The invention concerns a measuring system in a fluid circuit of a continuous inkjet printer. According to the invention, a system for measuring the quantity of ink is realized using a continuous sensor (15) equipping a measuring tank (12), which is first emptied then connected by communicating vessel with an interme...

The invention relates to a preparation process for printing of light patterns on a dark background, on a surface (S) moving along a direction, using a set of jets in a print head, comprising the following for each jet in this set of jets: - an estimate of the disturbance on the print quality of this jet, resulting ...

The invention relates to a process for compensating for effects related to variations in the velocities of electrically charged ink drops (40) in a jet (4) output from a print head of a printer, the drops being electrically charged by charge electrodes (30), consisting of: – measuring the velocity of the jet on the...

The invention relates to a wide format print head composed of X inkjet print devices intended to print on a moving support and for which the print quality is to be improved over the entire width. The solution according to the invention consists of inputting a single air flow passing through the internal cavity o...

Ink composition for continuous deflected jet printing, that is liquid at ambient temperature, comprising a solvent containing less than 0.5% by weight of water and less than 0.5% by weight of alcohols relative to the total weight of the ink composition; one or more dye(s} and/or pigment (s) that is (are) insoluble i...
