Claims (8)

1. Une plume à jet d'encre multicolore avec un haut et un bas, ayant une pluralité de groupes de buses (62a-62d), chacun d'entre eux comprenant une pluralité de buses, chaque groupe de buses ayant une longueur et une largeur prédéterminées et recevant une encre de couleur différente, caractérisée par le fait que les groupes de buses sont disposés les uns au-dessus des autres, chaque groupe de buses étant décalé latéralement par rapport à chaque groupe adjacent d'une distance au moins supérieure à ladite largeur pour minimiser la séparation verticale entre les groupes de buses adjacents tout en constituant une surface d'étanchéité autour de chaque groupe afin d'isoler les encres de couleurs respectives de chaque groupe de buses.
2. Une plume à jet d'encre selon la revendication 1 pour un appareil d'enregistrement pouvant être équipé soit d'une plume à jet d'encre à plusieurs chambres ou d'une plume à jet d'encre à une seule couleur, dans lequel la plume à jet d'encre à plusieurs chambres comporte un groupe (62a-62d) de buses (1, 2, 3, 4, etc.) connecté à chaque chambre (68a-68d) par un canal d'acheminement d'encre (68e-68h, 76a-76d, 64a-64d), les buses respectives de chaque groupe étant disposées selon un format correspondant à celui de la plume à jet d'encre à une seule couleur.
3. Une plume à jet d'encre selon les revendications 1 ou 2, dans laquelle chaque groupe de buses (62a-62d) comporte deux colonnes parallèles de buses (1-11, 2-12 ; 13-23, 14-24 ; 25-35, 26-36 ; 37-47, 38-48).
4. Une plume à jet d'encre selon la revendication 3, dans laquelle chacune desdites colonnes parallèles de buses (1-11, 2-12; 13-23, 14-24 ; 25-35, 26-36 ; 37-47, 38-48) dans un groupe de buses (62a-62d) a le même nombre de buses, une colonne de buses étant déplacée dans une direction le long de la colonne d'un demi espace de buse par rapport à l'autre colonne de buses, définissant un espace de ligne de points d'encre d'une rangée de points entre les buses correspondantes (11,12) dans les deux colonnes d'un groupe de buses mesuré dans une direction parallèle aux deux colonnes de buses.
5. Une plume à jet d'encre selon les revendications 3 ou 4, dans laquelle : chaque canal d'acheminement d'encre (68e-68h, 76a-76d, 64a-64d) est doté d'une ouverture (64a', 64b', 64c', 64d') à chaque groupe de buses (62a-62c) dans une position située entre lesdites deux colonnes parallèles de buses, ladite ouverture se projetant de manière substantielle le long de la longueur desdites colonnes de buses à l'intérieur du groupe de buses (62a-62d).
6. Une plume à jet d'encre selon l'une ou l'autre des revendications 3 à 5 pour l'appareil d'enregistrement, comprenant en outre un corps de plume (68) ayant une pluralité de chambres à encre (68a, 68b, 68c, 68d) ; une tête d'impression (60,66) ayant une pluralité d'orifices espacés (64a', 64b', 64c', 64d') à l'intérieur et un groupe de buses (62a, 62b, 62c, 62d), à chaque ouverture (64a'-64d') ; un moyen (76) de montage de ladite tête d'impression sur ledit corps de plume ; et un cavité de distribution (86b) entre chacune des deux colonnes parallèles de buses dans chaque groupe de buses, ladite cavité de distribution comportant une partie dudit canal d'acheminement d'encre et aboutissant à ladite ouverture (64a' ou 64b' ou 64c' ou 64d') et servant de moyen de communication entre ladite ouverture rt chaque buse desdites deux colonnes parallèles de buses.
7. Une plume à jet d'encre selon la revendication 6, dans laquelle le corps de ladite plume comprend : une plaque arrière commune à toutes lesdites chambres et dotées d'ouvertures respectives (68e-68h) la traversant pour déboucher dans les chambres à encre ; une plaque frontale (66) sur ledit corps de plume adjacente à ladite plaque arrière, sur laquelle ladite tête d'impression est montée et dotée d'ouvertures (64a-64d) la traversant et communiquant respectivement avec chacun de ladite pluralité d'ouvertures espacées ; et une plaque d'étanchéité (76) disposée et comprimée entre ladite plaque arrière et ladite plaque avant et dotée d'ouvertures la traversant (76a-76d) définissant des canaux individuels entre chaque ouverture et ladite plaque arrière et une ouverture correspondante dans ladite plaque avant, pour établir un canal d'acheminement entre chacune des chambres à encre (68a-68d) et le groupe de buses correspondant (62a-62d).
8. Une méthode d'utilisation d'une plume à jet d'encre selon toute revendication précédente, dans laquelle les buses (1,2,3,4, etc..) constituant le groupe de buses (62a-62d) sont allumées dans un ordre correspondant à l'ordre d'allumage des buses d'une plume à jet d'encre à une seule couleur contenant le même nombre de buses.
