     how dye sublimation works
     Dye sublimation, a dye-transfer process that got its start in the 1960s for use in textiles, has

advanced in recent years to provide wear-resistant, full-color surface decoration of flat objects like

mouse pads and tiles. Even more recently, it has proved applicable to three-dimensional products.

      When the dyes are heated in this transfer process, they vaporize, and if they are in close proximity

to a suitable substrate, such as a plastic or coating, the vapors penetrate the adjacent substrate by

around 0.002 in. up to 0.25 in.

    The plastic substrate must be able to withstand temperatures of 280 to 375 F necessary to vaporize the dye.

      Since the dyes are transparent, the substrate should be light in color—white, light gray, or beige. If the plastic substrate is translucent, it will remain translucent after coloring. The lighter the substrate color, the better the result of this process, the dyes will penetrate a black substrate but will not be visible.
      When first used in textiles, this process allowed a printer to make a design on sublimation paper and then heat transfer it to knits or weaves.For flat-surface decoration such as snowboards, the design is first printed on paper, and then a heat press impregnates the paper design into the substrate.
