Embossing

Graphic foils such as overlays and membrane keypads may, after the printing process, go through embossing which highlights specific areas on the surface.

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 keypad 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.

Embossing of overlays and membrane keyboards is done by either hot or cold. The method depends on the foil material, and will naturally be part of the instructions related to the development of the overall solution.

In the cold proces, the tool is pressed against the workpiece and creates an elevation by stretching the cold foil.

In the heat proces, the tool is heated and pressed against the workpiece to stretch both the foil and colour without cracking.
