What is Sublimation Printing: Complete Guide

August 28, 2025

Sublimation printing is widely used to produce vivid, enduring images on clothing, apparel, merchandise, and gifts. From printed t-shirts and sweatshirts to mugs and all-over printed phone cases, sublimation delivers crisp results not achievable with other methods.

What is Sublimation Printing?

Sublimation printing uses heat to transfer special ink onto materials. As the ink heats, it becomes a gas and bonds with the material’s fibers. Unlike standard printing, where ink rests on top of fabric, sublimation embeds the image within. This allows for lasting, soft-touch, highly detailed prints.

How Sublimation Printing Works

The sublimation process is straightforward but requires precision at each step:

Design Development: Create designs digitally by using appropriate graphic tools.
Printing: The designs are printed on sublimation transfer paper with sublimation ink.
Transfer: The printed transfer paper is placed on the material selected for the project and then placed in a heat press for a predetermined amount of time (usually 15-30 seconds). This time serves to heat both the paper and the material while the sublimation ink turns to gas.
Material Bonding: The sublimation ink gas penetrates the fabric or coating as the sublimation paper is pulled away to reveal the printing design that will be there forever. The sublimation print is now permanent and bonded to the transfer material.

This process produces prints that have more detail and color, while sublimation printing adds softness so that it feels like the design is now part of the fabric rather than sitting on top of the material.

What materials are suitable for Sublimation Printing?

Sublimation printing will not work on every material; however, results are best on the following types of materials based on sublimation printing:

Polyester and Polyester Blends: Images and graphics printed with sublimation are bright and vibrant on polyester and polyester blend t-shirts, sweatshirts, cold-weather style polos, sportswear, and other activewear.

Polymer-Coated Items: Items like mugs, phone cases, mouse pads, and other types of promotional products.

White or Light-Colored Surfaces: Bright images usually are going to be best if the selected surfaces are light-colored or, better yet, white surfaces.

Benefits of Sublimation Printing

Bright and Lasting Colors: Sublimation printing produces a bright product that will resist fading and remain bright through many washings.
Soft and Smooth Finish: The ink embeds into the fabric, leaving no raised surface. When you touch it, you feel the fabric, not the print.
Full coverage printing: The design can cover the entire item, including the edges and seams of the product. Unlimited creativity and graphic complexity can be considered in order.
Durable: A sublimated print will not crack, peel, or fade and is therefore great for sports uniforms, work uniforms, and promotional wear.
Photo Quality Printing: High-resolution images, gradients, and very fine details print very well and maintain their clarity through the sublimating process.
Fast and Efficient: Especially useful if you have a small to medium batch of customized merchandise, gifts, or limited editions of apparel.
More environmentally friendly: Using water-based inks and only creating minimal waste compared to some traditional printing methods.

Limitations of Sublimation Printing

Despite its advantages, sublimation printing does have limitations:

Limited Fabric Choices: Works best on polyester or polymer-coated fabrics, and not cotton
Not Great for Dark Surfaces: Colors will look more dull and work better when a white base is printed.
Cost of Equipment: Sublimation printers, inks, and heat presses are expensive to purchase but are needed to make high-quality prints.
Size Limitations: The size of the design is limited to the size of the transfer paper and the heat press.

Uses of Sublimation Printing

One of the key benefits of sublimation printing is the versatility it provides across various mediums and products.

Custom Apparel: Sublimation printing is used to design personalized t-shirts, jerseys, and other custom apparel, such as sportswear and team uniforms. With sublimation printing, you can design an entire surface, and the design will be there forever and will never crack or peel.

Home Textiles: Sublimation printing allows for the creation of custom prints on pillow covers, curtains, and bed sheets. Many people will wash and dry these products repeatedly, and sublimation ensures that the colors remain bright, no matter how many cycles they go through—this is why sublimation printing is popular.

Accessories: Sublimation printing can also be used to print certain accessories, like bags, caps, scarves, and more. Products can be branded for custom color schemes, logos, patterns, or designs printed with sublimation, which will create a smooth and where the print is embedded in the fabric and not printed on top.

Corporate Branding Merchandise: Most branded merchandising is done by sublimation printing, like mugs, mousepads, water bottles, etc.

For Memorable Events: Whether it's a wedding, birthday, or sports event, sublimation printing has the ability to create unique value and products for memorable events.

Promotional Products: Sublimation lets businesses create visually stunning designs on a variety of products made from different materials, making it easier to stand out from the competition.

Gifts: Personalize their gifts by using sublimation to make laser-engraved products. Gifts include products such as t-shirts, mugs, and keychains, to name a few. This enables businesses to include personalized names, photographs, and custom artwork on their gifts.
