Abstract
The present invention is directed to a variable density inking apparatus for use in a lithographic press, letter press, flexographic system or the like. The apparatus includes an anilox roll, means for feeding metered quantities of ink to the anilox roll surface, and a printing roll. A form roll is in peripheral engagement with the anilox roll and in ink delivering relation to the printing roll or to a further form roll. A characterizing feature of the invention lies in the provision of means for driving the form roll and anilox roll in the same direction while permitting relative speed variations in peripheral speed between the noted rolls in a ratio of from 1:1 to about 3:1 in either sense, thereby to enable an infinite variation in printing density.
