Overview Of Sublimation Process
The sublimation process is a popular technique for transferring images, designs, and text onto various materials. Dye sublimation utilizes heat and pressure to create high-quality, vibrant prints resistant to fading and cracking over time.
You’ll use sublimation ink and a printer to print your design onto sublimation paper. The design is then transferred to the desired material using a heat press.
The heat press applies heat and pressure, causing the dye to transform from solid to gaseous, bonding it with the material.
Here are some critical components of the sublimation process:
- Sublimation ink: Specialized ink designed for dye sublimation printing. It contains dyes that can turn from solid to gas when heated.
- Sublimation printer: A printer designed to handle sublimation ink ensures high-quality prints.
- Sublimation paper: A particular type of paper used to print the design. The ink will not soak into the paper but stay on the surface, allowing a smooth transfer onto the material.
- Heat press: A device that applies heat and pressure to transfer the design from the sublimation paper to the desired material. The heat press should be set to the correct temperature and pressure for the specific material type.
Keep in mind that not all materials are suitable for sublimation. Choose materials with a high percentage of polyester fibers for the best results.
Natural fibers like cotton and rayon have limitations, as they can’t fully bond with the sublimation ink, reducing the print’s durability and vibrancy. However, blending these fabrics with polyester can yield better results.
Approach To Sublimation On Different Fabrics
When considering sublimation on various fabrics, it’s crucial to understand the properties and limitations of each fabric type. With some fabrics, sublimation is best suited for specific blends or substrates.
Polyester is the most common fabric used for sublimation printing. This is due to its unique ability to absorb the sublimation ink and give a vibrant, long-lasting print. 100% polyester and blends with high polyester content work well for sublimation.
For cotton fabrics, sublimation could be more effective. Cotton fibers lack the composition to adequately absorb the sublimation ink, resulting in dull and faded images. However, specific polyester coatings are available to aid in the sublimation process on cotton.
For blends, fabric with a mixed composition, such as 25% rayon and 75% polyester, can be used for sublimation. High poly content in the fabric blend is essential for successful sublimation results.
Pure rayon fabric isn’t suitable for sublimation due to its smooth and silky texture, which is prone to scorch or melt during heat transfer. However, you can sublimate on polymer-blended rayon fabrics containing at least 40-50% polyester.
Different substrates may be required for silk, leather, or canvas fabrics. Some alternatives include using heat transfer vinyl or direct-to-garment printing.
