Pad printing is a printing process that can transfer a 2-D image onto a 3-D object. This is accomplished using an indirect offset (gravure) printing process that involves an image being transferred from the printing plate (cliché) via a silicone pad onto a substrate (surface to be printed). Pad printing is used for printing on otherwise impossible products in many industries including medical, automotive, promotional, apparel, electronics, appliances, sports equipment and toys. It can also be used to deposit functional materials such as conductive inks, adhesives, dyes and lubricants.

Physical changes within the ink film both on the cliché and on the pad allow it leave the etched image area in favor of adhering to the pad, and to subsequently release from the pad in favor of adhering to the substrate (material being printed).

The unique properties of the silicone pad enable it to pick the image up from a flat plane and transfer it to a variety of surface (i.e. flat, cylindrical, spherical, compound angles, textures, concave surfaces, convex surfaces).

Since the late 1960s, an old printing method, which had been particularly well established in the watch-making industry, has been an unexpected boom. Pad printing was discovered for newer, broader applications and with the help of silicone pads and new machine constructions it truly blossomed. Pad printing machine manufacturers began multiplying and satisfied the real market need for printing and decorating parts in a simple and inexpensive way. Pad printing allows new designing possibilities for engineers and designers as a result, the products are becoming more attractive and functional.

Today, pad printing has reached a technical advanced state and the range is quite diversified.
