Sublimation printer
2020-05-20
The principle of Thermal Dye Sublimation Printer is to set four colors (cyan, magenta, yellow and black, abbreviated as CMYK) of solid pigment (called color roll) on a drum mounted on this drum. There are tens of thousands of semiconductor heating elements. When the temperature of these heating elements rises to a certain degree, the solid pigment can be directly converted into a gaseous state (a process in which the solid state is changed into a gaseous state without liquefaction is called sublimation. Therefore, such a printer It is called a dye-sublimation printer) and then jets the gas onto the print media. Each semiconductor heating element can adjust 256 kinds of temperature, so as to adjust the proportion of color and shade, to achieve a true color photo effect of continuous tone. In several types of thermal conversion printers, the output of the thermal sublimation printer is the best, but its disadvantage is that the printing speed is rather slow, and the printing medium requires high, which directly leads to the increase of the printing cost.
