Abstract
Reproducing a predetermined pattern on a medium, by for example, an apparatus that includes in combination a source of colored ink, a primary source of compressed air, a spray head including a housing having an inner ink chamber in flow communication with the source of ink, an outer air chamber in flow communication with the source of air and surrounding the inner ink chamber, a spray nozzle having an outside diameter and an internal longitudinal bore connected to the inner ink chamber and extending forward of the housing. A spray shield has an outer surface adjacent the medium and an inner surface positioned adjacent to and spaced from the housing and has a transverse opening therethrough in alignment with the nozzle. An auxiliary air supply has a pressure significantly less than the pressure of the air from the primary source of compressed air. The auxiliary air supply is in flow communication with the space between the shield and the housing thereby to force clean air through the space and out through the spray shield opening.
