How Dye Sublimation Printers Work

 In the early days of the popularity of digital cameras, people were more accustomed to keeping photos on the computer, and the value of existence was shrinking. Today, typing out photos has become a new trend.

Now, dye-sublimation printers have become the choice of most people. So, what are the working principles and characteristics of the sublimation printer?

Thermal Dye Sublimation printers work by setting solid pigments (called color rolls) of four colors (cyan, magenta, yellow and black, or CMYK for short) on a drum, which is mounted on top of There are tens of thousands of semiconductor heating elements, and when the temperature of these heating elements rises to a certain level, the solid pigment can be directly converted into a gaseous state (the process of turning a solid state into a gaseous state without liquefaction is called sublimation, so this printer Known as a dye-sublimation printer), which then sprays gas onto the print medium.

Each semiconductor heating element can be adjusted to 256 temperatures, allowing the ratio and shading of colors to be adjusted for true-color photos with continuous tone.

How Dye Sublimation Printers Work:

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 there can be a maximum of 256 levels. Because the pigments are vapor-applied to the paper through a sublimation process, the three primary colors fuse with each other to form a continuous gradation, which is much better than inkjet-printed droplets.

As far as the printing effect is concerned, the color sublimation printer can be said to be the best partner for digital cameras. Therefore, this type of printer is often called a color digital photo printer, which is especially suitable for the delicate and 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 what we call the three primary colors every day. Any other color can be combined with these three primary colors. The dye-sublimation printer realizes a variety of colors and color depths through the combination of the three colors. However, in the sublimation printing process, the three colors are not printed at the same time, but one color is used at a time, and the required color requirements are combined through three printings.

It is also 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 dye-sublimation printer relatively slow, but the high photo printing quality is enough to make up for this shortcoming.

Some dye-sublimation printers also have a film attachment process after three colorings. That is to say, the special material on the ribbon is sublimated and attached to the paper surface on the three-layer color to form a protective film, which can play the role of anti-oxidative discoloration, waterproof, anti-fingerprint and so on.

This is something that inkjet printers cannot do. The ribbon of the dye sublimation printer is for one-time use. The ribbon is generally sold together with the printing paper. Each roll of the ribbon has three colors yellow, red and blue. ribbon. So although the dye-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.
