Flexography is the predominant method used for printing flexible bags, wrappers, and similar forms of packaging. Both sheet-fed presses and web presses are used in flexographic printing. The soft rubber plates used during flexographic printing are also well-suited to print on thick, compressible surfaces such as cardboard packaging. Inks used in flexography are usually ultra-violet, water-based or solvent-based. The fast-drying inks used in flexography make it ideal for printing on materials like plastics and foils.
