About- Sublimation
Sublimation is the process of dying the substrate therefore your image is permanently IN the substrate, there is no cracking or peeling to worry about.
Sublimation does NOT use white ink therefore any white in the design will end up being the color of your substrate (ie: if you are using a ash gray shirt and the design has white clouds with a black outline, the clouds will be ash gray- the shirt color- with the black outline.)
