Pad/tampon Printing:

In pad printing, also known as tampon printing, an inked image is transferred from a photo-etched plate to a thick, soft silicone pad. The pad is then pressed against flat, curved, or tapered surfaces leaving single or multi-colour images. The pad can wrap itself as much as 180° around an object. Pad printing inks, specifically formulated to adhere to various substrates, are used to decorate metals and ceramics as well as a wide range of plastics.
