large format dye sublimation printing,sublimation paper with inkjet printer,dye sublimation transfer paper sheets

Most of the clothes with beautiful colors and rich colors are polyester fabrics. Most of the polyester printing is printed on the heat transfer paper by heat sublimation ink, and then the patterns on the heat transfer paper are directly processed on the polyester fabrics by the transfer machine in the form of high temperature sublimation. Of course, some of them are printed on the polyester fabrics by adding a layer of special paste on the polyester fabrics, and then directly spraying the printing patterns on the fabrics with paint ink.

Thermal sublimation is a kind of printing and printing technology, mainly through heating to make its pigment molecules into the medium, so as to realize the adhesion and printing of pigments. There are three ways to realize thermal sublimation: thermal printer, thermal sublimation transfer paper and thermal sublimation ink.

Heat rise printer

The working principle of the heat rise printer is to set solid pigments (called color rolls) of four colors (cyan, magenta, yellow and black, referred to as CMYK) on a drum, on which tens of thousands of semiconductor heating elements are installed. When the temperature of these heating elements rises to a certain degree, The solid pigment can be directly converted into a gaseous state (the process of turning a solid into a gaseous state without liquefaction is called sublimation, so this printer is called a thermal sublimation printer), and then the gas is sprayed onto the printing medium.

Each semiconductor heating element can adjust 256 kinds of temperatures, so as to adjust the proportion and intensity of colors, and realize the effect of continuous tone true color photos.

Thermal sublimation technology uses thermal energy to transfer pigments to the printing medium. The intensity of each color is controlled by the temperature change of the print head. Z can have 256 levels. Because the pigment is applied to the paper through the sublimation process, the fusion of the three primary colors can form a continuous color scale, which is much better than the ink drop effect of inkjet printing. As far as the printing effect is concerned, the color thermal sublimation printer can be said to be the z-best partner of digital cameras. Therefore, this printer is often called a color digital photo printer, which is particularly suitable for the delicate skin texture of portraits when printing. It also has the characteristics of long-term preservation and not easy to fade.

Characteristics of thermal sublimation printing technology

The special ribbon for thermal sublimation technology contains a unique protective film, which can achieve the performance of continuous color scale. Compared with the ink-jet half color scale, thermal sublimation technology is a printing technology that truly achieves the photo quality; Heat sublimation, vivid color, distinct layers, can involve details to show the difference of adjacent subtle colors; In the aspect of photo preservation, due to the protective layer, thermal sublimation has greater advantages than other printing technologies in the performance of waterproof, anti ultraviolet and anti fingerprint.
