In this guide, we’ll take a detailed look at dye sublimation. You’ll learn how it works, its benefits for garments and other products, the process, and tips for achieving the best results. We’ll also compare it to other popular printing methods. By the end, you’ll understand why dye sublimation is so popular and how it can elevate your printing projects.
Let’s get started!
What is Dye Sublimation?
Dye sublimation printing is a process that uses heat to transfer dye onto specific materials. The term “sublimation” refers to the process where a substance transitions directly from a solid to a gas, bypassing the liquid state. In dye sublimation, solid dye particles are heated until they transform into a gas. This gaseous dye then permeates the material’s surface, bonding with its fibres or coating to create a permanent, vibrant print.
Unlike traditional printing methods, dye sublimation doesn’t simply layer ink on the surface of a material. Instead, it embeds the dye into the material itself. This results in a print that becomes part of the material, offering unmatched durability and vibrancy. The process is ideal for materials with a high polyester content or items coated with a special polymer layer.

The Dye Sublimation Process – How Does It Work?
Dye sublimation relies on a combination of heat sublimation, pressure, and specialised materials to achieve flawless integration between the design and the substrate. Here’s a detailed breakdown of how the dye sublimation process works:
Step 1: Design Creation
The process begins with the creation of a digital design. Graphic design software, such as CorelDraw, Adobe Illustrator or Photoshop, is often used to prepare high-resolution artwork. Dye sublimation works best on white or light-coloured surfaces. In this process, the designs are typically vibrant and include bold colours to take full advantage of the technology.
Key Tip: For accurate colour representation, use CMYK colour profiles and keep the design quality high (300 DPI or more).
Step 2: Printing onto Transfer Paper – h3
Once the design is ready, it is printed onto special sublimation transfer paper using sublimation ink. This ink is unique because it can convert from a solid to a gas when exposed to heat. A dye-sublimation printer is used for this step, ensuring that the design is crisp and the colours are vibrant.
Note: The design is printed as a mirror image to ensure it appears correctly when transferred onto the material.
Step 3: Preparing the Substrate
The next step involves preparing the material or surface being printed on—referred to as the substrate. For garments, this means ensuring the fabric is at least 65% polyester or has a polymer coating. A polymer-coated layer is essential for hard surfaces, such as mugs or photo panels, to ensure the dye bonds effectively.
Preparation Steps:
- Clean the surface to remove dust, lint, or oils.
- Ensure the substrate is dry to avoid inconsistencies during transfer.
Step 4: Heat and Pressure Application
The printed transfer paper is placed face-down onto the substrate, and both are positioned in a heat press. Depending on the material, the press is set to a specific temperature, pressure, and duration.
The standard heat and pressure settings are:
- Temperature: Around 200°C or 380 – 420°F
- Time: Between 40 and 50 seconds.
- Pressure: Medium to firm, ensuring even contact.
As the heat is applied, the sublimation ink on the transfer paper transforms into a gas. Simultaneously, the polyester or polymer coating fibres open up to absorb the dye, ensuring the ink bonds permanently with the substrate.
Step 5: Cooling and Finishing
Once the heat press cycle is complete, the substrate is allowed to cool. During cooling, the fibres close, trapping the dye and solidifying the design within the material. The transfer paper is then removed, exposing a vibrant and durable print.
Materials Suitable for Dye Sublimation
Dye sublimation printing is a versatile method, but its success depends on the materials used. Not all surfaces can effectively hold sublimation dye, as the process requires specific properties to bond the dye permanently. Below is an in-depth look at the types of materials that work best for sublimation printing.
Polyester-Based Fabrics
Polyester is the gold standard for dye sublimation. The molecular structure of polyester allows the dye to bond deeply during the sublimation process. It creates vibrant and long-lasting prints. Fabrics with at least 65% polyester content yield the best results. But why polyester? The dye integrates into the fibres rather than sitting on the surface, ensuring that the print won’t fade, crack, or peel over time.
It is commonly used to make custom apparel like T-shirts, hoodies, and activewear. It is also the best choice for sportswear, like jerseys, shorts, and leggings. You can also use this material for products that require soft furnishings, like cushions, pillowcases, and curtains.
Polymer-Coated Hard Surfaces
Hard surfaces, such as ceramics, metals, and glass, require a polymer coating to work with sublimation. The coating gives the substrate the necessary bonding properties to hold the dye effectively. The dye won’t bond without a polymer coating, resulting in incomplete or poor-quality prints.
Everyday products include personalised coffee mugs and tumblers, high-definition photo panels made from metal or ceramic, and polished promotional items like keychains and coasters.
Blended Fabrics
Fabrics that mix polyester and other materials can also be sublimated, but the polyester content must be high (at least 65%). The lower the polyester percentage, the less vibrant and durable the print will be. These blends are commonly used for uniforms that require added comfort or stretch.
