Graphic Overlay

What is Graphic overlay ?
Graphic overlay is an interface layer which is made of polycarbonate or
polyester with an adhesive backing. It can be applied to many industries
including, Residential and commercial appliances
Machinery control panels Medical equipment
HVAC equipment Gas station pumps
Automotive dashboards

A functional membrane graphic overlay is designed for use with rubber keypads,
membrane switches or as a touch screen panel interface for control panels. In
these applications, the printed graphics and text are used to providing
operational instructions or safety warnings and label overlay buttons and
controls.

However, with an aesthetic purpose, decorative membrane switches graphic
overlays and panel overlays are printed with custom graphic panel, company
logos or product information. They act as an intermediary between the user and
the machine through functional descriptions, without conductive traces or
circuitry.

The membrane switch overlay or custom control panel overlay provides a variety
of embossed keys, matte or glossy finishes, and a protective coated overlay to
reduce the likelihood of fading. It also includes different material
thicknesses from 0.125mm to 1mm to meet customers' specific applications.

Graphic Overlays for Any Industry
Custom graphic smart overlays can improve the overall appearance and prevent
moisture, dust, and debris from penetrating the electrical components such as
switches or touch screens. Some of the common uses include:

Residential and commercial appliances

Machinery control panels

Medical equipment

HVAC equipment

Custom Graphic Overlay Capabilities
Specializing in graphic design overlays as static components for membrane
switches and rubber keypads and touch panel, we will help you design a
customized graphic overlay which meets both functional and aesthetic needs. We
can offer the following services:

Digital overlay printing

Prototyping

In-house embossing

Custom control panel overlay printing

Laser & die-cutting

Custom graphic overlays can be made in sizes from to 30" to 40". Additionally,
in order to improve visibility in low light applications, backlighting can also
be added to the overlay panels. We also offer special ultraviolet selective
textures and ultraviolet hard coat treatments which can protect lens areas from
chemicals and scratching.

How to Design the Graphic Overlay?
Sample: Provide drawings of graphic overlay prototypes that all dimensions and
physical characteristics including colors or actual samples for copy are
clearly shown.

Colors: Identify the colors which you want your switch overlays to have by
Pantone (PMS) RAL color number or a color sample. It is important to supply the
exact standard for which our color match will be evaluated.

Borders and Outlines: Avoid circles within circles, or outlines which are close
to cutouts or outer edges because any misregistration will be visually
accentuated.

File Format: It's best to receive design files from the native software
packages. (ie Adobe Illustrator, Corel Draw or PDF files)

Background: Light text and dark backgrounds will show less wear and dirt and
greater clarity. Try making the control panel overlay or the membrane overlay
drawings clear.

Text: Block lettering provides the most legible copy. Try to use common fonts.
Positive letter strokes should be a minimum of .008'' and .012''for negative
letter stroke.
