Rotary screen printing machine is a type of ink-jet printing equipment used to print designs onto cylindrical objects such as bottles, cups, and containers. It works by placing the cylindrical object onto the printing bed, and a screen or stencil with the desired design is wrapped around a cylindrical drum. Ink is then applied onto the screen or stencil, and the cylindrical drum rotates, transferring the ink onto the cylindrical object, creating the printed design. Rotary screen printing machines are commonly used in the packaging industry. Compared to flat screen printing machines, rotary screen printing machines have a higher production speed and can print more accurate and consistent designs on cylindrical objects.