Sublimation Blanks
Sublimation blanks are pre-made items specifically designed for sublimation printing. They are made from polyester or coated with a polymer to ensure consistent results. Examples include mouse pads, durable tote bags, ceramic or metal plates, and awards pre-coated for detailed designs.
Rigid Polymeric Materials
Pure polymer-based products, such as acrylic and certain plastics, can be sublimated and commonly used for signage, ID cards, and lightweight promotional items. These materials are lightweight yet durable and offer excellent colour retention, making them ideal for outdoor or high-use items.
Materials to Avoid
Natural fibres like cotton, wood, or uncoated surfaces cannot bond with sublimation dye, resulting in faded or incomplete prints.
Methods of Dye Sublimation
Dye sublimation is primarily divided into two key approaches: transfer dye sublimation and direct dye sublimation. Each type has distinct applications and is suited to specific materials and design requirements. Let’s explore these methods further to understand their processes, benefits, and best use cases.
| Application | Transfer Dye Sublimation | Direct Dye Sublimation |
|---|---|---|
| Garments | Custom t-shirts, activewear, and uniforms with vibrant, durable designs. | Dresses, sports uniforms, and scarves. |
| Hard Surfaces | Mugs, phone cases, plaques, and photo panels coated with a polymer layer. | Not applicable. |
| Home Décor | Cushions, curtains, and wall art. | Large rolls of fabric for upholstery or home furnishings. |
| Large-Scale Textile Printing | Not commonly used. | Rolls of fabric for apparel manufacturers or upholstery. |
| Soft Signage | Not commonly used. | Banners, flags, and trade show displays. |
Transfer Dye Sublimation
In transfer dye sublimation, the design is first printed onto sublimation transfer paper using specialised sublimation inks. The transfer paper is then placed onto the substrate, and heat and pressure are applied to transfer the design onto the material. This is the most widely used sublimation type and is compatible with soft and hard surfaces.
How It Works
- The design is printed as a mirror image onto the transfer paper.
- Heat and pressure turn the ink into gas, which bonds with the substrate’s fibres or coating.
- The transfer paper is peeled off, leaving the design embedded in the material.
Key Advantages
- Produces vibrant, high-definition prints with excellent detail.
- Works on various materials, including polyester fabrics and polymer-coated hard surfaces.
- Suitable for edge-to-edge printing on garments and large surfaces.
Limitations – h4
- Requires materials with high polyester content or polymer coatings.
- Slightly longer process due to the additional transfer step.
Direct Dye Sublimation
Direct dye sublimation eliminates the need to transfer paper by printing the design directly onto the substrate. This method is most effective for fabrics and textiles that are at least 65% polyester. The process is faster and is often used for large-scale textile production.
How It Works
- The fabric is pre-treated to ensure proper dye absorption.
- A wide-format dye sublimation printer prints The design directly onto the material.
- Heat and pressure are applied, permanently embedding the dye into the fabric fibres.
Key Advantages
- Eliminates the need for transfer paper, reducing waste and costs.
- Faster process for large runs, making it ideal for bulk fabric production.
- Produces seamless, durable designs with no risk of misalignment.
Limitations
- Limited to fabrics; cannot be used on hard surfaces or items requiring polymer coatings.
- Best suited for white or light-coloured polyester fabrics.
Advantages and Disadvantages of Dye Sublimation Printing
Dye sublimation printing is a popular choice for creating vibrant, durable designs, but like any technology, it comes with its own set of pros and cons. Here’s a comparison table of the advantages and disadvantages:
| Aspect | Advantages | Disadvantages |
|---|---|---|
| Print Quality | Produces vibrant, sharp, high-resolution designs | Limited to light-coloured materials; dark fabrics don’t work effectively. |

| Setup and Efficiency | Fast setup, great for small batches and custom projects. | Less cost-effective for bulk printing compared to screen printing. |
Maintenance and Care for Sublimated Products
Proper care is essential to maintain the vibrant colours and durability of sublimated garments and products. That is why we recommend you some tips on how to take care of your sublimated products:
- For garments, wash them in cold water and air dry. When ironing, use a low heat setting and place a cloth over the sublimated area to avoid direct contact.
- For sublimated hard products like mugs or photo panels, it is recommended that they be cleaned with a soft, damp cloth and mild soap.
- Sublimated items should also be kept away from prolonged exposure to extreme heat or direct sunlight, as these can cause fading.
Dye Sublimation vs Other Printing Methods
Dye sublimation stands out from other printing methods due to its unique process and superior results.
Unlike screen printing, dye sublimation is more durable because it embeds dye into the material rather than layering ink on top. This prevents cracking or peeling over time.
Sublimation delivers smoother, longer-lasting designs compared to heat transfer printing. Heat transfer applies a layer of vinyl or ink on the surface, which can eventually peel or crack, while sublimation integrates the dye into the material itself.
Dye sublimation also differs from direct-to-garment (DTG) printing. While both offer vibrant results, sublimation creates edge-to-edge, high-definition designs. This makes it ideal for garments or products requiring full-surface coverage.
