Graphic overlay definition and uses
When consumers interact with products, they will typically use a graphic overlay. Graphic overlays are printed materials designed for installation on top of, or in front of, another object or form of signage. These types of graphics can be transparent or opaque, depending on usage and exterior lighting. Unlike many forms of signage, which are designed first and foremost to attract attention, graphic overlays can serve a multitude of purposes.
Membrane switch overlays are the most common overlay graphic. Membrane overlays are printed graphics on semi-rigid plastic that are placed over the top of buttons or displays. The overlays protect the mechanisms while offering directions, styling, and protection to the mechanisms underneath. These overlay types can be most commonly found on appliances, tools, or equipment that feature buttons or power. This makes graphic overlays an ideal form of instructional signage. Their ability to be selectively transparent can make them visible on a wide array of different color surfaces.
When graphic overlays are printed, clients have an option of two styles. The first type prints on the front of the substrate (1st surface) while the second prints on the backside of the substrate (2nd surface). The advantage of 2nd surface printing is that the material acts as additional protection because the ink isn’t exposed. Since the printed display is hidden by a layer of substrate material, it will degrade far more slowly to wear & tear and weather conditions.
Common uses for graphic overlays include:
- Visual improvements: Used to cover up an unattractive area or add panache to an empty space.
- Membrane switch overlays: Used to identify button and lever functions on a control panel.
- Provide additional information: Can be placed over a traditional display to add details such as price and more product data.
Common graphic overlay materials
Graphic overlays can be printed on a variety of materials, including PVC vinyl, PETG, Acrylic, and polystyrene. Two of the more common options include:
Lexan (polycarbonate): Material that is easy to die cut, print and customize. The substance is durable, typically only starting to show wear after 100,000 actuations. This material tends to be transparent, regardless of thickness. An affordable graphic base, it should be covered with protection in any area exposed to chemicals.
Mylar (polyester): A thin and hardy material, Mylar does not show any signs or wear, even after 100,000 actuations. While this material can be pricey, it holds up exceptionally well in harsh environments, including areas with hazardous chemicals present.
