Disclosed herein is a material ejector (e.g., print head) geometry having alignment of material inlet channels in-line with microchannels, symmetrically disposed in a propellant flow, to obtain smooth, well-controlled, trajectories in a ballistic aerosol ejection implementation. Propellant (e.g., pressurized air) is supplied from above and below (or side-by-side) a microchannel array plane. Obviating sharp (e.g., 90 degree) corners permits propellant to flow smoothly from macroscopic source into the microchannels.

A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in succession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.

The head (1) for the three-dimensional printing of molten metal comprises a hollow body (2) comprising: a first chamber (3) adapted to contain a molten metal (4) in which a dispensing opening (5) is formed for the dispensing of the molten metal (4); a second chamber (9) adapted to contain an operating fluid (10) and connected to pressure variation means (11) adapted to define a pressure difference between the first chamber (3) and the second chamber (9); and a dispensing assembly (12, 13) comprising a flexible laminar element (12) separating the first chamber (3) and the second chamber (9), the laminar element (12) being deformable by means of a pressure variation in the second chamber (9) and the deformation of the laminar element (12) determining the outflow of the molten metal (4) from the dispensing opening (5).

A method is provided of digitally imaging a secure portion and a non-secure portion of scratch-off-coating protected documents of at least one game using middleware. The method includes: (a) generating the secure variable indicia in non-vector raster format; (b) generating vector graphics to be imaged on physical document locations; (c) assigning the secure variable indicia in a non-vector raster format to documents in and shuffling the documents throughout a print run; and (d) linking via middleware the secure variable indicia in the non-vector raster format to associated vector graphics variable indicia to be digitally imaged on the documents and to generate vector graphics-formatted data for each document in the print run. The secure variable indicia assignment and shuffling are executed by non-vector raster game generation software output that is reinterpreted by the middleware to produce related vector graphic output for the secure variable indicia.
