Sublimation Printing Technology is More and More Popular in Our Daily Life

     Sublimation printing is by far the most commonly used method of modern textile printing. It is quick, reliable and environment friendly, allowing print companies to cut down on waste and speed up repeatable processes without any loss of quality. In point of fact, sublimation printing is normally more reliable for fixation than older styles of textile printing due tothe science acting on the fibres during the printing process.The process is dye sublimation printing. It involves the application of sublimation inks on any polyester/polyester coated surface making use of a heat press for providing the necessary combination of time, heat and pressure. Using the combination the ink is converted from a solid state to a gaseous one and allows them to break through sublimation for forming a permanent and full color image.
     Dye sublimation was discovered by Noel de Plasse, a Frenchman, in the 1950s. De Plasse noted that high temperatures could cause specific dyes to sublimate - that is, to become an integral part of the paper on which they are printed. Dye sublimation printers, which are an offshoot of de Plasse's original process (the sublimation printer uses an electrical charge to achieve the same effect) effectively inject the ink into the paper - which means no bleeding, no loss of colour and no fading.

    For a long period, the sublimation printers were used as specialist devices for the purpose of photographic applications and demanding graphic arts. With the arrival of digital photography the technology of sublimation printing was brought to focus. Photos printed using dye sublimation are not subjected to the problems that inkjet photographs have. An inkjet photograph, for example, will run if it is exposed to water. Any photograph printed using dye sublimation is protected by the clear layer, which means no running once the ink has dried.
