Beschreibung
Zusammenfassung:	A media for ink jet printing is provided that improves the water fastness of the inks on the media, improves the absorption of aqueous inks into the media, and makes ink jet printed images on the media appear chromatic and clear. An ink/media set is also provided. The printing media is a fibrous fabric or sheet substrate that has been treated with a positively charged species to make pigments in such jetted inks strongly bind to the fibers of the media. Where appropriate, the printing media also includes a wetting agent to make the media readily absorb jetted inks. The media has high tensile and tear strengths making it suitable for outdoor signs and banners. L'invention concerne un support destiné à l'impression par jet d'encre améliorant la solidité à l'eau des encres sur le support, améliorant l'absorption d'encres aqueuses dans le support, et donnant à des images imprimées par jet d'encre sur le support une apparence chromatique et nette. L'invention a également trait à un ensemble encre/support. Le support d'impression est un substrat en tissu fibreux ou en feuille fibreuse ayant été traité avec une espèce à charge positive afin de faire en sorte que les pigments de ces encres à jet se lient fortement aux fibres du support. Lorsque cela est approprié, le support d'impression comprend également un agent humidifiant faisant en sorte que le support absorbe facilement les encres à jet. Le support présente des résistances élevées à la traction et la déchirure le rendant adapté à des panneaux et des bannières d'extérieur.
