Claims (2)

  1. Une tête à jet d'encre pour un appareil d'enregistrement à jet d'encre comportant un substrat de formation de buses (30) dans lequel un ensemble de buses (31) sont formées, et un transducteur piézoélectrique (20) comprenant un ensemble de vibrateurs (20), ayant chacun au moins une extrémité fixe, qui sont disposés face à une buse correspondante (31) et qui peuvent être actionnés indépendamment les uns des autres, un intervalle étant formé entre le substrat de formation de buses (30) et les vibrateurs (21), et cet intervalle étant rempli par de l'encre,    la largeur (a) de l'intervalle dans une première région proche des buses (31) et entourant ces dernières, étant différente de la largeur (b) de l'intervalle dans une seconde région restante,    caractérisée en ce que    la première région a une longueur, depuis la position d'une buse (31), vers l'extrémité de vibrateur fixe, qui correspond à la moitié ou à moins de la moitié de la largeur (B) des vibrateurs (21).
  2. La tête à jet d'encre selon la revendication 1, dans laquelle la largeur (a) de l'intervalle dans la première région est inférieure à la largeur (b) dans la seconde région, lorsque la viscosité de l'encre est supérieure à 5 mPa.s, et la largeur (a) de l'intervalle dans la première région est supérieure à la largeur (b) dans la seconde région lorsque la viscosité de l'encre est inférieure ou égale à 5 mPa.s.
