sublimation dye DTF printer,sublimation printer machine price,sublimation printer machine cost

Although the familiarity of dye thermal sublimation printing technology is not as good as the two basic printing technologies in the office field: inkjet and laser. However, it has unique advantages in photo output, transfer printing of fabric and cup body, especially in the effect of photo printing, with the advantages of high image resolution, natural color transition and easy preservation, it has become the preferred printing method in many color digital photo printing industries.

Although the familiarity of dye thermal sublimation printing technology is not as good as the two basic printing technologies in the office field: inkjet and laser. However, it has unique advantages in photo output, transfer printing of fabric and cup body, especially in the effect of photo printing, with the advantages of high image resolution, natural color transition and easy preservation, it has become the preferred printing method in many color digital photo printing industries. The main reason for this is the unique principle of thermal sublimation printing technology. Therefore, the working principle of thermal sublimation printing is further explained below.

Photo printer using thermal sublimation printing technology

Thermal sublimation printing technology is to use the process of sublimation from gas state to solid state and from solid state to gas state without intermediate state to realize photo printing, that is, the solid pigment used by the printer is directly sublimated into gas phase after heating by the thermal recording head, and then transferred to the photo paper to generate images. Thermal sublimation printing uses thermal induction technology. During printing, ymco (yellow / magenta / Green / protective film) three color dye and a layer of protective film are vaporized in turn through heat treatment and then stamped on special photo paper.

The source of color dyes is color bands, which are generally divided into yellow, magenta and cyan color bands plus protective film or yellow, magenta, cyan and black color bands. The ribbon is arranged on a drum, which is provided with tens of thousands of semiconductor heating elements, which constitute the print head. At a certain temperature, when the ribbon passes through the thermal print head, it is directly sublimated into a gaseous state, and then sprayed onto the print medium to form color.

Thermal sublimation printing technology

When printing, the photo paper and the ribbon pass through a roller at the same time and are heated under the print head. The diameter on the print head is less than 40 μ M, the hot spot array on the print head is powered on to melt the dry solid ink coated on the ribbon. During the heating process, a wonderful transformation takes place. At about 320 degrees Fahrenheit, the heat separates the polymer molecules. Once the print head passes, the temperature drops, the ink changes from gaseous state to solid state, and the ink is embedded in the polymer. Polymer molecules are polymerized together (this is the reason why thermal sublimation printing cannot be erased). When a color is printed, it automatically moves to the beginning for the next color. The resolution depends on the heating element, and the amount of color decoration depends on the temperature of the heating element. The rising ribbon on a piece of photo paper produces a mixture of millions of colors. So you can get high-quality picture effect.
