Abstract: Apparatus, methods, and systems for dynamically modulating radiation energy in a printing system are disclosed. A system receives data comprising an image pattern for depositing ink on a substrate. The system determines one or more ink properties for the ink configured to be deposited onto the substrate. The ink properties and/or a color of the substrate are used to determine a corresponding energy level value for a radiation lamp. The ink is deposited in the image pattern on the substrate. One or more radiation lamps heat the substrate and the ink, wherein the radiation lamps are configured with the corresponding energy level values.

Abstract: 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.

Abstract: A printing system includes a driving belt configured to drive media through the printing system relative to one or more print heads and a vacuum conveyor system. The vacuum conveyor system includes a vacuum chamber cover having a first surface and a second surface opposite the first surface, as well as a plurality of slots through the cover that form openings from the first surface to the second surface. A seal, disposed within and extending along at least a portion of a length of a respective slot, is drivable to open or close the respective slot. A vacuum chamber below the second surface of the vacuum chamber cover is configured to apply a vacuum to the media through the plurality of slots. The applied vacuum constrains the media on the driving belt by flattening it against the driving belt.

Abstract: A printing system having a vacuum transfer belt conveyor includes a fixed or movable perforated platen that supports workpieces, e.g., substrates, boards or other parts, to be printed. The printing system is configured to apply vacuum action through apertures or perforations defined through the perforated platen. In an embodiment, the print system is configured to mitigate deflection of ink drops, through the implementation of both a passive system, which reduces air flow in the region below the a print bar that includes one or more printheads, as well as an active system, which distributes the workpieces, e.g., substrates or boards, with respect to perforations in the transfer belt. In some embodiments, the perforated platen is comprised of a plurality of modular plates.
