MIX-HF ink has realized "high transparency" and "excellent leveling". (e.g., haze value(*) of MIX-HF000 MEDIUM reaches as much as 0.6.) And it can be used in optical components which require transparency such as camera lens for mobile phones because of its high transparency.
(*) Haze value
Haze value indicates the rate of diffuse transmittance light to non-diffuse transmittance light. That is, the smaller such value is, the better transparency is.
Haze value (%) = Td/Tt × 100
(Td:Diffuse transmittance rate Tt:Transmittance rate of all range light rays)
The examples of printing characters on resin sheet by using MIX-HF000 Medium are as follows. Please see high transparency and excellent leveling of MIX-HF ink below.
It is not possible to recognize printed characters because of its high transparency and excellent leveling.
We could confirm the edge of printed characters by slanting the sheet. However, only a part of the characters could be recognized.
By curving the resin sheet and shedding light on the surface, we could finally see the printed characters (TEIKOKU).
