>Comparision of Laser Dotted LGP and Silk Screen LGP
Actually, most manufacturers in China are still using ink printing now. From the appearance, they look the same, a piece of acrylic sheet with many round dots on it, but for laser LGP, all dots are created by laser.
In order to make sure the light is even on surface,the depth and distribution of dots are designed
according to how the light spread. It can be used at least 10 years. But for ink printing LGP, the dot
is printing by ink, after heating, the ink will absorb light and release harmful gas, day after day,
the LGP will become dark. Its life span is very short, at most 2 years
and do not good to environment.
