Sublimation ink is a specialized dye-based ink used in sublimation printing to create permanent, full-color designs on polyester fabrics and polymer-coated surfaces.
Unlike traditional printer ink, sublimation ink transforms into a gas when exposed to high heat and pressure, allowing the dye to bond directly with the material.
This process produces vibrant, durable designs that won't peel, crack, or fade over time, making sublimation a popular choice for creating custom stainless steel tumblers, ceramic mugs, apparel, and other personalized products.
Whether you're creating custom crafts for personal use or resale, understanding the ins and outs of sublimation ink will help you achieve professional-quality results.
In this guide, we'll explain everything crafters should know about sublimation ink, including how it works, what materials you can print on, printer and ink options, troubleshooting steps for fixing common problems, and how to choose high-quality sublimation blanks for long-lasting results.
What Is Sublimation Ink?
Sublimation ink is a dye-based ink that transforms into a gas when exposed to high heat and pressure. This gas can then bond to polyester fibers or polymer-coated surfaces.
This process creates vibrant, long-lasting designs that resist peeling, cracking, scratching, and fading. Because the dye becomes part of the material itself, sublimation prints retain the original surface texture without adding stiffness or thickness.
Sublimation ink also produces excellent image quality. With this specialized ink, you can decorate apparel and hard goods with vibrant colors, smooth gradients, fine lines, and sharp details. The vibrancy and detail far surpass those of other printing techniques, making sublimation the preferred process for numerous crafters.
When paired with the right sublimation printer, proper heat press settings, and high-quality sublimation blanks, sublimation ink can empower creators to produce permanent, eye-catching designs.
Sublimation Ink vs Regular Ink
At first glance, sublimation ink and regular printer ink may seem similar. However, they are designed for completely different purposes and produce very different results.
Regular ink is intended for printing directly onto paper. In contrast, sublimation ink is designed for heat-transfer applications in which the image is permanently bonded to a compatible substrate.

Can You Use Sublimation Ink for Regular Printing?
Technically, a sublimation printer and ink can print text and images onto regular paper.
However, sublimation ink is not designed for everyday document printing. Colors may appear different from what you see on screen, as the printed image is intended for the heat transfer process.
Additionally, you cannot use regular paper for the sublimation process; you need specialized sublimation paper designed to release dye effectively when heated.
If you're interested in the sublimation printing process, you will need to pair your sublimation ink with sublimation paper to get lasting results. You will also need compatible surfaces for sublimation.
What Materials Does Sublimation Ink Work On?
Sublimation ink only works on materials that contain polyester or have a polyester coating. The ink needs these polymers to bond during the heat transfer process.
The following materials are compatible with sublimation ink:
- 100% polyester fabric
- Polyester fabric blends
- Polymer-coated hard surfaces
These materials allow sublimation ink to turn into a gas at high temperatures and bond directly to the surface. This creates a permanent design that becomes part of the product, making it smooth to the touch.
While many polyester fabric blends can work for sublimation printing, the polyester content will directly impact the print quality. Higher polyester blends produce brighter colors and sharper detail. Lower polyester blends can still work, but often result in more muted prints.
For the best results on apparel, use fabrics that are at least 75% polyester.
When it comes to hard goods, the blank needs to have a smooth polymer coating designed for sublimation ink.
Luckily, there are plenty of polymer-coated hard goods that are perfect for sublimation, including sublimation tumblers, sublimation mugs, stainless steel water bottles, keychains, coasters, candle jars, and more.
It's also important to remember that sublimation works best on white or light-colored surfaces. This is the case for both fabrics and hard goods. Sublimation ink is transparent and does not include white. Printing on dark or black surfaces can result in dull, faded, or nearly invisible designs because there is no white ink to provide contrast or support color visibility.
Choosing the right sublimation blanks and fabrics is essential for achieving impressive design results. Even high-quality sublimation ink cannot print well on incompatible materials.
What Materials Does Sublimation Ink NOT Work On?
Sublimation ink does not work on materials that lack polyester or a polyester coating. Without these polymers, the dye cannot bond during the heat transfer process, so the design will not be permanent.
For this reason, sublimation will NOT properly bond to:
- Cotton and other natural fibers
- Untreated glass
- Uncoated ceramic
- Raw wood
- Untreated metal
- Standard plastic products
These materials cannot hold sublimation ink because they lack polyester fibers and polymer coatings. For that reason, the sublimation ink has nothing to bond with.
Additionally, sublimation ink will struggle to appear on dark or black materials because the ink is transparent. This is even the case if the substrate is polyester or polymer-coated. Without a light surface, colors will appear dull or may not show at all.
Now that you know the basics of sublimation ink, including compatible and incompatible materials, let's explore how the process works.
