An apparatus and process for curing UV-curable inks is provided comprising multiple printhead ejectors and ultraviolet light emitting diodes (UV-LEDs). The printhead ejectors are placed on the assembly in a geometry corresponding to the UV-LEDs such that when a printhead ejector deposits an ink droplet upon a substrate moving relative to the assembly, at least one UV-LED can pass directly over the ink droplet.

La présente invention concerne un appareil et un procédé pour le séchage d'encres à l'ultraviolet. L'appareil comprend plusieurs éjecteurs de tête d'impression et des diodes émettant de la lumière ultraviolette (UV-LED). Les éjecteurs de tête d'impression sont placés sur l'ensemble dans une géométrie qui correspond aux diodes UV-LED, de telle sorte que lorsqu'un éjecteur de tête d'impression déposée une gouttelette d'encre sur un substrat qui se déplace par rapport à l'ensemble, au moins une diode UV-LED peut passer directement au-dessus de la gouttelette d'encre.
