Printing requirements
Opumum print curvature
Graphic alignment
Printing on concave surface
Drastic Key height difference
Printing large surface area

Silicone rubber keymat manufacturing requires several secondary processes to achieve a complete keymat. It is important to consider fool-proofing in product design to help cut down the rejects and increase yield.

To achieve optimum print results and abrasion resistance, minimum radius curvature on top profile of knob shall be as shown:

Avoid drastic difference in key heights as this will cause difficulties in printing:

To enhance the abrasion resistance of large print area, you may consider the following:
