摘要:
An embodiment is a method and apparatus to meter ink for electrographic printing. An ink loading mechanism having an anilox roller fills ink from an ink supply into cells in the anilox roller having a plurality of valleys and lands that form the cells. The ink loading mechanism causes the valleys to be full or nearly full with the ink. The anilox roller rotates in a first direction. A blanket roller rotationally engaged with the anilox roller pulls the ink out of the cells and causes the valleys to be partially filled. The blanket roller rotates in a second direction. A first cleaning blade cleans tops of the lands of the cells.Another embodiment is a method and apparatus to meter ink for electrographic printing. An ink loading mechanism having an anilox roller fills ink from an ink supply into cells in the anilox roller having a plurality of valleys and lands forming the cells. The ink loading mechanism causes the valleys to be full or nearly full with the ink. The anilox roller rotates in a first direction. A soft blade positioned slightly below surface of the lands removes ink from the cells and causes the valleys the partially filled as the anilox roller rotates. A hard blade positioned at the surface of the lands to clean residue of ink on the surface of the lands as the anilox roller rotates.
