1. Printing Requirements

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.

2. Opumum Print Curvature

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

3. Graphic Alignment

4. Printing on Concave Surface

5. Drastic Key Height Difference

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

6. Printing on Large surface area

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