How Does Sublimation Ink Work?
Sublimation ink works by transforming into a gas under high heat and pressure. The gaseous dye then penetrates polyester fibers or a polyester-coated surface, creating a permanent bond within the material.
Unlike traditional printing methods, which place ink on top of a surface, sublimation embeds the design into the substrate itself. This is why sublimation prints can remain vibrant and durable for years.
Here are the five basic steps for how sublimation inks work:
Step 1: Print the Design
The process begins by printing a design onto sublimation paper using a sublimation printer.
The printed sublimation ink will remain in a solid form on the paper until you're ready to transfer it to your substrate.
Step 2: Position the Transfer
Next, place the printed sublimation paper against a compatible substrate. The sublimation ink should face the object's surface.
You then secure the design with heat-resistant tape to prevent it from shifting during the sublimation process.
Proper placement will help ensure your design details are sharp and properly aligned.
Step 3: Apply Heat and Pressure
You will then apply heat and pressure to embed the dye-sublimation ink into your substrate. Use a sublimation heat press or sublimation oven to transfer your ink.
As the temperature rises, the sublimation ink undergoes a unique transformation. Instead of becoming a liquid, the dye changes directly from a solid into a gas.
Step 4: The Dye Bonds with the Material
As the dye sublimates into a gas, it diffuses into polyester fibers or polymer coatings under heat and pressure.
The heat increases molecular mobility in the polyester, allowing the dye to penetrate the polymer structure.
This creates a permanent transfer rather than a surface-level print.
Step 5: Cooling and Setting
Once you turn off the heat, the object will begin to cool.
As it cools, the design becomes locked within the substrate and remains part of the material.
This finished sublimation ink print is highly resistant to peeling, cracking, and scratching, making it durable enough for long-term everyday use.

What Printers Use Sublimation Ink?
Not every printer is equipped to handle sublimation ink. You need to purchase a dedicated sublimation printer or an inkjet printer that can be converted to sublimation printing.
Here are the main differences between a dedicated sublimation printer and a converted inkjet printer:
Dedicated Sublimation Printers
Dedicated sublimation printers are built specifically for dye-sublimation printing.
These machines are designed to work exclusively with sublimation ink, ensuring consistent color output and reliable performance.
It's better to purchase a dedicated sublimation printer rather than a converted inkjet printer, as it can deliver more consistent, professional results. It also has a lower risk of maintenance issues and print quality problems over time.
That said, sublimation printers are often more costly than converted inkjet printers.
Converted Inkjet Printers
Many beginners choose converted inkjet printers as a more affordable entry point into sublimation printing.
The most common converted option is the Epson EcoTank. Crafters convert these printers by filling them with sublimation ink instead of standard inkjet ink.
While less expensive than sublimation printers, these types of devices are not designed for sublimation printing. For that reason, they may experience maintenance issues, such as clogging and printhead damage. Plus, using the device outside of its intended purpose may void its warranty.
Choosing the Right Printer for Sublimation Ink
If you decide to choose a purpose-built sublimation printer, you can find many high-quality options online.
Two of the most popular and trusted brands are Epson and Sawgrass printers.
In addition to the converted EcoTank, Epson features a variety of printers for professional crafting, including the SureColor F170 and the F570 Pro.
The Epson SureColor F170 is a compact entry-level sublimation printer, while the F570 Pro is a large-format option designed for higher-volume production and wider prints.
Sawgrass, on the other hand, features two great devices for sublimation crafting: the Sawgrass SG500 and SG1000.
The SG500 is built for straightforward desktop crafting that's ideal for drinkware. The SG1000 expands the same system into larger print sizes and higher production capacity. The printer is ideal for commercial production and larger crafts.

Common Sublimation Ink Problems and Solutions
Once you have a sublimation printer and ink, you need to avoid common mistakes that can affect print quality and your device's health.
Most problems come down to ink quality and compatibility, printer settings, and material compatibility.
Below, we explain common sublimation problems and their solutions.
Dull or Faded Colors
One of the most common sublimation ink problems is washed-out or dull prints.
This usually happens when the heat press temperature is too low, the press time is too short, or the sublimation blanks are of low quality.
Here's how to fix this issue:
- Increase your heat source's temperature within the recommended ranges
- Extend press time slightly
- Use high-quality sublimation blanks or fabrics with higher polyester content
If the issue continues, verify that your blanks are designed for sublimation and that you're using compatible ink.
Using Incompatible or Low-Quality Ink
Using low-quality ink or ink that is incompatible with your printer can lead to poor color accuracy, inconsistent transfers, clogged print heads, and reduced durability.
It's critical to use sublimation ink designed for your printer model. For example, Sawgrass printers are designed to work with Sawgrass sublimation ink, while Epson sublimation printers should use compatible Epson sublimation ink systems. Using the wrong ink can lead to performance issues.
