Flexographic printing (often referred to as flexo printing) is a high-speed printing process that uses a flexible printing plate to transfer ink onto a substrate. The printing plate is made of a flexible material, typically rubber or polymer, that has a raised image of the design to be printed.
During the printing process, ink is transferred onto the printing plate, which then applies the ink to the substrate (typically a roll of paper or plastic film). The ink is transferred using a series of rotating cylinders, including an anilox roll, which controls the amount of ink transferred to the printing plate, and a pressure roll, which presses the substrate against the printing plate. Flexo printing is commonly used to print packaging materials such as labels, bags, and corrugated boxes. It is also used for printing on a variety of other materials including paper, plastic, metallic films, and foil.
Flexo printing offers several advantages over other printing processes, including the ability to print on a wide variety of substrates, high printing speeds, and the ability to print multiple colors in a single pass. It is also a relatively inexpensive printing method, making it a popular choice for many printing applications.
