Pad Printing
Pad printing is a printing process that can transfer a 2D image to a 3D object. This is achieved by using an indirect offset printing process (gravure) that involves transferring an image from the cliché via a silicone pad to a substrate. Pad printing is used for printing on products that would otherwise be difficult to print in many industries, including medical, automotive, promotional, clothing and electronic items, as well as household 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 on both the cliché and the pad allow it to leave the engraved image area in favor of adhesion to the pad and subsequently detach from the pad to adhere to the substrate.
The unique properties of the silicone pad allow it to take the image from a flat plane and transfer it to a variety of surfaces, such as flat, cylindrical, spherical surfaces, compound corners, textures, concave or convex surfaces.
