Abstract
A method for manufacturing keycap includes applying a first coating layer on a surface of a keycap layer, applying a second coating layer on top of the first coating layer, etching at least a portion of the first coating layer to a first depth to form a first etched area, and etching at least a portion of the first etched area to a second depth to form a second etched area.

2 more elements
A keycap, comprising:
- a keycap layer;
- a first coating layer covering at least a portion of the keycap layer;
- and
- a second coating layer covering at least a portion of the first coating layer;
- wherein a first portion of the first coating layer defines a graphic having a first depth and a second portion of the first coating defines a border surrounding at least a portion of a perimeter of the graphic having a second depth greater than the first depth.
