Automatic Poly Offset is a type of printing process used to print on a variety of substrates, including polythene films, paper, and cardstock. It is a type of offset lithography that uses a specialized printing press designed to handle flexible substrates like polythene.The printing process involves transferring ink from the printing plate to a rubber blanket, which in turn transfers the ink onto the polythene substrate. The automatic poly offset printing machine is equipped with a series of rollers and cylinders that ensure the ink is transferred accurately and consistently onto the substrate.
