How is the sublimation printing process done?
The sublimation printing process involves printing a design onto a special sheet of paper and then transferring that image onto another material, usually polyester or a polyester mix. The ink is heated until it turns into a gas and permeates the fabric, creating a molecular bond that results in a high-quality, permanent print.
Step 1: Prepare the Design
First, create a high-quality sublimation design using software such as Adobe Illustrator or Canva. Consider the shirt size and design placement. Alternatively, choose an existing image or photograph with a resolution of at least 300 DPI.
Step 2: Print the Design
Load the sublimation printer with sublimation ink and paper. Adjust the printer settings for sublimation printing, including paper type and print quality. Print the design, ensuring it is centred and mirrored if necessary. Allow the transfer paper to dry completely before trimming it to the desired size and shape.
Step 3: Prepare the Shirt
Preheat the heat press according to the manufacturer's instructions. Use a lint roller to remove any debris from the shirt. Place the shirt on the heat press, ensuring it is flat and smooth. Pre-press the shirt for a few seconds to remove wrinkles and moisture, ensuring the ink will be absorbed evenly.
Step 4: Transfer the Design
Position the printed design face down on the shirt, securing it with heat-resistant tape. Place a piece of protective paper, such as butcher paper or parchment paper, on top of the design to prevent ink transfer to the heat press. Close the heat press and apply pressure. The recommended settings are typically around 385 °F for 45–60 seconds.
Step 5: Cool and Remove Transfer Paper
Allow the sublimation shirt to cool completely before carefully removing the transfer paper. Peel off one corner of the paper and gradually work your way towards the other corner to avoid damaging the print or fabric.

What are the benefits of sublimation printing?
Sublimation printing is a process that uses heat and pressure to turn solid sublimation ink into a gas, which then permeates the polyester fibres of the T-shirt, creating a molecular bond that results in a high-quality, permanent print. This method ensures that the design becomes a part of the material rather than sitting on the surface, resulting in a smooth, seamless, and durable finish. Here are some benefits of sublimation printing:
- Vibrant and Long-lasting Prints: The molecular bond formed during sublimation results in exceptionally high-quality prints that resist fading over time. The colours remain vibrant and vivid, even after multiple washes.
- Seamless Finish: Unlike other printing methods, such as heat transfer vinyl or screen printing, sublimation printing ensures that the design becomes a part of the fabric. This results in a seamless and smooth finish without any raised or textured surfaces.
- Eco-friendly Option: Sublimation printing requires minimal water and produces less waste compared to other printing methods. It is an environmentally responsible choice for those who want to minimise their impact on the planet while creating stunning apparel.
- Customisation and Design Flexibility: With sublimation printing, you can transfer any design that your printer can create onto the T-shirt. This includes high-quality PNG files, designs with gradients, and even photographs. The possibilities for creativity are endless, allowing you to showcase your unique style and brand.
- Efficiency: Once you have the necessary equipment and have mastered the process, sublimation printing can be a fast and efficient way to create custom T-shirts. The printing process itself is quick, and the results are long-lasting.

What are the limitations of sublimation printing?
Sublimation printing is a popular method for creating custom t-shirts with vibrant, full-colour designs. While this printing method offers many advantages, there are also some limitations to be aware of. Here are some of the key constraints of sublimation printing to consider:
- Fabric Limitations: Sublimation printing works best with polyester fabrics. This is because the sublimation process involves turning solid dye particles into a gas, which then penetrates the surface of the fabric and turns back into a solid, permanently dyeing the fabric. Polyester is synthetic and therefore well-suited to this process. Natural fabrics like cotton have a much lower polyester content, so the dye does not bond as effectively, resulting in a faded or washed-out appearance over time. For this reason, sublimation printing is typically limited to garments that are 100% polyester or have a very high polyester content.
- Design Complexity: While sublimation printing offers incredible colour accuracy and the ability to print intricate designs, there are some design limitations to consider. Due to the way the ink is applied and bonded to the fabric, very small text or intricate details may not always be reproduced clearly. Extremely thin lines or small details may blur or become distorted, especially if the garment is stretched or worn over time. Additionally, sublimation printing is typically limited to flat surfaces, so printing on seams or over zippers and pockets is generally not possible.
- Colour Limitations on Non-White Fabrics: One of the biggest advantages of sublimation printing is the ability to produce a wide range of colours, including gradients and photorealistic images. However, this advantage is mostly limited to white or very light-coloured fabrics. When printing on darker fabrics, the colours may not appear as vibrant since the dye is somewhat transparent and the colour of the fabric will influence the final appearance of the design. For this reason, sublimation printing is typically recommended for light-coloured garments to ensure the design stands out and appears true to the original artwork.
- Durability Concerns: While sublimation printing produces long-lasting designs that won't crack, peel, or fade like other printing methods, there are still some durability concerns to be aware of. The dye is susceptible to UV rays, so prolonged exposure to sunlight can cause the colours to fade over time. Additionally, since the design is permanently bonded to the fabric, it will not withstand extremely high temperatures, which can cause the dye to turn gaseous and potentially ruin the design. Therefore, special care must be taken when washing and drying sublimation-printed garments to ensure they last as long as possible.
- Higher Production Costs: Sublimation printing can be more expensive than other printing methods, especially for smaller quantities. This is because the process requires specialised equipment and ink, and the setup costs can be significant. While the per-unit cost can be lower for larger quantities, small batches or one-off custom prints may incur higher costs. This is an important consideration for those looking to produce custom t-shirts on a budget.
In conclusion, while sublimation printing offers a range of benefits, including vibrant colours and durable designs, it is important to be aware of these limitations to ensure the final product meets expectations. Understanding the constraints of this printing method will help ensure that the design, fabric choice, and care instructions are optimised for the best possible outcome.

