How Long Does Sublimation Ink Last? Does it Go Bad?

Sublimation ink is widely used for creating high-quality and long-lasting prints on various surfaces, including fabrics, ceramics, metals, and plastics.

But like any other ink, sublimation ink has a shelf life, and it’s essential to know its storage requirements to prevent it from going bad.

So, how long does sublimation ink last, and does it go bad?

Sublimation ink can last for up to two years if stored correctly. Proper storage includes keeping the ink in a cool, dry place away from direct sunlight and heat sources. Once the ink is opened, it has a shelf life of six months to a year, depending on individual factors and how it is stored.

What Is Sublimation Ink?

Sublimation ink is a unique type of ink that is used with a sublimation printer to apply designs or graphics onto various surfaces through a heat transfer process. This printing method is becoming increasingly popular due to its durability and longevity.

The sublimation process involves printing a design on transfer paper using sublimation ink and then transferring the design to the desired surface through a combination of heat and pressure. The ink converts from a solid state to a gas, actually dying the fibers and locking it in for permanence.

Sublimation ink is widely used in the fields of apparel, sports, and promotional products because of its exceptional resistance to fading and cracking. It provides bright, vivid colors that do not easily fade over time, even with frequent washing and exposure to sunlight.

How Long Does Sublimation Ink Last?

Sublimation ink has a shelf life, and it’s essential to consider several factors that affect its life span such as storage conditions, the frequency of use, and whether it’s opened or unopened.

Unopened Sublimation Ink

Unopened sublimation ink can last for up to two years if stored correctly. Proper storage includes keeping the ink in a cool, dry place away from direct sunlight and heat sources. When stored correctly, the ink can maintain its color vibrancy and quality for the duration of its life span. However, if stored incorrectly or left unused for years, it can go bad, leading to poor quality transfers, or worse, clogging the printer’s nozzles.

Opened Sublimation Ink

Once the sublimation ink bottle is opened, its shelf life is greatly reduced. The ink can last from six months to a year, depending on individual factors, how it is stored, how frequently it is used, and whether the cap is tightly closed to prevent air from getting in.

To extend the life of opened sublimation ink, store it in a cool, dry place out of direct sunlight and heat sources. Consider testing it on transfer paper before using it on the substrate surface to ensure that it hasn’t gone bad and still provides the desired color vibrancy.

It’s worth noting that expired sublimation ink could produce subpar dye sublimation transfers that have washed-out colors and may not adhere well.

How to Tell If Sublimation Ink Has Gone Bad?

Fading Colors

If the colors on your transfer print start to look washed out or faded, it’s a sign that your sublimation ink could have expired. Faded colors are an indication that the dyes have started to break down and cannot bind correctly to the substrate anymore.

Clogging Print Head

Dried, clogged nozzles are a common issue with expired ink. When ink sits in the printer for an extended period, it can dry and solidify, leading to clogged nozzles. If you notice streaks, smudges, or missing colors on your transfer prints, clogged nozzles could be the culprit.

Separation of Ink Colors

Sublimation ink contains dyes suspended in a liquid vehicle. Over time, the solvent in the vehicle can evaporate, causing the dyes to separate and “settle” at the bottom of the ink bottle. If you notice ink settling or separation, it’s best to dispose of the ink and buy fresh ink.

Unusual Smell

Another way to determine if the ink has expired is to sniff it. Fresh sublimation ink has a slightly sweet smell, while expired ink may produce an unusual sour or rancid odor.

How to Store Sublimation Ink?

The key to maintaining the quality of sublimation ink is proper storage. The following tips can help extend the life span of sublimation ink:

Use Airtight Containers

Sublimation ink is susceptible to air, moisture, and light, which can all interfere with the quality of the ink. The best way to keep the ink fresh is to store them in airtight containers like bottles or jars.

Keep Ink in Cool, Dry Places

When exposed to heat and humidity, ink can easily turn bad. Therefore, it is essential to store sublimation ink in cool, dry, and dark places.

Store your ink bottles in a cool and dry space that is away from direct sunlight, heat sources, and moisture, such as a closet or drawer. Temperature-controlled environments are the best options for storing sublimation ink, especially when it comes to summer storage and high humidity areas.

Follow Printer and Ink Manufacturers’ Recommendations

Different printers and ink brands have various storage requirements and recommendations. It would be best to follow the specific instructions provided in the instruction manual of your printer and the ink manufacturing company on how to store and handle sublimation ink.


Sublimation ink is an essential component of the dye-sublimation process used to transfer designs and graphics onto various substrates. Proper storage, both before and after it is opened, is necessary to maintain the color vibrancy and quality of the ink.

Sublimation ink can last for up to two years if stored correctly and unopened. Once opened, the shelf life is reduced to six months to a year, depending on various factors. Signs of sublimation ink going bad include clogging of the printer’s nozzles, faded prints, unusual smells, and separation of ink colors.

By following the storage requirements provided by the ink manufacturer, using airtight containers, keeping ink in cool, dry places away from direct sunlight and heat sources, your sublimation ink can stay in good condition for a long time.
