Mouldlife Ltd are an official pad grade silicone distributor and target the main manufacturs of the pads. Pads can vary in size and appearence depending on their use.
Pad printing is the transfer of ink, via the pad to anoher surface. It was primarily used in the ceramics industry, for printing patterns on difficult surfaces, (curved etc.) But can also be used to print codes on the bases of tins etc.
