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 that has a first width and that is disposed between the substrate and a series of print heads. The jet plate can also include a series of apertures formed in the jet plate that each correspond to one or more of the print heads, as well as a cutout portion at a first end of the jet plate that has a second width less than the first width.

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.

Abstract: A linear rotary encoder includes a pair of rotational surfaces. A contact belt has a first end coupled to a first rotational surface in the pair and a second end coupled to a second rotational surface in the pair. The contact belt is driven to rotate around the pair of rotational surfaces by a driving force applied to media to move the media from the first end toward the second end. An encoding scale is coupled to an inner surface of the contact belt. A reader is positioned to read the encoding scale as the contact belt rotates around the pair of rotational surfaces. The reader generates an output signal indicating a position of the media based on reading of the encoding scale.
