Thermal Dye Transfer System
Thermal dye transfer system uses its own dedicated ink ribbon and receiver paper.
The ink ribbon is coated with three basic color dye ink (yellow, magenta & cyan) on a thin polyester film.
Along with this ink ribbon, another dedicated resin-coated receiver paper is needed for fixing the transferred dye.
<Advantage of dye sublimation system>
High quality print
Compact and space-saving system
Smooth gradation print
Varying the temperature of the thermal print head optimizes the amount of dye, resulting in smooth gradation and high-definition prints. The smoothness is obvious in comparison to the inkjet print, when enlarging the print image.*
* Comparison test with inkjet print is conducted by DNP test method. Result may vary depending on printer model, consumables and print settings.
Thanks to the clear overcoat, the dye sublimation print is durable against water and friction. The overcoat also protects the image when the print is stored in plastic case.
Resistant to color fade
DNP's dye sublimation print is proven to be resistant against color fade, based on the ozone test result.*
* Test was conducted and evaluated by DNP method.
<Ozone stability test method>
The test is conducted by placing the printed material in a test chamber where the ozone concentration is set at the fixed level as follows.
Ozone gas: 1 - 10ppm
Tempreture and Humidity: 24℃ 60% R.H.
Set endpoint at the accumulated amout of exposure where the reflected optical density (O.D.) of the print decreases from 1.0 to 0.7 (30% drop).
[Print lifetime prediction method]
The integral concentration per year used in calculations of the predicted print life shall be 40 ppm • hr.
Indoor ozone stability (years) = Integral concentration (ppm • hr)/40 (ppm • hr/year)
* The predicted year of print life is based on the accelerated ozone test method that assumes long time print storage in doors, away from direct sunlight, and exposed to the air. Performance may vary depending on the storage or display condition.
