Tired of your favorite sublimation prints fading after washing? Learn proven techniques to keep your sublimated garments vibrant and long-lasting!
Have you ever been disappointed when your sublimation prints started fading after a few washes? You're not alone. Many face this issue. Sublimation printing offers beautiful designs with incredible detail, but maintaining that appearance requires proper care and attention. The good news is that with some techniques and preventive measures, you can extend the life of your sublimation prints and keep them looking new wash after wash.
In this article, we'll explore why sublimation prints fade and share some tips to prevent this common problem. Whether you're a small business owner selling custom clothes or simply want to preserve your items, these tips will help you maintain the quality of your sublimation prints for much longer.
Sublimation printing is a digital printing method that uses heat to transfer dye onto polyester fabrics, ceramics, and polymer-coated items. Unlike traditional printing methods that put ink on top of the material, sublimation works through a cool chemical process.
During sublimation, special inks turn from solid to gas when heated (skipping the liquid phase – hence the term sublimation). The gas then penetrates the polymer fibers or coating and bonds with them as it cools. This makes the print part of the material rather than on top of it.
This integration has several benefits; the design won’t crack, peel, or wash away easily, the prints feel soft and seamless on fabrics, full-color, photographic images with great detail are possible, and the entire surface can be printed edge to edge.
Before we get into prevention techniques, let’s talk about why sublimation prints fade in the first place. Knowing these reasons will help you address the root causes:
Commercial laundry detergents have harsh chemicals, optical brighteners, and bleaching agents that break down the molecular bonds between the sublimation dye and the polyester fibers. These chemicals gradually weaken the dye’s bond to the fabric, and colors will appear less vibrant over time.
Hot water washing can reactivate the sublimation process and cause the dyes to release from the fabric. Since sublimation is a heat transfer process, washing in hot water essentially reverses the process to some degree and allows tiny amounts of dye to escape with each hot wash.
Mechanical agitation during washing, especially in high-speed wash cycles, creates friction between fabric fibers. This constant rubbing action can wear down the surface where the sublimation dye resides and cause fading over time.
UV rays are notorious for breaking down dyes of all kinds, and sublimation prints are no exception. Direct sunlight exposure can cause significant fading, especially for items like outdoor flags, banners, or clothing worn frequently in sunny conditions.
Sometimes fading issues come from problems with the original printing process. Insufficient heat, pressure, or time during the sublimation transfer can cause incomplete bonding between the dye and the material and make the prints more prone to fading later.
Now that we know who to blame for fading, let’s talk about how to keep your sublimation prints looking good for much longer:
Washing sublimated items the right way can make all the difference in how they look after washing. When you turn your sublimated garments inside out, you minimize direct contact with the printed surface. Cold or lukewarm water (never hot) prevents the sublimation process from reactivating. Gentle wash cycles with minimal agitation are a must.
Don't overcrowd the washing machine; give those garments some room to move. Hand washing delicate or valuable items is the most gentle approach of all. Take your custom sublimated t-shirts, for example. Turning them inside out and using a gentle cycle with cold water can make a difference.
When it comes to detergents, not all are created equal. You want mild, color-safe detergents for bright colors. Avoid anything with bleach or optical brighteners. pH-neutral detergents are a good choice for delicate fabrics. Liquid detergents dissolve better than powder, and measuring the right amount is crucial to avoid leaving residue that affects print quality.
Many crafters swear by Woolite Dark or other detergents designed for dark colors. Those are generally gentler on dyes.
Drying sublimated items correctly is just as crucial as the process itself. That means you want to dry them in a way that preserves their quality. Air drying is usually the best option. Hang your items in a shaded area out of direct sunlight's reach. If you do need to use a dryer, the lowest heat setting is your best bet.
It's also a good idea to remove items while they're still slightly damp and let them air dry from there. When it comes to dryer sheets, use them sparingly. Some contain chemicals that can affect sublimation dyes. And don't over-dry your items. That can cause excessive heat, which is the last thing you want.
Sublimation prints start to fade, and that fading is permanent. That means you can't completely restore them. But you can slow down further fading and maybe even enhance what you've got by taking a few simple steps.
First, switch to those gentler washing techniques we talked about earlier. You can also try a color-enhancing spray designed for synthetic fabrics. If an item is severely faded, overdyeing it with similar colors might help. For really valuable items, professional color restoration services can offer some improvement.
Sublimation printing produces designs that look great—and stay that way—for years to come. With a little know-how and some TLC, you can keep your sublimated products looking their best. That means washing them in cold water, using gentle detergents, keeping them out of direct sunlight, and drying them the right way.
The quality of the sublimation process itself also makes a big difference in how long those results last. That's why partnering with experienced printers who use top-notch materials and techniques is so important. It gives you a solid foundation for lasting results.
