ABSTRACT:
A fluid metering roll is embossed with chains of cells, the cells of each chain being interconnected by channels. Certain of the walls of the cells are aligned at critical angles relative to the axis of the roll. The channels are oriented and arranged to assure a flushing of all portions of the cells so as to eliminate ink encrustation and maximize ink spread to avoid striations and moire effects.
