  • the web material between one or more arrangements of a printing cylinder (plate cylinder) and a counter-pressure cylinder (impression roller) is passed, which roll in opposite directions on the web material.
  • the impression cylinder picks up ink from a paint pan in cells of its surface and the excess is scraped off. The ink is transferred to the pressure medium passing through the printing cylinder and impression cylinder.
  • the printing unit also includes a printing cylinder and an impression cylinder, between which the printing material is passed.
  • Flexographic printing is a high pressure process in which the raised areas of the printing form are image-bearing on the circumference of the printing cylinder.
