Of Dye Sublimation Printing Technology And Its Applications – Dye Sublimation – Silk Screen Printing

By | November 17, 2016

Although the dye sublimation printing technology known degree, smaller than the field office inkjet, laser two basic printing. However, its photo output, fabrics and glass body Transfer And so has a unique advantage, especially in photo printing effect, high image resolution, color transition of the natural, easy to store and other advantages, a large color digital photo-processing industry, the preferred printing method. The main reason for this is that the principle of dye-sublimation printing technology achieved a unique, and therefore below the working principle of the dye-sublimation printer for further clarification.

Printing technology using dye-sublimation photo printer

Sublimation printing technology, is the use of sublimation from the gas to solid and solid to gas without an intermediate state, the process of mutual transformation to achieve photo printing, that is, solid color printers use thermal recording head heated by direct sublimation to gas, photographic paper and then transfer to generate images. Sublimation printing using thermal sensor technology, the print will YMCO (yellow / products / green / protective film) three-color dye and a layer of protective film after evaporation followed by heat treatment in the special photographic paper imprint. Is the source of color dye ribbon, generally divided into yellow, goods, green three-plus protection film or yellow ribbon, goods, blue, black four-ribbon. Ribbon set on a drum, the drum is equipped with tens of thousands of semiconductor heating elements, heating elements constituted by the print head. When the ribbon at a certain temperature the thermal print head, the direct sublimation into gas and then sprayed into the print media on the formation of color.

Dye-sublimation printing technology As print, photo paper and ribbon with a roller at the same time, were heated under the print head using the print head diameter less than 40 m in the silicon lattice heat, dot matrix print head heating power will be painted on the dry solid ribbon melt ink. Heating process, the amazing transformation took place in about 320 degrees Fahrenheit, heat separate polymer molecules, when the print head off, the temperature drop from the gas into a solid ink, ink embedded in polymer. Polymer molecules aggregate together (this is why the dye-sublimation printing indelible reasons), when a color print after the beginning of the next automatically moved to a different color, resolution depends on the heating element, the amount of increase depends on the color decoration The temperature in the heating element, a piece of paper with sublimation ribbons produce millions of color mixture. Therefore, high-quality images available results.

Principle of sublimation printing technology Each heating head can be adjusted out of 256 high and low temperatures, then led to the degree of sublimation color, 256-class distinction, because it uses the color pigment into yellow, cyan, magenta three, can combined into the yellow color also has 256 256 256 cyan magenta = 16700000 kinds of trips are three-color effect can be achieved the performance of all 256 Levels 16.77 million continuous tone colors. Fresh color, structured, can involve subtle detail show color difference between adjacent; its special ribbon contains a unique protection film, you can achieve a continuous gradation of performance, compared with the ink-jet semi-Levels, the heat sublimation technology to achieve the photo quality is truly a printing technology; in photo preservation, since the protective layer, dye-sublimation printing technology in the water than the other, anti-UV and anti-fingerprint occupy a greater performance advantage.

Sublimation Printing Technology Working diagram Yellow, cyan, magenta and fusion of three primary colors can form a continuous color scale, while printing the same picture format, resolution less than the ink-jet printer, but print the form a continuous gradation of the print, but they can and high-end inkjet photo printers are comparable, the transition smooth natural picture colors are the main features of its print. The printing, the color dye-sublimation printer can be said that the best digital camera partner, therefore, this printer has color digital photo printer is often called, especially for fine print on the portrait demands delicate skin texture, but also not easy to fade with the characteristics of long-term preservation.

But in the process of sublimation printing, printing three colors is not the same time, but every time you use a color by three times to form the required color printing requirements. Is precisely for this reason, the print media in the printing process, a total of go through the printer three times, also dye-sublimation printer, the printing process is relatively slow, but the photo print quality high enough to compensate for this shortcoming.

Summary: dye-sublimation printing technology unique works, it’s high quality output as the biggest bright spot. Throughout the sublimation printing technology or there are some advantages and disadvantages, and they mainly: technology, dye-sublimation technology is that the printer uses ribbons, printed by heating the colored dye to the paper medium, the formation of color images. Performance, dye-sublimation technology-based applications, 300 * 300dpi resolution can be compared with 4800 4800dpi inkjet printing precision; in photo preservation, heat rise of the printer to print out the photos really achieve a permanent retention period; print speed , the output slowly. Consumables Costs, dye-sublimation printers use in product prices and costs are higher than those of office printing supplies.
