The Future Development Prospect of Sublimation Printing

Sublimation is mainly through heating to make the pigment molecules into the medium. Dye sublimation, with vivid colors and distinct layers, can involve details to show the difference between adjacent subtle colors; its special ribbon contains a unique protective film, which can achieve the performance of continuous color gradation, which is better than inkjet half gradation.

In other words, dye-sublimation technology is a printing technology that truly achieves photo quality; in terms of photo preservation, because of its protective layer, dye-sublimation has a greater advantage than other printing technologies in terms of water resistance, UV resistance and fingerprint resistance.

Features of Dye Sublimation Printing

In the application of sublimation printing, for example, images such as portraits, landscapes, texts, etc. are printed on the inkjet paper for sublimation transfer in a mirror image mode using an inkjet printer equipped with sublimation transfer ink, and then passed through the thermal transfer equipment. Heating to about 200 ℃, sublimation of the thermal transfer ink on the sublimation paper into the substrate, so that the color image on the paper is realistically transferred to the textile.

In addition, thermal sublimation ink is also known as thermal transfer ink. Low-energy, easy-to-sublime disperse dyes are made into digital printing inks, which are printed on transfer paper. By heating, images can be made in the shortest time. Chemical fiber fabrics and other materials, it is very suitable for the market needs of personalized development and the requirements of environmental protection.

Applications of Dye Sublimation Printing

At present, the domestic sublimation market is still very wide, such as the application of sublimation printing on light box cloth. At the same time, sublimation printing is currently the most environmentally friendly printing and dyeing method. In recent years, sublimation has developed very rapidly in Europe and the United States. The development of sublimation is as promising as the development of thermal transfer printing.

Advantages of Dye Sublimation:

1. Thermal sublimation is a very special developing technology. Different pigments are directly applied to the paper during the sublimation process. In addition, the intensity of each color is controlled by the temperature change of the print head, and the maximum level can be 256. So more realistic than inkjet printers.

1. In the process of sublimation printing, each color is not printed at the same time, only one color can be printed at a time, which is combined by three printings, so as to achieve the required color requirements.

Then there is the film attached, which can make the color of the photo bright, with the ability of waterproof and anti-oxidation, and greatly prolong the storage time of the photo, which is also impossible for inkjet printers.

1. There is no problem with ink droplet spreading. In terms of definition, it can reach the standard, and its resolution of 300 × 300dpi can be compared with the printing accuracy of 4800 × 4800dpi of inkjet printers.

In general, the output resolution of the popular digital processing and expansion machines on the market is mostly 320dpi, so the output photo effect of the thermal sublimation printer is very close to that of the developed ones.

As for the disadvantages, the dye-sublimation printer uses temperature control, it can only print one primary color at a time (of course, if you print monochrome then there is no problem), so in terms of speed, the printing speed of the dye-sublimation printer is relatively slow.

In addition, dye-sublimation printers are particularly sensitive to dust, and the working temperature is particularly high, especially when printing continuously, it will also have a certain smell.
