A graphic overlay is a durable label that is part
functional and part aesthetic. The can be embossed to act as a functional key or to apply a 3D effect. Adhesive is usually die cut to avoid the window area and/or keys. Graphic Overlays can be supplied with clear windows for LED's and displays. UV Lacquer can be applied to provide localized variations in texture.
They can be used as a stand-alone graphic for the top layer of a membrane keypad and are sometimes referred to as the following :
- LED Labels
- Keypad Overlays
- Display Overlays
- Display Lenses
- Graphic Displays
- Window Overlays
- Control Panel Overlays
- Panel Graphics
- Switch Overlays
- Mylars
- Fascia Control Panels
- Self Adhesive Graphic Overlays
- Mark Resist Graphic Overlays
Graphic overlays are a key part of any control system as they are both functional and informative. These printed graphic products are the first item that an operator's eye is drawn to. Consequently, the overlay has a big influence on the user's first impression. Attention to detail, precise colour matching and intuitive graphics are critical factors in creating an effective graphical overlay.
Graphic overlays are used throughout many different industries which include Electronics, White Goods, Medical, Security and Marine. If you are looking for
features that are specific to your product we can design and manufacture graphic
overlays that include:
- Wide variety of Polyester and Polycarbonate finishes
- Materials selected for environmental suitability
- Anti-microbial finishes
- UV Stability
- IP65, IP67, IP68 rated
- Tactile or non-tactile feedback keys
- Rim, Pillow of Custom embossing
- Braille
- Integrated LEDs
- RFI/ESD/EMC Shielding
- Fibre Optic backlighting
- Interchangeability of key Legends
- Full turnkey production including sourcing of panels, Aluminium/steel or plastic
- High precision laser cut production virtually eliminating tooling costs
The two main materials that are used in the production of a Graphic overlay are
Polycarbonate and Polyester. We have direct supply and support from Companies
such as Sabic and 3M allowing is to develop products to exacting standards and
supporting our commitments to RoHS.
Polycarbonate (also known as Lexan) Is easy very easy to process, ink keying,
die cutting and forming are very easy with this malleable material. Generally,
if the overlay is mostly aesthetic then this is the correct choice as
it is slightly less costly than PET. If the graphic overlay is going to be in
contact with solvent based chemicals then this probably will not be suitable.
Polyester (PET) is a higher grade material and available with more surface finishes
and effects. Nearly always used when the overlay is more functional. For
example, if the design has raised keys or push button areas or if the
graphic overlay is to have a display. This material can also be laser cut which virtually
eliminates the need for tooling.
Features / Benefits
Graphic overlays are manufactured in a variety of shapes, sizes and materials
but share these common features and benefits :
- Durability
- Adaptable design, totally bespoke to Customers requirements
- Sub-surface graphics – Printing is done on the under-side of the
graphic
overlay so it doesn't degrade its graphic identity and won’t wear
out from use or cleaning
- Short lead times – approximately 2 weeks after artwork approval
- Adhesive selected to suit mounting application
