UPWARDS JETTING DIGITAL PRINTING PLATFORM
A printing platform includes a printing engine with one or more printheads arranged such that the ink drops are jetted vertically upwards against the action of gravity; and a substrate transportation system where the normal to the surface in contact with the substrate is parallel and with opposite direction to the travelling direction of the jetted ink drops. It is necessary to counteract the weight of the substrate during the printing process to avoid it from falling under the action of gravity. This is achieved through any of a mechanical element that interferes with the falling of the substrate and that keeps it in place; or a system that generates adhesion forces between the element that transmits the motion to the substrate, typically a conveyor belt, and the substrate through the action of electrostatic forces, an air pressure differential between both faces of the substrate, or any other suitable mechanism.

Image forming system
An image forming system includes a receiving unit that receives an adjustment value for adjusting a value of an applied voltage in case of transfer in response to an operation of a user, a detector that detects a value of an electric resistance of a print medium as a resistance value. A first control unit controls the applied voltage based on the adjustment value indicated by the second adjustment value information included in the adjustment update information received by the first communication unit. A second control unit uses the adjustment information transmitted respectively from the plurality of image forming devices and determines the adjustment values to be used in the plurality of image forming devices. A second communication unit transmits the adjustment update information including the second adjustment value information indicating the determined adjustment values respectively to the plurality of image forming devices.
PRINT ADJUSTMENTS BASED ON AIR MEASUREMENTS
An example method is described in which a property is measured associated with air flowing through a print gap between a print head and a printing substrate, the print head to eject a print fluid on the printing substrate; an ejection of print fluid is adjusted from the print head based on the measured property.
Inkjet Printer
The purpose of the present invention is to prevent the flow of air flowing from the outside of a cover part into the cover part via an ink droplet passing hole as air accompanying printing droplets outflows. An inkjet recording device is provided with: a recording mechanism (printing mechanism) having an ink room 101 that ejects an ink column 107, charging electrodes 103A and 103B that charge ink droplets 106 generated from the ink column 107, and deflection electrodes 105A and 105B that deflect charged ink droplets 106A; and a cover part 118 that has an ink droplet passing hole 117 through which the ink droplets 106A deflected by the deflection electrodes 105A and 105B pass and covers the recording mechanism. The inkjet recording device causes the ink droplets 106A to land onto a recording object 116 that moves relative to a recording head 100 to perform recording. A vent hole 130 is provided in a lateral surface of the cover part 118.
