Beschreibung
Zusammenfassung:	The invention provides an ink jet printing apparatus (1000) that includes at least one ink jet print head (1002) adapted to dispense flu onto a substrate (S) and at least one delivery aperture (1006a or 1006b) adapted to direct a gas (from a gas supply 1010) toward the substrate. The apparatus may also include at least one recovery aperture (1008a or 1008b) adapted to draw materials away from the substrate and evaporate liquids from the surface of the substrate. L'invention concerne un appareil d'impression à jet d'encre comprenant au moins une tête d'impression à jet d'encre adaptée pour distribuer des fluides sur un substrat et au moins une ouverture de distribution adaptée pour diriger un gaz vers le substrat. L'appareil peut également comprendre au moins une ouverture de récupération adaptée pour aspirer les matériaux hors du substrat et faire évaporer les liquides de la surface du substrat.
