There are a lot of heavy machinery above the keys are designed to the character can be transparent effect, on the one hand, because of this beautiful atmosphere, on the other hand, this effect can be in the case of external light is not very good to distinguish the characters above the keys, will not lead to operation error. So what is the principle of the character transmittance key?
For the buttons made of silicone material, the character transmittance can be realized in two ways, one is to use radium carving process, the other is to use hollow screen printing.
Radium carving process refers to the natural color of silicone keys using transparent or translucent silicone material, after forming, spray a layer of opaque ink on the surface of the keys, and then at the top of the keys with laser etching way to carve out the required characters. Of course, there are also white characters, this is by spraying white oil, then spray black oil, and then radium carving can be achieved.
Hollow screen printing is the natural color of silicone keys using transparent or translucent silicone material, characters with screen printing process, but the use of the character part hollow, other parts of the opaque color to cover, so as to achieve the effect of the character light.
