Why sublimation printer instead of inkjet printer

The difference between Epson sublimation printer and inkjet printing is actually the same, mainly because of their different inkjet printing methods. In addition to the difference between the two, there are some reasons to persuade you why dye sublimation printers instead of inkjet printers.

Dye-sublimation printers, such as Epson wide format dye sublimation printers, use voltage to control printing in inkjet printing;

The printing inkjet method of ordinary inkjet printers is controlled by heating temperature. Dye-sublimation printers use dye-sublimation ink, and ink-jet printing with voltage control will not change the properties of the dye-sublimation ink.

Reasons to invest in sublimation printers instead of inkjet printers

Dye sublimation is a very special development technology. It 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 it can have a maximum of 256 levels. Because the pigment is applied to the paper in the gas phase through the sublimation process, the three primary colors can merge with each other to form a continuous color gradation. The composite color gradation can reach 24bit, and the total can reach 16 million colors, compared with inkjet printers. more realistic.

Yellow, red, and blue are the three primary colors we call daily. 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.

During the printing process, the printing medium needs to pass through the printer 3 times in total, which also makes the printing process of the dye sublimation printer relatively slow. After three times of coloring, there is a filming process. That is, the special material on the ribbon is sublimated on the three-layer color and attached to the paper surface to form a protective film, which can make the color more bright and vivid, and has the ability to waterproof and anti-oxidize, which greatly extends The preservation time of photos is something that inkjet printers cannot do.

Since the color sublimation printer does not have the problem of ink droplet diffusion, it can achieve very good resolution. Its resolution of 300×300dpi is comparable to the printing accuracy of inkjet printers 4800×4800dpi, while the popular digital ones on the market The output resolution of the developing machine is mostly 320dpi, so the output photo effect of the sublimation printer is very close to that of the developed one.

What is the width of Epson sublimation printer?

It is smaller than the size of A4 (210mm×297mm) because there should be a blank border around the paper, generally 5mm should be left on the side. The maximum size of the printed photo is 20 cm wide and 29 cm long.
