Sublimation printing, also known as dye-sublimation, is the process where the usage of sublimation paper + sublimation ink is used together to sublimate / transfer the ink onto the substrates / products at a high temperature. The design is permanent and does not fade or peel off with time.
You may be wondering how sublimation printing works. First, you print the desired image on a sublimation transfer paper using sublimation ink and printer. Then, the transfer paper and the substrate go through the heat press. Here, they are exposed to around 350-375 degrees Fahrenheit / 175 - 190 degrees Celsius.
The heat press allows the sublimation ink and transfer paper to turn into a gaseous state. When they are in this state, they can seep through the substrate’s material. This is possible as the heat both releases the sublimation ink’s gas and opens the pores of the substrate.
Once you remove the transfer paper and the substrate from the heat press, sublimation printing happens. The ink that seeped through the substrate’s material solidifies. Then the substrate’s pores close permanently, thereby holding the ink in place. The printed image won’t fade by itself, and can last for many years.
Silkscreen printing is a printing technique whereby a mesh is used to transfer ink onto the product(such as t-shirt etc). The ink stays on the t-shirts for many years, they are very lasting and durable, and this method is use for mass production instead of printing just 1 or 2 products, as this printing method need a template/mould (a printed mesh with the design is needed).
