Abstract: A printing technique is presented for efficiently printing (i.e. with production lines rates at high resolution and high accuracy) on outer surfaces of a plurality of objects passing in an optimized stream through a printing route/zone. According to this technique, at least one array of printing head units is provided being configured to define at least one printing route along a printing axis, where the at least one printing route is a substantially linear segment of a closed loop lane along which the objects are progressing.

Abstract: A printing apparatus for printing on a substrate comprises a first support to support a substrate support, and a second support that supports a print head, a ultraviolet (UV) source of UV radiation, and a gas dispenser. The second support is moveable relative to a substrate supported by the first support. The print head deposits printing fluid on the substrate and the UV source cures the deposited printing fluid. The gas dispenser is arranged to provide a layer of gas, which is at least depleted of oxygen, between the UV source and the substrate.

Abstract: An inkjet printing apparatus for printing on a substrate comprises a first support, which is a substrate support, and a second support which supports at least one inkjet printing head, at least one UV source of ultraviolet radiation, and at least one gas dispenser. The second support is moveable relative to a substrate supported by the first support. The printing head deposits ink on the substrate and the UV source cures the deposited ink. The gas dispenser is arranged to provide a layer of gas, which is at least depleted of oxygen, between the UV source and the substrate.

Abstract: According to one example of the present invention there is provided a printer for a printing on a roll of substrate. The printer comprises a substrate support for receiving a roll of substrate, a drive mechanism for driving substrate from a roll of substrate when installed on the substrate support through a print writing module, and a substrate edge trimming module for trimming the longitudinal edges of a substrate prior to the substrate passing through the print writing module.

Abstract: In an example this disclosure relates to printhead modules arranged to move with respect to each other.

Abstract: Systems and methods of controlling ink deposition during printing are disclosed. An example of a method includes actuating a plurality of print heads to deposit ink on a substrate. The method also includes activating an energy source to speed cure of the deposited ink on the substrate. The method also includes adjusting electrical output to the plurality of print heads to compensate for different distances from the energy source to each of the plurality of print heads.

Abstract: A printing apparatus for printing on a substrate comprises a first support for the substrate and a second support moveable relative to the first support. The second support supports an inkjet print head and at least one plasma source. The print head and plasma source move with the support to apply plasma to the substrate and to deposit ink on the substrate treated with the plasma.

Abstract: There is provided a printing device that includes an ink applicator and a shaping fluid outlet adapted to dispense a shaping fluid onto curable ink applied by the applicator. The printing device may further include energy emitting source used to at least partially cure the applied ink. There is further provided a curable ink mixture, the mixture includes a colorant at a concentration higher than 4%. There is further provided, a method for printing that includes applying curable ink on a substrate and shaping the ink by dispensing a shaping fluid.
