ABSTRACT OF THE DISCLOSURE An improved ductorless liquid distribution system utilizes a plurality of side-by-side mounted radially- compressible roller elements to transfer ink from a reservoir immersed fountain roll in the form of sinusoidal bands onto a longitudinally vibrating distribution roll. The pressure of the roller elements against the fountain and distribution rolls is individually adjustable to control the deformation of the rollers and thus the width of the bands. The distribution roll vibrates an amount equal to the longitudinal spacing between rollers to provide complete inking coverage and the rolls and rollers are relatively dimensioned to obtain the crisscrossing of successive sinusoidal bands and smoothing out thereof by the addition of other vibrating rolls. In a described embodiment for high speed printing presses, the need for a keyed blade and an oscillating ductor is eliminated.
