How to Protect Sublimation Items from Fading

Sublimation is popular with crafters and small business owners because it creates bright, colorful designs that become part of the material instead of sitting on top like vinyl or paint. When done correctly, sublimation prints are known for being long-lasting and resistant to cracking or peeling. The dye is transferred with heat, pressure, and time, and the material absorbs the ink during the process.

However, sublimation items can still fade if they are made on the wrong blanks, washed incorrectly, exposed to too much direct sunlight, or cleaned with harsh products. The good news is that most fading can be prevented with the right materials and simple care habits.

Why Do Sublimation Items Fade?

Before you can protect sublimation items from fading, it helps to understand why fading happens in the first place.

Sublimation works best on polyester fabric or sublimation-coated blanks. Natural fibers like cotton do not hold sublimation dye well, which means the design may look dull or wash out quickly. Sublimation also works best on white or very light-colored surfaces because sublimation ink does not include white ink and cannot lighten a dark background.

Fading usually happens for one of these reasons:

• The item was made with too much cotton or the wrong material.
• The blank was not designed for sublimation.
• The heat press settings were incorrect.
• The item was washed in hot water or dried with high heat.
• The item was cleaned with bleach, fabric softener, abrasive scrubbers, or harsh chemicals.
• The item was left in direct sunlight for long periods of time.
• The item was stored in a hot car, damp area, or bright window.

Sublimation is durable, but it is not completely maintenance-free. Proper care makes a big difference.

Start with the Right Blank

The best way to protect sublimation items from fading begins before you ever press the design. Choose a blank that is actually made for sublimation.

For shirts, bags, pillow covers, and fabric items, use a high-polyester fabric. The higher the polyester content, the better the sublimation dye can bond with the material. Lower polyester blends may create a faded or vintage look, but they usually will not stay as bright after repeated washing.

For mugs, tumblers, coasters, keychains, ornaments, and photo panels, use blanks with a sublimation coating. Regular ceramic, metal, wood, or glass items will not accept sublimation properly unless they have a special coating designed for the process.

If you sell sublimation products, this is one area where it is worth buying better-quality blanks. Cheaper blanks may save money at first, but they can lead to dull color, poor transfer, or customer complaints later.

Use the Correct Heat Press Settings

Fading is not always caused by washing. Sometimes a design looks faded because it was never pressed correctly in the first place.

Sublimation depends on the right combination of time, temperature, and pressure. Sawgrass notes that quality results depend on suitable substrates, a calibrated heat press, smart color management, manufacturer guidelines, testing, and practice.

If your sublimation print looks faded right after pressing, check:

• Was the temperature high enough?
• Was the pressure even?
• Was the item pressed long enough?
• Was the blank recommended for sublimation?
• Was the design printed with the correct sublimation ink and paper?
• Did the transfer shift during pressing?
• Was there moisture, lint, oil, or dust on the blank?

Sawgrass also explains that inconsistent color may point to heat press issues, especially if some areas look faded while others look bright.

A good habit is to keep a sublimation testing notebook. Write down the blank brand, temperature, press time, pressure, paper type, ink type, and results. This helps you avoid repeating mistakes and gives you a reliable guide for future products.

Wash Sublimation Clothing the Right Way

For sublimation shirts, totes, pillow covers, and other washable fabric items, washing habits matter. Cricut’s care instructions for Infusible Ink apparel blanks recommend washing items inside out with cold water and mild detergent, then tumble drying on low or line drying. Cricut also says to avoid fabric softener, dryer sheets, and bleach.

That same basic care routine works well for many sublimated fabric products:

1. Turn the item inside out before washing.
   This helps reduce friction against the printed side.
2. Use cold water.
   Hot water can be harder on both the fabric and the print.
3. Choose a mild detergent.
   Harsh detergents and stain removers may shorten the life of the design.
4. Skip bleach and fabric softener.
   Bleach can damage color, and fabric softener can leave residue.
5. Use low heat or hang dry.
   High dryer heat can age the fabric and print faster.
6. Avoid ironing directly over the design.
   If ironing is needed, use low heat and press from the reverse side when possible.

For handmade sellers, include these instructions with every sublimation shirt or tote. A simple care card can prevent a lot of fading problems.

Protect Sublimation Tumblers and Mugs

Tumblers and mugs need different care than shirts. Even if a tumbler blank is advertised as dishwasher safe, handwashing is usually the safest option for keeping the design bright as long as possible.

Cricut’s mug care guidance says Cricut mug blanks may be hand washed or placed in a dishwasher, but they should not be cleaned with steel wool, colored cleansing agents, or scrubbing pads. Creative Dye also notes that dishwasher safety depends on the tumbler manufacturer and recommends handwashing without soaking for best results.

For sublimation drinkware, use these care tips:

• Hand wash with mild soap and warm water.
• Use a soft sponge or cloth.
• Do not soak for long periods.
• Do not scrub with steel wool or abrasive pads.
• Avoid bleach and harsh cleaners.
• Do not place in the freezer.
• Do not leave in a hot car.
• Follow the manufacturer’s dishwasher guidance if the blank is marked dishwasher safe.

