What is diffusivity?
-
We refer to the diffusion of light (Haze: cloudiness). By diffusing light, a frosted glass-like effect can be achieved.
-
What is Phosphorescent ink?
-
Phosphorescent ink contains pigments with luminescent properties that absorb and accumulate light rays from the sun, electric lights, etc., and gradually emit them, so the absorption-accumulation-emission process can be repeated many times. It can also be applied to safety and energy saving measures.

What is dead front (concealed) printing applying the IR transparency function?
-
As mentioned above, IR transmittable inks allow control of transmittable colors, and variation in hue can be achieved by overprint with metallic inks. Therefore, various decorations are possible with “dead front (concealed) printing,” printing that cannot be seen unless illuminated by light.
Note1) Transmittance varies slightly depending on the transmitted color.
Note2) Infrared transmittance decreases by 10-20% when over printed with metallic inks. Related Links Introduction of IR Transmittable Ink and Dead front PrintingRelated Links

How do you use IR transmittable ink (IR Transmitting Ink) ?
-
After printing IR transmittable ink (IR Transmitting Ink) onto transparent PC or PET substrate sheet, the ink has the special function of blocking the shorter wave-length visible rays and ultra violet rays and allows the longer wave-length infrared rays to penetrate. One example of an application that this ink is used for is the signal receiving filter of remote control devices.
