December 2, 2022 (the ninth day of November in the lunar calendar) is the birthday of Andre Liu, general manager of Print Area.

Offset printing ink must have high viscosity (dynamic viscosity η = 40 ~ 100Pa · s). When offset printing ink spreads on the inking unit rollers or transfers to the substrate, such as printing plates and blankets, the drying components in the ink do not cause the ink to harden.

Eagle catching chicks is a game often played by folk children. Choose one person to be the "Eagle", the leader to be the "Hen" and the rest to be the "Chicks". , It is more suitable for playing games on grass and plastic fields. As the mother of the chicks, the hen must do her best to protect the chicks, and must not make big moves.

For the second week of November, colleagues in the Print Area are all gearing up for Saturday's sport -- the debate. This is our first debate competition.

Water-transparent ink is the water-based screen printing ink itself that is white, becomes transparent when exposed to water, and restores after drying.

Infrared absorbing anti-counterfeiting ink is made by adding one or several near-infrared absorbing materials into the ink, and the near-infrared absorbing material is an organic functional dye. It has absorption in the near-infrared region, the maximum absorption wavelength is 700nm~1100nm, and the oscillation wavelength falls in the near-infrared region. Because the near-infrared absorption ink absorbs infrared light, if this ink is used in a certain part of the printed product, there is no Traces, but under the detection instrument, the corresponding signal or dark graphics can be observed.
