Custom Graphic Overlays
Custom Graphic Overlays Manufactured for OEM Devices
Rethinking graphic overlays for real world use
The best high performance graphic overlay looks seamless on the surface — but it reflects a precise stack of engineering decisions beneath it.
At DuraTech, graphic overlays function as true HMI components, whether used in a medical device, appliance or electronic system. It’s the entrypoint to a integrated system that supports reliable, long-term performance.
What is a graphic overlay?
A graphic overlay provides the visual interface for your device’s controls.
Function & design: It uses color, graphics, text and textures to guide the user to the correct inputs.
Graphic overlays in context: It is the top layer of a printed user interface, such as a membrane switch or in-mold structural electronics (IMSE).
Performance: It can provides a durable surface that protects underlying circuits.
User experience: The graphic overlay is the entry point for the end user — the bridge between intention and activation.
A typical overlay stack-up
Each overlay is developed through material stack-up design, where films, inks, diffusion layers and adhesives come together as a unified system.
Engineering decisions across the overlay stack
Precision & tolerances: Visual and functional accuracy
To ensure the graphic overlay integrates correctly with underlying mechanics, DuraTech maintains tight tolerance and registration control throughout printing and converting processes.
- Close-tolerance die cutting and laser cutting that reduce risks such as misregistration and delamination
- High-precision print registration maintained within ±0.005–0.010″
- Burr-free edges that prevent raised material and support a clean, precise assembly fit
- Dimensional repeatability maintained across production batches
- Controlled color consistency to ensure visual uniformity from part to part
- Accurate cutout-to-print alignment that helps prevent light bleed around icons and windows
- Precise alignment between overlay features and underlying switches and sensors
Application environments for graphic overlays
Graphic overlays must perform reliably under a wide range of operating conditions. DuraTech designs interface components suited to the operating environment.
- High-touch interfaces requiring abrasion resistance and long cycle life
- Repeated exposure to cleaning agents, chemicals and disinfectants
- Outdoor environments with UV exposure, moisture and temperature variation
- Precision assemblies requiring accurate alignment with backlighting and displays
- Medical applications subject to sterilization and frequent sanitation
- Appliance interfaces exposed to heat, humidity, grease and repeated cleaning
- Industrial equipment exposed to vibration, impact and mechanical stress
DuraTech: A partner in reliable human-machine interfaces
The graphic overlay is where users interact with the machine — and where brand experience takes shape. DuraTech approaches every project with this understanding.
