What is Dye Sublimation?
Dye Sublimation
In order to bring out the vivid color and design, Dye Sublimation uses heat transfer to apply an image to the intended substrate. It feels smooth when you touch the keycap. As colors are embedded in the substrate, images won't fade or crack after years of excessive usage.
Proess
Dye Sublimation uses high heat to turn a printed legend from a solid into a gas and be absorbed into the material of the keycap. This method is mainly used for PBT keycaps, legends cannot be felt when the user types. It can only be used with a darker legend on a lighter base.
