Thermal Imaging Digital Printing Technology Details Interpretation (3)

3) Slow printing

Because the dye-sublimation printer is a three-primary cycle printing, each time a color is printed, the paper has to go one way back and forth in the print path, so a print job needs to go three times. Therefore, the efficiency of dye-sublimation printers is much slower than ink-jet printers. The speed of traditional color inkjet printers is nearly three times faster than sublimation printers, and sublimation printers cannot increase printing speed by reducing the print resolution. This makes sublimation printers unsuitable for applications that often require continuous printing, hindering it from achieving greater development in the commercial arena.

4) Not suitable for text printing

Since the dye-sublimation printer prints text, it mixes the four solid colors including black and prints together. Therefore, the purity of the black color is very low and cannot be compared with ink jet, so it is not suitable for text printing. the use of.

5) The print format is narrow

At present, most common sublimation printers only have a 4×6 inch output capacity, which is just the size of an ordinary photo. Compared with inkjet A4 or even A3 format, the sublimation printer still has a big gap, but is slightly larger. The format of the thermal sublimation printer is not only expensive for the machine itself, but also very expensive for consumables, which is not suitable for public users.

6) The use of the environment is very high

Thermal sublimation printers are sensitive to dust. If dust enters the print head or ribbon, the print quality is likely to have a serious effect, such as the formation of a long thin white line, causing the entire photo to be scrapped. In addition, the thermal sublimation printer also has a high temperature requirement for the work. If it is continuously operated for a long time, the color accuracy may be affected due to poor heat dissipation.
