Because the thermal sublimation printer uses different printing technology from laser or inkjet printer, it usually prints less than one piece per minute. What is a sublimation printer? The following is a collection of thermal sublimation printers for your reference only. Welcome to read!

What is a thermal sublimation printer

Each semiconductor heating element can adjust 256 kinds of temperatures, so as to adjust the proportion and intensity of colors, and realize the effect of continuous tone true color photos.

Precautions during printing

By the way, it should be noted that after printing, the printed image and text will leave a latent image on the used ribbon. If the printed content belongs to confidential information, it is recommended to keep the ribbon and destroy it after use. Printer resolution, also known as output resolution, refers to the maximum number of points that can be printed per inch in both horizontal and vertical directions during printing and output. It is usually expressed as "point / inch", or dpi (dot per inch). The so-called maximum resolution refers to the maximum resolution that the printer can print, that is, the limit resolution of the printout. The printer resolution usually refers to the maximum resolution of the printer. At present, the resolution of thermal sublimation printer is generally 300 × About 300dpi.

Other information

What is a thermal sublimation printer? At present, the marking speed of laser or inkjet printer products provided by all printer manufacturers for users is measured by the printing speed. However, the thermal sublimation printer uses a different printing technology from the laser or inkjet printer. Generally, it prints less than one piece per minute. Therefore, the printing speed of the thermal sublimation printer is expressed in seconds. Generally, the printing speed of the thermal sublimation printer is about 90 seconds, and the first piece takes a little longer, because the heated print head needs to be preheated. During printing, the thermal sublimation printer vaporizes the red, yellow and blue color films in turn through heat treatment and then imprints them on the special photo paper. Because the heating level of the heating device can be divided into 128 or 256 levels at present, due to the different concentration of vaporized pigments, the colors will also correspond to 128 or 256 levels of continuous color levels, which is the concept of color level. There are 128 or 256 levels of ternary colors per color, and a total of 209 can be generated. A continuous color scale of 70000 colors or 16.77 million colors, which is almost the limit of color depth that human eyes can distinguish. At present, most thermal sublimation printers use 256 color levels.
