摘要： A continuous ink jet printer has a nozzle plate 1 which includes an orifice 3 for emitting a stream of ink. A counterbore 4 surrounds the orifice. A passage 5, 6 is provided which lies substantially in the plane of the plate and intersects the counterbore, and through which a flow of cleaning agent may be supplied to the counterbore, in order to flush ink from the surrounds of the orifice.

摘要： In a continuous ink jet printing method for printing multiple lines of print (13-15), raster of drops is produced in which the differential charge between drops printed on opposite sides of an interline gap (17,18) is increased in comparison with that between adjacent drops to be printed within a line (13-15). At the same time the number of guard drops is maintained the same or is reduced between the printable drops immediately adjacent to the interline gap, so that the distance between printed drops immediately adjacent to the interline gap is increased without increasing the number of drops in the raster.

摘要： A printhead (1) for a continuous ink jet printer has a single pair of nozzles (3,3'). One or more oscillators for vibrating the ink (3,3') may be used to break up the twin streams (4,4') of droplets issuing from the nozzles. A pair (5) of charging gates is provided for applying, selectively and respectively, a charge to droplets in the two streams (4,4'). A pair of deflector means (7) apply respective electric fields across the streams (4,4') to deflect the droplets individually in accordance with the charge thereon. A gutter (10) or pair of gutters (11,11') receive droplets from the respective streams if they are not charged. The arrangement is such that the two streams of droplets are deflected in opposite directions so as to be printed.

摘要： A method of and apparatus for controlling the velocity of a stream of droplets in a continuous ink jet printing system comprises controlling, from a system cabinet, the velocity of the stream expelled from the print head through a nozzle under pressure from a pressure source, in dependence upon a measured pressure of the ink in accordance with a predetermined relationship between the velocity and the pressure. On start up the system calibrates for the pressure differential P.sub.c due to the conduit length and the relative elevation of the print nozzle; and a determination of the ink viscosity in made at predetermined times. Thereafter the velocity is controlled in dependence upon a required pressure value P.sub.r in accordance with a stored look-up table, the required pressure value at any time being determined substantially by a given relationship.

摘要： A piezo-electric ink jet droplet generator (1) has a body part (2) having a first ink supply passage (10/11) and a second ink supply passage (12) extending generally perpendicularly therefrom through a protrusion (20) of the body and opening at an end face (14) of the protrusion. A piezo-electric crystal (6) is attached to a surface of the body closely spaced from the first ink supply passage and adjacent the end of the second ink supply passage which connects with the first supply passage. A nozzle (17) is mounted in a cap (3) which is secured to the end of the protrusion (20), the nozzle being in alignment with the second supply passage (12). The inner surface (13) of the cap surrounding the nozzle is spaced from the end face (14) of the protrusion thereby forming, in use, a disk (21) of ink between the inner face of the cap and the end face of the protrusion. The cap is sealed to the protrusion by means of a flexible seal ( 16) and engaged with the protrusion by means of a quick-release coupling (9,19).

摘要： A method of printing an image on a substrate effected by moving the substrate past a print head during a printing operation and printing the image by printing a plurality of strokes. Printing each stroke includes emitting a plurality of drops of ink from the print head. The method includes receiving image data defining an image to be printed, the image data including data relating to a characteristic of the image; selecting printer control data defining the plurality of drops of ink which are to be emitted from the print head to print a stoke, the selecting being based upon data indicating a maximum number of drops of ink which can be emitted from the print head during a stroke and the characteristic of the image; and printing the image based upon the data defining the image to be printed and the printer control data.
