.
- Use 100% polyester fabrics or substrates with a poly-coating (for mugs, tumblers, and plaques).
- If softness or stretch is a concern, aim for at least 65% polyester content — lower blends may look good initially but fade after a few washes.
- Avoid cotton unless using sublimation coating sprays or hybrid transfer methods.
| 💡 Fact: Studies show that sublimated prints on 100% polyester retain their colour significantly longer than prints on cotton — in one peer-reviewed test, polyester showed very low color loss after multiple washes, whereas cotton showed large ΔE shifts. (Imaging Science and Technology, 2024) |
Optimize Heat Press Settings
Incorrect heat or pressure is one of the most common causes of premature fading in sublimation prints. If the ink isn’t fully vaporized or the heat isn’t evenly distributed, colors won’t embed properly into the fibers, leading to dull or uneven results.
- Temperature: 380°F–400°F (193°C–204°C)
- Time: 45–60 seconds
- Pressure: Medium to firm (check your substrate’s specs)
Always run a test print before each major production run to verify consistent heat, pressure, and color transfer. Even minor variations — such as uneven heat plates, cold spots, or changes in room humidity — can cause partial sublimation and premature fading.

Use Professional-Grade Inks and Paper
Even with perfect heat and fabric, low-quality sublimation inks and transfer paper can drastically shorten print life. Cheaper inks often lack UV stabilizers or fade-resistant pigments, while poor-quality paper can cause uneven ink release and incomplete transfer.
- Choose fade-resistant inks from reputable brands (like Sawgrass, Epson, or Hiipoo). Look for inks labeled “UV-resistant” or “outdoor-rated.”
- Use high-release sublimation transfer paper, which ensures that the majority of the ink is transferred cleanly during pressing.
- Store your inks in a cool, dark place (59°F–77°F) and use them before the expiration date — degraded ink chemistry can reduce color stability.
Washing Sublimated Items: Proven Ways to Prevent Fading
Maintaining the vibrancy extends beyond the printing process. Proper care during washing will significantly impact the longevity of your creations. By following a few essential guidelines, you can ensure that your sublimated items retain their brilliance even after multiple wash cycles.
Let’s delve into these essential practices, beginning with the first step: washing in cold water.
Wash in Cold Water
Hot water can accelerate fading of sublimation prints by causing the ink to break down more quickly. Always wash sublimated items in cold water to minimize the risk of color loss. Additionally, turn the garment inside out before washing to further protect the print.
Avoid Fabric Softeners
Fabric softeners may make your clothes feel cozy, but they can negatively impact sublimation prints. These softeners slow the drying process of the clothing and may degrade the ink and cause fading. On top of this, softeners can discolor white ink and give it a yellowish tinge.
Air Dry or Use Low Heat
Using a dryer at high temperatures has a similar affect to washing in hot water. It can be harsh on sublimation prints and contribute to fading. Instead, allow items to air dry naturally. If you must use a dryer, opt for a low-heat setting to minimize potential damage.
Iron Inside Out While Damp
Direct heat on the printed surface will cause fading, which is why ironing your garments inside out is ideal. However, a great tip is to iron your clothing when slightly damp. You will notice this methods removes wrinkles easier than when the clothing is completely dry, but the dampness also protects your ink from the excessive heat coming from the iron.
| Factor | Common Mistake | Correct Practice |
|---|---|---|
| Fabric | Using cotton blends | Use 100% polyester |
| Heat | Uneven or low temperature | Calibrate and test regularly |
| Washing | Hot water | Cold water only |
| Drying | High heat | Air dry or low tumble |
Advanced Techniques to Make Sublimation Prints Last Longer
If you’re wondering how to make sublimation last longer, the key lies in consistent maintenance and environmental control. Consider these additional strategies to keep your sublimations looking vibrant:
- Store Inks Properly: Keep sublimation inks sealed and stored in a cool (59°F–77°F), dry place. Exposure to heat or light can degrade ink pigments, affecting print quality and color longevity.
- Pre-Treat or Pre-Press Materials: Remove excess moisture from fabrics and substrates before pressing. Moisture interferes with ink transfer and can cause uneven or faded areas.
- Perform Regular Test Prints: Running small test prints helps ensure consistent colors and detect early issues with ink flow, paper quality, or press performance.
Final Thoughts on Preventing Sublimation Fading
Sublimation durability depends on controlling a few predictable variables, heat, pressure, humidity, and material quality. When those factors stay consistent, fading becomes the exception, not the rule. Treat each project as a test of precision, not luck, and your prints will maintain their color integrity for years.
As sublimation technology evolves, durability is less about discovering new tricks and more about refining established methods. Testing, calibration, and environmental awareness are the real safeguards against fading.
