What is Sublimation?
Sublimation printing is a specialized printing technique used to transfer high-quality, full-color designs onto various surfaces, primarily polyester fabrics and polymer-coated substrates. It involves the transformation of dye particles from a solid state to a gas state without going through a liquid phase, hence the term "sublimation."
The process of sublimation printing involves the following steps:
1. Design Preparation: The initial step is to create or prepare the design that will be printed. This can be done using graphic design software, and it can include images, artwork, logos, or any other desired visual elements.
2. Printing with Sublimation Ink: The design is printed onto a special transfer paper using sublimation ink. Unlike regular inkjet ink, sublimation ink is specifically formulated to convert from a solid to a gas when subjected to heat and pressure. The ink is typically applied to the paper using a sublimation printer equipped with specialized printheads.
3. Transfer Process: The printed transfer paper is then placed on the substrate to which the design will be transferred. The substrate is usually a polyester fabric or a polymer-coated surface, such as mugs, mousepads, or ceramic tiles. The transfer paper is positioned with the printed side facing the substrate.
4. Heat and Pressure Application: The transfer paper and substrate are pressed together using a heat press machine. The combination of heat and pressure causes the sublimation ink to convert into a gas. This gas then permeates the surface of the substrate and becomes embedded within the material's fibers or coating.
5. Cooling and Setting: After the sublimation process is complete, the heat is removed, and the substrate is allowed to cool. As it cools, the sublimated ink returns to a solid state, permanently bonding with the substrate's surface. This ensures excellent color fastness, durability, and resistance to fading or washing.
Sublimation printing offers several advantages. It allows for high-resolution, photorealistic prints with vibrant colors, smooth gradients, and intricate details. The process enables all-over printing, covering the entire fabric or substrate with the design. It also offers excellent durability because the ink becomes a part of the material rather than sitting on top of it. Moreover, sublimation printing is ideal for producing customized or personalized products and allows for quick production turnaround times.
It is important to note that sublimation printing is most effective on polyester fabrics or materials with a polymer coating. This is because the sublimation ink needs to bond with polymers for the best results. Natural fabrics, such as cotton, do not have the necessary polymer content, so sublimation printing is not suitable for them.
