Dye sublimation is a process that allows manufacturers to print graphics and text in black and white or colour on a variety of items including mugs, shirts, number plates, ceramics and more. Special ink called sublimation ink, heat and pressure are used to transfer images from specially coated paper onto the variety of treated surfaces. Sublimation ink is used because it transforms from a solid to a gas without going through liquid form, enabling a clean and precise transfer. Sublimation can be done easily over the most common material -- polyester- or cotton-blend T-shirts -- easily and quickly.
Load dye sublimation ink into an inkjet printer. Load the design you want to transfer to a polymer-coated material or at least 50 per cent polyester content T-shirt into a graphics program on your computer.
Place a piece of white dye sub dark polyurethane transfer paper into your printer and print the design onto the paper.
Place the printed piece of dye sub dark polyurethane transfer paper face down onto the T-shirt or other item to which you want to transfer it.
Adhere the transfer paper with design to the dark T-shirt or other item with a heat press set to 200 degrees Celsius. Hold the press closed with moderate to heavy pressure for 10 seconds to 4 minutes, depending on the type of material to which you are transferring the design (Reference 3 contains a material-specific chart with press times and temperatures).
Remove the item from the press, examine it for colour transfer and allow it to cool.
