Q) What is the best material to be used in a graphic overlay?
A) It all depends on the application. For membrane switch overlays we recommend polyester because of its chemical resistance and its ability to be actuated in excess of 1,000,000 prior to any sign of failure. Our polyester material is treated with a first surface hard coating that allows the overlay to survive in even the harshest environment.

Q) What overlay thickness should I choose?
A) For excellent tactile feedback "feel" in a switch with stainless steel dome construction, choose an overlay thickness between .006" and .008." This thickness range will be durable enough to hold up to numerous switch cycles. A thicker overlay will significantly decrease tactile feedback (give a heavier feel).

Q) How are the graphics printed?
A) We print the graphics with traditional screen printing or with our new state of the art Raster Daytona UV Flatbed Digital Press. If the application is for very high volume, the most cost effective way to print is screen printing. If the application requires low to mid volume with high end "eye-popping" four-color process graphics, we will print on the Raster Daytona Digital Press. All graphics are printed on the second surface to protect the image.

Q) What colors are available?
A) We can print just about any color or graphic image that can be designed.

Q) Can embossing improve the look and function of my overlay?
A) Depending on the design creativity, embossing can dramatically enhance the look of the overlay. It can add to the function of the switch as well. There are two basic ways to emboss. The first is the conventional method, metal to metal with male and female dies. This is fine for most applications, but does have height-of-emboss-area limitations that must be understood. The second method, hydro-forming, allows for a higher emboss but is more expensive.
