Pad printing is a printing process that can transfer a 2-D image onto a 3-D object. Pad printing is used for printing on otherwise impossible products including medical, automotive, electronics, appliances, sports equipment and toys.
Cost — pad printing is primarily chosen due to its low cost.
Pad printing can imprint any colour text, on any part of the keycap, on any colour plastic.
Because the legends are printed, pad-printed legends support intricate typography.
