How The Large Sublimation Printer Works

The Sublimation technology of Large Sublimation Printer uses heat energy to transfer pigment to the printing medium. The intensity of each color is controlled by the temperature change of the printing head, and the maximum sublimation printer can have 256 grades. Because the pigment is applied to the paper through the gas phase of the sublimation process, the three primary colors can be combined to form a continuous color level, which is much better than the ink droplet effect of inkjet printing. In terms of print effect alone, color thermosublimation printers are the best partner for digital cameras,
Therefore, this kind of Large Sublimation Printer is often called color digital photo printer, which is especially suitable for the exquisite skin texture requirements of portrait when printing, and also has the characteristics of long-term preservation and non-fading. Magenta, yellow, cyan, which is what we call the three primary colors in our daily life. Any other colors can be blended through these three primary colors. The thermal sublimation printer is to achieve a variety of colors and color depth through the collocation of three colors. In the process of non-superheated sublimation printing, three colors are not printed at the same time, but one color is used at a time, through three times of printing combination into the desired color requirements. It is also for this reason that the printing medium needs to go through the printer three times in the printing process, which also makes the printing process of the thermal sublimation printer relatively slow, but the high photo printing quality can make up for this defect.
Some Large Sublimation printers have a film attachment process after three times of coloring. That is, on the three layers of color, the special material on the ribbon is sublimed and attached to the paper surface to form a protective film, which can play the role of anti-oxidation discoloration, waterproof, anti-fingerprint and so on. This is something ink-jet printers can't do. The ribbon of the thermal sublimation printer is disposable, and the ribbon is generally sold together with the printing paper. Each roll of the ribbon is a group of three colors, yellow, red and blue, and each print photo is rolled over a group of ribbons. So although the thermal sublimation printer can also print at a low resolution, but the printing cost can not be reduced, can only slightly improve the printing speed, it is recommended to always print at the highest resolution.
