It is the printing method that is most frequently used for label and packaging printing. Flexo printing has become more popular as a result of advances in liquid ink technology, the switch to photopolymer cliché with glass-reinforced plastics technology, the development of anilox into laser engraving, and ceramic coating. Flexo has advanced to the point where it can compete with both offset and rotogravure printing for quality and short-run work with the consequent quality printing since it uses the most recent technology. Uneven surfaces can be printed on using flexo printing. Additionally, it is printed on aluminum foil using a specific ink and the flexible packaging materials cardboard, kraft, and plastic films.
