Flexo printing is a popular printing technique used in the packaging industry. It involves the use of a flexo printing machine, which uses flexible photopolymer plates wrapped around printing cylinders to transfer ink onto substrates such as paper, cardboard, or plastic. The flexo printing process is known for its ability to print high-quality images quickly and efficiently, making it a cost-effective option for large production runs. Flexo printing machines can also be customized to print on a variety of substrates, allowing for versatility in packaging design. Additionally, the use of water-based inks in flexo printing makes it an environmentally friendly option compared to other printing techniques.
