Abstract

L'invention concerne un procédé de génération de gouttes pour une tête d'impression d'une imprimante à jets continus, cette tête d'impression comportant : - un générateur de gouttes, comportant une pluralité de chambres de stimulation (38), chacune associée à un activateur (35), - des moyens formant électrode(s), pour séparer des gouttes ou des tronçons d'un ou plusieurs jets, destiné(e)s à l'impression, des gouttes ou tronçons qui ne servent pas à l'impression, ces moyens ayant, le long d'une trajectoire non déviée des gouttes dans la cavité ; ledit procédé comportant : - l'application d'au moins 2 impulsions successives pour activer les moyens d'activation (35) d'au moins un générateur de gouttes, pour former au moins une goutte en amont des moyens (6) formant une ou plusieurs électrodes, - la formation de gouttes secondaires, par stimulation parasite, en aval de ces mêmes moyens formant électrode(s).The invention relates to a method for generating drops for a print head of a continuous jet printer, this print head comprising: - a drop generator, comprising a plurality of stimulation chambers (38), each associated to an activator (35), - means forming electrode (s), for separating drops or sections of one or more jets, intended (s) for printing, drops or sections which are not used for printing printing, these means having, along an undeflected path, drops in the cavity; said method comprising: - the application of at least 2 successive pulses to activate the activation means (35) of at least one drop generator, to form at least one drop upstream of the means (6) forming one or several electrodes, - the formation of secondary drops, by parasitic stimulation, downstream of these same means forming electrode (s).
