<p>The method involves spraying a continuous jet of liquid (14) at a given speed (Yj), cause the jet to split at two distinct predetermined break points (C,L) so as to form drops (22,24) of liquid at a given emission frequency, and apply to these drops quantities of a different electrical charges, according to their break points. The same electrical field is applied onto the drops, so as to deviate only those drops (24) formed at a first (L) of the break points. The jet acted upon so that the two break points are separated by a distance DELTA D strictly less than the wavelength lambda of the jet, defined by the relation lambda = Vj divided by F. The same quantity of charge is applied on all the drops formed in a zone centered on the second break point (C) of length sensibly equal to lambda divided by 4. An Independent claim is also included for an ink jet printer using the method described.</p> |
