A variety of methods are used to apply graphics to fabric.

Heat Transfer
Images are baked into fabric using a large vacuum. It is very exact, creating bold color separation. However, it doesn’t blend colors well.
Ink-jet printing
Produces photographic quality images on nearly any material using a computer scanner. The images are rich and detailed, but the inks have a limited outdoor life span unless top-coated.
Silkscreening/screen printing
A process that transfers graphics onto another material using special screens. Ink is spread over the top of the screen and printed on the fabric face.
Letters and forms are cut from fabric and sewn on to the base fabric. When the letters are cut out of the fabric and replaced by different-colored fabric, they are called “cut-out letters.”
Dye sublimation
The basic inkjet dye sublimation process uses a heat sensitive sublimation dye, dissolved in a liquid, to print graphics and text onto special inkjet paper. This is called a dye sub transfer. The dye sub transfer and a sublimatable item are then placed into a heat press. hen the heating cycle is completed, the image on the paper has been transferred to the fabric and has actually become a part of the surface.
