Flexographic printing uses a printing plate made of rubber, plastic, or some other flexible material. Ink is applied to a raised image on the plate, which transfers the image to the printing substrate. The fast-drying inks used in flexography make it ideal for printing on materials like plastics and foils. This makes flexography the predominant method used for printing flexible bags, wrappers, and similar forms of packaging. The soft rubber plates are also well-suited to printing on thick, compressible surfaces such as cardboard packaging. Inks used in flexography are usually either water-based or solvent-based (Pferdehirt, 1993).
