Dye Sublimation printing

All of our inkjet sublimation is done on white fabric (substrates is the technical term). The reason for this is because the inks are actually transparent, when sublimated, and need a background to show up. White is the ideal background because it does not clash with the colors. Indeed, the white background actually enhances the colors. This allows printing a wide gamut of vibrant, brilliant colors on multiple substrates.

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. We use a 3M Scotchprint 2000 for this process. This is called dye sub transfer. The dye sub transfer and sublimatable fabric are then placed into an Astex heat press. When the heating cycle is completed, the image on the paper has been transferred to the item and has actually become part of the surface. Run your fingers across the surface of sublimation and you will feel nothing. The reason for this is that sublimation is always done on a polyester coated item. At high temperatures, the solid dyes in the print converts into a gas without ever becoming a liquid. When the item is removed from the heat press, the temperature drops, the pores close and the gas reverts to a solid state. It has now become part of the fabric; it cannot be washed out or come off, unless the actual fibers or coating is damaged.

Dye sublimation simply put solid dye particles being changed into gas using heat and pressure, which then bond with any Polymers present, and then change back into a solid. This equates to putting sublimation ink on paper and applying heat and pressure.

Dye : To impregnate color into a material
Sublimation: A change directly from a solid to a gaseous state without becoming liquid.
