===Heat transfer vinyl (HTV)===
Another form of T-shirt decoration is [[heat transfer vinyl]], also called HTV. HTV is a polyurethane material that allows apparel designers to create unique layered designs using a specialized software program. Once the design is created, it is then cut through the material using a vinyl cutter (or Cut n Press) machine.

There are dozens of different colors available, as well as glitter, reflective, and now even unique patterns (such as mermaid skin) which come in rolls and sheets.

After the design is cut, there is a process called “weeding” whereby the areas that do not represent the design are picked away from the transfer sheet and removed so that the intended design remains. HTV is typically smooth to the touch and does not feel rubbery or stiff. The edges are typically clean-cut and produce high contrast.

Designers can also create multiple color designs, or multi-layered designs, using HTV. This process is done in the design software before the design is sent to the cutter for the different materials. A heat press is then used to apply pressure and heat to the vinyl so that the material permanently adheres to the garment. The temperature and pressure vary according to manufacturer specifications.
