In March 26th,we are loading our container to Myanmar.

It is international Women's day in March 8th.Glad to receive the rose in the morning from our boss.

UV fluorescent Ink is made by adding the corresponding visible fluorescent compound to the ink. Its anti-counterfeiting features are: the printed matter is invisible under ordinary light, and can emit glittering fluorescence under ultraviolet light. There are invisible and visible UV fluorescent inks. The special ink that emits visible light (400-800nm) is excited by ultraviolet light (200-400nm), which is called ultraviolet fluorescent ink. According to different excitation wavelengths, it is divided into short-wave and long-wave. The excitation wavelength of 254nm is called short-wave ultraviolet fluorescent ink, and the excitation wavelength of 365nm is called long-wave ultraviolet fluorescent ink. Blue and other colors; colored can make the original color shine; discoloration can make one color into another color.
