CA 2506702
There is disclosed an inkjet printhead which comprises a plurality of nozzles (3) and one or more heater elements (10) corresponding to each nozzle (3). Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble (12) therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. The printhead has a substrate and each nozzle has a nozzle aperture opening through a surface of the substrate such that the areal density of the nozzle relative to the substrate surface exceeds 10,000 nozzles per square cm.
L'invention concerne une tête d'impression à jet d'encre comprenant une pluralité de buses (3) et au moins un élément chauffant (10) correspondant à chaque buse (3). Chaque élément chauffant est configuré de manière à chauffer un liquide de formation de bulles dans la tête d'impression à une température supérieure au point d'ébullition afin de former une bulle de gaz (12) à l'intérieur. La génération de bulles entraîne l'éjection d'une goutte d'un liquide éjectable (telle l'encre) à travers la buse correspondante respective, afin de déclencher l'impression. La tête d'impression possède un substrat et chaque buse est équipée d'une ouverture de buse à travers une surface du substrat de manière que la densité de surface de la buse par rapport à la surface du substrat dépasse 10.000 buses par cm?2¿.
