What is the Difference Between Sublimation and Heat Transfer?

Sublimation and heat transfer are two different methods used for printing designs onto garments or other surfaces. Here are the main differences between the two:

1. Science and process: Sublimation printing involves a process where heated ink turns from a solid to a gas and embeds itself into the fabric, becoming a permanent part of the material with no added layer on top. Heat transfer printing, on the other hand, uses a type of paper that transfers a printed design to a garment when pressed with a heat press. The design remains on top of the garment, creating a layer that can be felt.
2. Fabric and material compatibility: Sublimation printing can only be used on polyester garments or objects with a poly-coating, such as mugs, jewelry, or coasters. Heat transfer printing can be used on various fabrics, including cotton, but the print may not be as vibrant or durable as sublimation prints.
3. Durability and feel: Sublimation prints are highly durable and can last as long as the garment itself under regular use. Heat transfer prints may crack or fade with multiple washes, and the layer on top can be felt.
4. Print quality and colors: Sublimation printing allows for full-color prints, making it suitable for photos or intricate designs. Heat transfer printing may not produce photo-quality transfers as well as sublimation, depending on the type of heat transfer paper used.
5. Start-up cost: Sublimation printing tends to have a higher start-up cost compared to heat transfer printing.

In summary, sublimation printing is better suited for polyester garments and offers superior durability and print quality, while heat transfer printing is more versatile in terms of fabric compatibility but has a less durable and less vibrant print result. The choice between the two methods depends on your specific needs and preferences.

Comparative Table: Sublimation vs Heat Transfer

Here is a table comparing the differences between sublimation and heat transfer printing methods:

Sublimation printing is known for its vibrant and permanent designs on polyester or poly-coated items, while heat transfer printing is more versatile and can be used on various materials, including cotton. The choice between the two methods depends on your specific needs, project requirements, and budget.
