Signature Plastics manufacturers a variety of custom keycaps for customers with backlit requirements. This process typically involves molding keycaps in a translucent material, then painting them with a highly durable automotive paint and engraving legends through the paint using a CNC engraver. Producing our standard keycaps as double shot backlit keys has quality limitations related to flow channels required to fill islands in legends ( a, b, d, e, g, o etc.) as well as light interference from the mounting stems. Fill islands are referred to as 'counters' by typographers.
