In one example, an aerosol control system for a printer includes an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web and a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow.

A droplet discharging apparatus (10) includes a supporting section (20) including a supporting surface (21) that supports a medium M, a first head (81) including a first nozzle that discharges first liquid onto the medium supported by the supporting surface (21), a second head (82) including a second nozzle that discharges second liquid that promotes curing of the first liquid by reacting with the first liquid onto the medium M supported by the supporting surface (21), a carriage (83) that reciprocally travels in a width direction while holding the first head (81) and the second head (82), an air sending section (70) that generates airflow in the front direction in an discharging area facing the supporting surface, and a shielding section (85) that shields the airflow in the front direction in the discharging area R1.

An image formation device includes a first portion and a second portion. The first portion along a travel path is to receive droplets of color ink particles within a dielectric carrier fluid onto a substrate to form an image. The second portion includes a charge source to emit airborne charges to charge the color ink particles to move, via attraction relative to the substrate, through the carrier fluid to become electrostatically fixed relative to the substrate and to become additionally fixed, in their electrostatically fixed position, via distance-dependent, molecular forces relative to the substrate. The duration of additional fixation via distance-dependent, molecular forces may be at least greater than a duration of the electrostatic fixation.

A deposition module within a web press for inhibiting media deformation may include a fluid deposition device located on a side of a media, and a processing device to control the fluid deposition device to selectively apply a wetting agent to the media. The deposition of the wetting agent may be based on the location of content printed on the media as defined by print data.

A liquid discharge apparatus includes a body and a carriage disposed inside the body. A head is mounted on the carriage. The head discharges ink onto a recording medium and generates ink mist. An ink mist collector includes a fan that generates an air current that circulates in an air flow direction inside the body. A filter collects the ink mist generated by the head. At least one duct adjusts the air flow direction. An encoder is mounted on the carriage. The encoder is disposed downstream from the fan and disposed upstream from the head in the air flow direction.

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.
