Flexography is a direct rotary printing method utilizing relief printing plates made from photopolymer plates, elastomer sleeves, or rubberized cylinders.
The advantages of flexography include:
Flexographic inks are liquid and highly volatile, allowing for rapid drying through the immediate evaporation of the solvents they contain.
The most prominent application is printing on plastic films for food packaging across various substrates.
The primary solvent used in these inks is ethyl alcohol; however, water-based inks can also be used in flexography. Other organic solvents are added to the various ink series to regulate drying characteristics.
