Silkscreen printing is the preferred method for producing high-quality durable legends and characters on our silicone rubber keypads.As with the silicone rubber material, Pantone references are used to achieve exact colour specifications, and keytops can be printed with single-colour or multi-colours.Standard set or special characters and legends may be incorporated into the keypad design, and reverse/inverse printing is also an option.
In pad printing, the surface of the printing plate contains the recessed image which is to be printed. The squeegee presses the ink into the recessed image and then removes the excess ink. At the same time, a silicone-rubber pad moves from the material to be printed to the printing plate. The pad is lowered over the printing plate, so adopting the image to be printed. This means that pad printing is an indirect process. The pad then lifts off and returns to the material used for printing.
