Dye Sublimation Printing -------------------------------------------------------------------------------- If you need personalized mugs, license plates, or other hard surface items such as signs or plaques, then Dye Sublimation is the answer! Can also be imprinted onto white Hanes Soft L'ink™ 50% 50% poly/cotton tee shirts. Photographic quality images along with any artwork and graphics can be imprinted onto sublimatable surfaces.
Dye Sublimation, as a process is really very simple. It is the method of applying an image (photograph or any image) to specially coated ceramics, metals and polyester cloth, using three main ingredients: sublimation ink, heat and pressure.
Sublimation ink is unique in its ability to convert from a solid to a gas without going through a liquid form. (Just like dry ice.) The conversion is initiated by heat and controlled with pressure and time. Hard items such as ceramic, fiber board, metals, etc. requires a special coating to accept the sublimation inks. You must purchase the mugs, tiles, metals, etc. with the coating already on them, it is not something you can coat yourself. We purchase from the Unisub ™ line of sublimatable blanks, which you can order through our company. Apply to 100% polyester (ie: mouse pads and puzzles) you do not need any coating, if is applied directly to the 100% polyester fabric.
The actual process of sublimation involves placing a sublimation transfer that has been printed on paper onto polyester or polymer-coated material and then applying heat (usually with a flatbed heat press) to both. The heat changes the solid print on the paper into a gas, which then prints into the polymer surface
The operative word here is into. In addition to the heat causing the sublimation process, it also opens up the polymer so the gas actually goes into the surface coating. Seconds after the surface starts to cool, the gas reverts back to a solid and the polymer closes back up, trapping the solid. This is why you can run your finger across the surface of a sublimated metal plate and you will not feel anything.
The two most common methods used to produce printed transfers is with an inkjet printer or a single color desktop laser printer. Either one requires the special sublimation cartridges used to produce heat transfers.
