The basic padprinting process is simple enough in nature. This article will show how the padprinting process works and why it is especially suited for printing on irregular shaped objects (a.k.a. substrate) as well as flat surfaces.
The key elements to the padprinting process are the pad, the cliche', and the ink. Each of these elements are explained in greater detail in subsequent articles also found on this site. Together, these three elements allow more flexibilty in the types of products which can be printed using this process, than any other printing process.
The basic steps as illustrated below are as follows:
- The cliche' step - the image on the cliche' is inked via doktor blade sytern or inkcup while the pad travels to the image.
- The transfer step - the pad picks up the inked image from the diche' and travels to the subsbate.
- The print step - the pad makes contact with the substrate using just the right amount of pressure to deliver the image.
