Achievements in doctor blade technology have resulted in high quality flexographic printing and pollution prevention through controlled ink transfer from the ink container to the substrate. The average two-roll system with its ink fountain, fountain roller and anilox roll is a veritable open reservoir, exposing large quantities of solvents that are readily evaporated. The chambered doctor blade halts this evaporation. Ink enters the chamber from the reservoir or ink sump by a pump. The ink is held in the manifold area, with a small area exposed to the anilox roll. A doctor blade is positioned to shear off the excess ink as the anilox turns, returning all extra ink to the chamber. A second plastic or metal blade retains the ink within the chamber. The chamber is sealed off completely so that no ink goes beyond the width of the unit.
