Crystal marking usually refers to a printing technology that prints colored patterns or characters on the surface of transparent or light-colored materials, with high printing quality, clear images and good fullness. In order to achieve this effect, we need to use Bai Mo to improve the level of light, shadow and color saturation.

The so-called Bai Mo refers to the ink made by adding white pigment particles into the ink. Similar to black ink, Bai Mo can also be dried and cured immediately under the irradiation of a specific ultraviolet light source. Bai Mo printing can achieve more unique visual effects, such as dazzling colors and expression of different tones. For some transparent, light or even pure black brand prints, Bai Mo can be used as the backing of the background of the bottom plate, which can make the color expression of the color part more beautiful and realistic.
