Question:

What is the effect of sublimation and color laser printers when printing photos?

Because it is used on the desktop link so the use of sublimation printer can print SD card and other advantages in fact does not make sense, but from the effect of similar price of the two printers which is better?

Answer:

Sublimation printers are the best printable devices in the heat transfer printer; however, the print speed is slower, the print media is required to be high, and the printing costs are very high.
Color laser printer is a low-cost, high-quality high-quality color print output device. But in contrast, color laser printer image printing effect is not very good, the performance of the overall color saturation in the screen darker, less transition level, more close to the print rather than photos. And the traditional print output on the surface of the total attached to a layer of silicone oil, so that the entire picture of the reflective are strong.
Sublimation printer is the basic principle of color dyes through some means "move" to the print media, the formation of brilliant images. The source of color dyes is the ribbon, generally divided into yellow, magenta, cyan, black four ribbons (there are some sublimation printer with yellow, magenta, green three colors), and then set the ribbon in a drum , The drum is equipped with tens of thousands of semiconductor heating elements, from these heating elements constitute the print head, at a certain temperature by the semiconductor heating elements on the drum print head solid pigment directly sublimated into a gaseous state (solid not through Liquefied directly to the gaseous), and then sprayed onto the print media, each heating element can be adjusted out of 256 different levels of temperature, the higher the temperature the more the gas pigment, so as to rely on temperature to adjust the color ratio on the print media And the degree of shade.
The color laser printer prints the dot matrix generated by the printer controller into the final image through the print engine. The laser generator generates a laser beam for each print point and generates a laser for printing the dot size in the horizontal direction by the rotation of the rotating mirror and the correction of the lens. The surface of the imaging drum is smooth and can be charged, and it can be discharged by light. When the laser light is on the imaging drum, the charge that has been precharged is discharged. As the imaging drum continues to rotate, a series of laser spots are hit on the drum. When the drum is rotated, it also passes through a developing roller, where the discharge point absorbs the charged toner, and the drum is rotated with the drum. Its main function is to The already formed toner image is copied. As the color laser printer has four-color toner, so the above imaging, the transfer process will be repeated four times, the last transfer drum will form a four-color image. After the transfer is completed, when the charged paper passes through the transfer drum, the printing paper draws the toner on the transfer drum to form a color image output.
