The printing effect is exposed deep substance through the surface material evaporation, or through laser beams lead to chemical and physical changes of the surface material “carved out” marks, or burned part of the material through the light, show the required etching patterns, text, bar codes, two-dimensional code and other graphics.
High photoelectric conversion without power coupling loss, save operating costs, laser beams, long service life, maintenance free, 100 thousand hours without supplies. The overall integration of compact structure, small occupied area, convenient transportation, marking speed, high efficiency at the same time processing volume increased significantly, to speed up the user return on investment professional metal printing it has no contact, no cutting force, has the advantages of small thermal effect, to ensure the accuracy of the original metal workpiece, increase the aesthetic.
Because the laser beams most of the light of the low cost, the performance of the color gamut is just passable. The color gamut is low, it means to show subtle color changes. For example, there are many kinds of red, only high color gamut can reflect the subtle differences between the different red color gamut. It becomes a key index of color technology.
At present, the new display technology in almost all color gamut has improved, such as laser beams quantum dot technology and so on, the performance of color is better than the traditional LCD panel. But these display technology can realize large screen, to experience the 100 inches above the screen, also is to rely on projection technology.
