Pad printing is a modern printing process that can be used to quickly transfer 2-D images on to all sorts of 3-D objects. However, before getting into a description of what pad printing is, it’s important to first define a few specific elements that pad printing relies on.
First, it’s important to understand gravure printing. Gravure put simply, is a process that etches an image onto the surface of a metal plate. This places the images – in ink form – in the recesses of the metal plate, unlike relief printing (where the image is raised). By filling the recesses with ink, and leaving the raised portions of the plate dry, the image can be transferred from the plate to the substrate quickly and cleanly. Gravure can produce very fine and detailed images on short or long runs in multiple colors.
Beyond the gravure printing process, pad printing also relies on plates – or cliches. In traditional offset processes, printing relies on transferring an inked image from an offset (the plate) to a rubber blanket which then makes contact with the print surface. When compared to other modern printing methods, offset printing with plates is one of the best solutions when it comes to economically producing commercial quantities of high quality prints, without requiring much maintenance. Today, cliches are made from metal or polyester.
