Abstract
The present embodiments relate to a printing apparatus capable of mitigating/preventing instances of turbulent deviation of ink jetted from print heads when printing onto a substrate, a severe form of which looks like woodgrain. The printing apparatus can include a jet plate disposed on a subjacent surface of the printing apparatus that can include a series of apertures formed in the jet plate that are configured to receive corresponding print heads of the printing apparatus. The jet plate can also include a set of wings extending from a first end of a central portion of the jet plate. The set of wings can form a cutout portion of the jet plate that can modify a direction and/or velocity of a flow of air from the cutout portion along the printing area to mitigate/prevent a woodgrain defect occurring when distributing a material onto the substrate.