How does sublimation printing compare to other methods?
Sublimation printing is a process that uses high heat and pressure to transfer a design from sublimation paper directly onto a chosen product. It differs from traditional printing methods in that it uses heat and pressure to turn sublimation inks into gas, fusing with the material. This results in a higher-quality print that is less prone to cracking or fading.
Sublimation vs Screen Printing
Screen printing is a traditional printing method that has been used for centuries. It uses a stencil and applies layers of ink onto the printing surface. Each colour is applied using a different stencil, and the ink is thicker than in digital printing, resulting in brighter, more vibrant colours, especially on darker shirts.
Quality and Versatility
Both sublimation and screen printing deliver high-quality, vibrant results, but sublimation is more flexible with complex, multicoloured designs. Screen printing requires a separate screen for each colour, limiting its effectiveness for multicoloured designs. Sublimation, on the other hand, produces detailed, full-colour images without the need for numerous screens.
Cost Efficiency
Sublimation printing costs remain consistent regardless of design complexity, whereas screen printing costs increase with the addition of colours and screens. Therefore, sublimation is often the more economical option for smaller orders or designs with a broad colour palette.
Material Limitations
Sublimation printing is mainly limited to polyester and synthetic fabrics, while screen printing accommodates a wider range of materials, including cotton, nylon, and non-textile surfaces like glass and metal.
Durability
Sublimation prints are more durable because they integrate into the fabric, offering enhanced resistance to wear and tear. Screen printing produces robust and vibrant prints, but they may eventually crack or peel due to the ink resting atop the fabric.
Sublimation vs Heat Transfer Printing
Heat transfer printing involves transferring a design onto a substrate using heat and pressure. This process can be as simple as iron-on transfers or more advanced, like heat transfer vinyl. The design is printed onto heat transfer paper and then pressed onto the material.
Quality and Versatility
Both methods can yield vibrant, high-quality prints, but sublimation stands out for its ability to embed the ink directly into the material, resulting in a more integrated finish. This makes it ideal for complex, multicolour images. Heat transfer, while adaptable to various substrates, often produces a distinct layer atop the material.
Cost Efficiency
Sublimation provides consistent cost-effectiveness, regardless of design complexity. In contrast, heat transfer printing costs can vary, especially for designs requiring multiple colours or layers. Thus, sublimation is a more cost-effective solution for intricate, colourful designs in smaller batches.
Material Limitations
Sublimation is limited to polyester and polymer-coated materials, while heat transfer printing is compatible with various materials, including cotton, polyester, and nylon.
Durability
Heat transfer prints may initially be vibrant, but they are susceptible to wear and tear, such as cracking or peeling, especially after multiple washes. Sublimation, on the other hand, is the preferred method for long-lasting prints.
Sublimation vs Direct-to-Garment (DTG) Printing
DTG printing uses inkjet technology to apply detailed, vibrant designs onto various materials. It is versatile and can handle intricate, full-colour images on different fabric colours, including darker shades.
Quality and Versatility
While sublimation is known for producing high-quality prints, DTG printing takes it a step further. DTG excels in reproducing intricate, multicoloured designs and offers exceptional resolution and colour fidelity. It is also more versatile in terms of materials, handling cotton, blends, and some non-textile materials, unlike sublimation, which is mostly limited to polyester and similar fabrics.
Cost Efficiency
DTG printing is cost-effective for small to medium-sized orders, especially those with complex designs. In contrast, sublimation may incur higher costs for extensive print areas. DTG ensures consistent pricing, regardless of design complexity.
Material Limitations
DTG printing can print on a broader range of materials than sublimation, making it a superior choice for businesses looking to diversify their product lines beyond just apparel.
Durability
DTG prints, with proper care, rival the durability of sublimation. The inks used in DTG penetrate deeply into fabrics, ensuring the designs resist fading over time.
