Pad Printing is the process where the desired image is printed on a sheet of laser film which is then transferred onto a printing plate. The inked image is then transferred from the photo-etched plate to a thick, soft silicone pad. Each pad differs depending on the size and shape of the print. The pad is then pressed against the object transferring the image from the pad to the 3D object. Pad printing is usually used for printing onto hard objects such as pens, bottles, mugs etc. Only one colour is printed at a time but, depending on the object, up to four colours can be pad printed.