For tumblers with lids, straws, rubber bottoms, or special coatings, handwashing is especially important because extra parts can wear out faster than the sublimated surface.

Keep Sublimation Items Away from Direct Sunlight

Sunlight is one of the biggest causes of fading. Even durable sublimation items can lose brightness when they sit in direct sunlight for long periods.

INNOSUB recommends storing sublimation blanks in a dry, cool place and avoiding direct sunlight because it can cause sublimation prints to fade over time. Creative Dye also notes that sublimation prints can fade in direct sunlight and should be stored in a cool, dark place.

This matters most for:

• Car coasters
• Car fresheners
• Garden flags
• Outdoor signs
• Window displays
• Metal photo panels
• Tumblers left in vehicles
• Shirts stored near sunny windows

If you make items for outdoor use, choose blanks specifically designed for outdoor exposure. For example, ChromaLuxe Outdoor is made with a UV-resistant coating and has outdoor performance ratings tied to ink type, placement, and environmental factors.

For regular indoor sublimation blanks, do not assume they will hold up outside indefinitely. Outdoor use requires outdoor-rated materials.

Avoid Harsh Cleaning Products

Harsh cleaners can make sublimation items fade, scratch, or look cloudy. For hard blanks like coasters, mugs, ornaments, and photo panels, avoid anything abrasive.

Cricut recommends cleaning ceramic and square coaster blanks with warm water and glass cleaner, while avoiding steel wool, colored cleansing agents, and scrubbing pads. INNOSUB also recommends mild, non-abrasive cleaning products and warns against bleach and abrasive cleaners.

Use gentle cleaning supplies such as:

• Mild dish soap
• Soft microfiber cloths
• Non-abrasive sponges
• Warm water
• Glass cleaner when appropriate for the blank

Avoid:

• Bleach
• Acetone
• Magic erasers on printed areas
• Steel wool
• Rough scrub pads
• Strong degreasers
• Abrasive powders
• Colored cleaners that may stain

When in doubt, clean gently and test a small area first.

Store Sublimation Items Properly

Storage is often overlooked, but it can help prevent fading and damage. Sublimation items should be stored away from direct sunlight, moisture, and high heat. INNOSUB recommends cool, dry storage and says sublimation products should be stored flat or hanging to prevent wrinkles and creases.

For clothing, fold or hang items in a closet instead of leaving them in direct sunlight. For tumblers and mugs, store them in a cabinet rather than on a sunny windowsill. For signs, ornaments, and coasters, keep them in a dry space where they will not rub against rough surfaces.

If you sell sublimation products at craft fairs, protect inventory while transporting it. Do not leave sublimation items sitting in a hot vehicle for hours, especially during summer. Heat and sunlight together can be hard on coatings, fabric, and color.

Should You Seal Sublimation Items?

Many crafters ask whether they should add a spray sealer, clear coat, epoxy, or UV spray over sublimation items.

The answer depends on the item.

For most sublimation shirts, bags, and fabric products, you do not need a sealer. The dye should already be infused into the polyester fibers. Adding a coating to fabric can change the texture and may not wash well.

For hard goods, a sealer is not always necessary either. A quality sublimation blank already has a coating designed to receive the dye. Adding another layer may cause cloudiness, yellowing, streaking, or peeling if the product is not compatible.

However, if you are making outdoor signs, garden markers, car accessories, or items that will face direct sunlight, you may want to test a UV-resistant coating. Always test on one sample first before selling the item. Make sure the finish does not affect color, food safety, drinkware safety, or washing instructions.

The best protection is still choosing the correct blank for the item’s intended use.

Customer Care Card Example

Common Mistakes That Make Sublimation Fade Faster

Here are some of the most common mistakes to avoid:

Using Cotton Shirts

Cotton does not hold sublimation dye the way polyester does. The print may look soft, dull, or faded after washing. Use polyester or a high-poly blend for the best results.

Washing with Hot Water

Hot water can be too harsh for sublimated fabric items. Cold water is usually the safer choice for keeping colors bright.

Using Bleach or Fabric Softener

Bleach, fabric softener, and dryer sheets are commonly discouraged in sublimation care instructions because they can damage or dull the print.

Scrubbing Hard Blanks

Abrasive scrubbers can scratch coated sublimation surfaces. Use soft cloths and mild cleaners instead.

Leaving Items in the Sun

Direct sunlight can fade sublimation prints over time, especially if the item is not rated for outdoor use.

Ignoring Manufacturer Instructions

Different blanks have different coatings and care requirements. Always check the care instructions from the blank supplier, especially for drinkware and outdoor products.

Final Thoughts

Sublimation items can last a long time when they are made and cared for correctly. The key is to start with the right blank, use proper heat press settings, avoid harsh washing and cleaning methods, and protect items from direct sunlight and extreme heat.

For makers, the biggest takeaway is this: fading prevention starts before the customer ever receives the product. Choose quality blanks, test your settings, and include clear care instructions with every order. For customers, a little extra care—cold water, mild detergent, low heat, gentle cleaning, and smart storage—can keep sublimation items bright and beautiful much longer.
