It’s the chemistry behind dye sublimation that makes it the correct technique for printing on polyester and polyester resin coated products. Using a wide-format inkjet printer, dye-sub inks are printed on a special transfer paper. From there, the ink is heat transferred from the paper onto a fabric by using a heat press. The ink changes from a solid to a gas (hence the term “sublimation”) and enters the polyester fibers. The polymers in the polyester bond when heated, which allows the graphics to quickly become permanently embedded into your materials. As a heated gas, the ink becomes fully infused into the fabric instead of just printed on the surface, resulting in long-lasting, high-quality products. An inkjet printer uses only as much ink as needed to produce an image or a printed page; ink remaining from one print batch will be used on subsequent ones. The dye sublimation process is less efficient in terms of ink: the printer transfers only a portion of each of the ribbon's three primary color panels to the page. Sublimation items must have a white or light-coloured print area. Black or dark-coloured surfaces can't be sublimated. The item may lose colour over the months due to the effect of UV rays if it's permanently exposed to direct sunlight. Like all inkjet printers, the printheads may clog if they are not used frequently.

Dye-sublimation printers are relatively convenient for us. So, how are Dye-sublimation printers made? Let's take a look together next.

Principle of Dye Sublimation printer

Dye sublimation technology uses heat energy to transfer pigments to the printing medium. The intensity of each color is controlled by the temperature change of the print head, and the maximum can have 256 levels. Because the pigment is applied to the paper in the gas phase through the sublimation process, the fusion of the three primary colors can form a continuous color gradation, which is much better than the ink droplet effect of inkjet printing. In terms of printing effect alone, the color sublimation printer can be said to be the best partner of digital cameras. Therefore, this kind of printer is often called a color digital photo printer, which is especially suitable for the delicate skin texture of portraits when printing. It also has the characteristics of long-term preservation and not easy to fade. Magenta, yellow, and cyan are the three primary colors we call every day. Any other color can be combined with these three primary colors. Dye-sublimation printers achieve multiple colors and color depths through the combination of three colors. However, in the dye-sublimation printing process, the three colors are not printed at the same time, but one color is used each time, and the required color requirements are combined through three printings. It is for this reason that the printing medium needs to pass through the printer 3 times during the printing process, which also makes the printing process of the sublimation printer relatively slow, but the high photo printing quality is enough to make up for this shortcoming. Some Dye-sublimation printers have a film attaching process after three colors. That is, the special materials on the ribbon are sublimated on the three-layer color and attached to the paper surface to form a protective film, which can prevent oxidation and discoloration, waterproof, and anti-fingerprints. This is something that inkjet printers cannot do. The ribbon of the Dye-sublimation printer is disposable, and the ribbon is usually sold together with the printing paper. Each roll of the ribbon has three colors of yellow, red, and blue as a set, and each photo is printed. ribbon. Therefore, although the sublimation printer can also print at low resolution, the printing cost cannot be reduced, and the printing speed can only be slightly increased. It is recommended to always print at the highest resolution.

Precautions

By the way, I would like to remind you that after the Dye-sublimation printer is printed, the printed images and text will leave a latent image on the used ribbon. If the content printed by the Dye-sublimation printer is confidential, it is recommended to save the ribbon and use it up. After destruction. Dye-sublimation printer resolution is also called output resolution, which refers to the maximum number of dots per inch that can be printed in both the horizontal and vertical directions when the Dye-sublimation printer prints out, usually in the form of "dot per inch" or dpi (dot per inch) Said. The so-called maximum resolution refers to the maximum resolution that the Dye-sublimation printer can print, that is, the so-called limit resolution of the print output. The printer resolution usually refers to the maximum resolution of the Dye-sublimation printer, and the resolution of the Dye-sublimation printer is generally around 300×300dpi.
