What is a sublimation printer

The working principle of Thermal Dye Sublimation printer is to set solid pigments (called color rolls) of four colors (cyan, magenta, yellow and black, referred to as CMYK) on a drum, and install it on the drum. There are tens of thousands of semiconductor heating elements. When the temperature of these heating elements rises to a certain level, solid pigments can be directly converted into gaseous state (the process of solid state becoming gaseous without liquefaction is called sublimation, so this printer It is called a sublimation printer), and then sprays the gas onto the printing medium. Each semiconductor heating element can be adjusted to 256 kinds of temperature, which can adjust the color ratio and intensity, to achieve continuous tone true color photo effect.
