Understanding CI Flexo Printing Technology
CI flexo printing technology is characterized by its use of flexible photopolymer plates. These plates are mounted onto a central drum, which holds the substrate in place during the printing process. This configuration allows for consistent tension and precise registration, ensuring high-quality prints across various materials such as films, paper, and foil.
The process begins when ink is transferred from an anilox roller to the raised areas of the photopolymer plate. As the substrate passes under the plate, the ink is transferred onto it, creating the desired image or text. This method is particularly favored for its ability to produce vibrant colors and sharp details, making it ideal for packaging applications.
Applications of CI Flexo Printing Machines
CI flexo printing machines are utilized across numerous industries. Their primary applications include:
