creating and applying letters on a T-shirt or jersey is almost the same process as making vinyl graphics. Almost. Before you send a design job from your vector software to a vinyl cutter, the file must be reversed so that it’s a mirror image of the original design.
Think of it as upside-down vinyl. When you load the media on your plotter, the liner is facing upward. When you plot the film, you are cutting the bottom of the face film, not the top. Because of this, you’ll have to flip your design before you send it to the plotter. You can check this link www.thevinylrepository.com/ to get to know more about heat transfer vinyl.
Most t-shirt transfer films have only a single liner, but there are a few that have an additional liner (usually pink) to protect the film during transit. With these products, you have to cut away a section of that extra liner before you begin plotting or cutting the job.
Once you’ve cut your graphic, weed it just as you would normal vinyl. Once it’s weeded, you’ll have the clear liner showing the graphic on the bottom. Place the weeded graphic on the garment on your heat-press.