Your sublimation ink's shelf life and storage conditions can also impact its quality over time. Sublimation ink should be stored in a cool, dry location away from direct sunlight.
Expired or improperly stored ink may separate and lose color performance, leading to disappointing printing results.
Make sure to use sublimation ink designed for your printer, store it properly, and use it before it expires.
Print Head Clogs
Clogged print heads can be a serious issue with sublimation printing, and this problem is especially common with converted inkjet printers.
Additionally, using expired ink or infrequently using your printer can also lead to clogging issues.
Here are the primary ways to avoid clogging issues:
- Use a printer designed for sublimation
- Run nozzle checks
- Print at least once weekly
- Store ink properly
- Keep printers in low-humidity environments
- Use quality sublimation inks
- Don't use expired ink
- Avoid mixing ink brands
If you notice missing colors, streaks, or inconsistent print quality, perform a nozzle check and cleaning cycle as soon as possible. This will help prevent minor clogs from developing into more serious print head issues.
Ghosting or Blurry Transfers
Ghosting occurs when the design shifts during the heat transfer process. This results in a faint duplicate image or blurred edges, reducing image sharpness and detail.
Here's how to prevent ghosting:
- Secure sublimation paper tightly with heat-resistant tape
- Ensure even pressure during pressing
- Use high-quality sublimation blanks that fit your heat press correctly
Taking the time to properly secure your design before pressing is one of the simplest and most effective ways to achieve sharp, professional-looking sublimation transfers.
Uneven or Patchy Prints
Uneven prints often come from inconsistent pressure or poor contact between the transfer paper and the substrate. Excessive humidity and low-quality blanks can also lead to patchy printing results.
To get consistent results across the substrate, make sure to:
- Preheat your heat press or sublimation oven
- Ensure full contact between the printed design and the blank's surface
- Use flat, high-quality sublimation blanks
- Store your blanks and other supplies in low-humidity environments
- Use a shrink wrap or silicone sleeve if you're using a sublimation oven
- Pre-press fabrics briefly to remove moisture before applying the design
Achieving professional results often comes down to ink quality, substrate compatibility, securing the design, using correct heat-press settings, and avoiding moisture. These factors work together to produce vibrant, durable sublimation prints.
Plus, you need to use high-quality sublimation blanks specifically designed for the heat-transfer process to achieve the best results.
Where to Buy the Best Sublimation Blanks for Sublimation Ink
Sublimation ink performs best when paired with the right substrates. This is why choosing high-quality sublimation blanks is just as important as selecting the right sublimation printer and ink.

Sublimation Ink FAQs
What Is Sublimation Ink Made Of?
Sublimation ink is made from dye particles suspended in a liquid carrier designed for heat-transfer printing. These dye particles are formulated to turn into a gas when exposed to high heat and pressure, allowing them to bond with polyester fibers or polymer-coated surfaces. The ink formulation is carefully engineered to produce vibrant colors, smooth gradients, and durable prints when used with sublimation printers and sublimation blanks.
Does Sublimation Ink Wash Out?
Sublimation ink does not wash out when it is properly applied to polyester or polymer-coated materials. During the sublimation process, the ink becomes part of the substrate at a molecular level, making the design resistant to washing, peeling, and fading. If you apply sublimation ink to natural fibers or uncoated surfaces, it will not bond properly and will wash out.
How Long Does Sublimation Ink Last?
Sublimation ink can last for years when properly transferred onto compatible materials using a heat press or sublimation oven. However, if you have not yet printed and transferred your sublimation ink, it will likely expire within one to two years.
Where Can I Buy Sublimation Ink?
You can purchase sublimation ink from specialty printing suppliers, online craft retailers, and manufacturers specializing in sublimation printing systems. You can purchase Sawgrass sublimation printers and ink at The Stainless Depot Company.
What Are the Disadvantages of Using Sublimation Ink?
The main disadvantage of using sublimation ink is that it only works with polyester fabrics and polymer-coated hard goods. Sublimation ink cannot bond with 100% cotton fabrics and other non-polyester materials. Plus, results will not appear as vibrant and bright on black and dark substrates.
What Do You Use Sublimation Ink For?
Crafters and businesses use sublimation ink to create eye-catching custom products, such as tumblers, mugs, apparel, home décor, and promotional items. The sublimation process can empower you to produce vibrant, eye-catching products for personal use or resale.
Is Sublimation Ink Eco-Friendly?
Yes. Many crafters choose sublimation ink and printing because it is more eco-friendly than other printing methods. Generally, the sublimation process generates minimal waste compared to other printing techniques, like vinyl and screen printing.
