Dye Sublimation Printing Process

Date:Aug 18, 2016

The dye-sublimation printing process is used to print on polyester or other synthetic fabrics. The latest innovation involves the creation of fabric made from recycled water and soda bottles (PET), which is a type of polyester.It is used for applications such as T-shirts, banners, table covers, id cards,rtswear and flags. The original printers were an electrostatic technology using toners but now are generally large format inkjet printers using specially formulated inks. The dye sublimation inks are a disperse dye suspended in a liquid solvent, like water. The images are initially printed on coated heat-resistant transfer paper as a reverse image of the final design, which is then transferred onto polyester fabric in a heat press operating at a temperature around 180 to 210 C (375 F). Under high temperature and pressure, the dye turns into a gas and permeates the fabric and then solidifies into its fibers. The fabric is permanently dyed so it can be washed without damaging the quality of the image.
