Sublimation uses high heat and solid dyes to produce photo lab-quality images. Dye-Sublimation
printers contain a roll of transparent film made up of page-sized panels of colour. Solid dyes
in cyan, magenta, yellow, and black are embedded in the film. Print head heating elements vaporize
the inks, which adhere to a specially coated substrate. As the ink cools it re-solidifies on the
Dye-Sublimation printers lay down colour in continuous tones one colour at a time, instead of
dots of ink. Because the colour is absorbed into the substrate rather than sitting on the
surface, the output is more photo-realistic, more durable and less vulnerable to fading than
other ink technologies.
