Sublimation is a type of printing process that utilizes heat to transfer dye into fabric. Colors and images are dye-sublimated onto transfer paper. The transfer paper and fabric are processed with heat and pressure to dye the fabric. It is different from screen printing in that you are dying the fabric of the shirt, rather than printing on top of it. This results in shirts where the sublimated ink can be seen, but not felt on the fabric.
 
Polyester shirts in adult, ladies and youth sizes are available.
Sublimation printing allows for detailed image printing on shirts with many coloring options.
