Graphic Panel Overlay PET, PC, PVC embossed button
Graphic overlay and control panels types
Screen printing process of custom graphic overlay includes front
printing and reverse printing. Apply them to membrane switches of
different materials and types, and you can divide them into the
flat overlay and raised overlay.
The flat membrane overlay is the simplest type, which touch screen
is also flat. Of course, some are backlit with LED display which
has application even in the dark. It mainly uses different PMS
colors of text, lines, and color blocks to indicate or distinguish
various functional parts. Also, the customer can choose different
industrial overlay materials and double-sided tape according to
their own needs. In general, we offer polyesters and polycarbonates
as raw materials.
The embossing overlay of membrane keyboard is developed on the
basis of the flat one. And, it’s a kind of relatively beautiful and
practical control panel. For membrane keypad company, the process
to create graphic panels is based on the ordinary one. Through an
embossing mold, graphic overlay manufacturers heat press it. So,
the button portion is slightly raised to form a stereo button.
Embossing buttons can accurately locate the shapes sizes of the key
body and improves the recognition speed. What’s more, the below
metal domes make the touch of the operator more sensitive. At the
same time, it enhances the decorative effect of the appearance of
the tactile switch.
