By embossing, areas on an otherwise smooth surface are highlighted with an elevating 3D effect. This creates a focus on selected areas, while the application is made more efficient.
For keys on a keyboard or overlay, raised embossing can be created on the entire key area, or a surrounding frame and border around each key can be created with frame embossing.
All elements on the foil, like buttons, logos, symbols and numbers, can be highlighted in customised formats.
If the design includes braille, this can also be done.
