Abstract
Apparatus for depositing liquid droplets in a printing operation employs a member having a receiving surface and being moved at a speed high enough to cause the generation of a gaseous boundary layer along the receiving surface. The stream of droplets is projected at right angles to the rapidly moving receiving surface and a stationary intercepting device is provided to remove, deflect or slow down the boundary layer upstream of the locus where the droplets impinge upon the receiving surface. If the receiving surface is provided on a cylindrical member, the intercepting means may comprise a stationary cylinder surrounding the receiving surface with a clearance of 0.5-2 millimeters. Regardless of the configuration of the receiving surface, the intercepting means may employ one or more stationary deflecting blades or one or more suction nozzles having orifices closely adjacent to the receiving surface immediately upstream of the locus of impingement of droplets.
