Document Summary
Silk-screening is inexpensive and yields a high-quality print with good physical properties. The silk-screening process exerts only sight pressure on the part during decoration. Since registration for intricate designs is difficult, the process is usually limited to two colors. Flexography is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress which can be used for printing on almost any type of substrate including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging. It is also well suited for printing large areas of solid color. Pad transfer printing has been used for many years to decorate watch faces and chinaware. Pad transferring uses a silicone rubber pad as a printing surface. The pads are created from photo-engraved plates made of hard steels.
