The function of a pad printing pad is to transfer ink from the etch on a pad printing plate (cliché) to the product being
printed. Pads are made from silicone rubber. The reason for this is because solvent based inks do not adhere to the pad. As a result, the ink is easily transferred to the product. This ability allows for the ink to easy transfer to the product and re-usability. Pad printing inks are either one- or two- component inks. As a result, the inks are either mixed with solvent
and hardener. Solvents, hardeners, and constant compression and decompression of the silicone pad eventually degrade
the pad material over time. When the pad is worn out, it has reached it's life span.
Every pad printing pad has a limited lifespan, but proper care can help extend its longevity.
